In CubeISL, based on the OSIRIS4CubeSat development, the technology of laser communication is transferred to the intersatellite domain. In addition, the data rate in the connection to the earth is increased tenfold.
In order to be able to use the advantages of Free Space Optical (FSO) communication in constellations and mega constellations, the OSIRIS4CubeSat terminal is being further developed in CubeISL to establish bidirectional data transmission via laser between two (and more) satellites - in addition to the connection between satellite and ground station.
The modular approach in OSIRIS4CubeSat allows an easy extension of the basic development by the required subsystems. In addition to a receiver and a powerful transmitter, CubeISL will have its own onboard computer for data processing. This enables, in addition to the inter-satellite link, a tenfold increase in the data rate for satellite-to-ground transmission.
OSIRIS CubeISL - Measurement campaign on Teneriffa
ESA Optical Ground Station on Tenerife during a measurement campaign on the Canary Islands. The connection between two CubeISL terminals and the Optical Ground Station was demonstrated. The terminals were operated on different islands, Tenerife and La Palma.
Das Terminal beruht auf der Basistechnologie des OSIRIS4CubeSat-Terminals. Es wird den Technologietransfer von Direct to Earth (DTE) zu Inter-Satellite (ISL) demonstrieren. ISL und DTE sind mit demselben Terminal möglich.
