The Chibis-M microsatellite, also known as RS-39 (RadioSputnik 39), was jettisoned from the Progress M-13M cargo spacecraft Tuesday evening (UTC). The satellite is designed to study atmospheric phenomena such as Terrestrial Gamma Ray Flashes (TGFs) associated with lightning. RS-39 has CW beacons on 435.315 and 435.215 MHz and amateurs are asked to submit reception reports via email to the Space Research Institute of the Russian Academy of Sciences at [email protected]. Each report will be acknowledged with a special QSL. The CW telemetry format is available here. Telemetry decoding software written by Mike Rupprecht, DK3WN, can be downloaded here.
