The global positioning systems that have been invented are very useful to navigate where you are and in which direction you are heading. They are definitely more reliable than the compass bearings that are available in the market. The GPS is more exact and helps in navigation. It is portable and can be carried around with ease. There are people who need navigation especially the army as they need to be navigated through the woods when at war. It is very nice that you can hold a device in your hand and find out where you are and where you are going.

The signals get broad casted from the satellites helping in the process of navigation. The GPS is used by different people the pilots, in the cars, in different kind of transports. The army requires the GPS all the time as sometimes they get lost and do not know where they are and where they are heading. The GPS guides them through all the terrains and helps them in their job. There are many times when there are storms and bad weather conditions that make it difficult for the army to know where they are. There are maps which can be used but these maps do not help at times.

The maps are definitely helpful as well but in case you loose the map or it is not usable then you need to get the GPS as it will be more helpful and accurate compared to the map. The army relies a lot on the GPs and it would be very difficult or nearly impossible for them to survive without it. You will not understand how important it is to some people, if you put your foot into their shoes is when you will know how people survive on it.

Pilots do not get into their flight unless it has a GPS in it as they know how essential it is for them. There are bad weather conditions which they often face and for that the global positioning system is very essential to them as it is very accurate. There are many times when the pilot is in the air and cannot figure out where he/she is due to the clouding and at times like these the GPS is the only guideline no signals or maps can be used. In the earlier days people have had many bad experiences due to the navigator not working.
