SKYLAB SKG25A1 GPS module 

1.Built in high gain LNA 

2.SMD type with stamp holes 

3.a complete GPS engine module   

The SkyNav SKG25A1 is a complete GPS engine module that features super sensitivity, ultra low power and small form factor. The GPS 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.

It is based on the high performance features of the Atheros AR1511 single-chip architecture, Atheros newest chipset technology. Its –160dBm tracking sensitivity extends positioning coverage into place like urban canyons and dense foliage environment where the GPS 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.
