The ADH-Tech GP-2117 is a complete GPS & GLONASS engine module that features super sensitivity, ultra low power and small form factor. The GPS & GLONASS signal is applied to the antenna input of module, and a complete serial data message with position, velocity and time information is presented at the serial interface with NMEA protocol or custom protocol.

Its –165dBm tracking sensitivity extends positioning coverage into place like urban canyons and dense foliage environment where the GPS&GLONASS was not possible before.
The small form factor and low power consumption make the module easy to integrate into portable device like PNDs, mobile phones, cameras and vehicle navigation systems.
