Skylab GPS receiver module SKG*5A1

1. Introduction
The Skylab SKG*5A1 is a complete GPS module that features super sensitivity, ultra low power and small form factor. The GPS signal is applied to the antenna 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 **0dBm 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
