@03ee4b50 from what I could see the uses were:

- the location, so lots of obvs examples there
- timestamps, in finance, energy, weather reporting, and apparently NTP servers use it too
- creative uses of the signals for other purposes, e.g. for earth observation research. Linked to some of those in the post

I've not come across anything else at the moment.

 @2d6fed24 those are areas thet benefit from the generic time/location messages, but there aren't messages specific to those domains I guess right? 

 @03ee4b50 no, as I understand it the satellites just broadcast standard signals and then they're just used in different ways.
