Hardware - Xuanzang DY-SU6
Double flight control + six rotors, everything is designed for flight safety, with camera operation time of up to one hour, with two-axis head.
Why choose high-precision aerial rotary wing UAV:Reason 1: Strong wind resistance, not only the top wind operation, the aircraft is equipped with a two-axis pan/tilt, and with the rotor-winding wind-proof method, it can take an orthophoto similar to a manned aircraft under a large wind.
Reason 2: The turning radius of the rotorcraft can be neglected, so the equidistant photographing can keep the upper and lower navigation belts strictly aligned. The photo quality as shown in the following figure can greatly improve the matching accuracy of the empty three and the available range of the vertical measurement and the accuracy of the joint.
Reason 3: Takeoff and landing are not subject to site restrictions, landing is more casual and safe, and protects onboard equipment safety.
Field
1. Plan the route on site, take off automatically, and land.
2. Before performing the mission, add enough image control points and the field work is completed.
With the rapid development of mobile communication equipment, in the mobile communications network engineering design, according to the requirements of the network coverage, traffic distribution, anti-interference requirements and network service quality and so on the actual situation to select the base station antenna, the communication base station antenna is currently on the market work the characteristics of the narrow frequency band, such as directional literal outdoor antenna, The operating frequency band is 860~960Mhz. Those multi-band antennas have the characteristics of high manufacturing cost and complex structure. With the development of communication technology, especially the popularization of 3G communication technology, such antennas are difficult to meet the market requirements. Therefore, to avoid the above problems, it is necessary to provide a base station antenna that is simple to manufacture, low cost, and reliable in performance to overcome the alleged defects in prior art.
