1. A mobile device comprising:
a receiver to receive RF signals; a memory; and a special purpose computing device adapted to operate in an RF environment to: process information, represented by first signals, obtained in a first time period to obtain one or more measurements associated with said first time period; store unprocessed information obtained in said first time period; compute an estimate and/or a prediction of a state following said first time period based, at least in part, on said one or more measurements, wherein said state comprises a position and/or trajectory; obtain additional information, represented by second signals, subsequent to said first time period; re-process at least a portion of said stored unprocessed information obtained in said first time period combined with said additional information obtained subsequent to said first time period to obtain updates to said one or more measurements associated with said first time period; and re-compute said estimate and/or prediction of said state that was estimated and/or predicted based on the one or more measurements obtained in the first time period based, at least in part, on said updates obtained by the re-processing of the stored unprocessed information obtained in said first time period combined with said additional information obtained subsequent to said first time period. |
