17*22mm gps module mtk3329 SKG17

High sensitivity MT3329 gps module: -165dBm Built in high gain LNA Low power consumption short&open antenna protection

The Skylab SKG17 base on MT3329 chips is a complete 17*22mm GPS 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.

Its -165dBm 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.
