    They take a while to locate enough satellites for a fix. I'm not sure
    whether they use more battery power at this time, like a mobile phone, or
    which approach would be better for power management. At least while the
    thing is on you know it works. Of course, this is just skirting the issue,
    nibbling at the edges.
