"This is a great technological achievement: we are using the tiny Doppler shift in the radar echo to infer fall speeds of only around one metre-per-second, and this is from a satellite that is ...

2010, Hammerschlag et al. 2011). Satellite-linked transmitters (SAT) tags SAT tags accurately determine geographical locations via Doppler-shift calculations and transmission to orbiting ARGOS ...

Following this observation, Dr. Frank T. McClure (of APL) realized that if the satellite orbit was known, a user's location could be determined based on the Doppler shift measurements. Using this ...

Redshift is also the name of the factor z indicating the relative change in wavelength due to the Doppler shift for a receding galaxy. The Doppler equation used for sound calculations cannot be ...
