Abstract

Software Global Navigation Satellite Systems (GNSS) receivers are those that implement signal correlation processing not in hardware, but in their software. The main problem for the development of real-time software (SW) multichannel GNSS receivers is the tremendous amount of calculations to perform signal correlation.

The article reviews recent developments of SW GNSS receivers. The emphasis is made on the computationally effective correlation processing algorithms and the optimization of processing allocation to the receiver's hardware (HW) and SW.

An architecture is suggested that implements the PRN signals despreading in a special HW preprocessor while all the other correlation processing functions are still kept in SW. The combination of the most time-consuming processing in HW, and all signal structure-dependent processing in SW, enables unique flexibility of sophisticated GNSS receiver design based on inexpensive digital signal processors. © 2000 John Wiley & Sons, Inc.
