Sensor array measurements using select sensor pairs

A method of operating a positioning system having a sensor array, the method comprising:

• measuring a distance to a target object with the sensor array comprising at least three sensors, wherein the target object is in a coordinate system having a first coordinate axis and a second coordinate axis;
• identifying at least one first sensor pair aligned along an axis that corresponds with the first coordinate axis;
• processing measurements from the at least one first sensor pair to determine a first coordinate for the target object along the first coordinate axis;
• identifying at least one second sensor pair aligned along an axis that corresponds with the second coordinate axis;
• and
• processing measurements from the at least one second sensor pair to determine a second coordinate for the target object along the second coordinate axis.

A positioning system configured to determine coordinates for a target object in a coordinate system, the positioning system comprising:

• a sensor array comprising at least three sensors each configured to measure a distance to the target object;
• and
• a controller configured to identify at least one first sensor pair aligned along an axis that relates more with a first coordinate axis of the coordinate system than a second coordinate axis, and to process measurements from the at least one first sensor pair only to determine a first coordinate for the target object along the first coordinate axis;
• the controller configured to identify at least one second sensor pair aligned along an axis that relates more with the second coordinate axis than the first coordinate axis, and to process measurements from the at least one second sensor pair only to determine a second coordinate for the target object along the second coordinate axis.
