The Endura is equipped with a 42 channel GPS receiver. The antenna is located behind to the top Gummarmierung. Perhaps you once had problems with reception, because your caching, hiking or biking the Endura have only switched on in the forest. Perhaps he was even before shut for days. You had to then find that it takes quite a long time until such a position is displayed. This
you can display the Endura an accurate position, it must be calculated by triangulation based on the known satellite positions the current point on the earth's surface. GPS for us people the earth is not necessarily a misshapen ball planted and watered with beautiful mountains, but we regard them as ellipsoids. This simplifies our calculation considerably - especially because we know that the earth anything but a sphere. To come back to the Endura: The must of course know the positions of the satellite above the ellipsoid to calculate our position to be able to. The satellite in turn make our life a little hard to Endura. You are not always stationary at the same place (it's just not that easy a satellite to accelerate and steer, that he is almost on the ground), but they orbit on certain tracks, 2 times a day the earth. In order to show as quickly as possible after switching to a position, the Endura save the orbital data of satellites. We speak also of the so-called almanac. A satellite can fail temporarily, or not be visible, or the path data in the Endura are completely obsolete, because it was not long in operation. Maybe just a little green man kidnapped a satellite ;-) Anyway, it is always necessary to update the tracking data. Each satellite transmits this data, but it needs purely mathematically about 13 minutes to load all path data. Pending completion of this charge is used the Endura his old records and then upgraded step by step to a satellite at a time. On the status page, one can observe how the beams of the satellites are constantly resorted to a certain order is established. Move the beam in their order no more, the loading is completed. The Endura should have in this charging time visibility to the sky. Also note that the tracking data are often inaccurate even after 2 days. Before your loszieht therefore, give some time to warm up the Endura is. So turn on the best home already, and he has a stable reception - it is called also FIX.
