The LituanicaSAT-1 team have provided a further update on their CubeSat which was deployed from the International Space Station (ISS) on February 28.
As most of you have already noticed, since May 12 the satellite has been set up to nominal operational mode permanently with noticeable 9k6 baud packet telemetry on 437.544 MHz every 30s. However next day on May 13 a telemetry report from W7KKE has shown that a latchup has been detected on 3.3 V1 EPS channel.
This channel is providing power for CW FM beacon and photo camera. Furthermore following reports from W7KKE and LU4EOU have shown that an OBC reset had occurred on Tuesday, 13 May 2014, 16:27 UT and on 14 May 2014, 01:47 UT (9 h 20 min since first reset).
The reason for these resets and latchup are still unknown but currently all systems are working properly. Due to that we prefer to leave the satellite in safe mode during passes outside the range of our ground station in Vilnius.
