Specifications

The Skylab 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 3329 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.
