SIGNAL: Mission Concept and Performance Assessment
نویسندگان
چکیده
SIGNAL (SAR for Ice, Glacier and oceaN globAL dynamics) is a proposal for an innovative Earth observation mission, under study at German Space Agency. The mission objectives include the determination of ice topography and its temporal changes, the monitoring of fast-flowing glaciers, and the characterisation of ocean currents, by using Ka-band synthetic aperture radar (SAR). Two approaches to the mission, including a single satellite with multiple antennas and two free flyers, are presented and critically discussed. A preliminary performance analysis for the key mission measurements has been performed and will be presented.

A Novel Satellite Mission Concept for Upper Air Water Vapour, Aerosol and Cloud Observations Using Integrated Path Differential Absorption LiDAR Limb Sounding
We propose a new satellite mission to deliver high quality measurements of upper air water vapour. The concept centres around a LiDAR in limb sounding by occultation geometry, designed to operate as a very long path system for differential absorption measurements. We present a preliminary performance analysis with a system sized to send 75 mJ pulses at 25 Hz at four wavelengths close to 935 nm,...
متن کاملHolistic Contingency Management for Autonomous Unmanned Systems
Contingency Management—the problem of recognizing, assessing, and responding to unanticipated events or conditions that impact plan execution—is a key enabler for unmanned systems to become autonomous systems—that is, able to carry out assigned tasks or missions without continuous human supervision. We present a concept and technology for holistic contingency management that addresses all level...
متن کاملA New Vision-Based and GPS-Signal-Independent Approach in Jamming Detection and UAV Absolute Positioning Assessment
The Unmanned Aerial Vehicles (UAV) positioning in the outdoor environment is usually done by the Global Positioning System (GPS). Due to the low power of the GPS signal at the earth surface, its performance disrupted in the contaminated environments with the jamming attacks. The UAV positioning and its accuracy using GPS will be degraded in the jamming attacks. A positioning error about tens of...

متن کاملStatistical Analysis of Ambiguity to Signal Ratio Levels based on Global Backscattering Maps
Ambiguities are one of the limiting factors of SAR product quality and are thus important subject to every mission performance analysis. Since target NRCS is highly heterogeneous, the resulting ambiguities affect different areas at very different levels. Therefore using global average ambiguity levels for product performance assessment is of limited use. In this paper we present a statistical a...
