Tanum Teleport is a well-visible landmark for anyone traveling on the E6 in northern Bohuslän. The big white satellite dishes are well visible. The teleport is located a few kilometers south of Tanumshede in the municipality of Tanum. The largest antennas have a diameter of 30 and 32 meters, respectively.

The plant, a ground station mainly used for transmission of telephony, data and television traffic to other continents via satellites in the INTELSAT system, was initiated in 1971. The first satellite phone call over the Atlantic via satellite was sent in conjunction with the opening ceremony on 18 December.

Initially, the facility was called Nordisk Telesatellitstation and was jointly owned by telecommunications administrations in Denmark, Finland, Norway and Sweden. Later, Telia and Sonera (Finland) became sole owners.

The facility acted as a point of intersection when the forerunner of the Internet became international for the first time in the early 1970s. It took place on June 15, 1973 when an existing satellite link between SDAC in Virginia USA and NORSAR in Norway is connected to Arpanet. The connection was used for data transfer in a joint research project between Norway and the United States to detect earthquakes and nuclear explosions and had a transmission capacity of 2.4 kbps.

During the period of the 1980's / 90's, over 30 people worked there around the clock and the facility handled a large part of the Nordic telecommunications and data traffic to overseas countries. For several years, a reference station was also provided and synchronized for two of the INTELSAT system's digital platforms, and participated in the development of these.

During the 1990s, competition increased from optical fiber cables, which were laid on the ocean floors between continents. The competition made the operation of Tanum Telport stagnant and in connection with Telia taking a strategic decision to discontinue all its satellite operations in the early 2000s, Tanum's Teleport was closed in 2002.

The plant was purchased by a local contractor. Some equipment has been sold, but the antennas still remain. Today the company is called Corporate Port.

Two of the former employees at the station, some time after the closure, operated a company that used one of the Internet communications antennas for an African telecom operator.
