How Accuracy Of Total Station Is Measured
The Accuracy Of Total Station is generally measured in terms of angular accuracy and distance accuracy.
Angular Accuracy
Angular accuracy refers to how precisely the Total Station measures horizontal and vertical angles. It is usually expressed in seconds such as:
- 1 second
- 2 seconds
- 5 seconds
- 10 seconds
Lower angular values indicate higher instrument precision.
Distance Accuracy
Distance accuracy refers to how accurately the instrument measures distances. It is commonly expressed in millimeters plus parts per million.
For example:
±(2 mm + 2 ppm)
This means the measurement may vary slightly depending on the measured distance.
Higher-quality instruments provide better distance accuracy and more reliable results.
