And then afterwards it takes a lot of work to calculate the navigational solution from these raw measurements. This basically keeps a microprocessor busy which uses energy. One trick people do for ultra-low energy non-realtime GPS tracking of wildlife is to store the “raw” radio samples and do as little processing on the tracking device as possible.[1] Then once the tracker gets back they batch process all the samples recorded and reconstruct where the animal has been. That is obviously a tradeoff…</p><p><a href="https://hackerpaper.kaipfister.de/p/2207.06310/">Paper and discussion history</a>. A mention is not an endorsement.</p>eess.SY
