Title: Safeguards Technology Development Program 4th Quarter FY 2018 Report September 30, 2018

Abstract

This is an evaluation of candidate navigation solutions for GPS free inspection tools that can be used in tours of large building interiors. In principle, COTS portable inertial motion unit (IMU) sensors with satisfactory accuracy, SWAP (size, weight, power), low error, and bias drift can provide sufficiently accurate dead reckoning navigation in a large building in the absence of GPS. To explore this assumption, the capabilities of representative IMU navigation sensors to meet these requirements will be evaluated and field tested, starting with a market survey. To test the candidate COTS IMUs drawn from the market survey, we will design and fabricate a person-portable backpack for testing. We will provide a mobile power supply and data collection port. Then, we will test the IMUs on interior building tours at LLNL, finally carrying out an analysis of these sensors’ performance using LLNL’s navigation codes.
