# Overview

The JSS-LD-24-200 is a compact altimeter radar with high measurement accuracy, small size, high sensitivity, light weight, easy integration, stable performance, all-weather operation, and strong anti-interference capability. It is suitable for complex terrain, including vegetation, grassland, and water surfaces, enabling accurate altitude determination and terrain tracking.

### Features

* High sensing accuracy
* Great signal penetration with 24GHz FMCW millimeter wave technology
* Low side lobe antenna design to reduce interference
* Lightweight and low profile
* DroneCAN interface, compatible with Ardupilot and PX4<br>
