BTSTC-RA121

Details

Overview

BTSTC-RM121 can continuously and accurately measure the relative altitude of the carrier to the ground or sea surface, and can be widely used in aircraft landing system, helicopter altitude indicator instrument, ground tracking system for ultra-low altitude flight, etc. The radio altimeter adopts the advanced 32-bit ARM processor and the surface attached integrated circuit, which greatly reduces the volume and weight of the whole device, significantly reduces the failure rate of the product, and greatly improves the MTBF. At the same time, the table enhances the system self-check, setting, temperature compensation and other functions, which greatly enhances the practical type of equipment and the reliability and maintainability of the equipment.
