Increased Utility from Current Infrastructure 

Enabling greater utility and flexibility from capital intensive satellite antennas, with a simpler architecture, at significantly reduced capital and operational costs.


We have simplified the ground support equipment for Telemetry, Tracking & Control, and for Payload Data for Earth Observation and Communications satellites. Using off the shelf hardware, and systems expertise in have been able to produce a high-end transceiver using a software-defined radio.


Developing the whole chain to deliver real-time information, we are starting with the RF links


  • We have designed and extensively tested a highly flexible S/X-band Satellite Back End implementing complete standard downlink and uplink protocol stack from modulation to IP and return. This system is used on the KazSTSAT home station in Svalbard, exploiting full ARQ functionality for the SSTL configured the system.

  • The Back End Solution is simpler and more capable than heritage configurations and consists of only three main elements, providing duplex S-Band.

  • Since all signal manipulations are implemented in software, the software-defined radio back end is flexible enough to communicate with any number of satellites regardless of the coding, encapsulation, and modulation (for S-band) schemes.

  • The X-band of the Back End is based on a COTS High Rate receiver and High-End PC with downlink protocol stack and running the satellite manufacturer’s application. Scalable to support up to 900 Mbps.

  • Additional modulations, coding, and encapsulation protocols are implemented in software. The system provides a Network interface with the Spacecraft Operations Centre (SOC): transparent connection to the SOC LAN segment using Ethernet over IP via VPN using public Internet connections at both ends.

  • CSS SDR based back ends can be available in S, X, Ka, Ku bands, for payload and TTC.
