It offers very low current consumption, high sensitivity, and best in class signal acquisition and time-to-first-fix performance. The Venus634FLPx contains all the necessary ponents of a plete GPS receiver module, includes GPS RF front-end, GPS baseband signal processor, 0.5ppm TCXO, 32.768k Hz RTC crystal, RTC LDO regulator, and passive ponents. It requires very low external ponent count and takes up only 100mm2 PCB footprint. Dedicated massive-correlator signal parameter search engine within the baseband enables rapid search of all the available satellites and acquisition of very weak signal. An advanced track engine allows weak signal tracking and positioning in harsh environments such as urban canyons and under deep foliage. Programmable flash-based memory makes it ideal for applications requiring customized firmware.
