EMS Technologies, Inc.
recently delivered a spare high-gain antenna for the International Space
Station.
This space-to-ground antenna, capable of data rates of up to
75 Mbps, is used for all high data-rate transmissions and receptions to the
International Space Station (ISS).
Its 74-in diameter parabolic cassegrain
reflector carries multi-channel video as well as high-speed scientific data.
Using sophisticated materials (titanium, carbon fiber and kevlar), the
gimbaled Ku-band antenna automatically tracks NASA’s Tracking and Data Relay
Satellite System.
Its functionality complements the gimbaled S-band antennas,
a criticality-1 system used for low data-rate telecommunications, telemetry &
command (TT&C).
Two S-band antennas and one Ku-band antenna have already been
launched, delivered and installed on board the International Space Station,
ensuring complete bi-directional space-to-ground-to-space communications
coverage.
This delivery is the final shipment of communications antennas for the
ISS. A total of three S-band (two on-orbit and one ground spare) and three Ku-
band antennas (one on-orbit and two ground spares) have now been delivered
from EMS Technologies’ Space & Technology Group in Montreal.
