Receiver Algorithms for the New Civil GPS Signals

Michael Tran and Christopher Hegarty

Abstract:	The United States is planning to implement two new civil signals on the GPS satellites in the next few years. The L2 Civil (L2C) signal will be implemented beginning with the first Block IIR-M satellite anticipated to be launched in 2003. The L5 signal will be implemented beginning with the first Block IIF satellite anticipated to be launched in 2005. Both new signals include design features that make them very different from the only existing civil GPS signal – the L1 C/A-code. This paper describes, in great detail, receiver algorithms for processing the L2C and L5 signals including code and carrier tracking loop implementations and digital pulse blanking mechanizations (for L5). The paper also provides performance evaluations for these algorithms, based upon analysis and simulation results.
