某些特殊领域无人机需要实时得到精确的离地高度，GPS精度达不到要求。
随着无人机技术的逐步成熟，民用无人机在日常生活中已经得到了广泛的应用，近年来，我国民用无人机市场需求已经超过军用无人机。2017年我国无人机市场规模达121.3亿元，其中，军用无人机54.0亿元，民用无人机约67.3亿元。无人机市场在各个领域得到了广泛应用，除军事用途外，还包括农业植保、电力巡检、警用执法、地质勘探、环境监测、森林防火以及影视航拍等民用领域，且其适用领域还在迅速拓展中。
With the development of UAV technology, UAVs have been widely used in daily life. In recent years, the demand of UAVs in China has exceeded that of military UAVs. In 2017, China's drone market reached 12.13 billion yuan, including 5.40 billion yuan for military drones and 6.73 billion yuan for civilian drones.
The UAV market has been widely used in various fields. In addition to military use, it also includes civilian fields such as agricultural plant protection, power inspection, police law enforcement, Geological exploration, environmental monitoring, forest fire prevention, and film and television aerial photography. Its application field is still rapidly expanding.
物流无人机/Logistics UAV
搭载SK-Z系列单点测距激光雷达的物流无人机，可以实现定高功能（保持与地面相对高度），在保证货物和人员安全的高度下抛投，随后无人机可立即返回，无须停机再启航，减少起落油耗，节约成本。
Logistics drones equipped with SK-Z series single-point ranging Lidar can achieve high performance(maintain relative height to the ground), throw at the height of ensuring the safety of cargo and personnel, and then the drone can immediately return without stopping. Set sail, Reduce fuel consumption and save costs.
植保无人机/Plant Protection UAV
植保无人机需要进行仿地飞行，即保持与农作物维持1-2m的相对高度，且随着地形的变化，自动调整姿态。搭载SK-Z系列单点测距激光雷达的植保无人机，可以实现仿地飞行，保障农药被均匀且高效喷射。
The plant protection drone needs to fly on the ground, that is, maintain a relative height of 1-2 M with the crop, and automatically adjust the posture as the terrain changes. Plant protection drones equipped with SK-Z series single-point ranging Lidar can achieve ground flight and ensure that pesticides are evenly and efficiently sprayed.
