Mission Control Status Update

Software Update

Since Mission Control is the link between us and the satellites, it is a subsystem with great responsibility. This requires a high technological standard which is the reason the groundstation gets a software update! The new system is easier to handle, clearer and more stable than the old version. For example new diagramms are available or the organisation of the overpasses is improved. The new software is about to be tested. Only the adaption of a few details may delay the change a bit but in a few weeks it will be ready to use. Like every other subsystem, Mission Control also writes their part of the SDR (System Definition Review). New ideas and concepts for tools and trainings came up and are now being discussed. Additionally the batteries on the LNA of the groundstation have been repaired as their quality had deterioated in the previous months.

MOVE-II

During the last month we had expected values regarding uptime which was one and a half hour at best, 15 minutes in average, and a battery temperature of about 0°C. Our turnrate was about 98°/s as measured on July 19th. MOVE-II started to tumble again over the course of a few days because we were not able not detumble it actively. The plan for the next weeks is therefore to slow down the satellite's rotational speed and download data from ADCS and the Payload. In general the communication with MOVE-II works fine, but occasionally we have to deal with interference from other radiosignals.

MOVE-IIb

The status of MOVE-IIb has not changed during the last months. We still have not received data with our ground station in Garching. Although we have some ideas why it is not working, it takes time for us to prove these theories. A part of the team works on solving this problem, even within the framework of a seminar paper. They collect information and get in touch with other ground stations.
