The Correct Option is A

Solution and Explanation

DGPS (Differential GPS) positioning is a method used to improve the accuracy of GPS measurements by using a reference station to correct errors in the GPS signal. DGPS primarily helps in correcting errors caused by atmospheric conditions, such as ionospheric and tropospheric delays, which can distort the GPS signal. Step 1: Understanding the errors in GPS positioning. - Atmospheric error is caused by the ionosphere and troposphere affecting the GPS signal. DGPS corrects these errors by using a reference station and applying the necessary adjustments. - Multi-path error occurs when the GPS signal bounces off nearby objects, leading to inaccurate measurements. While DGPS improves accuracy, it doesn't directly mitigate multi-path errors. - Cycle-slip error occurs due to sudden changes in phase in the signal, often caused by satellite signal loss or interference. DGPS does not specifically address cycle-slip errors. - Topographic error is related to the terrain and obstacles that may obstruct the GPS signal, but DGPS doesn't directly mitigate topographic errors. Step 2: Conclusion. DGPS effectively mitigates atmospheric errors, making option (A) the correct answer. Thus, the correct answer is (A).
