Apparatus for monitoring aircraft position
First Claim
1. An apparatus for monitoring the position of one or more aircraft, comprising:
- a first receiver device that receives first aircraft position information, over a digital data link, from a first radio frequency source located onboard the aircraft at a first periodicity, via one or more ground stations;
a second receiver device that receives second aircraft position information broadcasted from a second radio frequency source located onboard the aircraft at a second periodicity, via one or more ground stations;
a buffer that receives the first and second aircraft position information from the first and second receiver devices respectively; and
a processor that;
receives and filters the buffered first and second aircraft position information based on relative positional accuracy and relative temporal accuracy of the first and second radio frequency sources such that a quantity of filtered position information data for a given aircraft is within a given limit for a given time period,smoothes the filtered aircraft position information, andoutputs the smoothed aircraft position information such that it can be overlaid onto electronic geographical mapping data.

Abstract
An apparatus and computerized method are provided for monitoring the positions of one or more aircraft. The apparatus comprises a first receiver configured to receive first aircraft position information, over a digital data link, from a first radio frequency source located onboard the aircraft at a first period, via one or more ground stations and a second receiver configured to receive second aircraft position information broadcasted from a second radio frequency source located onboard the aircraft at a second period, via one or more ground stations. The apparatus additionally comprises a third receiver configured to receive electronic geographical mapping data and a processor configured to receive the first and second aircraft position information, to filter the quantity of first and second aircraft position information to smooth the filtered information and then output the smoothed information such that it can be overlaid onto the electronic geographical mapping data.

16. A computerised method for monitoring the position of one or more aircraft, comprising:
-
receiving, at a first receiver device, first aircraft position information, over a digital data link, from a first radio frequency source located onboard the aircraft at a first periodicity, via one or more ground stations; receiving, at a second receiver device, second aircraft position information broadcasted from a second radio frequency source located onboard the aircraft at a second periodicity, via one or more ground stations; receiving, at a buffer, the received first and second aircraft position information; filtering, at a processor, the buffered first and second aircraft position information based on relative positional accuracy and relative temporal accuracy of the first and second radio frequency sources such that a quantity of filtered position information data for a given aircraft is within a given limit for a given time period; smoothing, at the processor, the filtered aircraft position information to produce smoothed aircraft position information; and outputting, from the processor, the smoothed aircraft position information such that it can be overlaid onto electronic geographical mapping data. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 33)

31. An apparatus for monitoring the position of an aircraft, comprising:
-
a first receiver device that receives aircraft position information corresponding to the aircraft; a second receiver device that receives a number of frames of weather data, each frame corresponding to a given moment in time; and a processor that; receives the aircraft position information and the weather data, derives aircraft position data for the aircraft corresponding to each moment in time represented by the frames of weather data, outputs the aircraft position information, the aircraft position data and the weather data such that it can be overlaid onto electronic geographical mapping data, and estimates, for frames of weather data corresponding to a future moment in time, the aircraft position data based on an extrapolation from a position and trajectory of the aircraft identified by the aircraft position information or based on an interpolation between a position of the aircraft identified by the aircraft position information and a flight plan corresponding to the aircraft received at the processor.
