Location and capabilities
The Yatharagga Satellite Station is located in Western Australia, 29.2º south of the equator, 250 meters above sea level and approximately 400 kilometers northwest of Perth. From this advantageous position, the station provides orbit raising and daily pass support to both polar and low-earth orbiter (LEO) missions. The site’s support capabilities also include geostationary (GEO) orbit raising operations, first acquisition of the launch vehicle and spacecraft telemetry at orbit insertion/deployment.
The Yatharagga Satellite Station, together with the Dongara Australia Satellite Station, is part of the Universal Space Network’s GEO orbit raising network which also includes the Santiago Satellite Station and the South Point Hawaii Satellite Station.
Antennas and basebands
The Yatharagga Satellite Station is owned and maintained by SSC’s
Australia-based company SSC Space Australia. The station is operated from the SSC main station in northern Sweden at the Esrange Space Center.
The Yatharagga Satellite Station primarily serves government agencies and commercial customers. It includes one 13.56-meter S-band antenna with capabilities for Telemetry Tracking & Command (TT&C) and data downlink services with the capability of providing fast field upgrade with X-band or Ka-band reception capability for future customer needs.
The station is well equipped with a very high hot redundancy equipment level and outstanding S-band receive and transmit performance. The entire station, including the antenna system, is fully supported by a UPS power supply system and will therefore not suffer from any power outages during critical supports. The ground station also includes an operational building which houses system electronics and frequency conversion equipment. Space is also available on site to host customer-owned base band equipment.
At the Yatharagga Satellite Station, a new power plant has been established which includes a 300 KVA backup generator and a 125 KVA UPS system. The power system also allows uninterrupted transfer between mains and backup generator (and back to mains) during planned transfers. This power plant supplies power to both the Yatharagga Satellite Station and the Dongara Australia Satellite Station.
The Yatharagga Satellite Station is situated in the Yaragadee district of Western Australia. The temperature is generally warm averaging 27-29ºC with a variation of +/-3ºC year-round. Summers are warm, but not hot. Rainfall ranges from
6 or 7 mm per month from November through February to 70 or 80 mm per month from May through August.
