Educational mission with digipeater and testing gamma-ray burst sensor. |
| Description |
Support the HAM radio community with the possibility of use this satellite for their activities. The satellite will have a digipeater functionality. CW beacon with callsign, telemetry and selectable special message. All the data transmitted by the satellite will be open for public use and will be published on the internet. The second goal is to test a special sensor developed by PhD students from Hungary and Japan which will be able to detect gamma ray bursts. These bursts are the signals that the gravitational waves run through the earths atmosphere. This experiment can give us the possibility to estimate the coordinates in space where the gravitational waves came from. |
| Results |
Initial rotation rates were over 18 degrees per second, but slowing down with only passive attitude control. |
