MAXREFDESGPS_B: How to Add GPS to your Product without Draining your Battery



The GPS reference design is an evaluation kit designed to demonstrate the essential features of an ultra-low power GPS (global positioning system) receiver, as well as serving as a reference design to illustrate how to implement such a receiver rapidly. The reference design uses the MAX2769C L1-band GNSS RF front end IC (RFIC) from Maxim Integrated, and the ultra-low power GPS baseband processing firmware provided by Baseband Technologies Inc. (BTI) that runs on a MAX32632 microcontroller unit (MCU).
