Zaitra s.r.o.

The challenge of Earth observation from space is no longer launching satellites — it is knowing what to do with them once they are in orbit. Next-generation sensors aboard satellites produce enormous volumes of data, but the transmission capacity to ground stations remains a critical bottleneck: available bandwidth is expensive, limited, and not always accessible at the right moments. Zaitra, a startup active in the deep tech and space sector, has chosen to tackle this bottleneck with a radical approach — processing data directly on board the satellite before transmitting it. Instead of sending terabytes of raw images to the ground, the satellite processes, filters, and compresses data in space, transmitting only the information that is truly useful. The savings in bandwidth and transmission costs are significant; the latency between data acquisition and use is drastically reduced. Compatibility with Simera xScape, a satellite imaging platform, indicates that Zaitra works in close integration with the existing hardware ecosystem, developing onboard processing solutions that slot frictionlessly into Earth observation mission workflows. The market is satellite operators, space agencies, and organisations that use Earth observation data for environmental, agricultural, security, and crisis management applications. In a sector where data costs remain a limiting factor for many applications, the ability to structurally reduce them represents a concrete competitive advantage.
