Undai for Satellite Communication
This antenna mount series was developed for rapid automatic direction adjustment, built with integrated GPS, tilt sensors, and a compass system. It features a polarization correction system that compensates the polarization angle for sloped terrain. We customize design and functionality to match on-site conditions and customer requirements.

We provide the accessories your communication equipment needs, and can develop or modify accessories to match your requirements (radomes, tripods, antenna brackets, camera housings, and more).
Map Integration Software
This software uses Geospatial Information Authority of Japan map data to verify and diagnose in advance how terrain may affect communication. It automatically generates a detailed elevation profile (cross-section) between two specified points, letting you quickly and visually confirm whether obstructions such as mountains or hills are present. It also calculates the precise distance and bearing between two points, and can instantly retrieve latitude, longitude, and elevation data at any point on the map — a powerful aid for optimal wireless-coverage area design and antenna direction adjustment.
