Project Background
An intelligent driving test base needs to conduct autonomous driving algorithm testing in an indoor laboratory and semi-enclosed garage. The original signal solution cannot provide a stable RTK fixed solution, has large positioning drift, and exceeds the time delay, making it unable to meet the test standards.
Cooperation Content
1、 Product application: Deploy 6 sets of dish-shaped four-star full-frequency active outdoor antennas, 6 RTK dedicated signal forwarding hosts, and 24 sets of full-frequency passive indoor antennas to achieve full-area RTK high-precision signal coverage.
2、 Implementation highlights: outdoor high-gain capture, indoor coverage without blind spots； Full-frequency compatibility, low-latency forwarding, no changes to the protocol of the device under test, ready to install and use.
Project Results
1、 Product level: RTK fixed solution retention rate is 100%, positioning accuracy is ±1cm in plane and ±2cm in altitude, system forwarding delay is <10ms, and lock-out and re-acquisition time is <1 second.
2、 Customer value: Seamless switching between indoor and outdoor positioning, test interruption rate reduced from 23% to 0, test efficiency increased by 65%, data qualification rate 100%, meeting all-weather testing requirements for autonomous driving.
Customer Feedback
“The RTK high-precision signal coverage system operates stably and maintains centimeter-level accuracy throughout the entire process, solving the problem of being unable to conduct autonomous driving tests indoors. The data is reliable and efficiency is greatly improved. ”
