Enable GNSS Signals

Supported GNSS Signals

The mosaic-G5 P3 GNSS receiver is capable of receiving most of the GNSS signals from the various frequency bands of each constellation. By default, the module is only configured to utilize signals (marked in green, in the table below) from specific satellites and frequency bands. Whereas, the signals marked in grey are also supported by the module, but each signal needs to be enabled before they can be integrated into the computed Position-Velocity-Time (PVT) solution. Meanwhile, any signals colored in red and struck out are not supported by the mosaic-X5 GNSS receiver; likely due to their proprietary nature, existence outside the module's frequency range, or are experimental/recently implemented.

Enable Additional Signals

Below, are the commands to configure the mosaic-G5 P3 GNSS receiver to track any of the supported GNSS signals. Additionally, users can also configure whether the signals are utilized in the Position-Velocity-Time (PVT) computations or their navigation data is accessed.

  • Signal Tracking

    Command

    Enable Trackings of Specific Signals: setSignalTracking, <list signals>

    Example
    • List Signals: 
      setSignalTracking, GPSL1CA+GPSL1PY+GPSL2PY+GPSL2C+GPSL5+...
    • Track All Signals: 
      setSignalTracking,all

  • Signal Utilization

    Command

    Enable Use of Specific Signals: setSignalUsage, <list signals - PVT>, <list signals - NavData>

    Example
    • List Signals: 
      setSignalUsage, GPSL1CA+GPSL1PY+GPSL2PY+GPSL2C+GPSL5..., GPSL1CA+GPSL1PY+GPSL2PY+GPSL2C+GPSL5...
    • Use All Signals: 
      setSignalUsage, all, all

Tip

Don’t forget to save the configuration to boot, if you want the configuration to persist when you cycle power.

Enable Additional Satellites

Below, are the commands to configure the mosaic-G5 P3 GNSS receiver to utilize additional GNSS satellites that weren't enabled by default. A satellite's tracking and usage must be enabled before their signals can be tracked or utilized.

  • Satellite Tracking

    Command

    Enable Tracking of Specific Satellites: setSatelliteTracking, <list satellites>

    Example
    • List Satellites: 
      setSatelliteTracking, G01+G02+G03+G04+...
    • Track All Satellites: 
      setSatelliteTracking,all

  • Satellite Utilization

    Command

    Enable Use of Specific Satellites: setSatelliteUsage, <list satellites>

    Example
    • List Satellites: 
      setSatelliteUsage, G01+G02+G03+G04+...
    • Use All Satellites: 
      setSatelliteUsage, all

Tip

Don’t forget to save the configuration to boot, if you want the configuration to persist when you cycle power.

Enable GPS L5 Signals

Below, are instructions to configure the mosaic-G5 P3 GNSS receiver to utilize the GPS-L5 band.

Ignore Health Status

Currently, the L5 frequency band from the GPS constellation is pre-operational until a sufficient monitoring capability is established. Therefore, the satellites broadcast an "unhealthy" operational status in their L5 signals and prevent its utilization in PVT computations. These commands disable the health masks to allow the L5 band to be tracked and utilized for PVT computations:

Commands

setHealthMask, Tracking, off
setHealthMask, PVT, off

Tip

Don’t forget to save the configuration to boot, if you want the configuration to persist when you cycle power.

Enable Signals

Below, are commands enable the tracking and use of the signals from the GPS-L5 band in PVT solutions:

Commands

setSignalTracking, +GPSL5
setSignalUsage, +GPSL5, +GPSL5

Tip

Don’t forget to save the configuration to boot, if you want the configuration to persist when you cycle power.

Output Corrections

Below, are the commands for outputting RTK corrections for signals from the GPS-L5 band:

Command

setRTCMv3Formatting, 0, +GPSL5

Warning

The mosaic-G5 P3 GNSS receiver must be configured to receive those GNSS signals (see instructions above); otherwise, it won't have any data to provide the corrections with.

Tip

Don’t forget to save the configuration to boot, if you want the configuration to persist when you cycle power.
