I am looking to buy a tracker which when there is no GPRS will store its GPS fixes until GPRS is available again and then send them. It is for a vehicle, so will have power supply and prefer internal aerials. Can anyone point me in the right direction?
Yes i can help u.
I would like a few actual suggestions of GPS trackers which can do this! I bought a cheap GT02 but it doesn't store GPS fixes when it cannot transmit via GPRS.
Here is a list of protocols that support this feature:
Some other protocol might support it as well, but they don't mark positions to distinguish between live data and saved.
