What is meant by a “satellite station”? Explain briefly (16) 4. What are the different corrections to be applied while measuring baseline in geodetic surveying? (16) 5. A steel tape 30m long, standardized at 10 oc with a pull of 100N was used for measuring a baseline. Find the correction per tape length, if the temperature at the time of measurement was 20oc and pull applied was 150 N. Density of steel = 3000 kg/m3. Weight of tape=5.88N.
