Embodiment Construction

[0057] Various embodiments describe embedding high-fidelity trajectory definitions within low-fidelity and standard trajectory definitions.

[0058] figure 1 Shows how full AIDL trajectory definitions can be embedded in Low Fidelity (LOFI) standard trajectory definitions 108 and exchanged by old / current communication systems using data communication links 109 that only support these standards as an exchange format.

[0059] Operators 107 (eg, pilots, air traffic controllers, and designated UAS operators) typically work on the basis of LOFI trajectory definitions 108 (flight plans), which typically do not explicitly determine AV motion.

[0060] In most cases, the LOFI standard trajectory definition 108 can be expressed as and maps directly to the concept of "flight intent" 105 . Typically, flight intent 105 contains trajectory-related information that does not necessarily uniquely determine AV motion, but instead typically incorporates certain aspects that define the AV's com...

Abstract

A computer-implemented method and a system for communicating high fidelity (HIFI) trajectory-related information of an aerial vehicle (AV) through standard aircraft trajectory conventions is disclosed. The method comprises the steps of: obtaining, from a first entity, a flight intent (300) containing low fidelity (LOFI) trajectory-related information; obtaining intent generation (IG) configurationparameters (301) defining constraints and / or objectives supplementary to the flight intent (300), containing HIFI trajectory-related information for closing all degrees of freedom of the AV's motionand configuration; encoding, using standard aircraft trajectory conventions, LOFI trajectory-related information from the flight intent (300) and IG configuration parameters (301) as a flight plan (305) and user-defined fields (306) available for information exchange; sending, to a second entity, the flight plan (305) and user-defined fields (306).

Description

technical field [0001] The present invention generally teaches techniques involving the exchange of detailed trajectory-related information expressed using a formal language through standard trajectory methods. Background technique [0002] Aircraft intent, expressed in a formal language also known as Aircraft Intent Description Language (AIDL), provides an unambiguous description of the intended motion and configuration of the aircraft during a flight session. The aircraft intent description is usually derived from the flight intent. [0003] Flight intent contains more fundamental information about how the aircraft will fly and does not provide sufficient information to allow an unambiguous determination of the aircraft's trajectory. Flight intent may be considered a generalization of the concept of flight planning, and as such will reflect operational constraints and goals, such as intended or required routes and operator preferences. In general, the flight intent will ...
