A new GNSS receiver and remote sensing instrument has been developed by SSTL and partners. Global Navigation Satellite Systems (GNSS), which include both the GPS and Europe's fledgling Galileo systems, radiate signals at the Earth from orbit. Beyond the every day application of navigation, these signals can also contain information that is valuable to scientists interested in studying the Earth from space. Information about the Earth's atmosphere and Ionosphere can be derived using a technique known as GNSS Radio Occultation (GNSS-RO), whereby signals that pass through the Earth atmosphere are received by a small satellite orbiting in a Low Earth Orbit (roughly 400-800km) and then looking at the distortions on those signals. GNSS Reflectometry (GNSS-R) is a relatively new application and this technique seeks to derive information about the Earth by looking at GNSS signals that have been reflected off the Earth's surface and subsequently received by a satellite in low Earth orbit. In the process of reflecting, these signals are distorted by the reflecting surface and, through the use of inversion models, it is possible to subsequently derive information about that surface from the signals. The driving application for this development is the monitoring of the Earth's oceans and, in particular, information about ocean roughness and wind speeds could be derived. Reflections off land and ice have also been detected and potentially contain a wealth of useful information. The concept has been proved on an experiment flown on SSTL's UK-DMC mission, but more data from orbit is required to improve the models that will allow this technique to become a useful tool to scientists. At its heart, the GNSS-RSI is a highly versatile, multi-frequency GNSS navigation receiver. With the addition of multiple front-ends, reconfigurable DSP capabilities, a small data recorder and specialised antennas, the GNSS-RSI enables both Reflectometry and Radio Occultation applications. Building on SSTL's small satellite expertise and using state of the art technology, the instrument aims to provide a highly capable yet relatively compact and affordable way of studying the Earth from orbit.

Black engineering graduates are less likely to find jobs than white students with lower second or third class degrees, according to a report that reveals stark inequalities within the profession. The review, by the Royal Academy of Engineering (RAEng), found that being black or minority ethnic was a bigger obstacle to employment than any other factor considered, including degree classification, attending a less prestigious university or gender. Bola Fatimilehin, the academy’s head of diversity, said an old boys’ network approach to recruitment and unconscious biases were contributing to the challenges faced by non-white students. “There is a certain amount of stereotyping of who can be an engineer and what talent looks like,” she said. “A lot of people fall into the mode of thinking that there aren’t a lot of black engineers because [black people] are not interested in it.” The analysis found that 71% of white engineering graduates were in full-time jobs within six months of leaving university, compared with just 52% of Asian students and 46% of black students. When gender, age, class of degree and type of institution were taken into account, black and Asian graduates were more than twice as likely to be unemployed as their white counterparts. The figures highlight an apparent paradox in which government and industry leaders have consistently pointed to a national shortage of engineers, while a high proportion of black and ethnic minority graduates are failing to find jobs. Indeed, the science minister, Jo Johnson, noted “the chronic shortages of engineers that have long held our economy back” in a comment article last month. The shortage of engineers is often cited as an incentive to attract more women into the profession – just 12-15% of engineering undergraduates are female. “That’s true, but what about the missed opportunity with all these graduates from ethnic minority backgrounds?” said Fatimilehin. “It feels like a low hanging fruit.” Gender has dominated the diversity agenda in engineering for the past decade, but the report found that it only has a minor influence on immediate employment prospects for graduates. Women were slightly less likely to enter engineering occupations after university, but more likely to pursue further study. The focus on “getting girls into engineering” has led to the lack of progress on racial diversity being overlooked, according to Fatimilehin. “People come back to gender because it feels safer,” she said, adding that male engineers tended to get behind the idea that women face additional barriers because most would have a wife, daughter or female friend. “They’re less likely to have a friend who is black,” she said. The RAEng report puts forward several possible explanations for the findings, which were based annual destination surveys of around 250,000 students by the Higher Education Statistics Agency (HESA). Engineering firms often recruit from Russell Group universities, which on average have lower proportions of ethnic minority students. However, even when institution type is taken into account there is a gulf between the employment prospects of white students and black and Asian ones. “This suggests statistically that ethnicity itself is correlated with an unemployment outcome, and is a stronger effect than any of the other factors studied,” the report concluded. According to Fatimilehin, unconscious bias, preconceptions about who will “fit in” with company culture and people “recruiting in their own image” also play a role. “The chief execs say ‘there’s nobody out there’,” she said. “There are people out there. As a society we need to get better at looking for people, rather than just accepting that a certain type of black person doesn’t exist.” Anita Bernie, director of spacecraft platforms at Surrey Satellite Technology Ltd (SSTL), said she was “amazed” by the gulf in career prospects between white and ethnic minority students. Bernie, who is black, said that SSTL has a diverse mix of ethnicities and that most of her current team are female. “When I go to other companies, the mix in terms of gender and ethnicity is very different,” she said. Bernie agreed that employer recruitment bias is likely to be a problem. “It’s partly human nature that you tend to want to recruit people like you,” she said. “It’s really easy to see a young white lad come in and think ‘I used to be like that’. I do think that exists in other companies.” Rebecca Hilsenrath, chief executive of the Equality and Human Rights Commission said: “It is shocking that black and minority ethnic people with degrees are still not getting the same job opportunities as others. This suggests we have a long way to go to create the equal society the prime minister talked about on the steps of Downing Street.” An EHRC report published earlier this year found that the life prospects for young black and minority ethnic people have got much worse over the past five years and are at their most challenging for generations. On average, black, Asian and ethnic minority workers with degrees are two-and-a-half times more likely to be unemployed than white workers with degrees, the report found. Belinda Phipps, CEO of the Science Council, welcomed the RAEng review, saying it was important to highlight inequalities in the profession. “From the moment a baby is born its life is shaped by the enforcement of stereotypes: girl children are taught they must be clean and quiet; those of certain ethnic origin are expected not to succeed,” she said.

