Abstract
A method of enhancing the accuracy of a navigation system which includes a GNSS receiver. The method includes receiving navigation signals from at least one GNSS constellation and a LEO constellation. Position estimates will be made through implementation of a filter using successive readings of pseudoranges and carrier-phase measurements from the GNSS constellation and carrier-phase measurements from the LEO constellation.
