The safing system employs a multi-axis accelerometer system and multi-axis gyroscope system and a processor that is programmed to iteratively read acceleration data from the accelerometer system and apply a multi-axis rotation on the acceleration data using gyroscope data iteratively read from the gyroscope system to generate rotationally corrected acceleration data and further programmed to calculate a cumulative distance measure using the rotationally corrected acceleration data. The processor then compares the cumulative distance measure with a predetermined reference measure and to issue a control signal to enable arming of the device when the cumulative distance measure exceeds the reference measure.

Disclosed is a data recorder for munitions. The data recorder includes a power source, a processor, and an acceleration sensor. The data recorder further includes a trigger validation feature which is operably coupled to the data recorder to verify the occurrence of a secondary environmental/input event. This envisioned data recorder can contain a digital or analog device as a primary or secondary trigger. Data from an accelerometer is stored in FRAM memory.
