Abstract:	Pseudo-Lm is the signal structure designated by the GPS JPO for use in the next generation of satellite navigation signal simulators that implement the modernized military signals. This paper presents the architecture of a software Pseudo-Lm GPS receiver. A realistic RF environment is generated by the signal simulator and passed to the software receiver to provide completely flexible, repeatable navigation system evaluation. The software digital receiver is implemented using modules that are easily configurable through a user-friendly graphical user interface. Both C/A, P and Pseudo-Lm receivers have been implemented and their performances compared. The peculiarities of the Pseudo-Lm receiver architecture are emphasized. Some of these issues involve matched filtering and correlation, correlator spacing, acquisition techniques, carrier tracking, response to jamming and interference, etc.
