Abstract
A device for determining a user positioning including an RF position locating device (e.g., a GPS receiver) for intermittently determining a reference position and an inertial sensing system for determining a position change from the reference position. A current position is determined from the reference position and the position change and the inertial sensing system operates at a lower power level than the RF position locating device.
