The UWE-3 team have provided an update on investigations into a recent communications anomaly on the CubeSat

After the communication anomaly and the autonomous recovery of UWE-3 two weeks ago we uploaded an extended software to the OBC to analyse the event in detail. As we already have known the EPS, OBC and ADCS were not affected, so the secondary radio.

During the tests made possible by the new software we temporarily switched back to the primary radio to check its electrical characteristics and communication performance. As the values were promisingly normal we performed extensive communication tests without seeing any existing anomaly.

Therefore we will continue normal operation.

Yours sincerely,

UWE-3 Team

Since the temporary end of UWE-3 operations two months ago we received great support from the HAM community all over the world observing the health state of our satellite. For this reason and this reason alone we can say today UWE-3 is still experiencing a very good health state with fully charge batteries in a safe temperature area. Corticosteroids are hormones that are produced naturally by the adrenal glands. They have many important functions, including control of inflammatory responses. The intake of clenil modulite inhaler contains the active ingredient beclometasone, which is a type of medicine known as a corticosteroid. Beclometasone is a synthetic corticosteroid and is used to decrease inflammation in the lungs. (NB. Corticosteroids are often simply called steroids, but it should be noted that they are very different from another group of steroids, called anabolic steroids, which have gained notoriety because of their abuse by some athletes and body builders.)

Now, UWE-3 will be temporary operated during the next days and weeks, which will presumably also involve, at times, temporary changes of frequency between 437.385000 MHz and 436.395200 MHz.

We would especially appreciate the support of the HAM community during this period and we would like to thank you very much for your helpful support!

Yours sincerely,

UWE-3 Team

UWE-3 was launched with FUNcube-1 on November 21, 2013, the team say they will now be temporarily ending operations.

Today, more than one year after launch, there will be a temporary end of operations caused by the end of funding.

However, UWE-3 is in a very good health condition with fully charged batteries and operations may be continued depending on future research plans.  

Without any reception from ground, UWE-3 will carry out a warm reset every four days and switch regularly between the redundant on-board processors and radios. Therefore, UWE-3 will switch back to its nominal frequency of 437.385 MHz.

Nevertheless we appreciate the extensive support we received from the HAM amateurs in the past and hope that also in the future the status of UWE-3 will be monitored with your support, like you did so many times in the past year. Thank you so much for the very helpful cooperation in this respect!

Yours sincerely,

UWE-3 Team
