1. A system for recording, processing, and transmitting data from a mobile asset, comprising:

  • a wireless processing unit having at least one axis;

    at least one digital video recorder onboard the mobile asset, the at least one digital video recorder adapted to perform recording or transmitting a still image file, a video file or an acoustic file in real-time;

    at least one inertial navigation sensor board onboard the mobile asset, the board comprising a microcontroller communicating with and processing data from a 3-axis accelerometer;

    at least one event data recorder onboard the mobile asset, the at least one event data recorder adapted to monitor real-time status of at least one input sensor and log event data relating to the mobile asset;

    firmware, running on the microcontroller, adapted to calculate pitch and roll based on an x-axis raw acceleration value, a y-axis raw acceleration value, or a z-axis raw acceleration value from the 3-axis accelerometer, to determine when at least one trigger event occurs, to send at least one trigger event message to the wireless processing unit when at least one trigger event occurs, or to send at least one periodic data message containing a predefined set of values to the wireless processing unit every second; and

    a software application running on the wireless processing unit, the software application adapted to;

    communicate with the inertial navigation sensor board;

    automatically calibrate a compass on the mobile asset;

    automatically orient the at least one axis of the wireless processing unit to at least one corresponding axis of the mobile asset;

    filter the x-axis raw acceleration value, y-axis raw acceleration value, and 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;

    translate the axes of the inertial navigation sensor board to the axes of the mobile asset and determine an x-axis translated raw acceleration value by translating the x-axis raw acceleration value to the axes of the mobile asset, determine a y-axis translated raw acceleration value by translating the y-axis raw acceleration value to the axes of the mobile asset, and determine a z-axis translated raw acceleration value by translating the z-axis raw acceleration value to the axes of the mobile asset;

    translate the axes of the inertial navigation sensor board to the axes of the mobile asset and determine an x-axis translated filtered acceleration value by translating the x-axis filtered acceleration value to the axes of the mobile asset, determine a y-axis translated filtered acceleration value by translating the y-axis filtered acceleration value to the axes of the mobile asset, and determine a z-axis translated filtered acceleration value by translating the z-axis filtered acceleration value to the axes of the mobile asset; and

    gather data from other software applications running on the wireless processing unit.
