Small Radio Altimeter MY-28A、MY-24(XXX-28A、XXX-24)

The MY-28A and MY-24 (also designated as XXX-28A and XXX-24) are miniaturized C-band full-function radio altimeters that comply with aerospace standards. Serving as key components for the control of the longitudinal altitude channel, they are specifically designed for a certain type of UAV target. These altimeters possess excellent anti-interference performance and electromagnetic compatibility, enabling them to accurately measure altitude relative to the sea surface or the ground.
The MY-28A and MY-24 are developed following the three core design principles of serialization, standardization, and modularization. This design approach endows the products with strong design inheritance, ensuring they are mature and reliable in operation. To date, these two models of radio altimeters have been widely applied in multiple types of aircraft, with their total deployment quantity exceeding 800 units.
