Satellites – Tracking (Table)

This table shows information about the satellites that are currently being tracked. To sort the table based on column values, click the header at the top of the column.

Select Satellites / Tracking (Table).

 

The table is organized into tabs for each constellation for ease of viewing or can be viewed together using the ALL tab.

If the background color of a given satellite is red, the satellite is unhealthy. Data from unhealthy satellites is logged but is not used in the position solution.

If the background color of a given satellite on the table is orange, the receiver's RAIM (Receiver Autonomous Integrity Monitoring) algorithm has either detected a problem with the satellite or, if you are tracking SBAS, the corrections indicate there is an integrity problem with the satellite. In either case, the satellite is not used in the position solution.

If the background color of a given satellite on the table is blue, the satellite is tracked, but not yet fully phase locked, so it is not yet available for use in RTK. This typically occurs very briefly when a satellite is first acquired or when the environment is hostile to GNSS.

SV – The numeric identifier of the satellite tracked on the channel.

Type – Indicates if the satellite is GPS, GLONASS, Galileo, BeiDou, QZSS, NavIC, SBAS (WAAS, EGNOS, MSAS), or MSS.

Elev [Deg] – The elevation of the satellite, in degrees above the horizon.

Azim [Deg] – The azimuth (direction) of the satellite, in degrees clockwise from True North.

L1-C/No [dB-Hz] / L2-C/No [dB-Hz] / L5-C/No [dB-Hz] – The signal-to-noise ratio of the satellite on either the L1, L2, or L5 frequency. Scaled to a 1 Hertz bandwidth.

L1 – The signal being tracked in the L1 frequency band (1525 to 1614 MHz for each satellite.

L2 – The signal being tracked in the L2 frequency band (1217 to 1257 MHz) for each satellite.

L5 – The signal being tracked in the L5 frequency band (1164 to 1214 MHz) for each satellite.

Iono – A green, yellow, orange, or red icon indicates the level of ionosphere disturbance that the RTK base station is experiencing on each satellite. The rover receiver shows this same information using the received IonoGuard base messages. All ionospheric data is logged in the standard Trimble T04 raw data files, which can help Trimble Support further diagnose issues. If IonoGuard messages are not being received from the base station, then the circle symbols are replaced by squares, which indicates the rover receiver is in Fallback mode where the rover receiver calculates the ionsophere activity from the base station correction data. Turn the IonoGuard setting on or off on the General page.

IODE (Issue of Data Ephemeris) – The numeric identifier for the latest ephemeris data collected from this satellite.

URA [m] (User Range Accuracy) – The satellite's estimate of the accuracy of its ranging signals, in meters.

Type – Indicates which satellite model or generation is being tracked (if known).
