Standard Precision GNSS Products Features
UFRIN technology uses original output of the already-existing inertial sensor to determine whether the vehicle's motion and navigation's filtered error converge without considering the installation angle. Once the GNSS has been lost, the algorithm estimates the car movement's restrictions and creates virtual observation to suppress the accumulation of IMU's error. This will help to ensure unrestricted installation and MEMS accuracy and keep the navigation stable, reliable and accurate. It includes data collection, vehicle's movement verification, carriage phase convergence verification, installation angle / installation angle error calibration and vehicle's integrated position. This kind of technology will help to reduce the dependency on the satellite information and improve navigation's reliability in the complex landscape of modern urban areas.
FAQS
Standard Precision GNSS Products FAQs
What is the inertial navigation deviation of UM220-IV INS module for half an hour?
There will be 10 to 15 meters deviation for the inertial navigation with odometer input after running for 3 kilometers. The actual accuracy of inertial navigation may vary due to the difference in application environment and the deviation indicators.
The deviation of pure inertial navigation of Unicore products is 5% of the driving distance (without odometer, about 5 meters deviation for 100 meters distance). With the odometer input, the accuracy will be improved and maintains precise for a longer time.
What is the difference between the positioning accuracy unit RMS and CEP?
There are three units of the positioning accuracy: CEP, RMS, and 2DRMS. RMS is 1 sigma or 1 standard deviation; if the result is unbiased, the probability is 67%. 2DRMS is 2 sigma or 2 standard deviation, and the probability is 95%. The conversion rules between the three units are as follows:
CEP × 1.2 = RMS
CEP × 2.4 = 2DRMS
