Almanac screen
The Magellan NAV 1000 was the first handheld GPS ever built. The GPS-system was not even ready for full time coverage. Thus the NAV 1000 had a satellite schedule function. The user could check if there would be a 2D or 3D positioning possible at a specific time and place. The NAV 1000 has a wake up feature to switch on automatically for taking a position fix. This was useful when satellites were only available at night.
The NAV 1000 is meant to be a marine navigation tool. The functions are very basic. A text display with a few symbols is showing plain navigation data. 100 waypoints can be stored in the memory. There is only one active route possible.
The NAV 1000 is a single channel receiver. Data is received from one satellite, then from another and so on. It is very interesting to watch a NAV 1000 initializing. First the satellite almanac has to be loaded. A satellite can be chosen or the receiver will search one. After an initial position has been entered the NAV 1000 searches for satellites, one after another. Then it will receive data, one after another. Then "computing" is displayed for a while and with luck a position is calculated. After the initial fix the position is updated every few seconds.
The antenna of the NAV 1000 cannot be removed. For using an external antenna an antenna coupler was available.
