2、FIN端可接有源或无源天线(GPS模块内含滤波和一级放大)采用标准NMEA0183 码支持DGPS协议: WAAS,EGNOS支持AGPS协议,可通过GPRS访问谷歌服务器或SIRF服务器实现AGPS功能(需要运营商的支持)尺寸:16.6mm*12.2mm*2.4mm, 管脚间距: 1.1mmGSD4e WLCSP 模块特性:Fully Integrated, High-sensitivity GPS Engine Performance High sensitivity navigation engine (PVT) tracks as low as -163dBm Highest Perf
3、ormance GPS Engine Extremely low weak signal tracking sensitivity Active Jammer Remover SiRFLocTM AGPS (Autonomous, MS-Based, and MS-Assisted) (Need operator support) SiRFInstantFixTM SGEE/CGEE (Need server support) MEMS Support Smallest footprint and total solution size Highest level of BOM integra
4、tion 48 track verification channels Cold/Warm/Hot Start Time: 35/35/1 sec. At open sky and stationary environments Reacquisition Time: 0.1 second RF Metal Shield for best performance in noisy environments Advantages Integrated high performance LNA, Reduced BOM cost Embedded CGEE (Client Generated Ex
5、tended Ephemeris) that can capture ephemeris data from satellites locally and predicts ephemeris out to 3 days. So if the module was off within 3 days, it could complete positioning process within 2 seconds just like hot start. Removes in-band jammers up to 80 dB-Hz, and Tracks up to 8 CW jammers, s
6、o the module can prevent GPS signal interference when design-in the electrical device with noisy electrical signal interferences such as Laptop, mobile phone, DSC, etc. -160 dBm Acquisition Sensitivity vs. SiRFstarIII -155 dBm -163 dBm Tracking Sensitivity vs. SiRFstarIII -159 dBm Significantly impr
