Global science project links Android phones with satellites to improve weather forecasts

Read the full story from The Verge.

Collecting satellite data for research is a group effort thanks to this app developed for Android users. Camaliot is a campaign funded by the European Space Agency, and its first project focuses on making smartphone owners around the world part of a project that can help improve weather forecasts by using your phone’s GPS receiver.

The Camaliot app works on devices running Android version 7.0 or later that support satellite navigation. The way satellite navigation works, phones or other receivers look for signals from a network of satellites that maintain a fixed orbit. The satellites send messages with the time and their location, and once it’s received, the phones note how long each message took to arrive, then use that data to figure out where on Earth they are.

Researchers think that they can use satellite signals to get more information about the atmosphere. For example, the amount of water vapor in the atmosphere can affect how a satellite signal travels through the air to something like a phone.
