The Resurs-P series of Russian civil Earth observation satellites is the successor of the Resurs-DK 1 satellite. It is used by commercial customers as well as Russia’s Ministries of Agriculture and Fishing, Meteorology, Transportation, Emergencies, Natural Resources and Defence and capable of acquiring high-resolution imagery (resolution up to 1.0 m).

Comparing the Resurs-P 4 and P 5 pair to the three of its predecessors (Resurs-P 1, 2, 3), significant advancements were made. First, in response to user demand, Roskosmos installed a second high-resolution camera, ShMSA-VR, in place of the wide-angle ShMSA-SR, which had a resolution of between 60 and 120 meters. The dual high-resolution lens system on the new satellites almost doubles the amount of Earth's surface that the satellite can image. Common avionics accommodate the improved multi-spectral system.

Furthermore, RKTs Progress subcontracted the development of its new version to RKS Corporation in order to boost the downlink rates for imaging from the satellite to the ground to 600 megabits per second, following technical issues with the data-transmission system on two prior satellites.

Additionally, Roskosmos removed the BRK AIS ship identification system hitchhiker payload and the Nuklon research instrument from the satellite's payload package.

Resurs-P 4 was successfully launched on a on 31 March 2024.
