Interestingly the app is made in Unity. A couple of oddities, but having this leader board function was definitely an interesting idea.

Sadly either my old phone's GPS is not great or my windowsill's viability to satellites just isn't great. It'll be very interesting to see the data pipelines they have to clean up the mountains of data they're going to be receiving.

The fact that they can use the delay of the satellite signal to predict rainfall, is pretty impressive. It immediately links this app to more data for weather prediction, which might lead to better weather predictions. I wonder how they would measure that on an android phone. Does android expose such low-level delays to the user? Is this not handled by a GNSS chip in hardware, or the OS driver/kernel?

Newer Android versions have fairly low-level APIs - not supported on all phones, but some expose quite a lot of detail.

Here is an example of pretty stunning amount of visual detail provided by one of popular GPS data app on Android: https://play-lh.googleusercontent.com/lT3TpHarUx89Z7HIf043aU... At least I can confirm it works will all navigation constellations on Samsung S10.

Interesting project, can't wait to help ESA out a bit. Seems like the phone will just track the satellites via GPS, so it's not even that battery intensive. Overnight left charging could provide a lot of data. The fact that there's a leaderboard makes it even more gamified.

Don't phones use a combination of various global positioning systems these days, including glonass and galileo?

Actually how much detailed GPS information can phones access? Most 'common' apps will use the wider 'location services', which combine GNSS data with things like known wifi points and 3/4/5g radio towers to provide better accuracy.

Can become very popular if they link it with some kind of crypto mining, just keep your mobile phone at window and earn crypto!

Sigh. You're putting your processing power to work for a wealthy corporation in the hopes they will give you scraps in return, and / or that those scraps will become worth more in the future.

Crypto idealism is long dead, it's all about making money now.

Almost as good as having a crypto miner in your anti-virus software, which is practically a contradiction in terms.
