Earth remote sensing (ERS)
In accordance with the definition of the Remote Sensing (RS) – it’s a data about Earth received from the space, by using capabilities of electro-magnet waves emitted, reflected, absorbed or scattered by the objects of sensing.
The whole surface of Earth, including elements of land, water, atmosphere, natural phenomena, anthropogenic factors and formations, are the objects of sensing of Remote Sensing respectively.
National Space Facilities Control And Test Center (NSFCTC) is the only structure in Ukraine, that provides all variety of actions in sphere of Remote Sensing, including exploitation of Remote Sensing framework generally or its separate elements: storing, analyzing, interpretation (decrypting) and distribution Remote Sensing data.
Moreover, NCSFCT is officially recognized as a national operator of Remote Sensing systems.
In structure NSFCTC – there are Center Of Special Information Reception and Processing (CSIRP) and Navigation Field Control (NFC) (located in Dunaevtsi city, Khmelnytsky region) with several active data receiving stations in range from 1.7GHz to 8.2GHz; stations of coordination and reception of telemetric data.

NSFCTC specialists has been providing full-scale exploitation of all national RS satellites beginning with the first ukrainian satellite “Sich-1” which was launched in 1994. Particularly NCSFCT specialists were involved within the framework of Ground Control Complex (GCC) and Ground Information Complex (GIC).

In nearest future the launch of perspective national satellites with resolution of 7,8m and 2,5m is planed. Total technical modernization and re-equipment of GCC and GIC as well appropriate training of NSFCTC personnel are going to be done in order to meet the requirements of listed above space systems.

Ground Control Complex (GCC) is a complex of territorially spread radio engineering, optoelectronic and electronic computing ground facilities, which are used to control one or few spacecrafts of specific space system.
The GCC facilities solve the following tasks:
Spacecraft Mission Control Center (SMCC) – is an organizational and technical complex that is intended for control of spacecraft that are part of the space system.
The main questions that are solved by SMCC during the stage of preparation of the spacecraft for the launch are following:
Tasks of SMCC during the regular operation stage are:
Works on the redeployment of the SMCC to CSIRP and NFC were initiated in 2015.
Land Station SKTRL-M1
Modernized land compatible command-telemetry radio line station is intended to:
Universal Ground Information Reception Station (UGIRS-8.2). It’s a reception station of high resolution remote sensing data. It provides reception, visualization, and the X-range information extraction from “Sich” and “EgyptSat-1” – type spacecraft.
ERS Information Reception Station (ERS IRS-137). Station is intended to receive, register and pre-process the information that was obtained from meteorological and natural-resource artificial satellites of the Earth in metric range of waves with the low resolution. It provides receiving of the APT-information from the “Sich”, “NOAA”, “Resurs-04” – type spacecrafts. For today the receiving is being carried out from “NOAA” – type spacecraft (AVHRR device) in range of 137Mhz frequency.
ERS Information Reception Station (ERS IRS-1,7). Station for receiving low resolution remote sensing information. It provides receiving, visualization and extraction of S-range information from “Sich”, “NOAA”, “Resurs-04” and “MeteoSat” – type spacecraft.
Receiving Station (RS-8,2). Station is aimed to receive high resolution X-range remote sensing information; demodulate that information, pre-processing and further transportation of that information to the connection lines for further processing. It has maintained operation of METEOR-3M (MSU-E devise), “Sich – 1M” and “EgyptSat – 1” spacecraft.
National Space Facilities Control and Test Center uses remote sensing data for solving following tasks:
Moreover remote sensing data is being used for national defence and security interests.
Customers can get final information result of remote sensing data processing threw appeal.
For today a governmental institution that uses remote sensing data are:
Examples of solutions to specific tasks are shown on the respective maps:
National Space Facilities Control And Test Center was founded in 1996, according to the Decree of the President of Ukraine, the Center of distant space communications in the coastal region of Crimea peninsula, near the town of Yevpatoria. In 2014 to restore the operational control of the National Center and its affiliates by the State Space Agency of Ukraine made a decision on the relocation NCSFCT on the mainland of Ukraine, Kyiv.
