Equipment for satellite navigation

Purpose

The ASN equipment for satellite navigation is designed to determine current coordinates, altitude, speed and time using satellite navigation signals of GLONASS, GPS, GALILEO, QZSS, SBAS (WAAS, EGNOS, GAGAN) systems within L1 band as a part of control systems for highly dynamic objects.

Application

Control systems for highly dynamic objects.
