What is GPS? 1 What is GPS? GPS is a system of 24 satellites which circle the earth twice a day in a very pre- cise orbit and transmit information to earth. The GPS II + must continuously “see” at least three of these satellites to calculate your position and track your movement. By using an almanac (a timetable of satellite numbers and their o[...]

2 Satellite Acquisition Satellite Acquisition Because the GPS II + relies on satellite signals to pr ovide you with navigation guidance, the receiver needs to have an unobstructed, clear view of the sky for best performance. In a nutshell, the GPS receiver’ s view of the sky will generally deter- mine how fast you get a position fix—or if you g[...]

3 Battery Installation Battery Installation The GPS II + operates on 4 AA batteries (not included), which are installed at the base of the unit. These batteries provide up to 24 hours of use. T o install the batteries: 1. Flip up the metal ring at the base of the unit, and turn the ring 90˚ counter clockwise. 2. Install the batteries (Fig. 3), and[...]
