Principle


The VIGILANT is an on-board alert system allowing all road users to warn and to be warned anywhere, in real time, and progressively, at a range of one kilometre

FLARM is based on a concept of disseminating GPS-derived position data with a digital radio broadcast. This concept is as old as GPS itself and has often been discussed in detail and was further developed in several occasions. There exist many practical systems based on the same concept, e.g. ADS-B for optimized air traffic control or Vigilant, designed and developed by Jean-Marc Baggio. Vigilant is a car-based alert system patented in 1996 allowing all road users to warn others and to be warned. Vigilant prevents massive freeway pileup to happen and has caught the car-industry's attention. In 2001, Mr. Baggio extended his concept for air and sea safety under the name Proximetre. FLARM Technology acknowledges Mr Baggio's work and achievements, while Mr Baggio has agreed to support FLARM's further expansion into the French market, also by explicitly waiving potential intellectual property rights that may be used by FLARM Technology in aviation.
