Embodiment Construction

[0043]One or more currently preferred embodiments have been described by way of example. It will be apparent to persons skilled in the art that a number of variations and modifications can be made without departing from the scope of the invention as defined in the claims.

[0044]As explained above, there is a need for an improved system and method for allocating resources in a satellite system with flexible resources serving a large number of customers, both stationary and mobile. The Resource Deployment Optimizer of the invention provides a solution to this problem, determining the allocation of satellite resources in real time, and communicating this allocation throughout the entire satellite constellation and the ground network.

[0045]In the preferred embodiment the Resource Deployment Optimizer 100 includes the following components as shown in FIG. 1:[0046]Demand Grid Generator 105[0047]Link Budget Recipe Interpreter 110[0048]Constellation Linearizer 115[0049]Satellite Resource and...

Abstract

Systems, methods and techniques are presented for discovering optimal solutions to satisfy communication traffic demands to a NGSO and GSO satellite constellations used for telecommunication. When multiple ground demands (mobile and stationary) are present, a satellite constellation requires an assignment of satellite resources to optimally match the ground demands. The systems, methods and techniques presented can utilize an optimization structure to maximize the objective function, using linear programming in combination with simulation and predictive features. The techniques presented determine optimal or quasi-optimal allocation of scarce and highly constrained satellite resources in an efficient manner. These techniques take into account maximizing capacity while protecting other geostationary and non-geostationary networks.

Description

FIELD OF INVENTION[0001]The present invention relates to satellite systems and more particularly, to the provision of a novel, system and method for characterizing and allocating resources in a satellite communications system serving a plurality of users, stationary or mobile, or any combination of stationary and mobile users.BACKGROUND OF THE INVENTION[0002]Communication networks exist which include one or more satellites in Earth orbit, including satellites in non-geostationary orbit (NGSO). NGSO satellites may be in low Earth orbit (LEO) or medium Earth orbit (MEO). In some cases, a network may include satellites in two or more different types of Earth orbits, including networks with satellites in both GSO and NGSO orbits. Satellites may have a number of antennas (or antenna arrays) arranged to direct one or multiple beams over a coverage area. Satellites typically employ a number of radio wave frequencies or frequency bands so they can communicate through multiple channels at th...
