Question 6. The Global Positioning System (GPS) is the most widely used GNSS. In point form, briefly answer the following questions: i. Why is it necessary for a GPS receiver to observe at least four satellites in order to reliably measure its location on Earth? ii. Approximately what accuracy (horizontal and vertical) would you expect to achieve with a single, low cost, handheld GPS receiver? iii. Explain why differential GPS methods can be used to improve the accuracy of GPS measurements.

Three vessels P, Q and R start their voyage from a station three different directions at the same time. The speed of all the three vessels is 35 knots. Their bearings were observed to be N 60°E, S 35° E and S05° E. After two hours, the captain of vessel Q determines the bearings of P and R w.r.t. his own vessel Q. There after, he calculates the distances. What are the bearings and the distance as calculated by captain of vessel Q? Solution: 11.114

Sir Alfonse sent out five students to measure a distance between two points marked on the ground using their pace factor. The students came up with the following five different values: 50.13, 47.90, 51.04, 50.47, and 48.22 meters. Assuming these values are equally reliable and that variations result from accidental errors, determine the most probable value of the distance measured.
