Resurs-P[1] is a series of Russian commercial Earth observation satellites capable of acquiring high-resolution imagery (resolution up to 1.0 m). The spacecraft is operated by Roscosmos as a replacement of the Resurs-DK No.1 satellite.
The satellite is designed for multi-spectral remote sensing of the Earth's surface aimed at acquiring high-quality visible images in near real-time as well as on-line data delivery via radio link and providing a wide range of consumers with value-added processed data.

Spacecraft
The Resurs-P spacecraft was built by the Russian space company TsSKB Progress in Samara, Russia. It is a modified version of the military reconnaissance satellite Yantar-4KS1 (Terilen).[2] The spacecraft is three-axis stabilized. The design lifetime is no less than five years. The ground location accuracy is 10 metres (33 ft). The maximum daily imaging area is 1,000,000 square kilometres (390,000 sq mi).
Resurs is Russian for "Resource". The letter P stands for prospecting.[3]
