Auxiliary power unit power compensation using global positioning system for altitude

A method for controlling an operation of a transport power system, the method comprising:

• determining, by a controller of the transport power system, an altitude of the transport power system with respect to sea level based on global positioning system (GPS) data received by a GPS receiver, a diesel prime mover being separate from and independent to a vehicle engine used for operating a vehicle, the prime mover not being configured to move the vehicle, the controller being configured to communicate with the prime mover and the GPS receiver;
• determining a power output of the prime mover;
• adjusting, by the controller, a power output upper limit for the prime mover based on the determined altitude;
• comparing the power output of the prime mover and the adjusted power output upper limit;
• and
• operating, by the controller, the prime mover of the transport power system so as not to exceed the adjusted power output upper limit.
