Local Hybrid Navigation System of Tethered High-Altitude Platform

This paper describes the principles of building the local navigation system for a tethered high-altitude platform. In particular, the platform ”Albatross” developed by the scientists of the Institute of Control Sciences of the Russian Academy of Sciences is considered here. The hybrid navigation system is proposed here. The system includes the millimeter and optical subsystems. The millimeter system effectively functions at altitudes above 5-10m, the optical system effectively functions at altitudes below 5-10m. Moreover, each of them can be used as a backup in the corresponding range.
