Marathon: Roscosmos to venture into Internet of things (IoT) with the launch of new satellite system

Russia’s state space corporation (Roscosmos) has planned to venture into Internet of things (IoT) with launch of new satellite system named ‘Marathon’. The new satellite system will be part of Russia’s Sphere satellite constellation, which will be fully established by 2026. The number of satellites in Marathon system are not revealed yet. The federation’s GLONASS navigation, a satellite communication system and data relay satellite set-up will be other equipment in the constellation.

Background

Russian President Vladimir Putin has approved Sphere constellation project, which involves the construction and deployment of 640 satellites. There are several segments of the satellite communication. USA’s Iridium has been long operating successfully on voice satellite communications market. OneWeb and Starlink dominate broadband Internet segment. IoT is the third segment of the satellite communication. Work in this segment will be successful if services are provided at lowest prices as the other systems also provide such services as well.

Internet of Things (IoT)

IoT is a network of devices such as smartphones, wearable devices, home appliances and vehicles, connected to internet, which enables these objects to connect and exchange data. Blockchain technology has potential to address security risks to IoT as it provides a shield against data tampering by labelling each block of data.

Russia successfully launches Glonass-M satellite using Soyuz-2.1b carrier rocket

Russia has successfully launched Glonass-M positioning satellite on board of Soyuz-2.1b carrier rocket from the Plesetsk space centre in Mirny, Arkhangelsk Oblast. The satellite is part of GLONASS network GLONASS (Russian acronym for Global Navigation Satellite System) which provides real-time positioning data for surface, sea and airborne objects around globe, at accuracy reportedly at par with US Global Positioning System (GPS). With this launch, there are now total 26 Glonass satellites in orbit.

Glonass-M satellite

It was built by Reshetnev Information Satellite Systems (formerly NPO-PM). It has design life of 7 years which is significantly higher than that of previous generation of Glonass satellites. It is about 2.4* 3.7 meters in size with solar array span of 7.2 meters. It has two deployable solar arrays which provide 1600 watts of electrical power. The heart of the satellite is Caesium atomic clock that provides accurate timing reference needed to generate navigation data.

Glonass

Glonass is Russian Satellite Navigation System considered as counterpart to GPS of US, Galileo of European Union (EU) and Beidou of China. It is being used by military as well as commercial customers. It provides real time position and velocity determination at accuracy that can be compared to that of GPS. It has accuracy of 100 meters as part of public segment and 10 to 20 meters for military users. Its time accuracy is under 1000 nanoseconds. Glonass Program started back in 1976 when development was initiated. The first Glonass launch took place in 1982 and the constellation became fully operational in 1995. Currently, second generation Glonass-M satellites as well as Glonass-K1 satellites are in service. Glonass-K2 and KM satellites are under development.
