Publication number: 20240118081Abstract: Calibrating an unstable sensor of a mobile device. Systems and methods for calibrating a sensor of a mobile device determine a first estimated position of the mobile device without using any measurement from the sensor of the mobile device, generate a second estimated position of the mobile device using a measurement from the sensor, estimate a sensor error of the sensor using the first estimated position and the second estimated position, and use the sensor error to determine a calibration value for adjusting one or more measurements from the sensor.Type: ApplicationFiled: December 14, 2023Publication date: April 11, 2024Applicant: NextNav, LLCInventors: Michael DORMODY, Ganesh PATTABIRAMAN, Abijith KUMAR, Thomas WOLF, Gary PARSONS, Christian GATES, Deepak JOSEPH, Badrinath NAGARAJAN

Patent number: 10598757Abstract: Estimating range bias in a timing-based radio positioning network. Systems and methods estimate range bias, and use the estimated bias to adjust an estimated range measurement for use in estimating a position of a receiver. Estimated range bias may be based on surveyed range errors associated with locations near the position of the receiver, or may alternatively be based on comparisons of different range measurements.Type: GrantFiled: April 6, 2017Date of Patent: March 24, 2020Assignee: NextNav, LLCInventors: Christian Gates, Arun Raghupathy

Patent number: 9933526Abstract: Systems and methods for estimating error associated with one or more range measurements that are used to estimate the position of a receiver. Estimations of range error may be based on surveyed range errors associated with locations near the position of the receiver. Estimations of range error may alternatively be based on comparisons of actual movement by the receiver to estimated movement between estimates of the receiver's positions.Type: GrantFiled: March 12, 2014Date of Patent: April 3, 2018Assignee: NextNav, LLCInventors: Christian Gates, Arun Raghupathy
