The algorithm for the ambiguity resolution is the Best Integer Equivariant (BIE) algorithm. -The BIE algorithm generally reveals float ambiguities, not integers. However, the distance between the (float) BIE -result and the nearest integer (the fractional part of the BIE result) is a very good criterion for the -reliability of the resolved ambiguity. +The BIE algorithm is described in

+and generally reveals float ambiguities, not integers. However, the distance between the (float) BIE +result and the nearest integer (the fractional part of the BIE result) is a very good criterion for the reliability of the resolved ambiguity. In addition it is possible to compute a variance (or its squareroot – sigma) of each resulting BIE ambiguity.
