Abstract
A method of variable rate measurements in a device. The method generally includes the steps of (A) generating an intermediate signal conveying both a position of the device and a velocity of the device in response to a plurality of navigation signals received from external the device, (B) calculating an extrapolated position of the device at a second time based on the position and the velocity both measured at a first time, (C) adjusting an interval between the second time and a third time in response to a difference between the extrapolated position and the position measured at the second time and (D) generating a position signal conveying the position and the velocity, wherein the third time occurs after the second time and the second time occurs after the first time.
