GM-R800 GPS Receiver
EverMore GM-R800 series is a high sensitivity GPS receiver , This product is based on
Atmel chipset in 16 channel GPS receivers solution. The GPS module receiver will track
up to 16 satellites at a time while providing fast time-to-first-fix and 1Hz navigation
updates. It is far reaching capability meets the sensitivity & accuracy requirements of
car navigation as well as other location-based applications, such as AVL system. PDA,
Notebook operated navigation system.
The GM-R800 design utilizes the latest surface mount technology and high level circuit
integration to achieve superior performance while minimizing dimension and power
consumption. This hardware capability combined with software intelligence makes the
board easy to be integrated and used in all kinds of navigation applications or product s.
The module communicates with application system via RS-232 level with NMEA-0183
protocol.
