Core Pain Points
1. Satellite signals in closed environments such as indoors, garages, and tunnels are severely attenuated and cannot meet the needs of RTK centimeter-level positioning.
2. Ordinary antennas have insufficient signal gain and weak multipath suppression capabilities, resulting in positioning drift, loss of lock, and inability to stably output fixed solutions.
3. Multi-system and multi-frequency signals are incompatible, and differential data synchronization is poor, affecting positioning accuracy and operation continuity.
4. Signal availability is low in complex occlusion environments, and drones, robots, and autonomous driving tests cannot operate continuously.
Core of Customized Solutions
Technical Adaptation
It adopts four-star full-frequency signal pure reception technology, RTK high-precision low-latency forwarding technology, multi-path suppression and anti-interference technology, and indoor uniform coverage technology to support stable operation of satellite signals.
Product Portfolio
1. Dish-shaped four-star full-range active outdoor antenna: responsible for high-sensitivity signal capture.
2. RTK dedicated signal forwarding host: amplifies and filters satellite signals received by outdoor antennas to improve signal strength in complex environments. Excellent out-of-band suppression can effectively resist interference from other useless signals.
3. Full-frequency passive indoor coverage antenna: responsible for uniform indoor signal coverage.
Implementation Process
1. On-site survey of the operating area and shielding environment, and customized antenna points and forwarding plans.
2. Rapid deployment and debugging, all-weather technical support.
Core Advantages of the Solution
1. The dish-shaped active outdoor antenna has a gain of 40dB, four-star full-frequency compatibility, strong multipath suppression capability, and a fixed solution retention rate of ≥99.9%.
2. The full-frequency passive indoor antenna covers evenly, and the indoor positioning accuracy stably maintains ±1cm in plane and ±2cm in elevation.
3. The system forwarding delay is less than 10ms, and the lock-out and re-acquisition time is less than 1 second, which meets the requirements of highly dynamic operations such as autonomous driving, robots, and surveying and mapping.
Application Scope
Autonomous driving closed test field, drone laboratory, AGV/robot workshop, surveying and measurement room, tunnel/garage, scientific research institute, high-precision positioning production line testing.
