1. A method of calculating a position of a Global Navigation Satellite Systems (GNSS) device, the method comprising:
receiving a first set of GNSS data corresponding to a first epoch, for the first epoch, calculating a corresponding filter state;
receiving a second set of GNSS data corresponding to a second epoch that is after the first epoch;
after receiving the second set of GNSS data, calculating a position of the GNSS device based on the retrieved first set of GNSS data and the second set of GNSS data; and
using information from the second set of GNSS data, updating the calculated filter state for the first epoch.
