Abstract
In a method and system for performing location determination using multi-beam satellites each beam of a multi-beam satellite transmits identification information which is received by a user terminal. This identification information either identifies the unique beam by enumeration or by geometrics. A user terminal processes multiple received signals from orbiting satellites. The user terminal maps the projected beam patterns of multiple received samples to determine an approximate self-location. The user terminal passively monitors its location and compares its current location with its previously reported location. When the user terminal has sufficiently roamed from its previously registered location, the user terminal performs an auto-registration to the system allowing for efficient routing of information.
