Introduction

This document is aimed at the non-uniform coordinate projection and format of the three-dimensional spatial position information of civil unmanned aircraft and the insufficient expression of spatial range.

In order to solve the problems of low efficiency of position calculation, it stipulates the unified compilation of the three-dimensional spatial position information of civil unmanned aircraft based on the earth's subdivision grid.

Coding methods, including low-altitude three-dimensional grid division framework, grid size regulations for various types of civil unmanned aircraft corresponding to time and space ranges, civil unmanned aerial vehicle

Grid coding conversion method for three-dimensional space coordinates of human-piloted aircraft, three-dimensional space position coding format for civil unmanned aircraft, etc., covering

All aspects of the entire life cycle of civil unmanned aircraft, including production, user management, airspace management, and flight management, effectively improve the performance of civil unmanned aircraft.

Three-dimensional spatial location information in applications such as piloting aircraft equipment management, flight monitoring, collision detection, flight path planning, airspace control, service assurance, etc.

Civilian unmanned aircraft system identification

Three-dimensional space position identification encoding

1 Scope

GB/T 43551-2023 covers the coding used to state where a civil unmanned aircraft is, in three dimensions, at each stage of its life. The scheme joins a spatial position code to a time code, built on a grid code taken from a subdivision of the earth into low altitude cells, with the cell level chosen to suit the class of aircraft and the object being described. Four codes are then defined on that base: the production location of the aircraft, the location where its user keeps it, the real time position reported for flight management, and the position points that make up a mission trajectory. Clauses 3 and 4 settle the terms and the abbreviations that go with them. Position data for drones arrives in mixed projections and formats, and a spatial extent — a corridor, a no-fly volume, a delivery zone — is awkward to express as a point at all. Asking which aircraft are inside a given volume then costs far more computation than it should, at exactly the moment the answer is needed. A grid code turns those questions into comparisons between strings. For aircraft and flight control system makers, operators of unmanned traffic management platforms, and the authorities registering and supervising low altitude flight.

This document stipulates the location identification code for the production location of civil unmanned aircraft, the identification code for the storage location of unmanned aircraft user,

Flight management real-time location identification coding, flight mission trajectory location identification coding.

This document is applicable to the management and application of civil unmanned aircraft location information, as well as the identification, transmission and big data of spatial location information.
