5The eXplorist 100 uses information from the GPS satellites orbiting the earth to provide youwith detailed information about your exact location. This is the foundation that youreXplorist will use to provide you with the necessary information to arrive at your destination.Going to a DestinationThe most common use of your eXplorist will be to provide you with the navigation toolsyou’ll need to arrive at your chosen destination. The simplest route, and the one usedmost, is a GOTO route. This is a route that is computed as a straight line from where youare to where you want to go.Step One: Compute Your PositionThe basic operation of your eXplorist is to use the GPS satellites to compute your pres-ent position. This is done internally in the software of your eXplorist. The only thingthat you need to do is to give your eXplorist a clear view of the sky so that it can receivethe signals from the satellites.Do:• Point the antenna up toward the sky.• Maintain a clear view of the sky.Don’t:• Cover the antenna with your hand or other objects.• Point the antenna down.• Stand under trees or other heavy foliage.• Stand where the satellite signals are being blocked by large obstructions (such asbuildings, in a narrow canyon, etc.)If you find that the eXplorist is not computing a position, just move to a place that hasa better view of the sky.Anytime that you want to view the status of the satellites andtheir signal strength, switch to the Satellite Status screen. Here,you will graphically see the satellites and their relative signalstrength. You need at least three satellites with good signalstrength (indicated by black bars) to compute your position. Acomputed position with only three satellites is termed a 2D posi-tion fix. When you are getting a 2D position fix, your elevation isnot being computed. To add elevation to your position fix, youneed at least four satellites with good signal strength. Positionsthat use four or more satellites are called 3D position fixes.3D Position FixTracking 7....Using the eXplorist 100
