Virtually every cellphone tracks its movements. Tracks can be map displayed in real time, using GPS tracking software and devices with GPS ...
These dual-frequency GPS receivers typically cost US$10,000 or more, but can have positioning errors on the order of one centimetre or less when used in carrier phase differential GPS mode.

The location data so derived is not as accurate as that from GPS or PTT (platform transmitter terminal) tracking involving satellites, but the devices can be made considerably lighter and cheaper. Other sensors, such as for recording temperature, or whether the logger is wet or dry, may be used in conjunction with the light-level logging in ...
