Traditionally the best GPS for signal speed is a Garmin GPS. These are built with high quality materials and are traditionally more accurate when it comes to signal speed.

Well most tracking devices are plug into the vehicles diagnostics and sends reports back to the receiver which most likely will use a cellular signal to send that information to whomever installed it. There are some devices that are just hardmounted or fixed on the vehicle without being connected to the diagnostics computer and can be placed anywhere in or on the vehicle, then a gps signal is received from the device as that vehicle moves around.

DSP is also used in military. For Radar signal processing. For Sonar signal Processing. For Navigation and For Secure communications.
Emergency signaling devices work differently depending on what type they are. There are hand-held devices that will signal location services to emergency vehicles like police and fire. There are transmitters for air services that broadcast a distress signal. There is a beacon that ships use that transmits on radios.
Place emergency signal devices at least how many feet before scene of accident?
by broadcasting a radio signal. The signal is picked up by a minimum of 3 satellites, which by triangulation can determine where the signal is coming from.
Active devices are those devices which can produce power or which can amplify the signal Such devices are- diode transistor op-amp
