And then it is very energy efficient.
It only sends the information maybe once a day or every few hours, depending.
And then only very little information.
So it analyzes the behavior of the animal on board, on the tag, and then sends the summary to the satellite when the satellite is overhead.
Wow.
And how big are these tags?
Well, the big ones are now actually four to five grams.
So like a little finger.
The smallest ones that are coming in fall this year and then will be used next year on small migrating birds, they're only one gram.
And that's really where we always wanted to be because we want to track the bats across the world, the small birds like swifts.
We want to do swifts and swallows to really understand where these aerial insectivores are going into Africa, into Indonesia, into the Congo, into the Amazon, and then have a global connectivity of these information systems.
One gram.
That's extraordinary.
Yes, so in the four-gram ones, and they are shrinking, we have GPS accuracy.
In the one-gram ones, we do some kind of nifty location algorithms, and we get it down to a five-kilometer radius.
But on that scale, going from Ireland to Angola or from Sweden to Ethiopia,
that information is sufficient.
And especially it's important that we want to understand, is the animal alive or dead?
Because we need to understand where our animals are dying.
We lost so many of those birds in Europe and in North America.
