Abstract
A target of a geodetic system based on global and local identification references. The target comprises a light emitter (LE) for emitting n predetermined modulated light patterns (MLPs) permanently assigned to one of m (m>n) global identification reference (GIR). The target transmits or receives data based on the assigned GIR. The geodetic system further comprises a geodetic surveying instrument comprising an optical sensor (OS) receives the MLPs and digitizes them using a fast sampling analogue-to-digital converter (ADC). A computing system selects one of the targets or receives a selection of the at least one target assigned to a selected GIR. One of n local identification references (LIRs) is temporarily assigned to the selected GIR. The light emitter of the selected target is directed to emit an MLP corresponding with the assigned LIR. Thus, by detection of the assigned LIR, the selected target is identified.
