System for positioning and orienting an aircraft relative to a reference beacon using radio waves

This repository refers to the patent, System for positioning and orienting an aircraft relative to a reference beacon using radio waves, ES2734396 - P201800132 The invention consists of a system for positioning and orientation in three dimensions of an aircraft with respect to a reference beacon using radio waves, based on the calculation by a central processing unit or CPU of the delay differences between the signals entering the CPU. This invention overcomes the difficulty of measuring radio wave delays at close distances and for very short durations, thanks to the use of a pseudo-random code correlation technique that causes a slowing effect on these delays.
