175 Manual 7/31/98 3:55 PM Page 5 GETTING STARTED 1 Acquiring Satellite Signals Acquiring Satellite Signals Because the GPSMAP 175 relies on satellite signals to provide you with navigation guidance, the receiver needs to have an unobstructed, clear view of the sky for best performance. What exactly does this mean? In a nutshell, the GPS receiver’s view of the sky will generally determine how fast you get a position fix, or if you get a fix at all. GPS signals are relatively weak, and do not t

175 Manual 7/31/98 3:55 PM Page 6 INTRODUCTION 2 Initialization Initializing Your GPSMAP 175 for First-Time Use Your GPSMAP 175 calculates your position and movement by tracking signals sent from GPS satellites. Each of the 24 GPS satellites circle the earth twice a day in a very precise orbit, and transmit information back to earth. In order to determine a position fix, your GPS receiver needs to continuously “see” at least three satellites. Because a GPS receiver can only see satellites abov

175 Manual 7/31/98 3:55 PM Page 7 GETTING STARTED 1 Initialization The first time you power up your new GPSMAP 175 is an important step in getting the best possible GPS performance. The receiver must be given an opportunity to collect satellite data and establish its present position. To ensure proper initialization, the GPSMAP 175 is shipped from the factory in AutoLocate mode, which will allow the receiver to ‘find itself’ anywhere in the world. To speed up the initialization process, we rec
