    Объектом исследования является способ корректировки местоположения, при инерциальной навигации мобильного робота на местности в условиях отсутствия/искажения сигнала ГЛОНАСС/GPS, для работы на Крайнем Севере. Цель работы–разработка способа наземной корректировки навигации мобильного робота в условиях Крайнего Севера. В процессе исследования была изучена литература по тематике навигации мобильных роботов, в частности SLAM, судовой навигации, построения маршрутов, и видам алгоритмов, библиотек компьютерного зрения. В результате исследования была разработана структурная схема, был сделан подбор устройств в соответствии с необходимым функционалом, был разработан алгоритм работы системы и написаны соответствующие программы. Область применения: дорожные эксплуатационные предприятия.The object of the study is a way to correct the location, with inertial navigation of a mobile robot on the ground in the absence / distortion of the GLONASS / GPS signal, to work in the Far North. The purpose of the work is to develop a method for ground-based navigation correction of a mobile robot in the Far North. During the study, literature was studied on the topics of navigation of mobile robots, in particular SLAM, ship navigation, route building, and types of algorithms, computer vision libraries. As a result of the study, a block diagram was developed, a selection of devices was made in accordance with the necessary functionality, an algorithm for the operation of the system was developed, and corresponding programs were written. Scope: road operating enterprises

    Soil moisture and matric potential - An open field comparison of sensor systems

    No full text
    Soil water content and matric potential are central hydrological state variables. A large variety of automated probes and sensor systems for state monitoring exists and is frequently applied. Most studies solely rely on the calibration by the manufacturers. Until now, there is no commonly agreed calibration procedure. Moreover, several believes about the capabilities and reliabilities of specific sensing methods or sensor systems exist and compete. A consortium of several institutions conducted a comparison study of currently available sensor systems for soil moisture and matric potential under field conditions. All probes have been installed in 0.2 m depth under best practise procedure. We present the setup and the recorded data of 58 probes of 15 different systems measuring soil moisture and 50 probes of 14 different systems for matric potential, which have been used during the campaign in 2016. The data is extended by pedophysical analyses of the soil and laboratory reference measurements for calibration
