Using Locata and INS for Indoor Positioning
نویسندگان
چکیده
In this paper, the authors describe the integration of an INS and the Locata system, that uses Locata’s position, velocity and attitude solutions to calibrate INS observations in order to achieve an accurate, robust and continuous indoor navigation solution. The multi-sensor experiment conducted at Locata’s Numerella Test Facility is described in the paper. The measurement data were collected and post-processed to evaluate the overall positioning performance and to analyse limitations of the integrated system. The test results indicate that Locata can be a substitute for GNSS, providing positioning services in severe multipath indoor environments, and the integrated system is capable of high accuracy, seamless navigation. Keywords-Indoor positioning, Locata, INS, Multi-sensor integrated system

The Global Positioning System (GPS) can provide centimetre-level positioning accuracy in “open-sky” environments. However, GPS coordinates become unavailable in difficult urban, suburban and rural environments because the GPS signals may be partly or completely blocked by trees and buildings. Applications such as underground asset mapping or locating unexploded ordnances require a “seamless” pr...
