"The Lobachevskiy satellite is constructed from aluminum alloys. Solar panels are used for power supply. Gallium arsenide is used for 16-unit devices, such as Lobachevskiy. The devices are assembled with deployable solar panels to orient them toward the Sun and provide the necessary power supply," shared Alexander Khokhlov, head of the Geoscan Group's MKA projects department.
The satellite launch is scheduled for autumn: Lobachevskiy will rise to an altitude of approximately 500 kilometers and fly over Nizhny Novgorod up to three times a day.

Regarding Aist-2T 1&2, Roscosmos has informed its partners that the working launch date is December 30th. Glavkosmos previously announced the target date as December 10th. What is certain is that the launch will not take place on either the 10th or the 30th, and the exact date is unknown. Your opinions are certainly welcome.

If the launch doesn't go on the 30th or 31st, then it would likely be delayed into January, after the several days of the Russian New Year's and Christmas holidays. 🎄

A person who appears to be an insider writes on the NK forum that the two Aist 2T satellites won't be shipped to Vostochny until tomorrow. This person has not posted anything earlier, so I'm not sure how reliable this information is. If it's true, a launch before the end of the year would be iffy.

So the CSTP-4 satellites SCH-619, ANSAT-1 and SM-3.1 are reported to be on this launch, which presumably means they were not on the Jul 25th launch? or the previous ones didn't work and these are copies?  There were satellites cSTP-4.1, 4.2, 4.3 registered
with the UN on the July launch but maybe these are not the SCH, ANSAT and SM sats as was claimed at the time...
any clarification welcome
