Skylab GPS Module SKM53 with Embedded Patch GPS Antenna chipset MT3339
1.Introduction:
The SkyNav SKM53 Series with embedded GPS antenna enables high performance navigation in the most stringent applications and solid fix even in harsh GPS visibility environments.
It is based on the high performance features of the MediaTek 3339 single-chip architecture, Its –165dBm tracking sensitivity extends positioning coverage into place like urban canyons and dense foliage environment where the GPS was not possible before. The 6-pin UART connector design is the easiest and convenient solution to be embedded in a portable device and receiver like PND, GPS mouse, car holder, personal locator, speed camera detector and vehicle locator.
2. Features:
Ultra high sensitivity: -165dBm
22 tracking/66 acquisition-channel receiver
WAAS/EGNOS/MSAS/GAGAN support
NMEA protocols (default speed: 9600bps)
Embedded patch antenna 18.4 x 18.4 x 4.0 mm
