The scope of project EIVE (Exploratory In-Orbit Verification of an E/W-Band Satellite Communication Link) is the development and test of one of the world's first in-orbit verification of a communication link in the E-band in order to allow new frequency ranges for broadband satellite communication and to ensure the steadily growing demand for higher data rates.
A data downlink in the frequency range 71-76 GHz from a nanosatellite to a ground station is planned. Detailed link budget calculations show the feasibility of a transmission in a polar low-earth orbit with a very large bandwidth of 5 GHz while using realistic compact antenna dimensions.
The EIVE consortium consists of different German institutes and companies:
- The Institute of Robust Power Semiconductor Systems of the University of Stuttgart develops the E band payload and will act as the principle investigator.
- The Fraunhofer IAF as well as the Radiometer Physics GmbH develop the E-band radio frequency equipment utilising GaN and GaAs semiconductor technologies.
- The EIVE project is supported by TESAT Spacecom who offer their expertise in the field of space radiation and electronic development.
The Institute of Space Systems of the University of Stuttgart is responsible for the design, integration, and testing of the satellite bus. Further, the IRS manages the satellite operation utilising the IRS ground station.
