The application of two (or more) systems used to define position and taking into account the way they are related, makes it possible to improve both accuracy and reliability of the measured navigational parameters. The method of estimation with constraints is based on the method of determining extremes with constraints of many variables. In geodesy, this method is known as adjustment by conditions. %@ 2083-6473
