Russian Earth observation
|
|
Resurs-DK No.1, often incorrectly translated as 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).
Resurs is Russian for "Resource". The letters DK are the initials of Dmitry Kozlov, chief designer of the first satellite of the Yantar-2K class.
Made by Vavilov State Optical Institute, Russia. [1]
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.
