2.9. AT+QGPSXTRADATA    Inject a gpsOneXTRA Data File 
 
This  command  can  be  used  to  inject  a  gpsOneXTRA  assistance  data  file  to  GNSS  engine.  Before 
operating this command, customers must enable gpsOneXTRA, store the valid gpsOneXTRA data file 
into RAM or UFS (RAM is recommended) of the mudule and inject gpsOneXTRA time to GNSS engine.
