In today’ s world as smart munitions become increasingly complex, it became mandatory to monitor the activity of munitions during launch and flight by means of gathering critical operational data. This critical data is also very important to reduce the development cost, development time and failure investigation effort. The most challenging part of this study is that the instrument developed for monitoring munitions’ activity must withstand very harsh environments that munitions experience.
Since existing data acquisition systems are too big to fit inside newly developed munitions, a miniature and shock hardened on board data acquisition unit is developed. The unit acquires several analog and digital channels and has an SPI interface for on board recording or real time transmitting. This unit is successfully operated and flight data is collected.
In this paper, the properties of the data acquisition unit such as size, analog and digital channels, data storage capacity and data recording and transmitting algorithm are explained and test results are presented.
