Existing Job: Ground – TDS Localization
Scenario
You have already done a job at an existing site. The original job was
completed with a closed traverse starting from of an assumed
bearing, so there is no projection and no datum to define the local
coordinate system. You want to measure new points on this site with
your RTK GPS equipment, and calculate coordinates in the original
local system.
Objectives
This tutorial job will teach you:
¾ How to start a job from a control file.
¾ How to set the RTK base and rover.
¾ How to occupy control points and solve a localization adjustment in
Ground – TDS Localization mode.
¾ How to move the base station receiver to existing local points.
Procedure
1. Open a new job and import control points.
• Open a new job, tap Import a Control File and select
TDSControl_Ground.job.
2. Start the Survey from a new autonomous base.
• Go to Start GPS Survey, the first step will be the Choose
Projection Mode screen. Since you have a local ground level
coordinate system with no projection and no datum, tap Use
Ground – TDS Localization.
