high sensitivity gps module:-165dBm low power consumption with embedded GPS antenna

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 3327/3329 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 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. Features Ultra high sensitivity: -165dBm22 tracking/66 acquisition-channel receiverWAAS/EGNOS/MSAS/GAGAN supportNMEA  protocols (default speed: 9600bps)Internal back-up battery and 1PPS outputOne serial port and USB port (option)Embedded patch antenna 18.2 x 18.2 x 4.0 mmOperating temperature range: -40 to 85RoHS compliant (Lead-free)Tiny form factor 30mm x20mm x 11.4mmPerformance Specification
