Abstract
Apparatuses, methods, and systems of transferring correction information are described. In certain implementations, correction factors relate to stored or calculated values, and a correspondence between a correction factor and a value is indicated by a predetermined order of the correction factors. In one application, a method according to an embodiment of the invention is used to transmit correction factors relating to the positions of physical objects. For example, such a method may be used to transmit correction factors relating to the positions of space vehicles within a Global Positioning Satellite (‘GPS’) system.
Claims54
A method comprising:
- calculating a plurality of correction factors, each correction factor relating to a position of at least a corresponding one among a set of physical objects;
- and
- transmitting said plurality of correction factors in a predetermined order, wherein said correspondence of each among said plurality of correction factors with at least one among the set of physical objects is indicated at least in part by said predetermined order;
- wherein said calculating a plurality of correction factors comprises:
- computing a reference position of each among the set of physical objects;
- and
- computing a supplemental position of each among the set of physical objects, wherein each among said correction factors is based at least in part on a difference between said corresponding reference and supplemental positions.
