Abstract:
In a positioning system having an array of satellite navigation system antennas, each antenna having a receiver, the antennas simultaneously receiving signals emitted from a plurality of signal transmitters, a method for determining an attitude of the array comprising:determining a first set of potential solutions for a first baseline vector for any pair of antennas in the array, each of the potential solutions including an integer ambiguity value; determining a second set of potential solutions for a second baseline vector for any other pair of antennas in the array, each of the potential solutions including an integer ambiguity value; comparing each potential solution in the first set with each potential solution in the second set to determine a degree of geometric consistency between each pair of compared solutions; selecting one of the pairs of compared potential solutions as representative of the attitude of the array if the corresponding pair of baseline vectors satisfies predetermined criteria.
