AbstractThe design and development of a digital signal processing based module to pre-process raw GPS data is proposed. Using frequency domain techniques to aid tracing loop, conventional receiver could maintain lock with narrow bandwidth at 90 g of acceleration and 90 g/s of jerk or more, as well as rapidly acquire the P(Y)-code directly. This technology has been studied and tested since the mid 1980s and is now ready for implementation as the next innovation in digital GPS. This approach also provides the ability to suppress jamming.This technology is also directly applicable to develoing a fully DSP-based frequency domain GPS receiver for high dynamcis and fast acquistion in jamming environments. Prototype receivers have been developed and tested for high dynamic tracking, and there was a frequency domain receiver for use on missiles developed and manufactured by a foreign nation. Frequency domain methods are also beginning t find there into new GPS receivers for fast, direct P(Y)-code acquisition in a jamming environment. However, there is a not single receiver that combines all these properties into a single unit, and this is proposed here as a follow on to the preprocessor, which would be a module the full receiver.
