Heinrich Hertz (also H2Sat ) is the name of a planned German communications satellite , financed by the German Aerospace Center (DLR) and built by OHB Systems.
The Heinrich Hertz Mission aims to investigate new types of communication technologies in cooperation with universities, scientific institutes and industry. Another aim is to build up competencies in the field of military satellite communication in Germany. The mission is named after the German physicist Heinrich Hertz (1857–1894).
planning
On behalf of the Federal Ministry of Economics and Technology , the Bremen-based satellite manufacturer OHB System AG examined the feasibility of the project in a preliminary study (phase 0). The feasibility study (phase A) was completed in 2010. OHB-System and its partner EADS Astrium had overall responsibility . OHB System was also responsible for the satellite bus. Tesat-Spacecom was responsible for the payload . Planning phase B was carried out from 2011 to 2013. On June 28, 2017, the contract for the project phases C and D + Start was signed. The launch of the satellite is planned for 2021, the budget is 310.5 million euros for construction and launch plus development costs of 11 million euros from planning phase B and an as yet unknown amount for 15 years of operation.
Planned payloads
About 30 developments become payloads. Here is a selection of possible technologies:
- LISA: Inter-satellite antenna in the Ka-band with electronic swiveling
- MEDUSA: Multipoint antenna in the Ka-band to reduce complexity
- VERSA: Distribution network to reduce complexity with syntactic metal foam as the carrier material
- KERAMIS: Ceramic microwave circuits based on LTCC multi-layer technology
- LIQUIDA: liquid crystal controlled phase shifter
- TWTA: mini amplifier tube (Ka-band)
- MPM: V6 Microwave Power Module for the implementation of up to 500 W HF power
- FDOC: Linearized Ku-band tube amplifier
- FOBP: Fraunhofer On-Board Processor, a fully in-orbit reconfigurable processor
- NEXT: Several new error correction methods (network coding, multi-participant detection, fountain code )
- GeReLEO-SMART: Geostationary relay station for Ka-band communication with LEO satellites
- HSB: Hybrid Sensor Bus, combination of electrical and fiber optic sensor system
New technologies are also to be tested on the ground, such as:
- SANTANA: Ka-band terminal (with digital beamforming English beamforming )
- MoSaKa: Mobile satellite communication (Ka-Band) for use in the event of a disaster
