Weather Satellite Constellation

To improve global forecasting technology and capabilities, we have designed proprietary radar-equipped satellites and will begin launching dozens into space over the coming years.

Our small-satellite constellation will be a first in the history of the weather industry, and bring critical weather radar coverage to the entire globe.

We are building the first-of-its-kind proprietary satellites equipped with radars, and launching them into space to improve weather monitoring and forecasting capabilities.

It's All About
Radar in Space

Known for pioneering a number of weather technology advancements in recent years, Tomorrow.io’s radar-equipped small-satellite constellation represents a first in the history of the weather industry.

Radar is used to power weather forecasts. Radar is a critical sensor driving weather forecasts – they provide detailed information about precipitation and cloud structure that no other sensor can see.

More than 70 years after radar was invented, more than 5 billion people still live outside of radar coverage, making even the most basic forecasts a dream for the vast majority of humanity. Even in the United States, there are still many regions with limited or no radar coverage.

Frequently asked questions

Radar is used to power real-time situational awareness, short-term nowcasts, medium-term forecasts, and climate studies. Radar is often the critical sensor that drives weather forecasts, providing detailed information about precipitation and cloud structure that no other sensor can see.

Deploying radar on the ground to close this gap would be practically impossible – we can’t cover the oceans, and it’ll be very difficult to get to remote regions and vast land areas such as those in Africa, Latin America, and SE Asia. It’s been about 70 years since the first weather radar was invented, and we still haven’t been able to cover but a fraction of the globe. See this map from the World Meteorological Organization for more details.

Roughly 5 billion – most of the population of South and Central America, Africa, Asia, and the Middle East. Even in the United States, there are still many regions with limited or no radar coverage.

There are only a handful of instruments in space today that directly measure precipitation. NASA’s Global Precipitation Mission core observatory satellite is the leading one, and it sees every point on earth roughly once every 2.5 to 3 days.

We will get down to about 1 hour revisit time, so more than 50X improvement on the current state.

Most existing weather radar satellites are planned to be decommissioned in the coming decade, and some within just a few years.

Tomorrow.io’s radar performance is expected to be comparable to the current state-of-the-art (GPM DPR) and in some aspects potentially outperforms it. The overall constellation however will provide a significant increase in the total revisit time since we will have far more than a single satellite.

Yes. We plan on launching to a mix of orbits including sun-synchronous orbits so that we can cover every point on the globe.

We expect the initial satellites to launch in the second half of 2022 and for the system to reach initial operational capability in 2023.
