LEO Vantage 2

LEO Vantage 2 [UTIAS]

Telesat ordered in April 2016 two prototype Ka-band HTS (High Throughput Satellite) communication satellites, yet unnamed, as part of a test and validation phase for an advanced, global LEO satellite constellation that Telesat is developing.

Telesat will test and demonstrate two distinct spacecraft in LEO, a key step in optimizing the design and performance of Telesat’s contemplated LEO constellation. One of the satellite will be built by Space Systems Loral (SSL) of Palo Alto, California, with UTIAS Space Flight Laboratory (SFL) as subcontractor for providing the bus, and the other by Surrey Satellite Technology Limited (SSTL).

The bus of the SSL satellite was subcontracted to UTIAS SFL, who provided their DAUNTLESS platform.

The satellite was launched on 28 November 2017 as a copassenger on a Soyuz-2-1b Fregat rocket, but was lost due to an upper stage problem.