Europe has extended its satellite-navigation system by putting another four spacecraft in orbit. They went up on an Ariane 5 rocket from French Guiana, leaving the ground at 10:06 (13:06 GMT). It is the first time Europe's premier launch vehicle has been used to loft Galileo satellites. Normally, they go up on a Russian Soyuz, two at a time. Mission success was declared once the quartet had been safely ejected from Ariane's upper-stage. Controllers immediately made contact with the satellites and confirmed their solar panels were deployed and generating power. That is six short of the planned number for the full network, but more than enough for Galileo to start an initial service, which it is expected to do in the next few weeks. When that happens, the very latest smartphones and other types of receivers should start picking up the system's signals - either to get a position fix or to make use of its embedded timing information. "From a technical standpoint we are ready, and the performance is excellent," said Paul Verhoef, director of navigation programmes at the European Space Agency (Esa). "There are still some small issues that need to be addressed and some formalities that need to be settled, and one of those is making sure the security is in place so that the system is properly protected when the service starts," he told BBC News. A project of the European Commission and the European Space Agency 24 satellites constitute a full system, but it will have six spares in orbit also Spacecraft have been launched in batches of two, but now go four at a time Galileo will work alongside the US-owned GPS and Russian Glonass systems Completed Galileo promises real-time positioning down to a metre or less It should deepen and extend high-value markets already initiated by GPS Esa is acting as technical adviser and procurement agent on Galileo, which is formally owned and funded by the European Commission. The EU is investing billions in the sat-nav project, to both complement and rival the Americans' Global Positioning System (GPS). Galileo's next-generation technologies are designed to provide users with quicker, more reliable fixes, enabling them to locate their positions with a general error of one metre, compared with the current GPS error of several metres. The Commission hopes Galileo will bring significant returns to member-state economies in the form of new businesses that can exploit this better precision and the guarantees that will come with the new civilian-run service. The latest spacecraft were produced by the German-UK consortium of OHB System of Bremen and Surrey Satellite Technology Limited (SSTL) of Guildford. OHB made the bus, or chassis, for each satellite; SSTL's role was to assemble the navigation payload - the "brains" of every Galileo spacecraft. OHB-SSTL have been the primary suppliers of the satellites to date, and by the time their current work order is complete they will have produced 22 of the 26 platforms ordered by the EC and Esa. The next contract, which could comprise eight or more satellites, will be announced shortly. A fully operational Galileo system is regarded as a constellation of 24, split across three orbital planes in the sky. But spares are required also, and with one existing satellite already considered close to failure, the EC has to make allowance for near-continuous production. Certainly, the German-UK pairing want to keep their engineers busy. "At SSTL, it has a been a fantastic journey for us," said company CEO, Patrick Wood. "If you think back to 2005, we launched the very first satellite, called Giove-A, to claim the frequencies for Galileo; and since then we've worked on 22 satellites and our navigation capability is now recognised to be world-beating. We want to continue that." These are, though, nervous times in the UK space sector, as it wonders what sort of relationship Britain will have with the EU, post Brexit. The type of involvement SSTL has in Galileo touches on matters of security, and the company would not be permitted to keep its role if the UK makes a clean break from the Union with no buy-back into the programme. Other British companies currently working on Galileo are in a similar position. The EC is in the process of deciding where to place contracts not just for future satellites, but also in the realms of operations, system engineering and ground control. However, Brussels is obliged for the moment to treat all tenders exactly the same - whether from the UK or from firms based in the 27 remaining EU member states. Mr Verhoef stressed that nothing changes until Brexit negotiations are complete. There could be no contracts awarded on the basis of politics, he told BBC News. "It would be illegal; somebody could take us to court and they would win immediately," he said. Jonathan.Amos-INTERNET@bbc.co.uk and follow me on Twitter: @BBCAmos

