Abstract

A positioning system that combines the use of real-time location system and a robotic total station into a single, transparent hybrid positioning system to locate one or multiple targets by one or multiple users.

releasing the RTS to a particular other one user of the plurality of users after the final position for target has been located using the rover associated with the particular one user.

6. The method of claim 4 further comprising:

transmitting a message to the RTS prior to the transitioning of the positioning from using the RTLS to using the RTS; and

locking onto, by the RTS, the prism as result of receiving the transmitted message.

7. The method of claim 6 wherein the message is transmitted from a mobile device associated with a user of the rover.

8. The method of claim 1 wherein the specified distance is twenty (20) centimeters.

9. The method of claim 1 wherein the first positioning system is a Global Navigation Satellite System (GNSS).

10. The method of claim 9 wherein the first positioning system uses both the GNSS and a real-time location system (RTLS) for the positioning of the at least one locating device.

11. The method of claim 7 wherein the monitoring of the rover is performed by a server in communication with the RTLS.

12. The method of claim 11 wherein the positioning of the rover using the RTS is operable for at least one position located within a structure resident on the site.

13. The method of claim 11 further comprising:

sending an alert message, from the server, to the mobile device upon determining that the distance is not greater than or equal to the specified distance.

14. The method of claim 7 wherein the mobile device is one of a smartphone, a wearable computer, and a tablet.

15. The method of claim 1 wherein each locating device of the plurality of devices is a rover having a tag and a prism.

16. The method of claim 7 wherein the message includes a search command and an angle for turning the RTS towards the rover.

17. A system for locating a target on site comprising:

a first positioning system configured for positioning at least one locating device of a plurality of location devices traversing the site;

a robotic total station (RTS) configured for positioning the at least one locating device of the plurality of location devices traversing the site;

a server;

a memory coupled with the server, the memory having a program that stores computer program instructions that when executed cause the server to perform operations for;

monitoring the at least one locating device;

determining if a current position of the at least one locating device is at a distance that is greater than or equal to a specified distance from the target;

if the distance is determined to be greater than or equal to the specified distance then causing the system to use the first positioning system for positioning the at least one locating device; and

when the distance is determined not to be greater than or equal to the specified distance then causing the system to use the RTS for the positioning of the at least one locating device until a final position for the target has been located on the site.

18. The system of claim 17 wherein the first positioning system is a real-time location system (RTLS).

19. The system of claim 18 wherein the at least one locating device is a rover.

20. The system of claim 19 wherein the rover includes a prism and a tag.

21. The system of claim 19 wherein the rover is associated with a particular one user of a plurality of users, each user of the plurality of users being associated with a particular one locating device, the operations further comprising:

releasing the RTS to a particular other one user of the plurality of users after the final position for the target has been located using the rover associated with the particular one user.

22. The system of claim 19 further comprising:

a mobile device configured for receiving a first message indicating that the distance is less than the specified distance, and, in response to the first message, transmitting a second message to the RTS instructing the RTS to lock onto the prism.

23. The system of claim 17 wherein the specified distance is twenty (20) centimeters.

24. The system of claim 19 wherein the first positioning system uses both the RTLS and a Global Navigation Satellite System (GNSS) for the positioning of the at least one locating device.

25. The system of claim 22 wherein mobile device is one of a smartphone, a wearable computer, and a tablet.

26. A robotic total station (RTS) comprising:

receiving a message indicating that control of positioning a locating device on a site by the RTS is desired, the message triggered by a determination that a current position of the locating device is at a distance that is less than a specified distance from a target on the site;

locking onto, in response to the message, the locating device;

transitioning the control of the positioning of the locating device to the RTS; and

positioning, by the RTS, the locating device until a final position for the target has been located on the site.

27. The robotic total station of claim 26 wherein the transitioning the control of the positioning of the locating device to the RTS is from one of a real-time location system (RTLS) and a Global Navigation Satellite System (GNSS).

28. The robotic total station of claim 27 wherein a transmission of the message is triggered by the RTLS.

29. The robotic total station of claim 26 wherein the locating device is a rover having a tag and a prism, and the specified distance is twenty (20) centimeters.
