Space-based Software-Defined Radio
In the last decades, the area of wireless communications has undergone tremendous advances, with multiple game-changing technologies achieving global reach. One of the more promising technologies in this area is Software-Defined Radio (SDR). The TEKEVER Group currently offers several SDR-based products, mostly focused on terrestrial security and military applications.

TEKEVER SPACE is evolving the Group's SDR platform and products into the space segment, in order to develop and provide innovative products that simultaneously support satellite communications (e.g. telephony and broadband), inter-satellite communications and vehicle positioning and attitude determination capabilities. With a specific focus on reducing volume, weight and cost, while maintaining the reliability of communication modules and increasing flexibility (through in-flight updates, for example), TEKEVER SPACE is specifically targeting two promising mission scenarios:
  • Formation Flying:
    Based on the behaviour of many insect clouds in Nature, a swarm of small satellites has many advantages and applications. One of the key features of these distributed missions is the ability to assume determined cloud configurations and readapt when necessary, i.e. the ability to fly in formation. Another key element is communications, inside and outside the cloud, to achieve coordination among all participants and link with the ground station. The Space SDR concept fits perfectly in this scenario, especially for creating the cloud network for data sharing between satellites.

  • Planetary Exploration:
    Present in the roadmaps of every world space agency, planetary exploration is one of the main goals for the future, especially manned missions to the Moon and to Mars. To prepare these missions, a thorough recognition of the planet conditions must be made. Furthermore, any robotic or manned exploration mission will need to be supported by numerous sensors that provide spatial and temporal diversity. A set of sensors featuring SDR capabilities could be deployed to create a Wireless Sensor Network (WSN) to perform the measurements and automatically establish paths between the planetary surface and orbiting satellites. The network is fault-tolerant, since it can rearrange itself in case a node fails, and it could cover a large planetary area without requiring wide communication ranges.
