After two weeks in orbit, UWE-4 is in very good shape. The batteries are fully charged, the temperatures of the batteries, the outside panels and the MCU are all lying in the expected range.

UWE-4 battery temperatures and State-of-charge on the first day after launch
It can be seen, that the battery temperatures are slightly rising around 8:45 am, when the downlink of this measurement took place.
After the early orbit phase, we are looking forward to some interesting experiments with the attitude determination sensors and the propulsion system.
Unfortunately, our uplink success rate is very poor, which currently prevents these experiments. In the precursor mission UWE-3, it was found that the reason for this is very likely a substantial noise floor at the used frequency range. For this reason, we filed a request for the change of our radio frequency to 435.600 MHz with IARU, which has already been approved.
Today, we will start the procedure to change the frequency of UWE‑4. So if you want to track UWE-4, please adjust your center frequency accordingly. We already started the procedure to change the frequency on ...
