ESA Awards $1.1 Million Contract to Space-Proof Irish Photonic Frequency Technology
Optical Frequency Generator Targets Next-Generation Satellite Payloads Across Higher Frequency Bands
The European Space Agency has awarded a €1 million (approximately $1.1 million) contract to Dublin-based Pilot Photonics to advance the space readiness of the company’s Optical Frequency Generator Unit, or OFGU — a photonics-based alternative to the electronic frequency generation hardware now common in satellite payloads.
“This project will accelerate the OFGU’s readiness for space, culminating in space-environment validation after which early demonstrations in orbit can commence.”

The contract, announced June 4, 2026, funds space-environment validation of the OFGU with the goal of enabling early in-orbit demonstrations of the technology. The award builds on earlier development work completed under the EU-funded projects PICOMB, ACTPHAST 4.0, and PhotonHub Europe.
Conventional satellite payloads rely on electronic frequency generation units. That architecture faces mounting pressure from data-intensive applications — live streaming, remote work, and augmented and virtual reality — that are pushing existing satellite communications infrastructure toward its limits. A growing number of satellites in orbit has compounded the problem by crowding traditional frequency bands.
The OFGU addresses those constraints by operating in the optical domain rather than through standard radio-frequency electronics. The unit delivers frequencies from 8GHz to 220GHz with low noise and high power efficiency from a single, compact source. In one configuration, it produces stable, low-phase-noise RF carriers for use as a local oscillator in satellite payloads, feeder link transponders, and ground stations. In a second configuration, it delivers optical outputs for on-board signal distribution in RF photonic satellite architectures.
“This project will accelerate the OFGU’s readiness for space, culminating in space-environment validation after which early demonstrations in orbit can commence,” said Dr. Amol Delmade, OFGU Product Lead at Pilot Photonics.
Dr. Nikos Karafolas, Technical Officer at the European Space Agency, said photonic technologies are becoming increasingly important for space applications. “There is a need for technologies like the OFGU to offer higher Q, stable, local oscillator for existing RF and for future Photonic RF architectures,” Karafolas said.
The contract also carries significance for Ireland’s broader position in the European space economy. Barry Jennings, National Delegate to ESA at Enterprise Ireland, said the award reflects Ireland’s growing capabilities in the sector. “Pilot Photonics is developing highly specialised technology that addresses a real and urgent need in next-generation satellite infrastructure — and doing so at the frontier of what’s possible in integrated photonics,” Jennings said. “The Irish Delegation to ESA is committed to supporting companies like Pilot Photonics as Ireland continues to build a strong and distinctive presence in the European space sector.”
Pilot Photonics has published a technical whitepaper on the OFGU detailing its comb source technology and application areas.
