Hydrosat is zooming in on the thermal EO market.
Today, the company unveiled a new thermal mid-wave infrared (MWIR) program, called Nyktòs, which is designed to capture high-resolution imagery to complement the company’s lower-res, always-on, wide-swath imagery gathered through its planned Osiris constellation.
“With Osiris and Nyktòs, we have our own tip and cue capability,” CEO Pieter Fossel told Payload. “It’s really a family of products, or almost a Hydrosat ecosystem of products…It’s like having your iPhone and your MacBook. They do different things, but it can be nice to have two products from the same family.”
Fossel declined to share specifics on the expected resolution of the new Nyktòs imager, but told Payload it would be competitive with other thermal payload operators—namely SatVu, which offers imagery with 3.5-m resolution.
Heating up: The Nyktòs capability comes in response to growing demand for thermal EO data from European government customers. Unlike optical EO imagery, thermal EO payloads can capture data 24/7, allowing military customers to keep an eye on conflict zones even under the cover of darkness.
Hydrosat’s Osiris constellation aims to capture continuous imagery over a 340-km swath as each satellite flies overhead, allowing customers to spot changes on the ground without needing to task the satellites. With Nyktòs offering a higher-resolution perspective than Osiris, Hydrosat officials believe the company can lock down more of the market for satellite imagery—as customers can spot changes with Osiris, then task Nyktòs sats to take a closer look.
If you build it: To bring Nyktòs to life, Hydrosat is planning to open a new production facility in Europe. The aim is to inaugurate the company’s in-house manufacturing capacity in Europe, and form new relationships with European suppliers, to field a capability that can serve the sovereignty requirements of defense and government customers across the region.
While the company is unveiling Nyktòs as part of its bid to lock down a contract with the Greek government, according to Fossel, Hydrosat envisions Nyktòs supporting customers around the world—”targeted at defense and intelligence applications, although it will be great for industrial monitoring and things of that nature,” Fossel said.
Hydrosat is still shopping around for a location for its new facility, but Fossel told Payload it could be up and running next year, with Nyktòs payloads coming off the line as early as 2028.
