This project focuses on the development of a hermetically packaged, fiber coupled photodiode for Ka-band with a bandwidth larger than 20 GHz capable of handling incident optical input powers of 120mW. Such photoreceiver modules are key building blocks of photonic RF links with very high dynamic range that will be extensively employed in microwave photonic payload designs.
The Micro Remote Terminal Unit (μRTU) provides interfaces for telemetry acquisition, telecommand execution and power to peripheral units on board a satellite. These interfaces are implemented in a modular way that allows the prime of the satellite to change the number and configuration of interfaces according to mission specific needs without the need to change hardware.
In satellite communication new frequency bands are being used to handle more and faster communication. For RUAG Space AB to remain a leading independent supplier of converters and receivers, being able to deliver space qualified converters operating above Ka-band is essential. The Ka/Q-Band Up Converter Programme objective is to complement and to further strengthen RUAG Space converter and receiver products by performing this activity in the Q/V Converter product area.
«Satellite trunking» is referring to very different services and usages. Here, we define trunking as the provision of high data rate point-to-point links for professional use.
Up to now satellite trunking services (including mobile/cellular backhaul) are only provided by GEO satellites over regional coverage, with the notable exception of the equatorial O3B MEO constellation.
Mega-constellations are developed to provide Internet access services to private customers.
The future would be to rather use LEO/MEO constellations for the provision of high speed trunking services to professional customers.
The question is : will be LEO/MEO constellations the right solution for the next generation of high speed trunking services

One of the major obstacles that the NewSpace market is faced with, is the incompatible costs associated with the operations of the spacecraft and the management of the data through the ground network offerings. Moreover, the limited frequency spectrum, has a damping effect to the growth of this market, as it severely limits the number of spacecraft that is possible to share this spectrum and get the necessary ITU frequency allocation within timescales compatible with the aggressive schedules of this market. Project GNNetE aims to address those problems directly.

In this program, two replacement subunits of the LCT were developed and qualified. The units are the Fame Unit Structure (FUS) and the Telescope Unit (TLU). These units replace previous units and have to comply with the existing LCT design. This development took into account experience gained from the previous designs and handling to achieve a robust design and decrease overall cost of LCT while maintaining the known performance requirements.
TLU and FUS have significant influence on the LCT mechanical design. Therefore, a LCT mechanical demonstrator (LMD) was built to qualify the required mechanical loads.

Low-Earth-orbit (LEO) satellites are flying in an altitude between 200km and 2000km above Earth and hence are limited in the amount of time they are visible to a ground station (typically around 20 minutes). This is limiting the amount of data that can be exchanged. However if the data is relayed to a geosynchronous-Earth-orbit (GEO) satellite, the available LEO satellite data transmission time (and amount of data) can be drastically increased.
This project covers the design and the development of the link and network layer mechanisms required to support end-to-end unicast data connectivity over inter-satellite links in small satellite constellation networks. SPIDER stands for Small Platform Inter-satellite Data Exchange Routes, being an obvious reference to the spider’s ability to create webs, which is precisely the purpose of this project.
Since satellite operators aim for more bandwidth to increase data throughput and capacity new system and payload concepts are required, leading also to the demand for new equipment. One promising option to increase capacity for HTS systems is moving the feeder link from Ka-band to Q/V-band. The focus of this activity targets the development of Q-band linearisers.
On-board handling of higher-layer protocols via an ad-hoc router device makes it possible to provide satellite connectivity completely by-passing the (possibly) clogged/compromised terrestrial infrastructure, to facilitate IP mobility, to reduce traffic load on satellite uplinks by deploying IP multicasting on board the satellite, and to provide true packet-by-packet end-to-end connectivity between satellite terminals in meshed configuration or ISL environment.
