Pilot Photonics has developed the world’s smallest and most versatile optical comb source based on photonic integration. Through PICSAL, its broad applicability to space applications including inter-satellite communication, fiber optic sensing, frequency generation, and frequency metrology is explored.

  • PreDem

    The challenge is that increasing throughput simply by increasing frequency reuse results in significant intra-system interference for co-channel beams in multi-beam satellite systems. The solution is to apply joint processing of the signals intended to the different beams at the gateway for interference management. This processing, precoding, ‘reverts’ the impact of the satellite RF channel and interferences.

  • KaMobile

    This study analyses the requirements, constraints and trade-offs for a SatCom system for receiving multimedia services in a mobile, on-the-go (e.g. automotive) setting using Ka-band frequencies. The analysis targets both technical as well as business oriented points of views and uses a software-based physical layer simulation to verify the feasibility of the identified approach. Results reach from technical answers like waveform design and end-to-end performance, over the quality of the experience for the user up to economic considerations like total cost of ownership and business cases.


    The JAMES CCN3 project goal is the development of a RF test set-up using optical fibres as links between RF test bench and telecommunication payloads in AIT. The first phase was dedicated to design the test set-up allowing gain stability improvement, to realize a representative breadboard and test it over temperature. The second phase focused on the study and bread-boarding of a representative use case, featuring hundreds of accesses, with a solution involving optical wavelength multiplexing. It resulted in the validation of an end-to-end set-up, including elaboration of a TVAC compatible RF power probe. The solution proved particularly suited to uplinks, while more work is required to operate in downlink, specifically due to sensitive components bias.


    The SITKA project covers the development of a highly integrated, low power, low cost, RF transceiver ASIC (Application Specific Integrated Circuit) targeted at VSAT satellite system ground terminals. The ASIC is a critical component for two way communications equipment which supports DTH (direct to home) interactive services, broadband connectivity and enterprise services in Ka frequency band.
