Abstract
A system for determining location and pointing angle to a selected one of a first series of orbiting satellites as provided, wherein information relating to the system and desired satellite, is provided the electronic signals emitted by a second series of orbiting satellites. System is hand-held, compact, and portable, and is adapted to work in any environment, being immune to magnetic deviations. The satellite locating and pointing system makes use of certain hardware configurations and mathematical algorithms to determine location, and elevation information with respect to both the user and the desired satellite. The mathematical algorithms are also adapted to reduce errors inherent in incoming information from said satellites.
