| 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 每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.. |
