N. K. Manasa, M. L. Badheka, V. K. Tank · 2017
This paper presents the design specifications adopted for the development of a research platform capable of handling L1-band(1575.42MHz), L5-band(1176.45MHz) and S-band(2492.028MHz) signals in RF Front end (RF FE) for Tri-band GNSS Receiver. The Tri band RF Down converter (TBDC) simultaneously receives IRNSS signals along with GPS signals and Output of the module is 70MHz IF which is after digitization fed to correlators for further processing in baseband processor as shown in the Fig. 1. This RF front end also and importantly receives Navigation signal as well.
