Year 11 Physics Assignment

The accuracy of this technique is very low due to the fact that cell towers can support ranges of 35 kilometers or more.

If they do not, but are within the acceptable margin of error of ±20√4=±40’’, each angle is corrected to create a sum of 360˚. For this project, the angles added to 360˚ 00’ 10’’. After each angle is corrected, angle 412 is 78˚31’03’’, angle 123 is 99˚01’23’’, angle 234 is 92˚32’21’’, and angle 341 is 89˚53’13’’. After using the Total Station, the Auto level is used to measure the elevations of each point. The known elevation outside of Powell is 380’. The Auto level is placed between each point to measure the backsight and foresight. Once all the points are measured, all the backsights and foresights can be measured with the difference taken to find the error. With this project, the error was -0.128’. Next, the pacing between each point must be taken to find the correction for each elevation with the equation, (distance from known elevation/total level network distance) X total error. The total pacing for the project is 235 steps with a pace of 2.31 feet per step. After the corrections, point 4 is 379.384’, point 3 is 378.182’, point 2 is 379.093’, and point 1 is 379.645’. A transit is used to find the true north from the magnetic

The Global Positioning System (GPS) is a system of navigation based on the integration of 24 satellites, 21 working systems and 3 backups, that relay information regarding craft position and velocity to users (Colborn, 1992). First initiated as a program by the US Department of Defense through their Navstar system, GPS was deployed and fully operational in 1994 and speculations of the utility of this

He used a hand bearing compass, pointed at a lighthouse or some other landmark and looked across the lubber’s line into the bowl, taking bearings of two or more objects, and reading the direction or bearing of that object, off of the compass. Then, he plotted them onto his chart. Where the lines crossed, was where he was. It was that simple. The GPS was for his clients. It made them feel better, not him.

The development of the Global Positioning System, GPS for short, was accelerated by Sputnik in more than one way. When Sputnik launched, Guier and Wieffenback were able to measure the doppler shift in the signal that was broadcast from Sputnik and successfully estimate the location of Sputnik. After telling their Laboratory’s Director about their discovery they were granted

Ever since man has been observing their surroundings, there has been a desire to go to the far reaches of our earth and out of our earth. Global Positioning Systems, or GPS, has allowed an easier way for people to know where the user is on our earth and to know that we put something into space.

GPS gives the distance without calculation and gives you idea of the weather condition. Quadrant is a down grade to the Gyroscopic Compass. Quadrant helps you find the north but can be effect but earth magnetic field. The Gyroscopic Compass is always pointing to the real northern star and dont use the earth magnetic field to find the northern star. Sunglass was more harder to to keep up with time you had to turn the glass every hour. The ditigal clock is hand free and you dont have to turn it every hour. Columbus had to use his own eye site to delect something but he could only see so far. Radar of would delected something miles away without having to keep watch 24/7 of ships surrounding. Columbus got off course often and had to correct himself but with Long Range Navigation Columbus could of found where his Ship was and got back on course. If Columbus had a Depth Sounder he would of be able to see under the water to make sure he didnt hit nothing and even could see the fish under the water for Columbus could catch them for

This week around the time of the Atlas Five launch, the Colorado’s aerospace industry is celebrating a milestone this week, the twentieth anniversary since the Global Positioning System (GPS) emergence was announced at Full Operational Capability on July 17, 1995. On Friday, is the day twenty years ago, the GPS make its dent in technological history.

GPS is one of the tools that scientist use to predict volcanic eruptions. This allows scientist to check underground for small earthquakes. The GPS tool can also detect if the magma is overpressured. If the pressure of the magma is to high, its a signal of eruption. The GPS can also detect the movement of magma underground which can also be a signal. These are so things that the GPS can do to help predict volcanic eruptions.

Energy is a very important property, it can only be conserved. Energy can’t be created or destroyed, but it can be transferred between objects. Kinetic energy is in the form of motion, sound waves, and or heat. For example, kinetic energy could be the heat from the use of the phone during the day or as the phone falls to the floor. Where as potential energy is the energy that is stored for later use. An example of potential energy would be chemical energy in the battery of your phone or light from the screen of your phone. In addition, law of conservation of energy is energy that is not created or destroyed but just changes form. An example of this would be when you drive your car; you convert chemical energy into mostly mechanical and thermal energy.

When Hess decided to hold off on his geological study to be a reserve officer during World War Ⅱ, he carried equipment for sounding the ocean floor on his ship. This sounding gear bounces sound waves off the seafloor to determine the underwater topography. Today people use vessels like they did in the 1900’s, but today people use more developed tools. Today a person might use a GIS (geographic information system). This technology makes out maps, these maps show up on a computer screen.

The Troposphere has atoms and molecules which affect the radio waves between the satellite and the receiver. Due to the amount of gas present in this area group velocity decreases and the Zenith angle contributes to the troposphere refraction. The lower the zenith angle the more affected is the tropospheric refraction. Ionosphere and Troposphere has an influence on pseudo range and Carrier phase measurement because of electrons present in this region that obstruct the signal waves from the rover to the satellite, (Parker, 2003). Virtual Reference system with the GPSNET software is able to model these errors and thus the errors are reduced. The Troposphere is non dispersive for frequencies below 30 GHz, however the Troposphere adds a slight distance to the range measurement.

The Global Positioning System (GPS) is a constellation of twenty four satellites that can pinpoint any position on earth using a GPS receiver. Used to calculate exact position, speed and time, there are tremendous

A site, once home to industrial activity, has been marked as an area that may be causing environmental damage to a nearby river. Since the industry has ceased, all of the buildings have been removed and the only features of the site now lie beneath the surface. A brine tank is buried on the site although its exact location is unknown along with cables and pipes. It is possible that the tank is leaking, allowing brine to flow untreated into a freshwater fishing lake. The best method to discover if this is the case, is to use a GPR survey of the area to discover the position and condition of the brine tank. To do this, surveying will take place along lines with a 5m spread to be certain that the brine tank will be found. As the tank is known to be close to the surface, an antenna of a high frequency will be used. The survey will produce a radargram which can be interpreted for the final results. Following surveys such as boreholes

This essay examines the question: How does GPS rely on geometry and trigonometry now that there are satellites? Has the function of geometry and trigonometry in triangulation and navigation changed since satellites were
