应该是有的,看来是失效了。Big bless.

How it works[edit]
GPS aircraft tracking solution needs a device embedded in the aircraft and
made of a GPS sensor. It transmits in real time or not the GPS position
received on board to a server on ground via a communication network. The
server collects the data. Data received on ground can be recorded and/or
used to display the aircraft real time position. Different kinds of
communication networks are used to transmit data on ground:
ACARS network which is a hybrid of VHF, Satellite and HF networks
Transponder "Mode S" (ADS-B) network
Satellite network (Globalstar, Immarsat, IRIDIUM, Thuraya)
GSM network
Device embedded in the aircraft may be avionics components like for ACARS or
ADS-B solutions. In these cases, antenna are located outside of the
airframe.
When device are not avionics components they have to be independent from the
aircraft. They are located within the aircraft and the GPS signal from GPS
satellites must be able to go through the aircraft airframe like for example
the cockpit window. The output signal must also be able to go through the
aircraft.
GSM network does not permit real time transmission in some countries due to
GSM transmission restrictions regulations.[1]
Benefits[edit]
One the goal of ADS-B solution is to reduce airspace separation for airline
aircraft by offering a more accurate situation description for the air
traffic controller.
ACARS solution is used by airline companies to track their airliners fleet.
Safety: GPS Aircraft Tracking permits to locate more easily an aircraft in
case of accident.
Automatic data processing, particularly to get OOOI events and to compute
flight time.
In general aviation, GPS Aircraft Tracking permits to follow a trainee and
to debrief his flight path after a flight.

gps是被动得,飞机出事,自己就不能发射所在位置了。
