Abstract
Systems and methods for determining a position of a global positioning system (GPS) receiver are provided. A first satellite and a second satellite that have an unobstructed communication path to the GPS receiver are identified. For each of the first and second satellites, data received is used to determine a satellite position and a code phase for a transmitted satellite signal. A relative code phase is calculated between the transmitted satellite signals of the first satellite and the second satellite, where the relative code phase is a difference between the determined code phases. The position of the GPS receiver is determined based on the satellite positions of the first and second satellite and the relative code phase.
