UWE-3 News 12-03-2015:

Software update of all on-board micro-controllers.

In the beginning of February 2015 we uploaded new software images for all UWE-3 subsystems to the satellite, which comprise in total 3 images on 9 micro-controllers. This software was installed thereafter and is since then successfully operational on UWE-3. The software update targeted major improvements for the attitude control of the satellite, which was the focus of tests right after the update.

The satellite now is back to a preliminary un-operated state (switching between the on-board computers every 4 days) while we process the data and decide on future operation plans. Thanks a lot for your great support! Especially we want to thank: CX8AF, DK3WN, EU1XX, G7GQW, IW0HLG, JA0CAW, JA1GDE, JA5BLZ, JA6PL, JE1CVL, JE9PEL, JO1PTD, LU4EOU, ON4HF, PE0SAT, R4UAB, Rainer Rothe, SP7THR, VK5HI.

UWE-3 Temporary end of operations

Posted on by

UWE-3 BatchToday, 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
