Problem
The current small satellite launch market lacks flexible and responsive options, often requiring customers to wait for rideshare opportunities or accept sub-optimal orbits. Existing solutions also lack the ability to provide extended orbital exposure for payload testing and validation.
Solution
Sidereus Space Dynamics is developing the EOS personal launch vehicle, a single-stage orbital launch system designed for rapid and precise deployment of small satellites. EOS offers flexible launch schedules and target orbit delivery, enabling customers to deploy microsats and nanosats exactly when and where they need them. The platform also provides an advanced orbital testbed, allowing for extended exposure of payloads to real space conditions such as microgravity and radiation, with onboard telemetry and power solutions to support testing and validation.
Target Audience
The primary target audience includes organizations requiring rapid deployment of small satellites, such as Earth observation companies, IoT satellite constellations, and space research institutions, as well as companies needing orbital testing and validation of new space technologies.
