Recent developments in airborne Doppler and ground mapping navigation radars and ground and satellite based radio systems are described. Simultaneous lobing and slope tracking techniques can remove the well-known Doppler sea bias error. Doppler velocity information can be extracted from coherent forward-locking mapping radars, and high position fixing accuracy can be achieved by synthetic aperture radars. In radio navigation systems, direct-ranging and differential techniques greatly reduce the geometric dilution and propagation effects.
