avl gps SKG25A1 Skylab gps module
high sensitivity gps module:-160dBm
low power consumption
stable performance both static state and movement
The Skylab SKG25A1 is a complete GPS module with 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.
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
