Detail: GPS Receiver module Skylab SKM53
1.Applications
LBS ( Location Based Service)
PND ( Portable Navigation Device)
Vehicle navigation system
Mobile phone

2.General Description
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 3327 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 and USB 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.
