Applications
Anti-Jam
Jamming and interference, whether intentional or unintentional, can severely degrade GPS positioning, navigation, and timing availability, potentially leading to total signal loss. Ordinary GNSS devices may be disrupted and unable to operate normally in complex jamming and interference environments. Therefore, specialized anti jamming and anti interference devices are necessary to enhance the reception quality of desired signals and reject interference from unwanted signals to ensure receivers operate correctly.
Autonomous Vehicles
High-precision positioning is one of the core technologies to realize autonomous driving. It works as follows: GNSS signals are received from BDS, GPS, GLONASS and GALILEO through high-precision positioning antenna; and simultaneously, RTK differential data is received from ground based augmentation system through 4G and 5G antennas. In the SOC of GNSS positioning antenna, various errors on the data chain are eliminated through RTK algorithm, then centimeter-level and even millimeter-level positioning accuracy can be achieved. The whole process provides stable and reliable absolute positioning information for the high-precision fusion positioning system.
Precision Agriculture
Agricultural machinery unmanned driving system is a comprehensive system integrating satellite signal reception, positioning & orientation and automatic control. GNSS high-precision satellite navigation system is the key to automatic driving system, mainly composed of GNSS high-precision antennas and positioning & orientation terminals. It can obtain high-precision position information in real time. According to the parameters such as the position and attitude, automatic driving system sends instructions to the steering system in real time based on the calculation of the controller. In this way, agricultural machinery can work according to the planned route of the navigation displayer.
Robotics
GNSS technology enables high-precision, high-speed real-time navigation and positioning, making it a primary technology for outdoor autonomous positioning. Through differential positioning and precise point positioning techniques, outdoor robots can achieve real-time positioning accuracy at sub-meter, decimeter, and centimeter levels; or they can be combined with inertial navigation, vision, and radar sensors for high-precision positioning in various complex scenarios.
Survey
The reference station obtains accurate location information through long-term observation and transmits the observation data to the control center in real time through the data communication system. The control center calculates the error correction parameters in the area and then sends the error information to the rover (user terminal) through ground-based augmentation system, wide-area augmentation system, satellite-based augmentation system, etc. Through RTK real-time dynamic measurement technology, the user finally obtains accurate coordinate information, empowering measurement and mapping applications.
UAV
Relying on high-precision positioning technology, it receives full-band signals from four major systems: GPS, BDS, GLONASS, and GALILEO, providing strong satellite signal support for the drone from multiple systems and directions. In addition, it can effectively handle inter-system interference in multi-communication frequency band operating environments, ensuring the drone's flight stability and high safety during automatic cruise.
