I’m working on development of GPS asset tracker with BG96.
at+qgpsloc command, it collects position information and post to server. Basically it works well.
Now I’m curious if it uses QZSS or not.
If I enable Beidou by gnssconfig command like
AT+QGPSCFG="gnssconfig", 1, does it already using QZSS also for positioning?
Or, do I need to do something special such as upload a specific firmware to enable QZSS for positioning?
BG96 GNSS AT commands manual and
BG96 GNSS Application Note, I could not find description about how to enable QZSS for positioning.
Just for NMEA sentences, I found that QZSS sentences will be output along with Beidou sentences.
Thanks for the answer.
I thought that the enable/disable of NMEA sentences is just about if the module output sentences when requested by
AT+QGPSGNMEA command, which is independent to
AT+QGPSCFG="gnssconfig" controlling which constellation to be used as a whole system.
Let me change my question.
Does BG96 use QZSS to get position by following commands?:
AT+QGPSCFG="gnssconfig",1 // GLONASS ON/BeiDou ON/Galileo ON
AT+QGPS=1 // Turn on GNSS.
~~ wait for fix ~~
AT+QGPSLOC? // Obtain positioning information.
Could you let me know the confirmation status?
I suppose whenever GPS is enabled, QZSS is also enabled.
However you need to check PRN number stated in the NMEA messages to see if any QZSS satellites have been used.
Thanks, let me confirm.
