The Monitor/Skyplot command allows you to review local position and quality of data.
- Quality: Under the QUALITY tab you monitor the status and number of satellites. You can also see values for horizontal and vertical RMS values, as well as HDOP, VDOP, PDOP, TDOP and GDOP values. Some instruments refer to RMS values as CEP and SEP. For the CSI DGPS and the Sokkia Axis 3 receivers using OmniStar, the BER value will be shown in order to give indication of the strength of corrections received. When set to CSI DGPS, the age of corrections is also displayed. The number of satellites (SATS) is shown.

The Status is shown as either:
AUTONOMOUS: No radio communication between base and rover.
DGPS: Corrections from a differental sources such as WAAS or SBAS.
FLOAT: Communication has been established, but ambiguities have not been resolved.
FIXED: Position has been resolved.
- Position: Under the POSITION tab you see the current position given in latitude, longitude, ellipsoid elevation, geoid separation, and orthometric elevation. You will also see the local grid coordinates here.

- SATView: Under the SATView tab, the spatial orientation of the satellite constellation is shown. Click on any satellite number to see details. You can also toggle satellites on and off if supported by the GPS.

- SATInfo: This tab shows information on Satellites.
- PRN is the satellite reference numbers. * indicates satallite in use for position calculation.
- AZI: is the satellite azimuth.
- ELV: is the satellite elevation above the horizon.
- S/N: is the signal to noise ratio indicating quality of satellite signal.

- Ref: The REF tab to the right of SAT Info appears with most GPS configurations (not with GPS Simulation). The REF tab will show the base station information stored to the reference file, which is created during base configuration. The Magellan/Ashtech GPS, for example, will show the distance from rover to base. The base coordinates can also be stored by pressing the Store button.
You simply enter a point number and description, and the precise base coordinates are stored in north, east and elevation, according to the localization file settings. Then the base coordinate point can be used for total station work as a setup or backsight. If a base position of 0,0,0 is detected, representing in invalid base setup, the Store button will be grayed out.

With Leica GPS, it also shows the status of the radio signal in the middle two lines. If the radio signal is interrupted, a “No Radio” message will appear. The Utilities button associated with the Leica GPS configuration takes you straight to the radio settings, including cell modem configuration.
