The SoftFlex approach in the user equipment for satellite navigation: Examples of application

This paper presents the examples of successful application of the method which reduces load on central processing unit (CPU) of the satellite navigation user equipment. The idea behind the method is to save CPU resources by using only partial set of the input samples during signal processing. The method was used to implement a software correlator in the spaceborne MosaicGNSS receiver and to improve performance of the GPS/GLONASS receiver produced by Mstar Semiconductor (Taiwan) for consumer market.
