Surveying methods and apparatus
First Claim
1. A surveying system, comprising:
- a. at least one target havingi. a unique address for wireless communication,ii. a wireless communication unit operable to activate a selected total station to identify and measure location of a chosen target, andiii. an identification unit comprising a modulated light source for transmitting modulated light employing a modulation scheme for the modulated light which is unique to the chosen target to enable identification of the chosen target by the selected total station, wherein the modulation scheme is adapted to be modified prior to operating the wireless communication unit to activate the selected total station to search for the chosen target, identify the chosen target and measure location of the chosen target, andb. at least one total station activated by wireless communication to search for the chosen target, identify the chosen target and measure location of the chosen target.

Abstract
The invention relates to a surveying system, comprising at least one total station unit (210, 220), and at least one target (201, 203), said targets having wireless communication means, each unit provided with a unique wireless communication address for wireless communication, the wireless communication to be used to activate a selected total station (210, 220) to identify and measure the location of a chosen target (201, 203) in relation to a relative reference system, each target having identification means to be used by the total station for identification of the chosen target, each total station having identifying means used for identification of the chosen target to be measured. The invention also relates to a target and a method for surveying using the total stations and the targets according to the system.

12. A method of surveying with at least one total station positioned and aligned in a coordinate system, comprising:
-
a. Placing a target at a location to be measured, the target having;
a unique address for wireless communication, a wireless communication unit operable to activate a selected total station to search for the target, identify the target and measure location of the target, and an identification unit comprising a modulated light source enabling identification of the chosen target by the selected total station,b. Transmitting modulated light from the identification unit employing a modulation scheme for the modulated light which is unique to the target to enable identification of the target by the selected total station, c. Modifying the modulation scheme prior to operating the wireless communication unit to activate a selected total station to search for the target, identify the target and measure location of the target, and d. Operating the wireless communication unit to activate a selected total station to search for the target, identify the target and measure location of the target. - View Dependent Claims (13, 14, 15)
