person, in a bag or in a vehicle. The Reporter will give its position and
acquired equipment or personnel data on a timed basis or when requested
from a Control Centre. The precise location is calculated from the GSM
cellular network or GPS co-ordinates if available. Using highly integrated
efficient Controllers, the Reporter can operate for many months on a single
charge of the battery.
