Abstract
The aim of the invention is to limit the number of possible phase ambiguity resolutions when taking measurements by means of satellite-aided positioning systems. Said aim is achieved by a method which allows the search sector to be better restricted. To this avail, information about the geometry of an antenna array is used for establishing restrictions for said antenna array. Said restrictions allow the search sector and thus the number of acceptable resolutions to be successively reduced. A restriction comprises the utilization of the connecting line between two antennas (A, A) that define a primary base line (S). An additional, secondary base line (S) can be calculated by inventively parameterizing the degree of rotational freedom of said secondary base line (S) about the primary base line (S) such that the process is accelerated.
