Abstract
Reception of omega or other VLF transmissions may be used to supplement Satellite Doppler navigation in two ways: To provide velocity data for improved doppler fix accuracy. To provide location data between satellite passes. These applications require VLF/Omega range-rate measurements based on time spans of the order of 15 minutes to several hours. Results of range-rate measurements relative to nine transmitters as received at Austin, Texas are presented here. Typical statistical results show two-thirds of the errors below ¼ knot during periods of all-daylight propagation and below ¾ knot during periods of all-nighttime propagation.Keywords
