Abstract : A series of week-long experiments on a downlink were conducted by the MILSATCOM groups at CRC and DREO. The software developed for these experiments included a reliable and robust data logging package to record the setup and measurement data required for post experiment analysis. The software provided the Skynet EHF Trials with a data logging package written in "C" that would interface with the existing serial communication software. The package was used as a real time storing device for recording experimental data such as hop power, noise power spectral density and pointing angles. In addition to data logging, the software had to provide several date and time references using the zulu time provided by a GOES satellite clock as the Trials' time reference. The software was loaded in a computer called Data Logger and was responsible for opening and closing all high and low level communications with the processors linked to it.
