July 1968: Irregular Terrain Model Published
In July 1968 one of ITS’s most famous publications was released. “Prediction of Tropospheric Radio Transmission Loss Over Irregular Terrain: A Computer Model” described a software product based on the groundbreaking work done for Tech Note 101 three years earlier. The FORTRAN program created by ITS engineers Anita Long...
