# Implementation of MUAV as reference source for GLAO systems

## TL;DR

This paper presents a method to use MUAVs as artificial reference sources for GLAO systems, analyzing turbulence profiles and establishing flight stability and altitude requirements for effective star emulation.

## Contribution

It introduces a novel approach to generate artificial guide stars using MUAVs, detailing the necessary flight parameters and demonstrating feasibility with commercial UAVs.

## Key findings

- MUAVs must be at least 800 m above the observatory.
- A stability of 1.54 cm is required in less than 18 ms.
- Commercial MUAVs can nearly meet these requirements.

## Abstract

We propose an alternative method to generate an artificial reference source for a Ground Layer Adaptive Optics system airborne on a Multirotor Unmanned Aerial Vehicle. Turbulence profiles from the Ground Layer at the National Astronomical Observatory in San Pedro Martir were analyzed to establish the requirements in luminosity, altitude, and flight stability of an artificial source. We found the source must be at least 800 m above the observatory's surface and follow a fixed trajectory to emulate the apparent movement of the stars with a stability of 1.54 cm in time intervals smaller than 18 ms. We establish some commercial and customized MUAVs can nearly accomplish this task.
