PREDICTION OF FIELD STRENGTHS OF NSS AND NAA VLF TRANSMISSIONS

Abstract

The Naval Research Laboratory has been conducting an investigation of the VLF communications reliability in proposed Polaris launching areas. Long- term statistical propagation data have been recorded in the vicinity of the areas of interest along with short-term special experimental investigations. These data form the basis of this report which presents the necessary information for calculating the predicted field strengths of transmissions from NSS (22.3 Kc) and NAA (14.7 or 14.8 Kc) into the Norwegian Sea and surrounding areas. The field strengths can be calculated based on the time of day reception is desired, the reliability required, and, for submerged reception, the depth of the antenna in sea water.
