GNSScope and the split chip compression technique

By Renan Kazazoglu, Ediz Cetin and Izzet Kale


The presence of multipath due to obstructions on the signal path coupled with transmitter and channel based perturbations, can significantly degrade the quality of the received satellite navigation signals, resulting in the non-detection of weaker visible satellites, loss of lock on acquired satellites, and increased pseudo-range errors. In this paper, we present a novel technique based on the binary-valued signal compression method, for the detection, identification and compensation of pseudo ranging code discrepancies and signals on the multipath. Following a brief overview of the system, simulation case studies carried out entirely using the in-house developed satellite navigation receiver development, emulation and analysis platform Global Navigation System Scope (GNSScope) will be presented verifying the results
