Starting from a default ZED-F9P configuration:

  • Enabled survey-in with target accuracy 2.5m (should take no more than 5-10min)
  • Changed UART2 baudrate to 115kbps (this improves the buffer use of the radio links)
  • Activated following RTCM messages
    • 1005: Stationary RTK reference station ARP
    • 1074: GPS MSM4
    • 1084: GLONASS MSM4
    • 1094: GALILEO MSM4
    • 1124: Beidou MSM4
    • 1230: GLONASS code-phase

We have selected this combination of messages because it’s a good tradeoff between performance and required data link:

  • Performance can be improved by using MSM7 messages
  • RF Bandwidth can be improved by eliminated some constellations (e.g. remove Galileo), or increase 1005 to only be sent once every 5 seconds.

Starting from a default ZED-F9P configuration:

  • UART1 and UART2 increased to 115kbps
  • Activated following RTCM messages on UART1, which is connected from the simpleRTK2Blite to the UART2 of simpleRTK2B:
    • 1077: GPS MSM7
    • 1087: GLONASS MSM7
    • 1097: GALILEO MSM7
    • 1127: Beidou MSM7

Starting from a default ZED-F9P configuration:

  • UART1 and UART2 increased to 115kbps
  • Disable NMEA messages in all interfaces, to avoid buffer overflow
  • Enabled on both UART1 and USB:
    • UBX-NAV-RELPOSNED
    • UBX-NAV-PVT
