This report discusses the implementation of a quality control system for the Digisonde Drift Analysis. The quality checking of the integrity of the drift data being recorded is available for the online ODDA as well as the post processing DDA packages. This system indicates the performance of the Digisondes in the field by interrogating the drift measurements made. Loss of receiver performance, phase data, and received signal is quickly identified by the quality control system. This system allows the operator to identify problems in the field within an hour of occuring. while for post processing of data, the package indicates how well the Digisonde system was performing even in those rare cases of data collected over a few years where logs of station maintenance no longer exist.
