Who We Are

The PASSUR Network


Global Gate-to-Gate Flight Tracking

Airlines need to track their flights anywhere in the world, but in order to do so, all commercial companies using the airspace depend on information from governments. At PASSUR, we augment and integrate government information with data from our independent network – the largest passive commercial radar network in the world.

  • Over 180 radar locations covering North America from coast to coast, and locations in Europe and Asia.
  • Faster aircraft position updates (from 1.0 to 4.6 seconds).
  • More complete information on aircraft.
  • Sensors receiving aircraft and drone signals in Modes A, C, S, and Automatic Dependent Surveillance-Broadcast (“ADS-B”).
  • Information on position, altitude, beacon code, tail number, etc.

In May 2015, PASSUR launched a new ground-based surface surveillance system to extend PASSUR coverage to runways and taxiways (“movement areas”) as well as ramps, alleyways, and throats (“non-movement areas”). PASSUR Surface Surveillance is a low-cost, effective way to introduce surface surveillance at an airport or extend coverage to areas that are not currently captured by an existing system.

  • Passive multilateration sensors generate real-time data on aircraft and vehicles moving on the airport’s surface.
  • Data is integrated with other existing surface surveillance systems to expand the surface management capabilities of the PITM suite.
  • PASSUR is ADS-B enabled and readily adaptable to the growing deployment of ADS-B equipped aircraft.

A combination of signals from aircraft in real time and information from our 10+year historical database of aircraft and airport behavior tells us more about how aircraft, the airspace, and airports have performed in the past and how they are performing currently, and allows us to predict how they are going to perform and, more importantly, how they should perform.
