Interagency Field Experimentation JIFX event hosted by the Naval Postgraduate S chool Most measurement were taken at an altitude of 100 feet AGL with a handful of measurements made near the signal source at an altitude of 50 feet AGL When the localization algorithm was tested a 9 by 9 grid each cell 11 meters on a side was used as the world with the signal source located in the top right cell and the vehicle starting in the center cell 62 meters from the signal source RESULTS During flight tests with the JAGER vehicle 88 different experimental gain patterns were created and bearing calculations were made with each of the three previously described methods FIGURE 4 Location of all experimental gain pattern measurements colored by signal strength from 65dBm green to 80dBm red The POMDP based localization algorithm was successfully executed to locate the signal source Leveraging the performance results of the crosscorrelation and max3 methods the model for the POMDP was updated and produced a significantly different flight profile In addition to the POMDP based localization algorithm a baseline algorithm was also used to demonstrate the advantages of the POMDP based algorithm Effects of Distance Throughout the experiment measurements were made at distances from the signal ENC 2016 EUROPEAN NAVIGATION CONFERENCE 2016 30 MAY 02 JUNE 2016 HELSINKI FINLAND CALL FOR PAPERS CALL FOR SPONSORS AND EXHIBITORS NOW OPEN Innovative Technical Program Please Visit www enc2016 eu FEBRUARY 2016 WWW GPSWORLD COM GPS WORLD 51 IMPORTANT DEADLINES Full paper Submission Full Paper Peer Review 15th February 2016 Abstract Submission Light Peer Review 15th February 2016 Acceptance Notification 31th March 2016 Early Registration 15th April 2016
