Analysis of Influences due to Navigation Message Error of GPS Signals on Receiver [PDF]
The Journal of the Korean Institute of Information and Communication Engineering, 2010 The integrity monitoring of anomalous GPS signal have been researched because of the degradation of GPS satellite performance. It is known that anomalous GPS signal can occur by failure of GPS satellite, sudden increase of ionosphere delay error, SA, wrong modeling for navigation parameters from control segment, and an electromagnetic wave interference,

Partial CRC-assisted error correction of AIS signals received by satellite
2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2014 This paper deals with the demodulation of automatic identification system (AIS) signals received by a satellite. More precisely, an error correction algorithm is presented, whose computational complexity is reduced with respect to that of a previously considered approach.
