Problems solved by technology

Since the functions and principles of the above-mentioned remote sensing devices are different, and the corresponding technical parameters are also different, the index requirements of each remote sensing device are different, so it is difficult to ensure that each remote sensing device is Remote sensing equipment can meet their respective index requirements, which leads to remote sensing aircraft needing to fly multiple routes and constantly change flight altitudes to make up for the differences caused by different index requirements, which will lead to redundancy in flight sorties, flight routes, and flight time. reduction in flight efficiency
