Launched on April 14, 2023, Tomorrow-R1 is the world’s first commercially built weather-radar satellite. It orbits at 500km above Earth in a polar orbit and carries a Ka-band radar ideally suited for detecting precipitation and critical ocean parameters. Tomorrow-R1 marks the first step in deploying the Tomorrow.io constellation of active and passive sensors, which the company hopes will achieve breakthroughs in global weather forecasting and climate observation, with near real-time scans of precipitation and atmospheric profiles for any point on Earth.
