Abstract:

Current air traffic operations over the North ATlantic NAT and the application of hybrid navigation systems to obtain more accurate performance on these NAT routes are reviewed. A digital computer simulation program NATNAV - North ATlantic NAVigation is developed to evaluate the performance of navigation systems for future commercial NAT aircraft operations. Error models are developed for aided-inertial navigation systems with external measurements from Doppler radar, Omega, satellite-ranging or air data. Modified author abstract
