After you have read the article in your book about how a GPS works on pages 6-7, read the website that is attached below. I would like you to discuss the following question: Why would different countries have different GPS navigation systems? If the entire planet could utilize one, what is the advantage? Also, if sending more satellites into orbit, could this interfere with our GPS system?

I think that different countries would have different GPS systems so that the measurments can be more accurate all the time. I think that if a satellite is too far away from a certain area that it wouldn’t be able to do it’s job as efficently compared to one closer to the country. Also, the satellite could be programed more effectively by people that know the country better. I do believe that it would be much better to have just one satellite in space that could work for GPS systems all across the world because that would create less competition amongst countries as to who’s science program is more developed. I do think that there is a possibility that if there are too many radio waves being sent out from all the satellites that it could interfere with our GPS systems but I don’t think that this will happen. If it does though that would be a very large catastrophe.
Well politically, GPS can be used to monitor devices (and their owners) all over the globe, a reason why one country would like to use their own system might be so that they don’t have to rely on another country to get the information. Now this may provide many other benfits that were not originally intended. One might be the satillites will be less likely to become over-crowded, new devices gaining GPS each day and its hogging up the bandwidth. Another could possibly be with more satillites in the air, new devices could possibly talk to more satillites providing a more accurate location. Now whether they could interfere with other satillites is another concern, as long as the frequencys are different they shouldn’t provide too much interference. (Sorry, if this has spelling errors, I’m on my phone in the car on the way to a EKU..
Different countries have different navigation systems because they use different units of measurement. Also because it helps the distance being traveled be more accurate and precise. If all the countries could rely on one satellite it would eliminate the factor of competition all around the world. There would not be the competitive factor between countries when it comes to who’s science program is further developed and goes more into depth. In my opinion I think it would take a large amount of satellites to interfere with the GPS systems. I do not think this will ever happen in our society today. But if it did, i know a lot of people would be lost, I know I would be. My GPS is my best friend (:
I feel like they would all have different GPS systems because it would make things more accurately. I wouldn’t want something focusing on China and the US giving me directions because something could go wrong, because usually it does with technology and then it would mess me up. It’d be focused on one country only, instead of the others that they would want to be tied in with. The only thing I could think that would be an advantage is to make the countries to get along together and make programs and information for better. And I definitely think that things could go wrong with more satellites in orbit. Just like Alexis said, that if there are too many radio waves being sent out, that it could interfere, and I agree 100%.
I’ve actually thought about this before. I would assume that a every country would have their own GPS system, as a GPS device floating over the US wouldn’t be as accurate aiming at France, as one over France would be. The actual difference on the ground could change from 5-10 meters off to 20-30 meters off. While that IS a rough estimation, it still shows my point. If the entire planet got together, and decided on just one GPS device, one of the only and main benefits I see is that you could possibly have less satellite’s floating around in space, therefore reducing clutter and maybe even interference, if it ever happened. As stated before, lots of satellites in one area could possibly interfere with each other, causing massive mayhem on the poor folks who happen to be using a GPS or other device. Sending even MORE up, in my opinion, would just increase the affect.
I believe different countries have different GPS systems because a GPS system that is over the U.S. would be more accurate for U.S. than a GPS system that is over Germany. Also i dont think governments want other countries using their system because they might be hiding something …. Osama. Which is information they don’t want to provide for others. i don’t think using one GPS system would be beneficial except for keeping our space cleaner and less congestive. if we were to send more satellites into space i believe it could cause a lot of interference among our satellites already put up.
I agree with everyone on how different countries have different GPS systems because they are more accurate, but I also think it is a security reason. If every country had the same access to one then think of how it could be used for spying or attacks on other countries. Now of course there are positives to having one united system, such as being able to pin-point somewhere half way across the world. Governments could use at well, but for good and purposeful reasons. If we send more satellites into to space that could be both beneficial and harmful at the same time. Perhaps we would get more accurate and faster readings, but then we would have many more satellites orbiting around Earth that we would have to worry about. It could definitely interfere with our current system, causing glitches that come with new and improved technology.
I agree with Dishman and Cayli on why countries have their own GPS systems, for the reasons of accuracy and security, considering how heavily we rely on technology, this would be just another open door for threats to us. The benefits of one system for everyone, would be that no matter where you went that GPS would know how to get there and the best route. I think that the main problem if we continue to send satellites into orbit is both signal interference, and the satellites running into each because of the large amounts of satellites in space.
Different countries would have different GPS systems because some countries are more advanced than others. Another reason for different systems could be because of the fact that most countries don’t want to share with enemies. If the entire planet utilized one GPS system then different technologies could be combined and the accuracy of the units would be greatly raised. Sending more satellite units into space could interfere with other units because it could disrupt the frequency or even the possibility of satellites coliding.
Different countries I believe should have their own GPS systems because of a case of national security. If all countries used the same satellites then it would be easy to use one to take away a country’s home field advantage in a war. There would be benefits though to having all countries share one system because then there would be less interference between all of the satellites and there would be less of a chance of satellites damaging one another. Yes sending more satellites into space would definitely cause interference because there would be a better chance that signals could start intersecting and messing up each others GPS signals.
I think that different countries have different GPS systems because they would be more accurate that way. It would be because the satellite would be closer to the country that the system is for. It would be more hassle and not as accurate like if the satellite was by China and you were in United States. It is also better for security because the countries have differences in technology and other countries might have the technology to hack them and get info on the other countries. If the entire planet had one GPS system then I think it would just be too much info on the satellites and the accuracy won’t be as good. I also think that too many satellites are there then it would interfere with our satellites. The radio frequencies could interfere with ours and mess everything up.
Our countries are very competitive with one another. Although the different navigation systems all have the same purpose, countries don’t want to make it look like they’re copying off another country. So they just change the name of it because they think it’ll actually make a difference. In addition, all the countries have their own satellite system. Maybe the navigation systems from different countries get their GPS information from their own countries satellites. One advantage of having one universal navigation system is that it would work anywhere in the world! It would save the tourists a lot of trouble. lol. Also, maybe if the different countries worked together to make one universal navigation system, it would release some tensions between countries that don’t get along too well together. I do not think that sending more satellites into orbit would interfere with our GPS systems. In fact, I think it would make it more accurate.
i think that every country wants their own GPS system to ensure better coverage and accuracy of their own country. Also for the security of having a GPS system that doesn’t rely on another nation’s satellites especially during wartime. An advantage would be that people would have an even more accurate directions all over the world. I think that more satellites wouldn’t hurt the GPS system as of right now, but we would want to be cautious of how many we are sending up there or else it could become too congested to be any help to people.