Twinkle is a space mission dedicated to the observation of the atmospheres of extrasolar planets (planets orbiting other stars) through the use of optical and infrared spectroscopy. The study of exoplanets has been incredibly successful over the past 20 years: nearly 2000 planets have been discovered in our galaxy, and along these discoveries fundamental parameters such as the planetary mass, size and distance to the parent star have been acquired. In the past decade, pioneering results have been obtained using transit spectroscopy with the Hubble and Spitzer Space Telescopes and ground-based facilities, which have enabled the detection of a few of the most abundant chemical species, the presence of clouds, and have also permitted the study of the planetary thermal structure. The next step is Twinkle: A small dedicated satellite designed to understand these newly found worlds through the measurement of their atmospheric signatures. Twinkle will observe the chemical composition and weather of at least 100 exoplanets in the Milky Way, including super-Earths (rocky planets 1-10 times the mass of Earth), Ncptunes, sub-Neptunes and gas giants like Jupiter. Twinkle is a cost-effective space mission taking advantage of lowered costs of access to space. The Twinkle satellite is being built in the UK and will be launched into a low-Earth sun-synchronous polar orbit by 2019, using flight proven spacecraft systems designed by Surrey Satellite Technology Ltd and high TRL instrumentation built by a consortium of UK institutes. The Twinkle instrument will be composed of a visible-IR spectrograph (between 0.5 and 5pm) with resolving power R-300. The funding for Twinkle will be provided through a combination of private and public sources.

WEST PALM BEACH, Fla., Dec. 05, 2016 (GLOBE NEWSWIRE) -- Ocwen Financial Corporation, (NYSE:OCN) (“Ocwen” or the “Company”), a leading financial services holding company, today announced the completion of the settlement of the previously announced Exchange Offer by its subsidiary Ocwen Loan Servicing, LLC (“OLS”) pursuant to which OLS issued $346.9 million aggregate principal amount of 8.375% Senior Secured Second Lien Notes due 2022 (the “New Second Lien Notes”) in exchange for $346.9 million aggregate principal amount (or 99.1%) of Ocwen’s 6.625% Senior Notes due 2019 (the “Existing Notes”) that had been tendered in the Exchange Offer. The Exchange Offer was purely a debt-for-debt exchange offer and none of OLS, Ocwen or any of their subsidiaries received any cash proceeds from the transaction. Ocwen also announced that concurrently with the closing of the Exchange Offer, OLS entered into a new Senior Secured Term Loan Facility (the “SSTL”), with an initial interest rate of 6.0%. The SSTL provides for a $335 million term loan credit facility with a maturity date of December 5, 2020, and is refinancing the prior senior secured term loan that had a maturity date of February 15, 2018 and an interest rate of 5.5%. The SSTL refinancing was predominantly a debt-for-debt refinancing and, after allowing for payment of expenses on both transactions and original issue discount on the SSTL refinancing, none of OLS, Ocwen or any of their subsidiaries received net cash proceeds from these transactions. “We are very pleased to have successfully completed these two important refinancing transactions,” commented Ron Faris, President and CEO. The SSTL and New Second Lien Notes are jointly and severally guaranteed by Ocwen, Ocwen Mortgage Servicing, Inc., Homeward Residential Holdings, Inc., Homeward Residential, Inc. and Automotive Capital Services, Inc. (collectively, the "Guarantors"). The New Second Lien Notes and the related guarantees will be unsubordinated obligations of OLS and the Guarantors, respectively, and will be secured (subject in each case to certain exceptions and permitted liens) by a second-priority lien on the assets of OLS and the Guarantors that secure the SSTL (the "Collateral"). The lien on the Collateral securing the New Second Lien Notes will be junior to the first priority lien securing the SSTL. The New Second Lien Notes have not been registered with the Securities and Exchange Commission (the "SEC") under the Securities Act of 1933, as amended (the "Securities Act"), or any state or foreign securities laws. The New Second Lien Notes may not be offered or sold in the United States or to any U.S. persons except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act. In the settlement of the Exchange Offer, OLS delivered the Total Exchange Consideration of $1,000 principal amount of New Second Lien Notes for each $1,000 principal amount of Existing Notes that were validly tendered in the Exchange Offer, including Existing Notes that were tendered after the Early Tender Date of 5:00 pm on November 15, 2016.

