The GPS receiver is installed in the Kiruna ground station, which is at Salmijärvi, 38 km east of Kiruna in northern Sweden.
This was the first installation of a set of 5 TurboRogues ordered by ESOC. After a period of testing in ESOC the receiver was deployed to the station on the 8th of July 1993.
The receiver is in a building several metres away from the main equipment room of the station. From this building the distance to the monument is shorter. The geodetic monument was constructed following the model defined for the other ESA sites. It is on the top of a slope surrounded by trees.
The first receiver in operation was a TurboRogue SNR-8100 and was updated to the AOA ACT technology in September 2000.
The receiver is connected to a 5 MHz output of the station timing system, a Cesium manufactured by OSCILLOQUARTZ.
The antenna installation and monumentation are similar to the ones of the other ESA stations.
The communications were initially performed with a Telebit T2500 directly connected to the TurboRogue. It was replaced by a PAD running on a permanent line that improved the reliability and reduced the operation cost. A remote PC is being used (like in the other ESA stations) to improve the performance provided by the receiver in terms of remote control and data buffering.
The Station Information Form (SIF) summarises the characteristics and development of the GPS site. The last version and more information are available from the IGS Central Bureau
