Moore's law for weather satellites

Climate change is making the weather more severe and unpredictable, but weather satellites aren't keeping pace. For decades, it's been considered best practice to only use components that have flown in space before. As a result, weather satellites still use mainframe technologies from the 1990s.

At Care Weather, we iterate on our tiny weather satellites every two weeks, so we can afford to take risks on powerful modern electronics. We're bringing Moore's law to weather satellites. While the satellites are small, the impact is going to be big.

TECHNOLOGY TECH

Big plans, laser focus

We aim to one day measure all aspects of the global atmosphere in real time. Today, we're miniaturizing a decades-old radar technology for measuring wind speed and direction over the surface of the ocean called scatterometry. Current scatterometers only map winds around the world twice per day, leaving scientists and forecasters blind to the hourly variability of ocean processes that lead to hurricanes, floods, and droughts costing hundreds of millions of dollars and thousands of lives.

Mission 1: Global, Hourly Winds
Speed: ±1 m/s
Direction: ±20°/s
Range: 3-20 m/s
Resolution: 25 km
Global Revisit: Hourly
Latency: 15-30 mins

World's smallest satellite radar

To map global ocean winds every hour, we're building Veery, the world's smallest satellite radar.Veery's small size (1U CubeSat, size of a tissue box) makes it easy to launch the 50 satellites required to achieve our mission.

NEXT STEPS

Go for launch

Our first satellite, Hatchling v0.1, is assembled and slated for launch in February. Hatchling demonstrates the modern, miniaturized systems required for a weather satellite. Hatchling is capable of powering itself throughout its orbit through solar power generation, storing power in its batteries, monitoring its own thermal and electrical health, and communicating its status to the ground over a distance of more than 550 km!

Hatchling uses the 1p pocketqube form factor, making it one of the smallest satellites ever launched. This small size, enables the Care Weather team to iterate on Hatchling every 12-14 days. We started the hatchling project from scratch in December, so this iteration rate has allowed us to very rapidly arrive at a design with high performance and high reliability.

Radar upgrade in progress

We're not waiting for February. We're already hard at work on future satellite versions, including the future versions of hatchling with attitude determination and control (pointing), deployable solar arrays, and even a tiny pocketqube radar demonstration, which will be the smallest satellite radar in history. We're also working on the final satellite radar that will capture our ocean vector winds dataset.
