Thor 1 (formerly: Marcopolo 2 or BSB-R2 ) is a former television satellite that was operated by British Satellite Broadcasting (BSB) and Telenor .
construction
Marcopolo 2 was identical to its sister satellite Marcopolo 1 , which was launched in August 1989.
Operation at BSB
Marcopolo 2 was launched on August 17, 1990, almost a year after its sister satellite Marcopolo 1. After tests it was co-positioned with Marcopolo 1 at 31 ° West . Both satellites broadcast together on the five channels 4, 8, 12, 16 and 20 television programs in the television standard D-MAC, which could be received with 35 cm antennas in the British Isles. In addition, a sister company of BSB marketed the bandwidth for data transmissions that was not used by the television program at D-MAC.
Operation at Telenor
BSB was taken over by competitor Sky Television in late 1991 . Marcopolo 2 stopped broadcasting in early 1992. It was sold to the Norwegian operator Telenor in July 1992 and positioned at 0.8 ° West as Thor 1 , where it worked until January 2002. In November 2002 it was moved to 7.4 degrees West , where it broadcast digital test broadcasts before being placed in cemetery orbit in January 2003 .
