A total station integrates several functionalities to perform various surveying tasks. Which of the following features is NOT typically integrated into a total station's design? 

Explanation:

A Total Station is an advanced surveying instrument that combines various technologies for measuring angles and distances accurately. However, not all features are typically integrated into its design.

Analysis of Options:

1. Doppler radar for atmospheric compensation  (Not integrated)

   • Doppler radar is used in meteorology and satellite tracking, not in total stations.

   • Atmospheric corrections in total stations are generally done using temperature and pressure sensors, not Doppler radar.

2. Theodolite for measuring horizontal and vertical angles  (Integrated)

   • A total station includes a theodolite to measure horizontal and vertical angles.

3. EDM device for measuring distances  (Integrated)

   • Electronic Distance Measurement (EDM) is a fundamental part of a total station, used to measure distances accurately.

4. GPS receiver for real-time kinematic (RTK) surveying  (Possible in advanced models)

   • Some modern Robotic Total Stations integrate GPS and RTK for precise positioning.

   • However, traditional total stations do not rely on RTK GPS for primary measurements.
