Note that all this also depends on network coverage. If the node can use SF9 or better, then it can send 6 bytes for two 24 bit coordinates every 10 minutes, all day long. Or much more often when not sending all day.
(On the other hand: some say a moving node should use SF12, some others say that’s making things worse. See references at Best practices when sending GPS location data which is also work in progress, and needs some clarifications.)
