High Resolution HF Time of Arrival Measurements (1981-1985),
Abstract
Between 1981 and 1985, absolute time of arrival (TOA) measurements were made on HF skywave time standard signals at different frequencies. 113 path-months of TOA data were collected over a one hop path between Ft. Collins, CO, and San Diego, CA. In addition, 15 path-months of data were collected between Ft. Collins and Oahu, HI, and 12 path-months were gathered on signals between Tokyo, Japan and Oahu. The data show a higher degree of ionospheric movement than was expected. It also shows a higher degree of stratification within layers than can normally be explained with simple, single layer ionospheric assumption.
