    GPS satellite and use this information to compute your position. Your GPS receiver can only see satellites above the horizon, so it needs to know what satellites to look for at any given time. To use this almanac data, your GPS needs to either be told its general location or given the opportunity to find itself, or “initialize.”...

  • Page 8: Satellite Acquisition

    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 get a fix at all. GPS signals are rela- tively weak and do not travel through rocks, buildings, people, metal, or heavy tree cover, so remember to keep a clear view of the sky at all times for best performance.

  • Page 9: 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. To install the batteries: 1. Flip up the metal ring at the base of the unit, and turn the ring 90˚ counter clockwise. 2.
