A study of accuracy using Novatel Flexpak GPS receiver

Abstract

Global Positioning System (GPS) allows properly equipped users to determine their position based on the measured pseudoranges to at least four satellites. By analyzing signals from the satellites, a receiver on the surface of Earth with built in microprocessor can display the location of the receiver in terms of latitude, longitude and altitude. GPS satellites are gradually revolutionizing driving, flying, hiking, exploring, rescuing and also map making. The accuracy and precision are the most important elements in GPS and also in this project. Few methods are known to improve the accuracy and also to investigate how accurate the receiver is.
