    Measure Horizontal Angles by Repetition Method

    Uploaded by

    There are two methods for measuring horizontal angles: the repetition method which uses a theodolite apparatus mounted on a tripod to take angle readings between three points A, B, and C multiple times from both the left and right faces, and then averages the readings to reduce errors. The process involves setting the horizontal vernier to zero at each point, taking angle readings, and repeating between the three points from both faces.

    Horizontal angle measurement there are two methods

    Repetition method

    1. Theodolite apparatus
    2. Tripod

    1. Select a staion point A


    2. Place the instrument at point A and adjust the telescope to the left
    3. We make the horizontal reading at zero and Lock Vernia
    4. We define point B and take a reading is zero
    5. We Open the Vernia.
    6. We define point C and take the angle reading from the horizontal vernia .
    7. We Lock Vernia for the horizontal reading and back to point B
    8. We Open the Vernia
    9. We define point C and take the angle reading from the horizontal vernia
    10. Repeat the process 3 times
    11. We turn the telescope 180 Deg. to become the right face
    12. Repeat the same steps on the right

    13. We take the average left face with the right face
    We distribute the error in proportion to the number of angles observed
