VLF/LF Propagation Measurements Over Long Paths On Board a High-Speed Aircraft

Abstract

Field strength measurements in the Very-Low-Frequency and Low- Frequency (VLF/LF) range are being conducted around the Western Hemisphere on board RADC's KC 135 aircraft. Data from these flights will provide a basis on which present propagation prediction models can be compared. Adjustment of present prediction models to real-world data will provide the Armed Services with reliable and accurate means of predicting message reception success and, hence, allow Command and Control to make the necessary communications adjustments for insuring the most reliable message transmission. This report describes the flights and data collected on paths from Griffiss AFB NY to Mildenhall, England, and return; Griffiss AFB to March AFB CA then to Eielson AFB, Alaska, and return to Griffiss AFB; and a round-robin flight from Griffiss AFB to the area around and over Silver Creek, Nebraska, and return. The frequencies monitored were: 34.5 kHz Silver Creek; 36 kHz Forestport, NY; 37.2 kHz Hawes, CA; 60 kHz WWVB, Boulder, Colorado; and 19.6 kHz - GBZ - Criggion, England.
