Abstract
In some implementations, a global navigation satellite system (GNSS) device may determine a plurality of position estimates of the GNSS device for a plurality of epochs spanning a period of time beginning with a first epoch and ending with a second epoch. The GNSS device may determine position change values comprising a position change value of the GNSS device for each successive epoch of the plurality of epochs based at least in part on delta carrier phase (DCP) values for the plurality of epochs. The GNSS device may perform backward smoothing on the plurality of position estimates, modifying at least a portion of the plurality of position estimates based at least in part on the position estimate of the second epoch and the position change values. The GNSS device may output information indicative of at least a portion of the modified position estimates of the GNSS device.
