Treating them as interchangeable sensors creates bad measurements quickly.</p> <p>A GPS receiver estimates geographic position from satellite signals. Two position fixes can be converted into an approximate distance across Earth&rsquo;s surface. An IMU such as the MPU-6050 measures acceleration and angular rate along its axes. Those measurements can be used to estimate tilt, rotation, and short-term motion.</p>
