NavTK/TGRS Modeling: - AGI

Current WorkNon-TerminatedTrajectoryError “Adjusted”Terminated TrajectoriesNotional• Adjust 1 sigma error computations in NavTK to 3sigma values (using empirically derived multipliersappropriate for GPS*)• Compute max/min ENU error positions combinedwith max/min velocity errors to get “adjustedlaunch points”NotionalError “Adjusted” IIPs• Fly “adjusted launch point” trajectories to impactusing two-body propagator• Measure against EWR-127 standards to get Go/No-Go times• Repeat for each second of flight and for eachminute of the launch window* This work, by Ted Driver, AGI, is in progress.AGIPg 9 of 10NotionalNominal IIP at aSpecified TerminationTimewww.agi.com
