A navigation system can comprise a microprocessor, a memory, a navigational signal receiver configured to receive a radio signal from at least one external system, a motion sensing device, and a navigation program executable by the microprocessor. The navigational signal receiver can be communicatively coupled to the microprocessor via a communication port. The navigation program can be configured to receive messages from the navigational signal receiver by communicating to the driver of the communication port. The communication port driver can adjust the current position based on the data returned by the motion sensing device.
