GPS receivers have a concept of an "ephemeris", which is basically the orbits of the GPS satellites in view and information about them. It uses this for a "warm start", so once it gets the signal from a single satellite, it can use that to get the current time, and then use that with the ephemeris to figure out where to look for other satellites. However, if it's been off for a while, the ephemeris will be out of date, so it has to do a "cold start" and work out everything from first principles. This takes a varying amount of time, depending on algorithms, antenna type, positioning, and sensitivity, the current arrangement of the satellites, and (of course) signal strength. While yours is one of the longer ones, it's not unheard-of. - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
