How to Use: The utility model relates to the technical field of unmanned aerial vehicles, in particular to an RTK antenna installation structure and an unmanned aerial vehicle. The RTK antenna is installed on the unmanned aerial vehicle body and connected with a signal line, and the installation structure includes a support frame, a fixing piece and a connecting piece, the RTK antenna is fixed to the upper part of the support frame, the bottom of the support frame is fixed to the upper part of the body and is connected to the fixing part at the bottom of the body through the connecting part, and the signal wire passes through the support off the shelf. The RTK antenna installation structure provided by the utility model solves the shortcomings of the inconvenient installation of the existing RTK antenna. The structure is simple and reasonable, and the installation and disassembly are relatively convenient. An opening for the signal line to pass through can be opened on the circular connecting pipe according to the needs. The selective installation of the RTK antenna in an appropriate position overcomes the limitation of the existing installation structure of the installation position, which is beneficial to ensure the positioning accuracy.
Features:
1Multi-arm spiral technology is used to ensure right-hand circular polarization and phase center performance, and reduce the influence of measurement errors 2The antenna unit adopts air medium, which has the characteristics of high gain and small gain roll-off 3Possess a good receiving effect for low-elevation satellite signals, ensuring that the satellites can still be received normally in some occasion with tighter obscuration 4The three-proof outer cover provides a guarantee for the antenna to work in the field for a long time 5Suitable for occasion that require volume and weight. Such as drones, small RTKs, sub-meter flat-panel hand-held devices, etc. 6Supporting the L1 and L2 dualband satellite navigation signal reception of for Beidou II/GPS/GLONASS/GALILEO systems, and meets the current multisystem compatibility and the demand for highaccuracy measurement, can be widely used in highaccuracy navigation and positioning occasion such as portable equipment and drones
