   - The Lever Arms are from the GPS/IMU to the GPS antenna in reference to the vehicle body frame. This reference frame is Y– Forward, X– to the Right, and Z– Up. By being inline with this reference frame the  measurements will be positive values and negative values in the opposite directions. So if we were measuring from the IMU to the GPS antenna and Y was Backward and Z was Down and X was Left then our values would be negative.   - The Lever Arms are from the GPS/IMU to the GPS antenna in reference to the vehicle body frame.
