Enable the GPS-L5 Band

The RTK mosaic-X5 is capable of receiving signals from the GPS L5 frequency band and outputting RTK corrections for the L5 band. However, since the GPS L5 service is currently pre-operational and marked as "unhealthy", it takes some extra configuration steps to enable the L5 frequency band and corrections.

L5 Signal Reception

Below, are instructions to enable the RTK mosaic-X5 to receive GNSS signals from the GPS L5 frequency band.

Web Interface

Admin > Expert Control > Control Panel > Navigation > Receiver Operation > Masks - Set "Discard unhealthy satellites" to off for both "Tracking" and "PVT"

  • setHealthMask, PVT, off
  • setSignalTracking, +GPSL5
  • setSignalUsage, +GPSL5, +GPSL5

Output L5 Corrections

Below, are instructions for outputting RTK corrections for the GPS L5 frequency band, from the RTK mosaic-X5.

Warning

The RTK mosaic-X5 must be configured to receive those GNSS signals (see instructions above); otherwise, it won't have any data to provide the corrections with.

Web Interface

From the drop-down menu of the Corrections tab of the web interface, select Corrections > Corrections Output to bring up the corrections output settings. On this page, locate the Advanced Settings menu, where users can define the data intervals and formatting. Clicking on this will prompt a security dialog box to pop up, click the Proceed button to make changes to these settings. RTK corrections for the GPS L5 frequency band are only available in the RTCMv3 messages; therefore, users will need to select the RTCMv3 tab.
