This simplified 2D example will demonstrate how GPS uses trilateration to pinpoint an unknown location. Once a receiver has "locked in" onto a satellite, the unknown position may be anywhere within the radius of 1000 km of satellite one. The receiver picks up a signal from a second satellite and calculates the range as 1200 km. The position has been narrowed down to two positions; where the ranges intersect. If the receiver picks up another satellite, the unknown position can be found by calculating where all three distances are possible.
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

Many accidents are caused by distracted drivers who are attempting to punch in the address while driving. Making sure that you have added the address correctly and knowing the general route before driving is the first step to proper use of your GPS device. Take advantage of GPS systems that use voice. Using this feature helps one to keep their eyes on the road, avoiding unnecessary distraction by looking at the GPS device. Another safety tip is to put your passenger in charge of the directions. A passenger can be used as an alternative to voice directions, so one can keep their eyes on the road. Understand there may be changes not reflected on the GPS information. It is important to pay attention to the roadway and not depending on the device because maps may not be updated.It is important to understand how to operate your GPS device and to take advantage of safety features such as voice control. YouTube has many videos that may walk one through the steps to understand how to use your specific GPS.The principal rule of safety when using the GPS device is to always keep your eyes and the road and not your device. Using the GPS device can be a great tool to get you to your destination safely, especially when used

There is no longer a need to be a skilled map reader as GPS can provide directions anywhere to the most unskilled navigators, whether it be to a hospital for emergency treatment or a local point of interest for tourists and finds the shortest route16, making travel easier. GPS can also be used to track others16 which has made it far easier to find missing persons as with GPS becoming prevalent in phones and car, almost anyone can be tracked by one of these items. The impact of GPS on travel is unfathomable, it has made the method of navigation that was used for centuries almost obsolete and opened up the world to
GPS software can be installed on all devices so that if they do go missing they can be found.
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
Some people may say that using their phones while driving is essential to know the directions for example, using google maps. However, this could be solved by looking at the map before starting the
Lots of people around the world use GPS on their phones and in their cars. Before the Space Race and GPS’s, it would take people much longer to get to their
If you are using a phone then those don’t really apply because the phones are updated often. At the end of the day though this is mostly operator error. If you see signs that are telling you not to go down the road or you see a sign that says the road is not suitable for your vehicle, then that is on you. If you don’t follow the GPS when it tells you to go down the road and you go another way, the GPS will reroute and give you another way to get to your destination. A GPS is just another piece of technology, which will never be perfect, and the user should know that when they go to use
With new technology being introduced on almost a daily basis, it needs to be decided what ways are safe to use that technology. Advanced technology has created an abundance of things that can be used while driving. The most popular technology used while driving is the cell phone. Although it was invented in the 1970s, the cell phone did not gain momentum until the 2000s. Even during its first days, the effect of a cell phone distraction was already in the spotlight (Brown, Tickner & Simmonds, 1969). Allowing people to talk wherever and whenever, it became important to ensure this technology was not harming society. Driving is a complex cognitive task. Since its use boomed in the 21st century, several road problems and accidents were linked
Today’s day and age maps have basically have been replaced by the technology of global positioning systems with allows for a little safer driving due to the driver is not trying to read a map when they are operating their vehicles but with the new technology comes new problems. This new system can allow the driver to fallow a voice but when the system is not up to date it cause drivers to have to make quick lane changes and exiting that is making them drive in a reckless manner. Most of the Systems are distracting because people will start driving they then turn on the system and try to input the address they need to get to which sometimes involves leaning in a distracting way and also taking their eyes of the road and mind on a different matter.( AwartickPublished) during the new age of occupations companies have now put computers in the cars to help people with all that needs to get finished on time and to allow to finish the jobs they are required to do, this is many seen in government vehicles
Since the advent of humanity, nature has always proved to provide us with sustenance and opportunities for adventure. Yet, it was not only the lack of funds for urban adventure that drew millions of millennials into the woods. In May of 2000, GPS had a revolutionary improvement. This advancement of the global positioning system allowed users to engage and control selective availability, enabling them to pinpoint their exact location and other select locations. The White House stated that, anyone could use GPS to isolate, "the location of items left behind for later recovery.” Thus, sparking the origin of
Drivers can practice several safety tips to help them navigate the road more safely. First, use your cell phone for emergency situations only. Pull over to the right shoulder to make the important call. Next, limit the number of passengers in the car. It is a good idea after a football game for a group of teenagers to drive around town texting and driving. Driving with friends can create a dangerous driving situation because drivers are focused on their friends rather than on the road. Finally, avoid eating while driving. Food spills are a major cause of distraction. Pick up a big Mac and fries on your way home and eat it while you navigate the heavy traffic. Finding the extra fries in the bottom of the bag will taste good as you rear end the car stopping suddenly in front of you.
There are 24 satellites that circle the earth every 12 hours. These satellites are split into six groups of four and each group creates an orbital plane. These six orbital planes allow the satellites to move in a way that covers the earth completely. GPS satellites transmit signals to equipment on the ground. An example is a GPS receiver (GPS receiver can only receive the signals form the satellites but they can’t transmit any signals). The receivers work best in an open outdoor area where there is a clear view to the sky. At any time there are always four visible satellites. The GPS receiver can calculate how far each satellite is based on the time it took the signal to reach the receiver. Using the distance from each satellite that the receiver calculated it could then use a process called trilateration to pinpoint the location of the receiver [1].
Radar ranging is used to find the distance of the planets which are near. This method works by striking a beam of radio waves towards the object, the radio waves after striking the object will come back as echo. So, the time taken by the radio waves to come back in the form of echo can be used to find the distance of the object.
Once a driver gets on their phone, they also may decrease in speed because they are not focusing on the speedometer, which could lead to other drivers becoming agitated. Then the other drivers may exhibit road rage which could become dangerous to others on the road. A driver’s focus should always remain on the road. If one is on their phone they cannot see or hear what is happening around them. A driver being on the phone while driving is one of the biggest distractions drivers today face.
GPS has made our lives so much easier. We don't have to print out directions before heading to an unknown address. GPS-enabled devices we carry with us daily allows us to travel freely without worrying about getting lost. There are also a number of GPS devices to help us keep track of our children. It's a dangerous world out there, and at any moment, we might need to know where our children are located.
