16 June: PTTs changed protocol
During the summer period, where the Brent Geese will be less mobile (either because they breed and have nests and chicks to attend or because they moult and can't fly), the transmitters have been programmed so they store less GPS locations and submit data to the transmitters less frequently. So we have to wait two days for news to come out of the sky, so to say. We use this protocol in order to avoid loosing to much battery power - so the PTTs are 'fit for fight' when the birds start moving around again after moult or when their goslings fledge.
