NS 10 Operations Manual
HOW THE NS 10 WORKS
There are two main components of the NS 10 navigational system: the receiver which mounts outside the cabin at a high, unobstructed point on your boat, and the NS 10 control head, which mounts on the console or at some other point convenient for use. The receiver and the NS 10 communicate by means of a coaxial cable, and are powered by your boat’s 12 volt electrical system or battery.
The receiver, when in clear view of the sky, receives transmissions from the constellation of GPS satellites which are continuously orbiting the earth. It selects four satellites whose position and signal strength will provide the most accurate position “fix”, and locks onto them. From these four satellites, the receiver is able to ascertain the time (accurate in thousanths of a second), the position of the boat in reference to Latitude and Longitude position (accurate to +/- 15 meters RMS with SA off), the boat’s speed and direction of travel. This information is updated once per second and sent to the NS 10 for display. The NS 10 uses this “raw” information to provide many options for graphic display. Your position is superimposed onto digital maps stored in the system’s memory.
