摘要： Devices and methods are directed to estimating a position of the device/user using a delta range measurement (DRM) module to measure a range difference between first and second range values for first and second time instants based on, e.g., carrier phase measurements. The time period between the first and second time instants may be greater than a periodic interval at which a new phase value is sampled. This architecture of the DRM module provides extended delta ranges values which also overlap in time, enabling a combination of improved dilution of precision and keeping fast generation of delta range values suitable for use in continuous filtering. A filter, e.g., a Kalman filter, may be used compute current estimates of two positions, or a combination of a position and a position difference, of the device based at least on the range difference and a priori estimate(s) of the position(s) of the device.

摘要： This disclosure relates to a control device for compensating misadjustment of a tunable code loop filter of a portable global navigation satellite system (GNSS) device due to movement of the GNSS device, the control device comprising: a waveform estimator configured to estimate a signal-to-noise ratio (SNR) waveform based on an SNR of a radio signal received by the GNSS device; and a controller configured to tune the code loop filter based on the estimated SNR waveform to compensate for misadjustment of the code loop filter due to movement of the GNSS device.
