Oh dear, you've perhaps fallen for the techo-babble. But you are in good
company.
"The Times" today utters the following complete drivel:
"The satellite can tell where a person has been during a given
period ... The device will send signals to the satellite
allowing the offender's movements to be monitored".
In case anyone is in any doubt, the "device" knows where it is by
comparing the signals transmitted from the transmit-only satellites (at
least half a dozen are typically required to be in view). It may then
reveal where it's been, but as the offender isn't carrying a kilowatt
transmitter and an auto-aligning two metre dish, that must be done via
something terrestrial like SMS, rather than beaming up to a (sic)
satellite.
