Performance testing Testing performed at the NIST campus at Gaithersburg, Maryland December 15, 2010 (temperature was ~33º F) 3 Different buildings Buildings #238, #222, #301 Various motion types Walking Forward, backward, sideways, up/down stairs Crawling 1 or 2 systems (GLU s) tested, separately and/or simultaneously Pre-surveyed truth points, spaced 3-4m apart Survey provided by DHS/NIST/CERDEC personnel Navigation data was recorded and provided to DHS for evaluation against truth points 10
Building 238 3 story wooden structure with vinyl siding Dimensions: 40 x 53 25 x 25 copper clad Faraday cage inside extending 2½ floors 5 x10 screen room on second floor 4 ANU s deployed Faraday Cage 11
Building 238 Results System worked as designed Ranging radio provided reliable and accurate position reference Dominated position performance Data communications worked well Offset between survey and GPS determined position resulted in bias Removing bias resulted in very good performance R95 performance < 1m 12
Building 222 3 floors, cinderblock construction Dimensions: 135 x 358 Floors: 6 poured concrete Interior walls are mostly wallboard, some cinderblock for major walls Track is primarily along hallways that are 1 office away from edge of building Heavy metal doors 4 ANU s deployed Entrance 13
Building 301 Large single floor office/warehouse building Dimensions: 456 x 491 Office areas vary from sheetrock to open areas to small offices with metal walls. Many test points in a warehouse section (supply room with metal shelves) Roof is sheet metal, a number of interior cinderblock walls Supply room area with metal shelves 4 ANU s deployed Entrance 14
Building 222, 301 Results Building material prevented reliable radio transmission Data communications was sporadic RF ranging was only present during exterior segments Navigation was primarily based on IMU/Doppler sensors Performance was sensitive to initialization errors Heading initialization caused tilt in position trace Position initialization difference caused offset Overall, relative navigation performed well 15
Conclusions RF communications and ranging performance is highly dependent on building type and configuration Difficult to assess RF characteristics from exterior observations Metalized window film Interior metal doors Reliance on relative navigator (non-rf) for extended ranging outages is crucial Data communications integrity is difficult and crucial 16
