	SWEPOS station in Vänersborg.		Complete stations GPS data from SWEPOS are registered continuously from 21 reference stations all over the country, from Kiruna (Esrange) in the north to Hässleholm in the south. To achieve redundancy and secure data access, we have equipped each reference station with two parallel systems. The pillars are made of concrete and are placed on solid bedrock, often at high altitudes, where the obstacles are in low elevations (free line of sight to the satellites).
	The pillars are heated to a constant temperature (15°C) to minimize expansions due to temperature changes. All reference stations use Dorne Margolin antennas with hemispherical domes. Power supply is also built to handle failures like power outages. The power supplies consist of batteries and AC/DC-DC/AC converters with a capacity of 48 hours. Almost all equipment can be remotely controlled which helps in managing and locating some problems. A local air conditioning system and radiator keep the temperature constant in the SWEPOS stations. Both are connected to a regulator, automatically controlling the activity, which can also be adjusted from the Control Centre over the Intranet. At least once per year, we make a visit to all reference stations for service, e.g. firmware upgrade, installation of new equipment and battery checks. Simplified stations These have a lower status then Complete stations. Antennas are mounted on buildings and the equipment, as reciever and tele comunication are placed indoor the house. Most common are schools and official buildings. The power supply and control of temperature are not so good as for the Complete ones. These are used for the Network RTK service.
