Total station with gnss device

A method comprising:

• at a surveying system comprising a total station, a GNSS device, and a coupling mechanism for coupling the GNSS device with the total station:
• positioning the total station and the GNSS device at a first point;
• determining, based on one or more outputs from the GNSS device, whether a set of GNSS signals is available;
• in accordance with a determination that the set of GNSS signals is available, determining, based on one or more outputs from the GNSS device, a first position of the first point;
• repositioning the GNSS device a distance away from the total station at a second point;
• determining based on one or more updated outputs from the GNSS device a second position of the second point;
• and
• calibrating one or more encoders of the of the total station based at least in part on the first point and the second point.

A surveying system, comprising:

• a total station, comprising:
• a camera,
• a laser module,
• one or more motors configured to reposition the camera of the total station, and one or more encoders configured to measure vertical and horizontal angles from
• the total station to a target;
• a GNSS device, comprising:
• a GNSS antenna for receiving position data from a plurality of satellites;
• a coupling mechanism for coupling the GNSS device with the total station;
• wherein the surveying system is configured to:
• determine, based on one or more outputs from the GNSS device, whether a set of GNSS signals is available;
• in accordance with a determination that the set of GNSS signals is available, determining, based on one or more outputs from the GNSS device, a first position of a first point;
• repositioning the GNSS device a distance away from the total station at a second point;
• determining based on one or more updated outputs from the GNSS device a second position of the second point;
• and
• calibrating one or more encoders of the of the total station based at least in part on the first point and the second point.

A non-transitory computer-readable storage medium storing one or more programs, the one or more programs comprising instructions, which when executed by one or more processors of a surveying system comprising a total station, a GNSS device, and a coupling mechanism for coupling the GNSS device with the total station, cause the surveying system to:

• determine, based on one or more outputs from the GNSS device, whether a set of GNSS signals is available;
• in accordance with a determination that the set of GNSS signals is available, determining, based on one or more outputs from the GNSS device, a first position of a first point;
• repositioning the GNSS device a distance away from the total station at a second point;
• determining based on one or more updated outputs from the GNSS device a second position of the second point, and
• calibrating one or more encoders of the of the total station based at least in part on the first point and the second point.
