Introduction
Global Positioning System (GPS) is one of the most developed technologies in the sphere of navigation. A GPS is a satellite based navigational system that would help the users pinpoint the position of a location anywhere on the surface of the earth. From the network of Satellites that orbit the planet, GPS devices can define certain locations in terms of latitude and longitude. This information is benefiting people in many ways, for instance when one needs navigation, hiking and even emergencies. It is common for GPS to be installed on the smartphones, cars and other devices, which requires navigation. Implicit in GPS technology are vectors that hold key responsibilities of measurement of distances, directions and routes. This paper aims on describing vectors in GPS technology with the help of diagrams and examples, its properties and the way it operates.
Importance of Vectors in GPS
Vectors refer to variables that have a direction as well as a magnitude. This dual characteristic makes them best suited for representing physical quantities in navigation. As compared to scalars which only possess magnitude for instance distance, vectors offer more details on the movement and location.
Vector Properties: Vectors are employed in GPS technology to portray the following;
Position Vectors: These provide a relative position referring to a certain point of origin for instance a satellite or a station. For instance, suppose a GPS receiver is 5 Km north of the reference point and 3Km east of the same point, then the position vector can be P= (5, 3).
Velocity Vectors: These refer to the rate and the orientation of the movement. For example, if a vehicle moves at 60 km/hr in the northeast direction, the velocity vector both speed as well as direction is symbolized as V = (60 cos 45°, 60 sin 45°).
Displacement Vectors: These indicate the movement from one location to another, in other words movement from one point to another. If a vehicle goes from point A to point B, then displacement vector shows how far-A is from B and in which direction.
These properties are important for defining the movements and positions on the Earth’s surface, which in turn enable good navigation and optimization of movements.
Vector Diagrams
To illustrate the application of vectors in GPS, consider the following diagram:
In this diagram:
The origin is a starting point (0, 0), for example, a GPS satellite has its own origin.
The position vector is drawn from the origin to the position of the user or object in space with coordinates (5,3).
The user or object being located is noted at the end of the position vector and indicates the locality with reference to the chosen origin.
This illustrates the use of vectors to show positions in the GPS system and appreciates the role of magnitude and direction in navigation.
Vector Operations in GPS
Several vector operations are crucial for GPS viability as a navigation system:
Vector Addition: This operation finds out positions that are acquired when various movements take place. For instance, if a car goes 10 km north and 6 km east then the total displacement can be achieved by adding vectors. This can be calculated as follows:
Total Displacement = D = (10, 0) + (0, 6) = (10, 6)
When vector a is added to vector b, the magnitude of the resultant vector can be determined using the Pythagorean theorem:
|D| = √ (10² + 6²) = 11.66 kilometers
This addition makes it easier for the position of the vehicle to be determined to enhance planning of the route.
Dot Product: The dot product is used in ascertaining the relative change in direction during navigation among others since it unveils the angle between two vectors. For instance, if a vehicle has current velocity vector as V1 = (3, 4), and intended direction vector as, V2 = (1, 2), then the dot product will be given by.:
V1 · V2 = (3 · 1) + (4 · 2) = 3 + 8 = 11
The cosine of the angle θ between the two vectors can be derived from the dot product formula:
cos(θ) = (V1 · V2) / (|V1| |V2|)
This calculation is needed for tuning its navigation based on the current heading, which has to be corrected relative to a desired heading.
Cross Product: The cross product is an operation that allows determination of a vector which is orthogonal to two initial vectors. It is especially beneficial in several ways like computing for the attitude or heading of an aircraft. For example, let’s assume an aircraft is travelling along two vectors A = (1,2,0), B= (0, 0, 1), the cross-product C = A × B will give us the perpendicular vector. This assists in determining the aircrafts positioning in space in relation to other objects that surround the aircraft.
C = (2*1-0 * 0, 0*0-1*0, 1*0-2*0) = (2, 0, -1)
This vector defines in which direction the aircraft is positioned concerning the three axes in space which are crucial for modeling correct flight.
Component Form of Vectors
Vectors can also be described in terms of components, which are determined from the aspects of the horizontal and vertical components. For example, the vector v that defines an animal’s movement can be expressed as follows:
v = (vx, vy)
Where:
vx is the horizontal component.
vy is the vertical component.
This way these components can be given reasonable values and thus GPS systems can be used to make useful predictions. For instance, if a vehicle has a velocity equal to 60km/h and with direction of 30 degrees, then we calculate components as follows:
vx = 60 cos (30°) = 51.96 km/h
vy = 60 sin (30°) =30 km/h
These calculations assist in translating the direction and magnitude of vectors into better suited dimensions for efficient navigation.
Application of Vectors in Medical Robotics
In general, using vectors is crucial in the field of medicine, and it is crucial especially when it comes to robotic surgery. The velocity and acceleration of a surgical tool are highly important when making a surgical cut. As a student who dreams to be a surgeon, it is very clear that accuracy is of paramount importance when performing surgeries. Technological advancements in automating machinery have enhanced the efficiency and reliability of surgery operations.
For instance, robotic surgical systems can maneuver with tiny, precise motions, which contributes to small cuts and greater accuracy. Thus, the concentration on direction and length of cuts performed by the robotic instruments constitutes the essence of vectors within the human body. However, a distracted surgeon with low self-esteem in the operating room is equally dangerous for patients because a minor mistake may harm a patient by causing injury to a large artery or nerve.
Knowledge of vectors will enhance the surgical procedures since surgeons will be in a better position to maneuver through sensitive anatomical structures while performing surgery without being dangerous to the patient. The combination of vector analysis in medicine helps in demonstrating the universality and application of simple mathematical concepts.
