IMPROVED GEO-TAGGING |
摘要 |
<p>A method of estimating the position of a first event of interest using a satellite positioning system. The method comprises: performing in response to the first event a satellite reception function; determining at some later time whether it is possible to calculate a position estimate from signals resulting from the satellite reception function; and, if not, estimating the position of the first event based on a position estimate of a second event, wherein the second event is that closest in time to the first for which a position estimate is available. Thus, the method can provide a position estimate for the first event even if the satellite reception function fails.</p> |
