產(chǎn)品描述
車規(guī)級(jí)GPS模塊SKG12Q簡(jiǎn)介
SKG12Q是SKYLAB針對(duì)汽車前裝市場(chǎng)推出的一款車規(guī)級(jí)GNSS(BDS、GPS、GLONASS、GALIEO、QZSS和SBAS)定位模塊。具有高靈敏度和高可靠性,內(nèi)部閃存可以進(jìn)行程序升級(jí)以支持不同場(chǎng)景應(yīng)用。擁有額外的前置LNA用于優(yōu)化RF性能,并且包含前置SAW濾波器可提高抗干擾性能,即使在弱信號(hào)依然有較高的定位精度和較短的定位時(shí)間。
SKG12Q模塊使用符合AEC-Q100標(biāo)準(zhǔn)的芯片,生產(chǎn)流程符合ISO/TS16949認(rèn)證要求。模塊的質(zhì)量測(cè)試均符合ISO16750標(biāo)準(zhǔn)中“道路車輛-環(huán)境條件以及電氣電子設(shè)備測(cè)試標(biāo)準(zhǔn)”的相關(guān)規(guī)定。
