OFFSETTIMING SIGNALS AVAILABLEThe maximum permissible measurement error in establishingthe real offset of the station's clock from the master timereference (Ês).The maximum permissible real offset between two clocks atdifferent stations within an agency's network (Ês).The timing signals, derived from the station's clock, which areavailable from the station's frequency and timing subsystem forexternal equipment interfacing (sec).6.1.4 GEOGRAPHICAL & MECHANICAL INFORMATIONLONGITUDELATITUDETYPE OF MOUNTAZIMUTH LIMITATIONSTRACKING SPEED RANGEMAX. TRACKING ACCELERATIONTYPE OF POINTINGPOINTING ACCURACYMIN. TRANSMIT ELEV. ANGLEMIN. RECEIVE ELEV. ANGLETRANSMIT FREQUENCY BANDThe longitude of the earth station's antenna (deg., min., sec.East of the Greenwich Meridian).The latitude of the earth station's antenna (deg., min., sec.North (+) or South (-) of the Equator).Antenna mounting structure configuration, such as azimuthelevation,hour angle-declination, X-Y, etc.Physical constraints on the horizontal movement or pointing ofthe antenna, generally referenced to a specific direction (deg).That range of speeds over which the antenna's beam remainspointed at a target within the specified accuracy (deg/s).The maximum rate at which the antenna's mechanical structurecan alter its tracking speed while remaining pointed at a targetwithin the specified accuracy (deg/s 2 ).The methods by which the antenna's beam can be directedtoward a target such as autotrack, manual, predicts, etc.The nominal precision with which the antenna's beam can bedirected toward a target (deg).The lowest elevation angle usable for transmitting signals to aspacecraft. This limitation can result from either physical orpolicy constraints (deg).The lowest elevation angle usable for receiving signals from aspacecraft. This limitation can result from either physical orpolicy constraints (deg).Those frequency bands and mission Category for which a earthto-spacelink is available on the named antenna (GHz and Cat).CCSDS 411 G-3 6.1-9 May 1997
