The table of the Terrestrial Engine RT Residual History view displays for each station (identified by the Station Name) and target (identified by its Target Name) the distance, lateral, and vertical residuals, and its current Horizontal DOP value. If one of the residuals or the DOP exceeds the threshold specified in the Setup Alarm Thresholds and HDOP Thresholds categories of module properties, an alarm is issued.
All entries are derived from the TerrestrialEngineRT_StationSetupHistory table of the technical database.
