TECHNICAL PUBLICATION TRANSFORMING THE WAY THE WORLD WORKS GNSS/INS Performance The following results are from an analysis of a 13 km suburban environment drive with the system running in GNSS/INS(RTK), which starts near the base station and ranges out to about 9 km away from the base station. A significant improvement is seen in the 95% error ellipses of the horizontal positioning, shown for ProPoint in blue. This is the difference between the real-time GNSS/INS positions and a high-accuracy, post-processed truth trajectory using an Applanix POSLV system (high end IMU system). Similar improvements are seen in the vertical performance. Looking at the Cumulative Distribution Function plot of the error in the height component clear improvements are seen. With the previous generation GNSS/INS engine 95% of the heights (the 95 percentile) fell within 78mm of truth, now with the Trimble ProPoint Engine 95% of the heights fall within 23mm of truth. CONCLUSIONS Trimble's ProPoint Engine is an investment in the future, ready to fuse present and future GNSS measurements with Inertial and sensor data to deliver premium performance in the toughest of environments. When accuracy, availability and integrity are key requirements for your autonomous application then ProPoint is the ideal choice. TRIMBLE Email: Website: © 2021 Trimble Inc. All rights reserved.
