Resurs-DK No.1, also called Resurs-DK1, is a commercial Earth observation satellite capable of transmitting high-resolution imagery (up to 0.9 m) to the ground stations as it passes overhead. The spacecraft is operated by NTs OMZ, the Russian Research Center for Earth Operative Monitoring.
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.
The Russian space tracking service, ASPOS OKP, reported that the spacecraft's onboard systems and attitude control had been terminated in February 2016. Tracking of the satellite was discontinued on 1 March.
The Resurs-DK 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). The spacecraft is three-axis stabilized. The design lifetime is no less than three years, with an expected lifetime of five years. Ground location accuracy is 100 metres (330 ft). Onboard storage is 768 gigabits. Data link speed to the ground station is 300 Mbit/s. Maximum daily productivity is 1,000,000 square kilometres (390,000 sq mi).
Made by Vavilov State Optical Institute, Russia. 
It is not possible to represent an image in true-color because there is no blue band (0.4 - 0.5 μm). However, it is possible to combine red, green and near IR in such way that the appearance of the displayed image resembles a visible colour photograph, i.e. vegetation in green, water in blue, soil in brown. This is not always possible because two similarly coloured objects can have completely different reactions to near IR light.
Green, red and near IR are typically combined to make a traditional false color composite where the near IR is displayed in red, the red is displayed in green, and the green is displayed in blue. This combination is favoured by scientists because near IR is useful for detection of numerous vegetation types. Vegetation appear as redtones, the brighter the red, the healthier the vegetation. Soils with no or sparse vegetation range from white (sand, salt) to greens or browns depending on moisture and organic matter content. Water appears blue, clear water is dark blue to black while shallow waters or waters with high sediment concentrations are lighter blue. Urban areas will appear blue towards gray. Clouds and snow are white.
Unit features 4 TDI (Time Delay and Integration) sensor arrays, one panchromatic and three multispectral. Each sensor array is composed of 36 "Kruiz" CCD chips. Effective length of the single array is about 36000 pixels. Arrays are grouped in 3 separated lines:
This separation is causing a time delay of the colour images combined from green, red and near IR, so fast-moving objects are shown in triplets. Moving object speed and direction can be calculated. All 4 arrays can work simultaneously, so it is possible to combine panchromatic and 3 multispectral images in one pansharpened color composite.
The system use 10-bit analog-to-digital converters

PAMELA Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics is an attached module built by Italian researchers with international partners. Its purpose is basic physics research of primary cosmic rays.
The satellite was initially placed in a 355 by 573 kilometres (221 mi × 356 mi) orbit in 2006. On 10 September 2010, its orbit was circularised to 567 by 573 kilometres (352 mi × 356 mi), with an inclination of 69.9 degrees.
