Abstract
Systems and methods to mitigate instrument landing system (ILS) overflight interference are disclosed. An example method performing a first measurement of a position of an aircraft relative to a first location based on an instrument landing system, performing a second measurement of the position of the aircraft based on inertial measurements performed over a first time period occurring prior to the first measurement, performing a third measurement of the position of the aircraft based on inertial measurements performed over a second time period greater than the first time period and occurring prior to the first measurement, and generating guidance information based on a selected one of the first, second, or third measurements of the position of the aircraft.
Claims20
A method, comprising:
- performing a first measurement of a position of an aircraft relative to a first location based on an instrument landing system;
- performing a second measurement of the position of the aircraft based on inertial measurements performed over a first time period occurring prior to the first measurement;
- performing a third measurement of the position of the aircraft based on inertial measurements performed over a second time period greater than the first time period and occurring prior to the first measurement;
- and
- generating guidance information based on a selected one of the first, second, or third measurements of the position of the aircraft.
An apparatus, comprising:
- an instrument landing system to perform a first measurement of a position of an aircraft relative to a first location;
- an inertial reference unit to perform inertial measurements of a change in location of the aircraft;
- and
- a position selector to select between the first measurement, a second measurement of the position of the aircraft based on the inertial measurements over a first time period occurring prior to the first measurement, and a third measurement of the position of the aircraft based on the inertial measurements performed over a second time period greater than the first time period and occurring prior to the first measurement, and to generate guidance information based on a selected one of the first, second, or third measurements of the position of the aircraft.
A computer readable storage medium comprising machine readable instructions which, when executed, cause a processor to:
- perform a first measurement of a position of an aircraft relative to a first location based on an instrument landing system;
- perform a second measurement of the position of the aircraft based on inertial measurements performed over a first time period occurring prior to the first measurement;
- perform a third measurement of the position of the aircraft based on inertial measurements performed over a second time period greater than the first time period and occurring prior to the first measurement;
- and
- generate guidance information based on a selected one of the first, second, or third measurements of the position of the aircraft.
