Positioning GPS - SL871-S and SL871L-S

 

 

Compact, low-power GPS system

The compact SL871-S supports both GPS and QZSS constellations and is pin-to-pin compatible with its GNSS companion, the SL871. Developers can take advantage of features such as an ARM7 baseband processor, embedded ROM and integrated LNA. It delivers positioning data via standard UART and an ultra-sensitive RF front-end which enables superior navigation performance in challenging environments with poor sky visibility.
