Position measurement of moving objects using a robotic total station
Horeličan, Tomáš ; Žalud, Luděk (oponent) ; Jílek, Tomáš (vedoucí práce)
This thesis deals with an emerging unconventional use case for modern theodolites, also known as Robotic Total Stations (RTSs), as a tracking and guidance system, by measuring the precise position of a dynamically moving object. This applies especially to situations where conventional positioning systems such as GNSS are insufficient or completely unavailable. A kinematically acquired position from a constantly tracking RTS could be used for real-time autonomous navigation of small Unmanned Aerial Vehicles (UAVs), essentially providing them with a reference coordinate frame and an immediate position within it. A significant part of this thesis is dedicated to the design and realization of suitable experiments, which would estimate the reliability of this precise position measurement in a precise moment in time. The S7 and S9 series stations from the Trimble company were evaluated and an S9 HP RTS, which provides a continuous measuring frequency of up to 10 Hz was then predominantly used for experiments. The local time of a TSC7 controller, interfacing with the RTS, was being synchronized through Precision Time Protocol (PTP) with the local time of a Raspberry Pi mini-computer, which then provided a reference measurement of an object's true position in time. The conclusion summarizes all obtained results.
