9. From a GPS base station, the location of a second point is determined using differential GPS as lying 3999.53 m east and 6982.47 m north of the base station. The GPS antenna is removed from the base station tripod and replaced with an EDM, which measures a distance of 8046.93 m to the second point. The GPS results are believed to be accurate to 20 cm in each component (east and north) while the EDM provides an accuracy of 10 cm. Provide the mathematical model suitable for adjustment of the second point's coordinates using a parametric least-squares adjustment. Is the model linear or non- linear2 What weight matriy chould be used in the adiustment2
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
