Claim Text:
1. A method for recording, processing and transmitting data from a mobile asset, comprising the steps of: a. at least one event data recorder, onboard the mobile asset, monitoring real-time status of at least one input sensor and logging data relating to the mobile asset; b. at least one digital video recorder, onboard the mobile asset, recording still images, video and acoustics in real-time; c. at least one inertial navigation sensor board onboard the mobile asset, said board comprising a microcontroller communicating with and processing data from a 3-axis accelerometer; d. reading an x-axis raw acceleration value, a y-axis raw acceleration value, and a z-axis raw acceleration value from the 3-axis accelerometer; e. filtering the x-axis raw acceleration value, y-axis raw acceleration value and the z-axis raw acceleration value into an x-axis filtered acceleration value, a y-axis filtered acceleration value, and a z-axis filtered acceleration value; f. translating the axes of the inertial navigation sensor board to the axes of the mobile asset and determining an x-axis translated raw acceleration value by translating the x-axis raw acceleration value to the axes of the mobile asset, determining a y-axis translated raw acceleration value by translating the y-axis raw acceleration value to the axes of the mobile asset, and determining a z-axis translated raw acceleration value by translating the z-axis raw acceleration value to the axes of the mobile asset; and g. translating the axes of the inertial navigation sensor board to the axes of the mobile asset and determining an x-axis translated filtered acceleration value by translating the x-axis filtered acceleration value to the axes of the mobile asset, determining a y-axis translated filtered acceleration value by translating the y-axis filtered acceleration value to the axes of the mobile asset, and determining a z-axis translated filtered acceleration value by translating the z-axis filtered acceleration value to the axes of the mobile asset.
