Provide equipment required for centimeter precision positioning. For position measurement of automobiles / construction machines / agricultural machines
This product corresponds to GPS and GLONASS and does centimeter precision positioning using RTK (real time kinematic).
It includes software such as base stations fixed in the field, mobile stations installed in vehicles, antennas and correction signal transceivers and viewer applications.
In software, it is possible to display real-time display of satellite capture status, radio (Zigbee) RTK correction data acquisition status, and facilitate investigation and construction of measurement environment. It also comes with a viewer that displays measurement data on a map (open street map) and displays it three-dimensionally. Correction data for RTK corresponds to delivery by wireless (Zigbee) and distribution via the Internet using Android terminal. A flexible system can be constructed according to the experimental environment. Correction data can be shared within a radius of about 5 km, so it is possible to measure the position of multiple vehicles and moving objects in the work field. It can be used in experiments such as vehicle running tests in test courses, high precision position measuring systems of moving bodies such as agricultural machines, construction machines, mobile robots, etc.
