I'm looking for a micro GPS transmitter which doesn't require much battery. You know any?

Update:

I want to be able to see (on my smartphone) where my keys are.

There are *many* 'GPS key finders' on the market. However, they don't really have GPS. You can find the *last location* of your tracker, but if somebody takes your keys (or car, if you have tracker somewhere in your car), you can't see where they are. You can only see what the last position was, since your smartphone stores the location (via bluetooth) as long it is within 25m.

Update 2:

I found some GPS transmitters, but they are big and the battery is empty within 1 or a few days.

Probably because it sends its position very often. There's no need for that; once every 5 minutes a 'quick send' is enough. So the battery should not be empty within a month or so.

    No such thing outside of movie fiction.

    The only way one can be contacted at an unknown distance is if it contains a mobile phone (cellphone) style data system.

    That means it has the same "standby" limitations of a similar size phone - plus the GPS part is operating to monitor and record its position.

    The result is either a small unit that has a day or so battery life, or a "brick" that's got a massive battery in it. (Or one that needs connecting to external power to operate).

    Note that calling them "GPS Transmitters" is confusing, it's a GPS Receiver connected to a data logger and/or data modem of some sort.

    There is such a thing as a "broadcast" style unit, but that has similar size-vs-battery-life limits and needs a licence if the range is more than a few tens of metres. They send a beacon transmission every so often with the position in a data burst.

    [One form of long range device is an APRS beacon, which needs a ham radio licence to use; but they can be monitored from anywhere via internet gateways; power considerations as above, they are mostly vehicle-based or fixed stations].

    No such thing as a GPS transmitter, unless you talking about a repeater or the device on a satellite.
