Experiment results on test methods for detection and avoidance (DAA) systems for unmanned aircraft s...
This document provides a report on tests that were performed to ensure the "safety and quality" requirements of detection and avoidance (DAA) systems used between UASs and other objects, including aircraft. This document describes test methods and the results of related experiments, which successfully meet the requirements of a DAA system architecture with radar and optical sensors.

IEC 60875-1:2024 applies to non-wavelength-selective fibre optic branching devices, all exhibiting the following features:
- they are passive, in that they contain no optoelectronic or other transducing elements;
- they have three or more ports for either the entry or exit, or both, of optical power, and share optical power among these ports in a predetermined fashion;
- the ports are optical…
