These are sheep, not aircraft.
Well that adds a whole new dimension, and you'll need all sorts of veterinary advice on that I should think. Not to mention the animal research ethics people getting on your case.
Are you trying to measure the temperature of the animal, or the outdoor temperature ?
Does this help? Can anyone think of better figures to use for the different modules/shields?
Well, not exactly. Those numbers seem to assume continuous operation. These are sheep, not aircraft. Put the processor, GPS, radio and all to sleep for some interval. A few questions:- How often do you need to sample position and temp? Sheep and temp don't move fast. Every minute? Every 5 minutes? Every 30 minutes?- What does "5 ha" mean? How big is that in square miles?- Are the sheep expected to be randomly distributed throughout the area? Or do you expect they will cluster all together in one area?
