The traditional design of environment monitoring system is based on cable transmission, with the disadvantages of deployment difficulty, high costs, poor stability and accuracy.
While autonomous multirotor micro aerial vehicles (MAVs) are uniquely well suited for certain types of missions benefiting from stationary flight capabilities, their more widespread usage still faces many hurdles, due in particular to their limited range and the difficulty of fully automating the deployment and retrieval.
In most of the cases, the result-producing applications cannot be used because of difficulties in deployment and execution procedures.
