Telesat and EMS Satellite Networks to deploy DVB-RCS hub using DVB-S2 on
Anik F2

OTTAWA, ON, March 24, 2005 - Telesat, one of the world's leading satellite
operators, and EMS Satellite Networks, a division of EMS Technologies Inc.,
announced today that they have been selected by the Canadian Space Agency
("CSA") to deploy a DVB-RCS system using DVB-S2 technology on the Ka-band
payload of Telesat's Anik F2 satellite - one of the largest commercial
communications satellites ever launched.

Telesat and EMS will demonstrate a unique combination of technologies as
part of this project. The system will be operated from Telesat's Vancouver
gateway over three of Anik F2's Ka-band spot beams covering northern Canada.
In addition to the DVB-S2 component of the demonstration, the system will
support adaptive carrier rates, allowing remote terminals to switch between
carriers with different rates to adjust for signal fade conditions at
Ka-band. EMS will also demonstrate its latest embedded acceleration and
compression technologies.

Telesat and EMS hope to build on this effort to offer commercial services to
northern communities utilizing this state-of-the-art technology in 2006.

"Telesat looks forward to experimenting with DVB-RCS, which is a key
international standard for broadband satellite services," said Paul Bush,
Vice President, Broadcasting and Corporate Development. "As well, this
project will give us an opportunity to test a number of government
applications as a precursor to possible follow-on commercial services."

"EMS has been at the forefront of open standard, two-way satellite
communications since the early 1990's," said Don Osborne, Senior Vice
President and General Manager, EMS Satellite Networks. "This initiative
complements ongoing internal research and development efforts to maintain
our technology leadership in this market."
