The OPS-SAT Flight Control Team is currently in the process of uploading an update to the on-board software.
This was done in reaction to the discovery of a safety bug in the operation of the S-band transmitter.
The update will ensure safe operations of the transmitter during S-band passes with ESOC.
All power and attitude parameters of the spacecraft are nominal.
No payloads have been turned on yet, once the S-band link is brought into safe service after the update, payload
commissioning will start which is on schedule and planned for late January/early February.
Kind regards,
OPS-SAT FCT
The ESOC Flight Control Team wants to say a massive thank you to the Radio Amateur community!
The observations sent to us have been extremely useful in the early operations so far.
Due to limited Telemetry, all beacon observations are still more than welcome and are very useful to us.
We will continue to provide updates as operations progress.
Various sources and doppler observations indicate that object with NORAD ID 44878 (2019-092F) is OPS-SAT.
The updated tle can be found at: https://opssat1.esoc.esa.int/tle.txt
A new TLE was handed over to us by the ESOC Flight Dynamics taking into account the 24 hour shift: https://opssat1.esoc.esa.int/tle.txt
A final TLE will be provided by Arianespace after separation of the spacecraft.
A new launch date has been communicated by Arianespace, 18th of December at 08:54:20 UTC.
Press release attached.
Calling all radio amateurs! ESA is challenging anyone with amateur radio equipment to catch the first signals from OPS-SAT, ESA’s brand new space software laboratory.
On 17 December 2019, OPS-SAT will be launched into low-Earth orbit on a Soyuz rocket from Kourou, French Guiana, together with ESA’s Cheops exoplanet-hunter .
Once launched, the satellite will deploy its solar panels and ultra-high frequency antenna, and then start to send signals back home.
Could you be the first on Earth to catch them? ESA’s mission control team in Darmstadt are asking for your help to find the fledgling CubeSat.

The details¶
Lift-off is scheduled for 08:54:20 UTC on 17 December 2019. Deployment will begin 15044.6 seconds later (T+15044.6 seconds), expected to be at 13:05:04 UTC. OPS-SAT will begin transmitting 15 minutes after satellite deployment and after ultra-high frequency (UHF) antenna and solar array deployment have been confirmed. The first two passes over Europe are expected on the same evening.
To track OPS-SAT, a preliminary launch TLE is available here: https://opssat1.esoc.esa.int/tle.txt
Setup your own mission control system¶
The OPS-SAT flight control team has developed open source software which allows anyone to receive the UHF beacon of OPS-SAT and decode it. A set of ‘GnuRadio’ applications have been developed and are available here . You can use a wide range of ‘software-defined radios’ (SDR’s) supported by GNURadio to receive the UHF signal. The application toolkit consists of a receiver and demodulator flowgraph as well as a GUI telemetry desktop, parsing packets coming from space in real-time. The repository is located at: https://github.com/esa/gr-opssat
