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.

Japan successfully launches first military communications satellite

Japan has successfully launched its first military communications satellite Kirameki-2 (kee-RAH-meh-kee 2) satellite.

It was launched on board of H-2A rocket that lifted off from the Tanegashima Space Center in southern Japan. The satellite separated from the rocket and entered a designated orbit.

Key Facts
  • The Kirameki-2 satellite has been designed to upgrade Japan’s existing communication network in the face of China’s increasingly assertive maritime activity and North Korea’s missile threat.
  • It is the first of three satellites that will replace three civilian satellites currently used by Japan’s military. The new satellites will allow military units to communicate on a high-speed and high-capacity network.
  • These satellites aimed at stepping up Japan’s emergency response capability in case of natural disaster, China’s maritime activity from southern Japanese waters to South China Sea, as well as missile threats from North Korea.
  • They will be also used by Japanese troops operating overseas as part of international peacekeeping operations, including those off the Somali coast and in South Sudan.
