My GPS takes a little while to "warm up" before giving readings. On some days it is really quick and other days it can take about nearly 5 minutes. I would like to know what happens during this warm up time. Does it mean actual warming , as in temperature stability? Or does it refer to the electronics becoming stable ? Or does it mean that it is taking time to get reliable satelite readings?

The first thing your GPS receiver will do when switched on is look for as many satellite signals as possible to get a lock on your location. The more signals, the more accurate the unit will be.

The GPS satellites also transmit what they call a 'look up table' for the positions of each individual satellite for the course of a month or so. If the GPS receiver hasn't been switched on for a while, the information needs to be replaced with the new 'look up table' from the satellite. This, on some models, can take up to 12 minutes.

You can help reduce the time taken for this by making sure the antenna is looking into the sky correctly. Your instruction manual should have some info on this.

mine dose the same mate, mine is a holox receiver, it is looking for a different satellite, as they are constantly moving as do we, it sometimes has to use a different one it is logging onto the network. also when cold they acclimatise themselves so the circuits don't fry.
