ANPC provides airspace safety, efficiency, and capacity to users of aviation through state-of-the-art tracking and guidance.

The company was founded in 1991 to benefit general aviation and expand overall airspace capacity by providing all-weather approach and landing capabilities to regional and municipal airports surrounded by rugged terrain or obstacles, beneath or adjacent to a runway’s final approach path.


1.      Transponder Landing System (TLS)  

The Instrument Landing System (ILS) has provided this capability to larger commercial airports for over forty years, but cannot provide sufficient guidance accuracy where reflections from obstacles interfere with its radio transmissions. Thus, ANPC’s founders developed the Transponder Landing System (TLS), a ground-based guidance system capable of supplying vertical and horizontal approach guidance to terrain-challenged airports, while at the same time utilizing ILS airborne equipment to minimize operator costs. ANPC is a transponder multilateration pioneer having deployed the first ground-based bi-static radar in 1991. TLS benefits from the best combination of time-of-arrival multilateration and phase measurement (interferometer) technology, with an ILS uplink to provide a combination of radar, ILS and PAR functionality that is extraordinary and unmatched in the world.

2.      Local Area Multilateration System (LAMS)  

During 2009 the LAMS (Local Area Multilateration System) product line was established. It derives from the surveillance components of TLS.

LAMS has the smallest footprint of any multilateration system because LAMS uses a combination of time of arrival and angle of arrival measurements for each aircraft transponder.

 Main LAMS application is Terminal area surveillance for ATC to monitor the approach and provide radar control services

  • Tactical ATC solution for expeditionary forces;
  • Quickly deployable for disaster recovery and emergency services;
  • parallel runway monitoring;
  • Runway anti incursion

In a transportable configuration, the LAMS is a highly mobile, rugged, and quickly deployable ATC solution for expeditionary forces during contingency operations. LAMS can be deployed by first time technician trainees and made operational in less than 2 hours.
