Got an intriguing question from a different department for all you GPS junkies. The OP in a different thread (here's the link, for those who might want the background: viewtopic.php?t=13805) wants to track freshwater turtles using a GPS/cellular combo. He chose the Telit GE-863-GPS, but it has power-hunger problems. After doing some preliminary engineering, the OP came across a tracker already being made by NavSys that uses an interesting trick for acquiring very fast GPS data. Instead of processing a full-blown fix and being "awake" for many seconds, it simply grabs a ~60mS "snapshot" of the satellites in view and saves or re-broadcasts that, rather than processing the data onboard. This of course results in huge battery savings.
The question is, does anyone know of a GPS or GPS/cell module that can do the same thing (or be "taught" to do it)?
