1. A method for GNSS compatible traffic management using a computer system incorporating zone incursion processing located on a vehicle including aircraft and surface vehicular equipment, said method comprising the steps of:

  • a. adopting a coordinate reference system for processing by said computer system, where said adopted coordinate reference system is the Earth Centered Earth Fixed coordinate reference;

    b. selecting a geographical region for said traffic management;

    said selected region being referenced to said adopted coordinate reference system;

    c. establishing a static zones database, for said selected region, said static zones database containing descriptive data representing selected spatial characteristics referenced to said adopted coordinate reference system;

    d. determining GNSS position data of said vehicle;

    e. establishing a vehicle database, said vehicle database containing said position data referenced to said adopted coordinate reference system;

    f. determining if said position data of said vehicle database incur a static zone, said static zone being defined within said static zones database; and

    g. enabling a static zone incursion flag for said vehicle if said position data incur said static zone of said static zones database thereby making a static zone incursion alert.
