How to backsight on Topcon or Sokkia Total Station?

Back Sighting on a Topcon or Sokkia total station involves using a known point as a reference to establish a line of sight and orientation for your survey. Here's a general guide on how to backsight: 1. *Choose a Known Point:* - Select a point with known coordinates and elevation, preferably a benchmark or another surveyed point. 2. *Set Up the Total Station:* - Place the total station on a stable surface, such as a tripod. - Level the total station using the leveling screws or electronic leveling feature. 3. *Initialize the Total Station:* - Turn on the total station and follow the initialization procedure outlined in the user manual. 4. *Enter Known Point Coordinates:* - Input the coordinates of the chosen known point into the total station. This step is essential for accurate orientation. 5. *Sight the Known Point (Backsighting):* - Look through the total station's telescope and aim it at the chosen known point. This is the backsighting step. - Adjust the total station until the crosshairs align with the target point. 6. *Record Backsight Measurements:* - Record the horizontal angle, vertical angle, and slope distance to the known point. These measurements establish the reference direction for your survey. 7. *Set the Instrument to Zero:* - After recording backsight measurements, set the horizontal angle on the total station to zero. This simplifies subsequent measurements as they will be relative to the backsighted point. 8. *Survey or Measure Points:* - Proceed with your survey, measuring points relative to the backsighted direction. 9. *Check Backsight Periodically:* - Periodically check back to the known point to ensure that the instrument remains properly oriented. 10. *Verify Survey Accuracy:* - Once the survey is complete, verify the accuracy by comparing surveyed coordinates with known coordinates. Always refer to the specific procedures outlined in the user manual for your Topcon total station model, as steps may vary. Additionally, consider local surveying standards and practices for accurate and consistent results. #survey #viral #civilengineering #totalstationsurveytraining
