How To Turn Your Android Phone Into A Space Tracker?

Your modern smartphone is a powerful tool. Besides the typical applications you can perform with your device, it can do a lot more than you can imagine. One of the most exciting use cases is using your phone to receive and monitor satellite data.

Using the European Space Agency’s (ESA) Camaliot application, you can easily collect satellite data from the Global Navigation Satellite System (GNSS). Here’s how to use the Camaliot app to turn your phone into an area monitoring device.

What Is Camaliot and How Does It Work?

steward It is an application that helps to collect raw data from GNSS. GNSS itself is a group of satellites that orbit the earth and help provide different critical data such as positioning and navigation. To put it in context, one of the most common GNSS is GPS, whose use is ubiquitous in our daily lives.

Due to advances in mobile technology, many phones can receive satellite data from GNSS thanks to dual-frequency satellite navigation receivers. The Camaliot app leverages these satellite navigation receivers on your phone to help collect data.

according to ESAMore than 50 phone models have these receivers. The primary purpose of the Camaliot app is to help gather satellite data from GNSS that scientists can use in their research to help “build new Earth and space weather forecasting models” through machine learning.

“Using crowdsourced GNSS data from many mobile phones around the world, we hope to create better inputs into weather forecast models for more accurate forecasting of local precipitation events,” Camaliot’s website states. If you are a space lover, you can also download this data and use it in your projects. Even if it doesn’t help you Follow Starlink’s satellitesCamaliot is a handy app.


Unfortunately, the app is only available on Android. However, all is not lost because it is different. Apps for space buffs on iPhone.

Using the Camaliot App to Monitor the Area

The Camaliot app is available on select Android phones and can be downloaded for free from the Google Play Store.

  1. First make sure GPS is turned on, then launch the app. If you are opening the application for the first time, follow the first prompts.
  2. Next, tap the hamburger menu in the bottom right and Registration Login To create an account or log in
  3. Go to the home tab and Start Logging to collect raw satellite data. Optionally, enable Continuous Mode before hitting Start Logging Button to allow the application to automate the logging and loading process.
  4. You can tap after logging starts. Login Background to keep the app running in the background.
  5. Faucet stop log if you have not enabled to stop the collection of satellite data Continuous Mode, the application will ask when you want to load the collected data. You can choose Now or Later on.

Selecting Now will get you to: To upload Click the icon tab and the data will be loaded automatically. A Log file upload successful The prompt will confirm that the process is finished. If you choose Later, you will have to go to the Install tab and manually To upload Click next to the log file to start the process at any time.

Use Upload All Press the button in the upper right corner of the Upload tab to upload all your local log files. Note that you need to connect your phone to the internet to upload files. If you want to use these logs, you can download them as .rnx files by pressing the file icon with RNX text.

How to Ensure Optimal Measurements

For better results, the app recommends placing your device where the sky can be seen. Additionally, do not move it while collecting data. If you need more accuracy, the measurement quality indicator should guide you. Aim for a green indicator icon, because it means you’re collecting measurements well. Any other indication means something is wrong.

Different problems can lead to a non-ideal measurement quality indicator. You may be collecting observations from a small number of GNSS satellites, your device may be having trouble recording data due to its location, your phone may be constantly moving, or you may not have your GPS activated.

Monitor Space Using Your Phone

Camaliot app is a powerful app that lets you collect satellite data using your device. While the app was primarily created to assist crowdsourced science, you can also benefit from using the collected data in your own projects. The app helps scientists predict weather patterns more accurately, making your device a powerful tool and a force for good.
