A system to report the position and/or measured conditions of a railroad car using satellite communication. The system includes a rechargeable power supply and communications unit incorporating one or more solar cells in combination with a rechargeable battery and further including a bank of ultracapacitors. The equivalent series resistance or “ESR” of the capacitor bank is substantially less than the ESR of the battery thereby allowing peak power demands to be filled by rapid dissipation of stored charge from the capacitor bank without substantial involvement of the battery under normal conditions.

A tilt sensing apparatus, a system and a method detect the tilt of a vehicle using tilt sensing devices mounted to the vehicle. An accelerometer and a gyroscope provide orientation data to a processor. The processor calculates the tilt of the vehicle and provides an audible indication and/or a visual indication to an operator of the vehicle via a communications module. The communications module has a display panel accessible to the operator for receiving the tilt information. The system provides tilt information for different amounts of tilt of the vehicle. The method of detecting the tilt of the vehicle accumulates position data from the accelerometer and the gyroscope to provide tilt indications to the operator. The apparatus, system and method compare a tilt angle to preset values and generate corresponding output signals to the operator if the preset values are exceeded. The system disables a power take-off connected to the vehicle in the event of a tilt condition in which the vehicle may roll over.
