Visible and infrared remote sensing

SR SAR technologies are based on scanning and modeling the landscape using a radio signal reflected from the Earth. SAR imagery includes information about the phase and polarization of the reflected electromagnetic wave. That provides new opportunities for Earth observation compared with the usage of optical satellite systems.

Our satellite constellation will include 12 small satellites, which will allow not only to observe the entire Northern Sea Route with revisit time of less than 3 hours, but also to provide continuous radar monitoring services around the world

SR SAR satellite data is suitable for applications in the following areas:

- monitoring of floods and ice cover;
- detection and control of water pollution;
- crop assessment and forest monitoring;
- mapping and inventory of land use;
- control and inform people during natural disasters and emergency situations.

Radar sensing

The commissioning of SR CMS, based on the measurement of greenhouse gas concentrations and fluxes using infrared spectrometry methods, will allow you to quickly monitor, evaluate and identify sources of emissions and sinks of both natural and anthropogenic greenhouse gasses, areas of emission and absorption.

There are 3 main components of SR CMS: space infrastructure, ground infrastructure, software and hardware systems. SR CMS will include 60 small spacecrafts, 2 ground stations, 100 fixed and mobile ground stations.

Greenhouse gas monitoring

SR CMS will allow solving urgent scientific and technical problems for various sectors of the economy:

- carry out continuous monitoring of greenhouse gas emissions from the main emission facilities: pipelines, industrial enterprises, fields, logistics hubs;
- carry out monitoring a specific object, region or an entire country;
- assess the amount of environmental and economic damage from the emissions;
- assess the absorption capacity of natural ecosystems (forests, swamps, etc.);
- measure the surface temperature of the seas and oceans;
- measure the temperature of the underlying surface;
- to determine the wind speed and moisture level in the atmosphere.

Within the framework of commercial cooperation agreements, SR Space is developing spacecraft for optoelectronic remote sensing of the Earth with high and ultra-high resolution: SR OKO-1, SR OKO-2, SR OKO-3.

The development of a space system of high-speed broadband Internet access is of particular importance for our country due to its geographical location, the distribution of natural resources and socio-economic infrastructure. That is a critical technology, being a basis for the economy built on Big Data: millions of unmanned vehicles and drones, hundreds of millions of CCTV cameras (street, corporate, technological), robotic systems that control tens of thousands of wells in real time.

The deployment of an orbital constellation of 672 spacecrafts will provide broadband Internet access in remote and hard-to-reach areas in Russia, including the Arctic zone.

Various organizations in the field of oil and gas production, geological exploration can become users of that satellite broadband communication system; monitoring services for air, sea, river and land transport, as well as telecom operators in remote and hard-to-reach areas of the country.