Having revolutionised the Earth Observation market with its low cost Disaster Monitoring Constellation (DMC) and novel international imaging business model coordinated by Disaster Monitoring Constellation International Imaging Limited (DMCii), SSTL outlines in this paper a concept for extending this approach to the geostationary communications market by facilitating partnerships where the purchase of a single satellite will provide access to all the combined assets. By this means all countries in Africa can reap the social and economic benefits of universal television and internet services. In modern society television is recognised as fundamental to social cohesion, providing information, education and shared entertainment. Provision of television to the whole population with locally produced content and news in all national languages is an essential national goal. Increasingly, universal internet access is seen as a second essential for economic growth, social interaction and delivery of government services. Delivery of these goals by terrestrial television (TV) transmission and by fixed lines is unaffordable for many wealthy nations. For developing economies, infrastructure may be affordable only for the largest cities and towns. Satellite delivery of television is a profitable and rapidly expanding business but benefits primarily the wealthy in a developing economy despite its national coverage. Mostly, transponders are leased at high cost. Efficient high throughput satellites (HTS) now offer tenfold lower cost transponders than standard broadcast satellites but cost over $300M each in orbit and must be spared for reliability. In this paper it is shown that both television and internet can be provided on the same HTS by optimising user cache and by non-linear delivery of pre-recorded content. Once free of the standard linear television model, satellite capacity can be shared over time between regions or nations following a pre-arranged schedule. A novel system is detailed covering both space and ground segments. A single modified HTS satellite allows universal service over a whole continent. The system may be built step by step, with the addition of further identical satellites in two or more orbital slots to provide ever greater capacity, availability and flexibility. Ownership can be much cheaper than leasing over satellite lifetime but the current cost is unaffordable to many nations. To facilitate new entrants, SSTL has halved the entry cost for a fully performant HTS using an innovative payload with standard equipments on its GMP geostationary platform. In this paper the continued development of the GMP platform to offer improved capability at low cost will be outlined. To further reduce initial costs, SSTL will introduce cost sharing partners with a compatible technology demonstration payload on each satellite.

Following an announcement by the European Commission in January 2010, ESA's contract for the provision of the first batch of 14 Galileo satellites is now underway. The OHB-SSTL team building these satellites has OHB responsible for the satellite platforms (buses) and SSTL responsible for the navigation payloads. The electrical architecture of the bus uses a MIL-STD-1553 architecture whereas this standard is not used as the interface to the payload units which are being procured by SSTL. Consequently, the need arises for a remote terminal unit (RTU) acting as the data gateway between the 1553 bus and the payload units. In 2009 SSTL commenced the design of this RTU and this paper details the design of both the hardware and the embedded software.

Silkmoths of bivoltine, native of temperate countries, lay diapause eggs that can be preserved safely for 20-300 days to postpone hatching by adopting suitable preservation schedules. The embryos are isolated from the eggs by adopting Potassium hydroxide method. Egg cards are dipped in boiling 2-4% Potassium hydroxide (KOH) solution in a beaker for 20-30 seconds, and then washed in water at 60°C. The contents are transferred to water maintained at room temperature. The embryonic age at the time of egg preservation at 5°C is found to be stage-17 and it reaches stage-18 when the eggs are shifted to 15°C for 2 days. Farmers were randomly selected from 13 villages in Chintamani and 9 in Malavally area. A total quantity of 3446 dfls preserved for 50 days and 3980 dfls were tested with 18 and 17 farmers, respectively.
