1. A sensor alignment system for establishing and maintaining accurate alignment of sensor target data, comprising: multiple sensors collocated on a common substrate and mounted on an automotive vehicle for gathering sensor target data around the vehicle using sensor information; a first micro-inertial sensor included with the sensors that measures at least one of rotation rate and acceleration along two or more axes of the sensors; a second micro-inertial sensor mounted on the vehicle that measures at least one of rotation rate and acceleration along two or more axes of the vehicle; and a processor configured to at least one of: use the first micro-inertial sensor to determine at least one of yaw, pitch and roll rate; use the second micro-inertial sensor to determine at least one of yaw, pitch and roll acceleration; determine speed from acceleration over time; determine distance from speed over time; determine a sensor reference frame; determine a vehicle reference frame; determine an amount of misalignment of the sensor reference frame with the vehicle reference frame; align the sensor target data with the vehicle reference frame according to the amount of misalignment.
