Status: Operational 2013. First Launch: 2013-06-25. Last Launch: 2014-12-26. Number: 2 . Gross mass: 6,600 kg (14,500 lb).

As early as 1989 Russian officials indicated that future civil Earth observation satellites could employ digital electronic transmission techniques in real-time or near-real-time (as used on the Yantar 4KS1 military photographic reconnaissance satellite). This capability was to be realized under the civilian Resurs-Spektr program. The Resurs-Spektr V spacecraft was a modified Yantar 4KS1 satellite and reportedly would produce 3-5 m resolution stereo images. Almaz-class phased-array antennas enabled downlinks via geostationary relay satellites. A second Resurs-Spektr variant, Resurs-Spektr R1, with a side-looking radar, was also proposed. Another possible replacement was an imaging variant of the Kuban spacecraft, which was under development for several years for microgravity research. None of these commercial variants of the Yantar satellite went into production in post-Soviet Russia.

• Resurs-P No. 2 - . Mass: 6,600 kg (14,500 lb). Nation: Russia. Class: Surveillance. Type: Surveillance satellite. Spacecraft Bus: Yantar. Spacecraft: Resurs-Spektr. USAF Sat Cat: 40360 . COSPAR: 2014-087A. Apogee: 475 km (295 mi). Perigee: 463 km (287 mi). Inclination: 97.29 deg. Period: 93.98 min.

  Resurs-P 47KS No. 2 civil imaging spacecraft. The main payload was the Geoton-L1 imager with 0.5m aperture and 38 km swath, 1.0 m panchromatic and 3 to 4m color resolution. Geoton-L1 had 7 passbands and a 216-channel hyperspectral imager. The KShMSA wide field multispectral camera was also part of the Resurs-P primary payload; an AIS ship tracking receiver from OAO RKS and Lomonosov Federal State Univ.'s Nuklon cosmic ray detector were secondary payloads. Nuklon detected cosmic ray nuclei with atomic number 1 to 30 in the 1 to 1000 TeV energy range. Resurs-P went into a 190 km x 428 km initial orbit that was raised to its operational height of 330 km x 471 km on December 29. Sun synchronous orbit; 1150 GMT local time of the descending node.

• Resurs-P No. 3 - . Mass: 6,600 kg (14,500 lb). Nation: Russia. Class: Surveillance. Type: Surveillance satellite. Spacecraft Bus: Yantar. Spacecraft: Resurs-Spektr. USAF Sat Cat: 41386 . COSPAR: 2016-016A. Apogee: 452 km (280 mi). Perigee: 279 km (173 mi). Inclination: 97.30 deg. Third Resurs-P civil remote sensing satellite. The first two satellites in the series were still operating; Resurs-P No. 1 made an orbit adjust burn on Feb 22. The Resurs-P No. 3 spacecraft, however, failed to deploy one of its solar panels..
