Dual-Frequency Receiver Technology for Mass-Market Applications

Taymoor Hekmat and Guenter Heinrichs

Abstract:	Considering both the rapid expansion of the mass-market applications of satellite navigation, and the future civil frequencies of modernized GPS and European Galileo, dual-frequency low-cost receivers will be introduced all over, where they are commercial feasible while providing value-added functionality. This paper presents primary the additional complexity of a dual-frequency satellite navigation receiver related to the single-frequency one. Then for each receiver part, from the antenna and frontend to the digital signal processing unit, the possible technologies for a dual frequency low cost receiver, which minimize the cost gap between the single and dualfrequency solutions, will be presented and discussed. It will be shown that digital signal processing and navigation solution finding affect just marginally the cost increase of the receiver. The front-end and antenna, by contrast, remain the critical parts in designing low-cost dual frequency receivers.
