RTK product of TopXGun is especially designed for high-precision flight of the UAVs. It has several product mixes to allow the customers to make selections according to their own demands.
DGPS RECEIVER Air–Standard is especially designed for the high-precision flight of the UAVs. It is compatible with T1、T1-A and T1-Pro to make the UAVs achieve the cm-level precise position. The internal board of DGPS RECEIVER Air–Standard adopts GPS+GLOANASS+BDS trial-system-five-frequency high dynamic calculating engine which supports the super long baseline E-RTK measurement. The frequencies received by the board include GPS L1/L2, GLOANASS L1/L2 and BDS B1. It supports GPS/GLONASS/BDS single system independent position and GPS+GLONASS+BDS joint system position, adapted to more severe and longer-distance position environment.
cooperate with RTK differential base station to provide the cm-level position precision but also orientate the air craft precisely through double antennae. Compared with the traditional orientation by magnetic compass, the double-antenna orientation way can eliminate the influence of magnetic interference and ensure the flight safety of the aircraft under the high voltage wire and in the mining area with strong magnetic interference. DGPS RECEIVER AIR – Ultimate supports all existing satellite navigation systems. The received frequencies include GPS L1, L2, L2C, GLONASS L1, L2, BDS B1, B2, and GALILEO E1, E5. It can use the dual-frequency signals of GPS, GLONASS and BDS at the same time for positioning as well as RTK calculating. With higher positioning accuracy, it is more widely applied.
The differential system of the mobile base station consists of one-piece mobile base station, data link and differential module. In actual work, the position data of the ground base station is broadcast in real time through data link. The differential module integrates the data from satellite and the position information received by the on board data link terminal for RTK calculation, so as to realize the cm-level high-precision positioning.
The differential system adopts data link of 10,000 power to make the transmission distance longer. When flying close to the ground (<100m) the transmission distance can be 2000 to 3000m; when flying in the high sky (>300m), the transmission distance can reach over 10000m. In addition, the data link also has high anti-interference ability, so it is very stable and reliable with low BER.
The ground-terminal data link can support several on board data links to transfer and receive flight data at the same time. Several aircraft can use the same base station for RTK differential positioning at the same time, so as to achieve the cm-level precise flight.
The ground-terminal differential system is portable to meet the operation requirements of the users in different regions.
The network base station differential system comprises a communication module TDTU and a differential module。TDTU embedded search service account，Anytime and anywhere, the location data of the CORS system can be received by the location system of the Unicom through the Internet of things。The differential module calculates the data transmitted by the location of the position and the data of the observation position itself，Achieve centimeter level precise positioning.
Chihiro CORS system RTK based on differential positioning principle, relying on the foundation to enhance the satellite positioning throughout the station, the integration of various types of positioning technology, the Internet provides high availability 7*24 hour differential broadcast service, all kinds of terminal and application system for 23 provinces and cities nationwide scope, provides the position correction data service cm level accuracy.Through a position finding CORS system, the aircraft can achieve precise flight throughout the country.
When using the network version of RTK products to connect with the public CORS system, the user does not need to set up a base station, so it only needs to carry drones, so that the flight can be relieved from heavy equipment and is more convenient to use.
