Product overview
SNC100C-DGI integrated navigation system is composed of MEMS sensors and high-end GNSS receiver board (novatel-718d), which is realized by multi-sensor fusion and navigation algorithm. The product has high reliability and strong environmental adaptability. By matching different software, the products can be widely used in UAV, unmanned vehicle, surveying and mapping, marine compass, stable platform, underwater vehicle and other fields.
1. Main functions
The integrated navigation system can use the satellite navigation information received by the GNSS receiver for integrated navigation, and output the pitch, roll, heading, position, speed, time and other information of the carrier; After losing the signal, output the position, speed and attitude information of inertial solution, and have a certain navigation accuracy maintenance function in a short time. During integrated navigation, the original information that can be used for post-processing can be output for processing by IE post-processing software of novatel.
