2. ATM Automation System and Advanced Surface Movement Guidance and Control System(ASMGCS)
- Providing guidance, surveillance and Control Support to the Air Traffic Controller
- Maintaining aircraft movement rate under all local weather conditions
- Improving the safety in airport traffic especially during low visibility and night operations
- Reducing taxiing times and scheduling more efficiently.
- Conflict free continuous taxiing
Air Traffic Management (ATM) provides automated assistance to ATC personnel by performing following Main functions:
- Acquisition, Collection, Processing, Integration, Distribution and Presentation of Multi-Sensor Surveillance data, Flight Plan data, and Meteorological and Aeronautical information.
- Data exchange with Adjacent ATS units, Aircraft on-board system, and other internal and external systems and agencies
- Alert capabilities through flight monitoring and prediction functions
- Technical Monitoring and Control of the system, and management of operational parameters and environmental data.
- Recording of surveillance and flight data, meteorological and aeronautical information and user inputs for subsequent playback and analysis purposes
3. Indigenous ATC Radar
BEL indigenously developed Airport Surveillance Radar (ASR) is a S Band Radar (2.7 to 2.9 GHz) co-mounted with L band Monopulse Secondary Surveillance Radar (MSSR) for seamless Air Traffic Control application with detectable range of 60 NM (ASR)/250 NM (MSSR) in 360 deg Azimuth.

4. MLAT SYSTEM
MLAT (Multilateration) is a cooperative system for targets surveillance and identification in airport environment. MLAT system uses differential Multilateration techniques or Time Difference of Arrival (TDOA) principle, in order to estimate the exact position of targets having Mode-S and Mode 3/A & C transponders. Targets identification is also possible by means of ground station interrogation.
5. ADSB SYSTEM
Automatic Dependent Surveillance—Broadcast (ADS–B) is a surveillance technology in which an aircraft determines its position via satellite navigation and periodically broadcasts it, enabling it to be tracked. The information can be received by Air Traffic Control (ATC) ground stations as a replacement for secondary surveillance radar, as no interrogation signal is needed from the ground. It can also be received by other aircraft to provide situational awareness and allow self-separation.
ADSB is a Next Generation technology for Air Traffic Management, which requires no transmission provides 360deg coverage. ADS–B is “automatic” in that it requires no pilot or external input. It is “dependent” in that it depends on data from the aircraft’s navigation system.
