GPS ONE Xtra in SL8090

Legacy Legacy AirPrime modules
2

Hi,

Please find my understanding,

  • Module use the downloaded XTRA data for position fix only, it will not upload Almanac nor Ephemeris data back to Xtra server after getting fix

  • The Xtra data is valid normally for few days but it won’t be stored in internal memory so it become invalid in your test.
    We need to manually start the download, via AT!GPSXTRAINITDNLD, every time after power up or enable auto download feature with AT!GPSXTRADATAENABLE)

Thx
