HATS / Helicopter Tracking System

-A +A

Low altitude aircrafts in VFR flight such as helicopters are not trackable by RADAR systems. Fatal helicopter crashes in the past have underlined the need to track and locate such low altitude flights. The Helicopter Tracking System (HATS), which was developed with the the General Directorate Of State Airports Authority (DHMİ), is expected to aid in the quick determination of aircraft’s exact location after accidents.


  • Uninterrupted data acquisition, processing and recording
  • An extendible server architecture with back-up features
    • Double back-up server stack
    •  Data storing with back-up
    •  Double back-up firewall
    •  Back-up network and power connections
  • Secure Access through intranet with defined user/client authorization
  • Desktop clients supported by high performance geographical information system and vector maps
  • Authorized continuous tracking and retrospective querying capability
  • Authority groups and aircraft groups determination capability
  • Push-to-t alk (PTT) voice communications with aircrafts
  • Automatic Emergency Declaration for loss of communications with an aircraft
  • Declaration of emergency status with SMS and e-Mail


The Helicopter Tracking System consists of an Helicopter Tracking Device (HATC) fitted to the aircraft, and a Helicopter Tracking Center (HATM) on ground. Aircraft location, speed and altitude data is periodically transmitted to the monitoring center where it is displayed on a map. Aircraft in distress are highlighted on the monitoring center map display and an audio warning is sounded. Voice communication between aircraft unit and the monitoring center using a “push-to-talk” interface is made possible over GPRS.

As both GSM and satellite links are used for communications, system is both cost effective and reliable. Even if the aircraft unit discontinues functioning after a crash, the last reported location will greatly help search and rescue efforts.
