The Soyuz 2.1A converted the flight control system from analog to digital, which allowed launch from fixed platforms. It also allowed big fairings and payloads.
It is currently used for crewed Soyuz and Progress flights to the ISS.

ソユーズ 2.1a は飛行制御系をアナログからデジタルへ転換し、固定式発射台からの打ち上げと、大型フェアリング・大型ペイロードを可能にした。現在は ISS への有人ソユーズとプログレスの飛行に使われている。

The Russian Obzor-R satellite is a planned X-band radar earth observation satellite designed by TsSKB-Progress.

In 2012, the development of the Arkon-2M radar satellite was stopped and instead the development of the Obzor-R was initiated.

The satellite features the BRLK X-band Synthetic Aperture Radar as the imaging instrument with a ground resolution of 500 m.
