Global Ship Tracking Essay

From the essay, it can be noted that GSE and GPS have multiple similarities and differences, which sets them apart. More so, GSE covers the gaps, which were left out in the in GPS by giving a more detailed

The search for a system of measuring latitude and longitude began in ancient history, and took centuries of study until the eventual invention of the marine chronometer. A chronometer is a mechanical timepiece that provides the correct time at a reference location. Several refinements of the original proposal of the marine chronometer were required until the mid-19th century, when a device suitable for nautical use was discovered. Throughout history, hundreds of ships were wrecked or lost at sea due to errors in navigation until the introduction of chronometers, which allowed for determination of longitude by celestial navigation. This major advancement is required to navigate long voyages overseas where electronics and communication are not an option, allowing for safe and reliable international

After the trial period a company will be chosen to outfit the entire fleet with the tracking device of choice. This would be done in waves because we couldn't afford to not have access to the carts for a day. This process would take place over a series of 4 days, where each day roughly 20 carts would be outfitted with a GPS tracking device each day. This will preferably be done during the week because this is when there are less tee-times and less carts are required.

Lighthouse provides a ship tracking service for shipping companies to locate their ships at sea, as well as knowing their speed and the weather they are facing. Lighthouse does a contract for the delivery and installation of the physical device that is capable of achieving this through a tracking service that calls for a second contract. The price for the dedicated hardware (exclusive to Lighthouse services) and installation is a single nonrefundable amount of $10,000 payable at completion of installation and acceptance by client. When this is done, the location service can be provided. The service contract which is generally for one year is paid monthly at $300 per month. Customers may cancel the service contract at anytime.

My explore pt is GPS, gps is now very useful in our daily life, it is used to navigate, and in our modern life there are several types of GPS that be applied in many different ways like meteorological satellite, and of cause navigation satellite and so on

NASA Space Network has been providing a global communication service from early 1980’ [1]. The main function of the space network is providing tracking and data transfer service between user platform and the mission operation center . The Space network consists of two segments, which are the space segment and the ground segment [3].

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

In 1960 a scientist by the name of Dr. Ivan Getting left his position at Raytheon Company, and armed with the knowledge of what was at the time the most advanced navigational technology in the world, he began developing the Global Positioning System. Together with a team of aerospace engineers and scientists, they started getting into the three dimension global positioning system concept. In 1957, at the start of the Cold War and the Space Race, the U.S.S.R. launched Sputnik, the first Soviet satellite. While observing Sputnik, U.S. scientists found out that they could track the satellite’s orbit by listening to the changes in its radio frequency using the Doppler effect, a technique that had previously been used to describe why the pitch of a car’s horn changes as it speeds away. In 1960, the knowledge gained from tracking Sputnik, the U.S Navy was able to launch transit, the first satellite navigational system, which was used to help guide the Navy fleets of missile submarines. In 1967, the U.S. Navy developed the Timation technique, a system that used a highly stable, synchronized clock in the satellite, a technology on which GPS was dependent by 1974, the first clocks were put into orbit. By 1978, the U.S. military launched the first four GPS satellites. Until 1983, GPS technology was available for U.S. military use only, until a tragedy occurred that the benefits of GPS technology could no longer be restricted from civilian use. In 1983, a civilian Korean Air airplane with 269 passengers, was shot down after entering Soviet airspace killing all passengers. In response to this tragedy, President Ronald Reagan said "that when GPS technology was operational, it will be free and available to the world". On Feb. 14, 1989, the first satellite was launched. On July 17, 1995, the GPS was complete. This system consists of 24

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.

Air travel has been massively impacted by GPS. Flights are currently tracked by radar18 which mostly works well over well-populated areas but can be problematic over remote, mountainous areas where there are less radar stations or over the ocean. Planes must stick to established routes in these areas and remain more

Sir Corbett’s aim was control of the sea by interrupting via interceptions and/or naval blockade.9 Without shipping communications and the normal flow of commerce, the enemy is forced into an ill-prepared response. Again, interruption of communications in space could be an effective tool against the enemy. However, one would need to be careful not to disrupt their own communication with the global connectivity that has happened through space domain technology

To start off, there are three main weapons systems aboard the Nimitz carriers. Most important are the NATO Sea Sparrows, a surface to air missile system. This radar guided weapon is short range and uses a homing system to readjust its path mid-flight. Although the range and speed are classified, it is known that the missile is 12 feet long and has a cylindrical body with four mid-body wings and tail fins. This system is mainly used for self-defense against a variety of surface and air threats. Next, are the RIM 116 Rolling Airframe Missiles, designed to destroy anti-ship cruise missiles and other various air or surface threats. These missiles are lightweight and have a quick reaction, all the while traveling at supersonic speed. Finally, CVNs carry the Phalanx CIWS. This, too, is radar guided, fast paced, and protects against anti-ship missiles. It can fire 3000-4500 rounds per minute and can fire at small or close targets due to its Electro-Optic sensor (“Fact File”). Continuing on with the assets of the ship, it is essential to cover the sensors, or electronics, of the carriers. There are four main components of the platforms electronics. First are the various underwater torpedo systems including SLQ-25A, SLR-24, and LEAD, and more. These systems perform activities ranging from Acoustic Decoy to alerting and diverting. Next is the air search technology, combining

Navigation has always played a key role in all aspects of human life. Although modern technology has simplified travel and airplanes are used constantly, ships continue to be an important part of trade and military systems today. This was especially the case around the seventeenth and eighteenth centuries. Colonialism was built on navigation and whoever held the greatest naval power could gain the greatest control. However, because of the difficulties that came from calculating location while at sea, navigation became the greatest scientific challenge in the age of sailing.

It stands for Global Positioning System, and it's become more sophisticated in recent years. A network of satellites spin around the earth. The

Such tracking system is capable to provide observation of strictly round area with certain diameter and detecting of the targets (vessels) in determined sector (sectored detecting of target is delineated in the third subsection) of this round area. This system can be exploited with different quantity and combination of observation beams as follows:
