NEURAL NETWORK AIDED KALMAN FILTERING FOR INTEGRATED GPS/INS GEO-REFERENCING PLATFORM

by Jianguo Jack Wang A, Jinling Wang A, David Sinclair B, Leo Watts B
"... Kalman filtering theory plays an important role in integrated GPS/INS georeference system design. A Kalman filter (KF) uses measurement updates to correct system states error and to limit the errors in navigation solutions. However, only when the system dynamic and measurement models are correctly d ..."
