PhLEXSAT - Photo-Digital Channelizer for Flexible Digital High Throughput Satellites

Goal: The main objective of PhLEXSAT is the development to TRL5 of a photonic digital payload demonstrator. PhLEXSAT team, comprised by DAS Photonics, MDA, aXenic, Fraunhofer HHI, Argotech and Eutelsat, will take the next step in achieving the paradigm of the full-flexible Tbps-class payload by synergically mixing of Q/V bands, photonics and digital on-board processing within a new concept of photo-digital channelizer.

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 101004253.

Photonic components offer an advantage of minimizing the size, weight and power consumption (Swap) of a satellite communication payload. This paper presents how this can be utilized in increasing the capacity of Very High Throughput Satellites (VHTS) while reducing the cost at the same time. Photonics is capable of offering a limitless bandwidth in THz range at the band around 1550 nm while offering high data rates and frequencies with almost lossless propagation in an optical fibre. However, at present only a few demonstrations of photonic devices in non-critical equipment with limited degree of integration can be found in the satcom industry as we as in literature. With the advancement of the photonic technology, it is now possible to develop Tbps-like software defined photonic payload. PhLEXSAT project, funded under the European Union H2020, is led by DAS Photonics in cooperation with MDA UK, Eutelsat, Axenic, HHI Fraunhofer and Argotech.

Increasing the capacity of Very High Throughput Satellites (VHTS) while decreasing their cost has become an important area of interest. This can be met by minimizing size, weight and power consumption (SWaP) when accounting for the advantages photonic components bring. Photonics offers a limitless bandwidth in THz range at the band around 1550 nm. Lightweight and low volume photonic components are capable of handling high data rates and frequencies and offer almost lossless propagation in an optical fibre and immunity to Electromagnetic Interference (EMI). However, the use of photonic devices is currently restricted to a few demonstrations in non-critical equipment and with limited degree of integration. This paper presents the system design of an innovative photonic enabled digital payload called PhLEXSAT suited for future Terabit per second satellites by focusing on the advancement of the maturity level of key photonic technologies up to TRL5. The Tbps-like software defined photonic payload architecture incorporates advanced broadband photonic ADC and photonic DAC with digital processing firmware with a high degree of miniaturization and power-consumption efficiency. The selected photonic sampler architecture consists of two main components: Mach-Zehnder interferometer (MZI) modulators PIC and high-linear photodetector (HL-PD) PIC. The photonic sampler is driven by a space-grade pulsed laser which acts as a frequency clock. PhLEXSAT project, funded under the European Union H2020, is led by DAS Photonics in cooperation with MDA UK, Eutelsat, Axenic, HHI Fraunhofer and Argotech.
