Reviewer 2 Report

Obvious writing mistakes throughout the manuscript, e.g., Multi UAVs -> Multi-UAVs (l2), global positioning system GNSS (l47), vision SLAM method (l87), etc. 

References missing in the Introduction 

Organisation of the paper missing in the Introduction

Didn’t see the logical flow for some sections. For instance, how is it jumping from Section 2.1 to Section 3.1.1? Should Section 3.1.1 be Section 2.1.1? No linking connections at all. It is necessary to have some overall paragraphs in the beginning of each section and some conclusive paragraphs when you close the section. 

Figures: do you generate all figures yourselves or reuse them from somewhere else? If latter, please cite the papers. In Figure 13, your legend is not aligning with the curves. 

Sections 6 and 7 should be merged. You don't have references for these sections.

Round 2

Reviewer 2 Report

The authors have addressed my comments in the previous round. I don't have any other issues left. Overall I think the manuscript merits a publication in Drone for its current presence.
