RESHETNEV company developed a new satellites SADM (Solar Array Drive Mechanism).
While being compact and light, the new type of drive mechanism for small satellites has improved performance.
The drive mass is about 800 grams, which is approximately six times lighter than drives of similar performance. This new RESHETNEV development has turned out to be much more durable than was initially required by the specification: during the tests, 40 thousand revolutions were made instead of the intended 10 thousand.
The first model of the new drive mechanism has almost no differences from the flight model mounted on the experimental MARATHON satellite. Such partially adapted devices are planned to be used in mass produced MARATHON satellites.
