SES Space & Defense together with Planet
Labs successfully demonstrate low-latency LEO space data relay
services via ground system
SES Space & Defense, a wholly-owned subsidiary of SES, today
announced the successful demonstration of the first multi-orbit,
multi-band commercial space relay service in support of the NASA
Communications Services Project (CSP).
To demonstrate data relay services, SES Space & Defense
partnered with Planet Labs (Planet), the leading provider of global
daily Earth data using SES’s O3b mPOWER satellite constellation in
Medium Earth Orbit (MEO) and Planet’s Low Earth Orbit (LEO)
flight-representative terminal.
SES Space & Defense and Planet demonstrated a stable data
link, validating the hardware, data flow and the end-to-end system
performance as well as successfully reduced flight hardware and
services risk. Throughout the testing process, the performance of
Planet’s flight modem correlated with expectations, achieving link
budgets that consistently aligned with predicted results.
The demonstrations support NASA’s Funded Space Act Agreement,
which enables commercial space relay via Geostationary (GEO) C-band
and Medium Earth Orbit (MEO) Ka-band satellites to spacecraft in
Low Earth Orbit (LEO). The initiative allows for NASA’s transition
from the Tracking and Data Relay Satellite System (TDRSS) to
commercial systems for its space relay requirements while helping
create a commercial market for space relay.
In late 2023, SES Space & Defense already demonstrated
Telemetry, Tracking and Commanding (TT&C) relay services
through ground testing of a C-band “always on” channel. This was
accomplished through Planet’s LEO flight-ready C-band terminal and
SES’s C-band GEO global beams.
“With this end-to-end test and demonstration of capabilities, we
were able to successfully showcase a complete data flow through our
LEO Relay System (LRS) service,” said David Fields, President and
CEO, SES Space & Defense. “The data measurement results
validated our multi-band commercial space relay service, set the
stage for the flight demonstration as the next step, and for the
future launch of the operational service offering. We are
exceptionally proud of all involved in developing a multi-orbit,
multi-band space relay for both government and commercial LEO
operators as NASA’s TDRS system retires.”
