This is an improved method of processing without knowledge of the encryption code.A method of processing signals in a Global Positioning System (GPS) receiver has been invented to enable the receiver to recover some of the information that is otherwise lost when GPS signals are encrypted ... In comparison with prior such methods,

In this paper, an equivalent GPS P-code simulator model is proposed to facilitate design and verification. In addition, a group of mathematical equations are developed to implement a flexible P-code generator, which can start running from any specific time of a week.

The reported direct GPS P-code acquisition algorithms are based on either time domain correlators or FFT search. The direct P-code acquisition in time domain needs massive physical correlators in parallel for code search [3], which requires lots of resources for hardware implementation.

The user-exit program, ue4, receives and stores the ADCP data along with both the P-code navigation data from AOML's Trimble receiver and the Ashtech gps receiver, which accounts for pitch and roll. The P-code data are used as navigation for the ADCP processing.
