Abstract
A state of a device is tracked based on transmissions from a global navigation satellite system (GNSS) by executing multiple probabilistic estimators concurrently tracking the state of the device using at least two measurement models of different size connecting the GNSS measurement data with the state of the device. One estimator tracks the state of the device based on a first measurement model using the code measurements. Another estimator tracks the state of the device based on a second measurement model using the GNSS measurement data masked by a binary mask blocking a subset of GNSS measurement data of a subset of the satellite signals based on values of coefficients of the binary mask. The number of measurements in the first measurement model is smaller than the number of measurements in the second measurement model.
