Abstract
Representative data are presented for the original Block 3 and Block 4 zero delay devices as a function of antenna elevation angle. Instabilities on the order of 33 nanoseconds as obtained with the original S-band Block 3 system are reduced by relocation of the zero delay device (ZDD) horn. However, unsatisfactory performance at X-band for the Mariner Venus/Mercury 1973 (MVM’73) S/X experiment ZDD requires a reconfiguration eliminating the horns and associated air path.
