Abstract
Techniques for extended wide-lane carrier phase availability using inertial measurement unit (IMU) feedback are disclosed. The techniques can include determining an IMU-based position differential based on first IMU data received from an IMU of the mobile device, detecting a wide-lane cycle slip based on a wide-lane differential carrier phase (DCP) measurement and the IMU-based position differential, responsive to detecting the wide lane cycle slip, adjusting the wide-lane DCP measurement based on the IMU-based position differential to obtain a corrected wide-lane DCP measurement, and generating a global navigation satellite system (GNSS)-based positioning estimate for the mobile device based on the corrected wide-lane DCP measurement.
