Abstract
Various methods, apparatuses, and systems for providing a delayed geotag using GPS devices are described. The GPS device includes a wireless receiver configured to receive satellite state data and satellite range measurements from a plurality of satellites, a communications interface in communication with a media device, and a position engine configured to calculate a geotag. The GPS device can be configured to receive satellite range measurements from one or more satellites at a first point in time when the satellite state data for a minimum number of the satellites is unavailable, and to calculate the satellite state data at that time using satellite state data received at a second, later point in time. The satellite state information at the first point in time is calculated using an algorithm to extrapolate the satellite state data back to the first point in time when the satellite range measurements were made. The GPS device can calculate a geotag using the calculated satellite state data at the first point in time and the corresponding satellite range measurements.
