A system for real-time determination of calibration of an inertial measurement unit includes an inertial measurement unit and a processor in electronic communication with the inertial measurement unit. A road mapping module receives a vehicle latitude and a vehicle longitude, and determines a virtual heading angle of a vehicle. A virtual acceleration module receives the virtual heading angle of the vehicle, and a measured vehicle speed and heading angle, and estimates a virtual lateral acceleration and a virtual longitudinal acceleration. A correlation module receives the virtual lateral acceleration, the virtual longitudinal acceleration, a calibrated measured lateral acceleration, and a calibrated measured longitudinal acceleration. The correlation module determines a correlation between the virtual lateral acceleration and the calibrated measured lateral acceleration, and between the virtual longitudinal acceleration and the calibrated measured longitudinal acceleration. A notice is generated by the correlation module indicating a result of the correlation.
