產(chǎn)品描述:SIM68AD L1+L5雙頻GNSS精準(zhǔn)定位模塊
SIM68AD是一款支持航位推算功能的并行多GNSS接收機(jī)。它配備了強(qiáng)大的GNSS核心和6軸IMU。SIM68AD是一款LCC類型的獨立L1+L5雙頻GNSS模塊,采用AIROHA的高靈敏度導(dǎo)航引擎,使客戶能夠以更低的功耗實現(xiàn)行業(yè)高水平的靈敏度、精度和首ci定位時間(TTFF)。
SIM68AD提供同步GPS、GLONASS、北斗、伽利略和QZSS開放服務(wù)L1接收能力,以及GPS、北斗、伽利略和QZSS開放服務(wù)L5接收能力。SIM68AD可以采集和跟蹤多個衛(wèi)星信號的任意組合。SIM68AD將名為EASY(嵌入式輔助系統(tǒng))的*AGPS與成熟的AlwaysLocate技術(shù)相結(jié)合,實現(xiàn)了高性能,完quan符合工業(yè)標(biāo)準(zhǔn)。
