Ranging the GNSS Constellation
Laser ranging is an indispensable independent tool for validating the precise orbits determined for GNSS satellites using microwave pseudorange observations since decades. SLR allowed it to identify orbit modeling issues. Including albedo radiation pressure and antenna thrust, among others, into the GPS orbit model allowed it to basically eliminate the observed SLR bias. For the first Galileo s...
متن کاملA Wide Band Antenna for Multi-constellation Gnss and Augmentation Systems
Local Area Augmentation System (LAAS) based on multiconstellation GNSS can provide improved accuracy, availability and integrity needed to support all weather category II and III precision approach landing of aircraft. In order to receive satellite signals of GNSS, an antenna working over wide frequency band and high phase center stability is preferred. Commonly used antennas like crossed dipol...

متن کاملDynamic Reconfiguration in a GNSS Software Defined Radio for Multi-Constellation Operation
Recent advances in the US GPS constellation have resulted in additional signals being made available for both military and civil applications. The modernized GPS signal structure now includes signals broadcast on three frequencies with both the legacy GPS modulation codes, additional civilian codes, and also additional military codes on L1 and L2. In the next few years, GNSS users will also be ...
متن کاملDevelopment of a Real-time GNSS Software Receiver for Evaluating RAIM in Multi-constellation
As Global Navigation Satellite System continues to upgrade, there will be an increasing number of satellites and signals. This offers users benefits such as increased availability and improved diversity of signal. For safetyof-life users like aviation, higher availability of integrity is the key goal. A technology providing integrity with little or no ground infrastructure overhead is receiver ...
