UNDERSTANDING HOW THE
I-PILOT SYSTEM WORKS
Navigation
i-Pilot uses GPS satellite signals as well as digital compass data to know where
it is, where it is heading and the direction the motor is pointing. Since
i-Pilot depends on GPS satellite signals for navigation, a minimum GPS signal
level of one bar is required in order for GPS navigation controls to be
enabled. Best results are achieved when a GPS signal level of four bars can
be obtained.
In simple terms, i-Pilot remembers and creates points to navigate your boat
automatically. i-Pilot also uses a method of GPS navigation called arrival
circles. These imaginary circles allow i-Pilot to understand when it has drifted
away from a point and when it has arrived at a point. The size of the
arrival circles vary depending on GPS signal strength, thus the greater the
signal strength the smaller the arrival circles.
Tracks
Tracks are made of many points that i-Pilot records when recording a track.
The distance between these points varies based on GPS signal strength and the
speed at which you record the track. When a track is played back, i-Pilot uses
the track points and arrival circles to navigate the track.
