So our trip begins!
Peculiarities of the National GPS-navigation. Polar Urals
Exit from the car of a train with the romantic name "Moscow Labytnangy" and immediately understand that "here you are not here! Although, like, and the weather is nice, but pulling a breeze blows through. But the cold can not stop our leader - this fighter for the promotion of technical progress in the Far North. He immediately tries to bind the card into the Palm Vx to the coordinates of our real position. Standing in the cold, patiently waiting for the completion of the historic moment. We, too, for the progress! In general, ... Associated all-terrain vehicle, an unknown, but rather "prohodimistoy" design, gives us, as follows, to warm up walking and dovozit almost to the entrance to our valley - a point of departure. Vzmetnuv to the sky clouds of snow treads, he is hiding, but we are going to ski a bit further and get up on the first night.

About -20 and the wind. All are engaged in furnishing life, but our leader is only interested in the process of "binding of the second coordinate" in the Palm Vx, Cassiopeia E125 inspection work and GPS eTrex. It turns out it works! "Unexpected" is called. And even what we see on the paper map, and around, completely coincides with the instrument readings! Fall asleep, it is nice affected power of knowledge.

Conclusions of Day:

GPS for Palm Vx shows that he had found as many as 12 satellites for a long time to move to the small screen some numbers. Waiting for results is delayed, and in fact does not end. So it is not clear - the receiver has identified its location or not. To make sure that the satellite signals received clear and you can work on, you need to go to another application (NMEA Monitor), but it's not very convenient. Another subject - eTrex in conjunction with the Cassiopeia "savvy" is much faster: catch the satellite signals and then displays the accuracy of the coordinates.

True, Cassiopeia E-125 so far focused on the ground worse than us: the difference in determining the point on the map is about 800 meters. While the maximum precision of our measurements - 6m. This is probably due to the fact that the map for Cassiopeia had to cook on a desktop computer. The coordinates of the night:
