This paper presents the Mojave Desert field test results of planetary rover visual motion estimation (VME) developed under the "Autonomous, Intelligent, and Robust Guidance, Navigation, and Control for Planetary Rovers (AIR-GNC)" project. Three VME schemes are compared in realistic conditions. The main innovations of this project include the use of different features from stereo-pair images as visual landmarks and the use of vision-based feedback to close the path-tracking loop. The multiweek field campaign, conducted on relevant Mars analogue terrains, under dramatically changing lighting and weather conditions, shows good localization accuracy on the average. Moreover, the MDA-developed inertial measurement unit (IMU)-corrected odometry was reliable and had good accuracy at all test locations, including loose sand dunes. These results are based on data collected during 7.3 km of traverse, including both fully autonomous and joystick-driven runs. © 2012 Wiley Periodicals, Inc.

A direct adaptive control law is developed for a robust International Space Station attitude regulation during robotic capture of a free-flyer by the Space Station Remote Manipulator System. The proposed output feedback direct adaptive controller is developed from the Simple Adaptive Control theory, and makes use of the Modified Rodrigues Parameters. The performance of the adaptive controller is examined in MacDonald, Dettwiler and Associates Space Station Portable Operations Training Simulator; a high-fidelity multibody flexible dynamic simulation facility. SPOTS simulafion results are provided for an ISS free-flyer capture of a SpaceX Dragon-like space vehicle with the flexible SSRMS manipulator. Simulation results highlight the improved performance and robustness to parametric and dynamics modeling uncertainties of the proposed novel attitude control approach when compared with an attitude Proportional-Derivative controller.

We demonstrate here a computer code for calculation of time series and also mean and linear deformation rates from a set of coregistered unwrapped differential interferograms using a linear least-squares inversion technique based on the small baseline subset (SBAS) algorithm. The computer code is written in C and uses a singular value decomposition (SVD) routine from the LAPACK library and the fast Fourier transform for spatial filtering from the FFTW library. Various offset estimation and topographic correction algorithms are implemented, including simultaneous inversion for deformation rates and residual topographic error. This approach is particularly useful when applied to ALOS PALSAR interferograms that are coherent even at large perpendicular baselines and acquired with orbital parameters correlated with the time of acquisition. This methodology is applied to produce time series of ground deformation at Tauhara and Wairakei geothermal fields (Taupo Volcanic Zone, North Island, New Zealand) from 12 ALOS PALSAR images acquired between July 2007 and December 2009. We also present here a high-resolution deformation map of the ground subsidence caused by the extraction of geothermal groundwater for power generation, with maximum rates of subsidence of about 7. cm/y. © 2011 Elsevier Ltd.

An accurate understanding of the physical interactions and transport of space radiation is important for safe and efficient space operations. Secondary particles produced by primary particle interactions with intervening materials are an important contribution to radiation risk. Pions are copiously produced in the nuclear interactions typical of space radiations and can therefore be an important contribution to radiation exposure. Charged pions decay almost exclusively to muons. As a consequence, muons must also be considered in space radiation exposure studies. In this work, the NASA space radiation transport code HZETRN has been extended to include the transport of charged pions and muons. The relevant transport equation, solution method, and implemented cross sections are reviewed. Muon production in the Earth's upper atmosphere is then investigated, and comparisons with recent balloon flight measurements of differential muon flux are presented. Muon production from the updated version of HZETRN is found to match the experimental data well. © 2012 COSPAR. Published by Elsevier Ltd. All rights reserved.

RADARSAT remote sensing imagery can help to predict and mitigate against their effects . The most effective method for collecting spatial and temporal information for flood prevention, mitigation and response operations is data from remote sensing satellites. In use for decades, remote sensing satellite imagery is a proven technology that can identify those areas most at risk, and support effective flood prevention programs. Satellites can also deliver timely information on the scope and movement of floodwaters while an event is occurring, to better support assessment and rescue efforts. RADARSAT-1 and -2 are the worlds most capable, commercial SAR missions, with all-weather imaging day and night, superior capacity and tasking flexibility. Multiple imaging modes and selectable polarizations improve the qualitative nature of acquired scenes, and can be optimized to capture specific features or targets.
