Lithospheric ultra low frequency (ULF) magnetic activity is recently considered as a very promising candidate for application to short-time earthquake forecasting. However the intensity of the ULF lithospheric magnetic field is very weak and often masked by much stronger ionospheric and magnetospheric signals. The study of pre-earthquake magnetic activity before the occurrence of a strong earthquake is a very hard problem which consists of the identification and localization of the weak signal sources in earthquake hazardous areas of the Earth's crust.

For the separation and localization of such sources, we used a new polarization ellipse technique (Dudkin et al., 2010) to process data acquired from fluxgate magnetometers installed in the Sichuan province, China. Sichuan is the region of the strongest seismic activity on the territory of China. During the last century, about 40 earthquakes with magnitude M ≥ 6.5 happened here in close proximity to heavy populated zones.

The Panzhihua earthquake M w Combining double low line 6.0 happened in the southern part of Sichuan province on 30 August 2008 at 8:30:52 UT. The earthquake hypocentre was located at 10 km depth. During the period 30-31 August - the beginning of September 2008, many clustered aftershocks with magnitudes of up to 5.6 occurred near the earthquake epicentre.

The data from three fluxgate magnetometers (belonged to China magnetometer network and placed near to the clustered earthquakes at a distance of 10-55 km from main shock epicenter) have been processed. The separation between the magnetometers was in the range of 40-65 km.

The analysis of a local lithospheric magnetic activity during the period of January-December 2008 and a possible source structure have been presented in this paper. © Author(s) 2011. CC Attribution 3.0 License.

Visually disabled people have striking needs for trustful navigation systems enabling for efficient mobility services, mainly considering safety and autonomy. In this context, satellite positioning and navigation technologies available are being implemented in innovative personal navigation devices. But existing products and solutions based on GNSS fail because they lack accuracy and integrity, they dont provide a suitable and efficient man-machine interface adjusted to this user segment, or rely on costly infrastructures.\nARGUS project focuses onto a satellite based navigation (GNSS/ EDAS) terminal for people with impaired visually capabilities, guiding them along pre-defined tracks (pre recorded or automatically calculated route), using specifically designed HMI such as acoustic and haptic signals. ARGUS project introduces the opportunity to develop an innovative guidance support system for visual impaired people based on the provision of a track perception to the end user through holophonic technologies. Neither research or patents, nor products, have solved the problem of providing a track line perception. Track perception would allow blind people to imagine the geometry of the path and walk along it. This will provide track navigation instead the classical waypoint or route navigation which is used for car navigation or people with all visual capabilities. This project focuses on visually impaired community which requires some modification to the traditional navigation guidance providing them personal inclusion and integration into daily life. Information collected by the users, will be gathered in a server supporting a social network where Argus users (and also any other user who could benefit from the data collected) could access web services delivering useful information that can increase safety or enhance the experience when performing outdoor activities.\nThe user groups identified for ARGUS are visually impaired people, covering all levels of visual impairment, and also people working in environments with low visibility. Elderly people could in many occasions be included among such groups.

Lane-level positioning and map matching are some of the biggest challenges for navigation systems. Although vehicle telematics provide services with positioning requirements fulfilled by low-cost GNSS receivers, more complex road and driver assistance applications are increasingly been deployed, due to the growing demand. These include lane-level information as well as lane-level navigation and prioritised alerts depending on the scenario composition (traffic sign, navigation instructions, ADAS instructions). These applications need a more accurate and reliable positioning subsystem. A good example of these new requirements can be witnessed in the increasing interest in navigation at lane-level, with applications such as enhanced driver awareness, intelligent speed alert and simple lane allocation. As well as the accuracy of positioning data being a big driver, there is also a question around the adaptability of navigation systems to these applications. This depends firstly on the availability of an accurate common reference for positioning (an enhanced map) and secondly, on the level of the provided pose estimation (integrity). However, neither the current road maps nor the traditional integrity parameters seem to be well suited for these purposes. Delivering lane-level information to an in-vehicle navigation system and combining this with the opportunity for vehicles to exchange information between themselves, will give drivers the opportunity to select the optimal road lane, even in dense traffic in urban and extra-urban areas. Every driver will be able to choose the appropriate lane and will to be able to reduce the risks associate with last-moment lane-change manoeuvres. inLane proposes new generation, low-cost, lane-level, precise turn-by-turn navigation applications through the fusion of EGNSS and Computer Vision technology. This will enable a new generation of enhanced mapping information based on crowdsourcing.

A Volumetric Navigation System (VNS) started with great interest in new traffic navigation solutions considering certain scenarios in which all the vehicles share information in order to be part of a collaborative navigation network. In those scenarios, 3D volume dimensions are used to define the position of an associated volumetric envelope in time. In the maritime navigation the volume of the ship is the envelope of the ship after a given time.Horizontal dimensions of this ships envelope will consider his current speed and also from his extreme stopping and manoeuvring capabilities from the given speed and load, and correction for the drift due to local measured wind and mapped currents. The vertical dimension in navigation at sea is the water distance below the keel at fore and the aft of the ship and the sea bottom as given by carthography and tide. The display may overlap the Electronic Chart Display and Information System (ECDIS) screen.VNS is a human error avoiding tool for collision avoidance, manouevring and navigation in low separation traffic lines and channels, crossings, port traffic, congested shallow waters. The system key points are: Every vessel may be represented by a safety volume envelope which geometry will depend on its real shape, navigation and dynamical parameters and the surrounding environment; The position and course and heading of a vessel may be accurately calculated in real time from its position, speed and drift by GPS and GNSS technologies. Combining position, course, drift and volume, each vessel may be considered as a geo-referenced geometrical volume; In an scenario with different ship sizes and tonnage and speeds each vessel or boat generates his own volume that is transmitted to the other vessels in the area . The shore, docks river or channel sides and shallow water obstacles generate a warning when the volume of the vessel approaches at different levels of risk .

Strong need for a sophisticated landslide monitoring and alerting system has grown especially in mountainous regions. Traditionally, monitoring is performed using time-domain reflectometry by geodesists. Since a few years the Global Positioning System (GPS) dual-frequency Real-Time Kinematic (RTK) approach is widely used for monitoring landslides. However, it should be noted that the setup and the support of dual-frequency RTK is cost intensive. In order to reduce the costs of a GPS-based landslide monitoring system, one could use single-frequency low-cost receivers for RTK or try to utilize a Precise Point Positioning (PPP) approach. A landslide monitoring system using both single-frequency RTK and PPP is developed by Graz University of Technology and TeleConsult Austria GmbH within the GeoWSN project. This paper describes the general structure of a GPS-based landslide monitoring system and discusses aspects of the used PPP approach. © 2012 IEEE.

Many GNSS applications require both, fast and trusted positioning. For example, in road toll collection this two requirements are extremely critical in order to provide fair road fee charges. One of the most effective measure to shorten the time to first fix is the usage of an assistance server to provide actual ephemeris and almanac information to the user. On the another hand, information from the assistance server can also be used as trusted reference data, which can help to detect spoofing attacks. The drawback is that a permanent connection to assistance server is required, in order to retrieve the latest ephemeris and almanac data. To overcome this problem the assistance server must be able to calculate and provide predicted orbits having a validity over a long period (e.g., up to 1-2 weeks). This paper describes a modular and cost-effective GNSS orbit prediction algorithm for reducing time to first fix as well as trusted positioning. The presented algorithm is implemented in the Positioning And Navigation Data Assistance Server, developed by TeleConsult Austria GmbH. © 2012 IEEE.
