Description:

• TELSTAR 18V (Telstar 18 Vantage / APStar 5C) is a geostationary communication satellite in the Telstar series of the Canadian satellite communications company Telesat. The satellite is equipped with C and Ku-band transponders and operate from 138° East. At 7,060 kilograms (15,560 lb), it is the second-heaviest communication satellite ever launched, weighing slightly less than its sibling TELSTAR 19V.

Mission details:

• Telesat Canada has another massive (7070 kg launch mass) C/Ku-band Maxar/SSL-1300 communications satellite in orbit: Telstar 18 Vantage.
  Much of the mass is propellant which will be used to reach GEO following is launch, to an 18000 km apogee subsynchronous transfer orbit by a Block 5 Falcon 9, repeating the mission profile of Telstar 19 Vantage in July.
• APT (Asia Pacific Telecom) has leased some of the capacity on the satellite, and refers to the satellite as Apstar 5C.
• The Falcon 9 first stage, B1049, landed safely on the droneship ′Of Course I Still Love You′. The second stage remains in transfer orbit.
• Telstar 18V made its first apogee raising burn at 0800 UTC Sep 11, to 292 x 20475 km x 27 deg. By Sep 18 the orbit was 12083 x 35752 km x 7.3 deg.
