Mode 3/A is used to identify each aircraft in the radar's coverage area. Mode C is used to request/report an aircraft's altitude. Two other modes, mode 4 and mode S, are not considered part of the ATCRBS system, but they use the same transmit and receive hardware. Mode 4 is used by military aircraft for the Identification Friend or Foe (IFF ...
Various modes exist from Mode 1 to 5 for military use, to Mode A, B, C and D, and Mode S for civilian use. Only Mode C transponders report altitude. Busy airports usually require all aircraft entering their airspace to have a mode C transponder which can report altitude, due to their strict requirements for aircraft altitude spacing; this is ...
A traffic alert and collision avoidance system (TCAS), pronounced / ˈ t iː k æ s / TEE-kas), also known as an Airborne Collision Avoidance System (ACAS), [1] is an aircraft collision avoidance system designed to reduce the incidence of mid-air collision (MAC) between aircraft.
A GPS tracking unit, geotracking unit, satellite tracking unit, or simply tracker is a navigation device normally on a vehicle, asset, person or animal that uses satellite navigation to determine its movement and determine its WGS84 UTM geographic position (geotracking) to determine its location.

The rogue base station can send a 'Cipher Mode Settings' element (see GSM 04.08 Chapter 10.5.2.9) to the phone, with this element clearing the one bit that marks if encryption should be used. In such cases the phone display could indicate the use of an unsafe link—but the user interface software in most phones does not interrogate the handset ...
Air traffic control's ability to monitor aircraft was being rapidly outpaced by the growth of flight as a mode of travel. In an effort to improve aviation communication, navigation, surveillance, and air traffic management ICAO, standards for a future system were created. This integrated system is known as the Future Air Navigation System (FANS ...
Inter alia with Windows 10 and 8, this can be fixed by forcing the correct drivers to reload during Safe Mode. [9] In Windows 8, Windows 8.1 and Windows Server 2012, the controller driver has changed from msahci to storahci, [10] and the procedures to upgrade to the AHCI controller is similar to that of Windows 7.
