Compact laser altimeter dedicated to drone ballistic carriers

In this paper, we report the results of investigations on the drone ballistic carriers being developed by our research team and we address specifically the concept of compact laser altimeter dedicated to the ballistic carriers. One of the main challenges facing the implementation of the mortar launched altimeter is to ensure its reliable operation after extremely high launch shock accelerations. This requirement determines the optical concept and materials selection and optimization. Recent mortar gun tests demonstrated that the optical and electronic sub-systems of the first altimeter prototype can withstand launch accelerations of at least 5000g.
