Abstract—The design of human-machine interface for devices that determine possible positions using Global Navigation Satellite Systems (GNSS) is the topic of this paper. The aim of this work is to simplify the existing complicated mechanism of setting of these devices and to allow their full utilization for naive users as well. The mathematical model of surveying process was developed within an analysis. The design of interface is based on the theory of state machine with hierarchical states. The proposal is implemented by a system top-down analysis and links between the functional sub-components are described using a sequential scheme. The specific application for communication of the user with the interface was developed in this project. The application works in the off-line mode. That means all values of the parameters are imported into the device manually. The application works with the support of geographical information system that evaluates all spatial parameters and simulates the measurement conditions in the given locality. The design of interface was verified on the specific GNSS device, GRS-1 by Topcon Company.
