Latitude and the EIC Accelerator: A Rocket Still Waiting to Fly

Latitude, registered in Reims in 2019 as Venture Orbital Systems and led by co-founder Stanislas Maximin, is developing Zephyr, a two-stage rocket powered by its own 3D-printed Navier engines, to launch small satellites to low Earth orbit. Its EIC Accelerator project, ZEPHYR, "Development of an innovative GPM for the ZEPHYR microlauncher", receives an EU contribution of €2,497,250 and runs from December 2024 to November 2026, according to CORDIS. The GPM, or ground proximity means, is a transportable launch pad system controlled by the rocket's own computers, meant to let Zephyr fly from any spaceport pad without purpose-built ground structures.

After the first year, the report says, the "Simplicity" pre-qualification campaign met all its objectives, validating the electrical, fluid and mechanical systems of the smart launch pad and its interfaces with a second-stage engineering model. But the complete second stage was not yet available, so coupled tests remain to be done, and the project's final work package, the first launch campaign, has been "delayed to early 2027", according to CORDIS. That is after the project ends. When Latitude raised a $30 million Series B in January 2024, it targeted Zephyr's first flight for 2025, according to TechCrunch; in July 2025 the target was 2026 from French Guiana, according to SpaceNews.

Where Latitude Stands Now

Latitude is building and testing. It runs its Titan test centre on an 8-hectare former NATO site at Vatry, according to Wikipedia, and announced a move to a larger factory in July 2025. The French register lists a workforce band of 50 to 99 and capital increases published in August 2025, May 2026 and August 2026, according to BODACC; the amounts and investors were not announced. Its accounts after 2021 are not in the public INPI dataset.

The Technology: A Launch Pad That Travels

Latitude says its system avoids the launchpad-specific design a rocket normally requires. Latitude's smart GPM acts as a "stage 0" that ships with Zephyr, supervised by the rocket's on-board computers, with a simplified interface to the ground. The idea is to launch from several spaceports without building dedicated infrastructure, which Latitude says makes rescheduling easier and cuts costs. The concept only proves its worth when a rocket flies from it.

What the EIC Award Promised, and What the Record Shows

The project ends in November 2026, so a final judgement is premature. The ground system itself is on track, but the flight that would validate it will not happen within the project. On the commercial side, the report lists a commercial plan, a payload user's guide and a sales team; no launch contracts are named in it.

The Money

Latitude's disclosed equity is a €10 million Series A in 2022 and a $30 million Series B in 2024. Its last public accounts, for 2021, show revenue of €27,920 and a loss of €143,132, according to the INPI financial ratios. No EIC Fund investment has been announced.

What Cannot Be Checked

Why Europe Should Care

Zephyr is aimed at small satellite operators who want a dedicated ride rather than a shared one on a larger rocket, the EIC report says. Latitude's value to Europe depends on getting Zephyr off the ground.
