without much depth
How much “depth” do you expect to get out a group of animals acting “mostly” natural and without a single line of human dialog? With those limitations, I think it excelled. There were even a couple tearjerker moments, for me at least.
So…use the barometer in tandem with GPS? This is shit I can easily track from my personal Homassistant server.
Also, you know how to make GPS more reliable, secure, and redundant? You launch more GPS satellites.
