 1994-079A

---

Orion 1 was a Eurostar 2000 class satellite built for Orion Network Systems Inc, Rockville MD by British Aerospace Space Systems Ltd. It provided commercial transatlantic communication services.

This was the first comsat to use a very high apogee supersynchronous transfer. LEOP control was from MMS SCC,Stevenage. ORION had a ground station at Mt Jackson, Virginia. The satellite was reportedly registered with the UN by the UK (although the document does not appear to be in the public archive). It was also registered by the US in ST/SG/SER.E/288.

In Nov 1999 Loral Orion renamed the satellite Telstar 11. Loral Orion then became Loral Skynet.
