Communication
Communication is the process of sending, receiving and processing of information by electronic means.
Radio communication employs the electromagnetic waves for carrying information from one place to another. Radio communication systems have been classified depending on the frequency of the electromagnetic waves used for communication.
The electromagnetic frequencies used for communication have been classified into several bands based on frequency.
Security
Security System
The main objectives of the Security system are as follows:
Prevent attacks on airports or aircrafts.
Prevents accidents & fatalities due to transport of hazardous materials.
To ensure safety & security of passengers.
5.1 Security Equipments
The main security equipments are-
X-BIS
Metal Detectors
CCTV
ETDS
Navigation
Navigation is the ART of determining the position of an aircraft over earth’s surface and guiding its process from one place to another.
Radio Navigation is based on the use of Radio Transmitter, Radio Receiver and propagation of electromagnetic waves to find navigational parameter such as direction, distance, position of the aircraft etc.
According to service range the radio navigational aids are broadly classified into three categories –
1. Long Range.
2. Medium Range.
3. Short range
Localizer
Basically the localizer provides the centerline of the runway.
Localizer uses the frequency range 108-112MHz.
Its frequency at Jaipur Airport is 109.9MHz.
Log Periodic antenna is used.
Horizontal covering range for Localizer is 25NM.
The localizer unit consists of an equipment building, the transmitting equipment, a platform, the antennas and field detectors.
