In this GSTP activity, Syrlinks developed a breadboard model of an S-band transponder demonstrating full ranging capabilities.

The previous version of the transponder, without the ranging functionality, was developed under the CNES Myriade Evolution program, which is a platform for micro-satellites.

Develop a low-cost S-band transponder, based on class-3 components, and providing coherency and ranging functionalities.

A bread-board model was completed and delivered to ESA. Full functional validation, based upon laboratory measurements, was successfully undertaken. The full ranging and coherency functionality was validated under typical operating conditions.
