It is also true that how did you know the current locations when you yourself have not any sign of ideas about the current locations and how to know the current locations in the past? The GPS receiver inside your phone is smartly ask dozens of satellites that is orbiting around the Earth for positioning information. Currently there are thirty one GPS satellites orbits around Earth,. The question how does all these satellites determine your location?GPS satellites relatively know their location inside the space . If satellites can find the relative distances from the individual then it is further more precise and accurate information and for this the real test of accuracy could have been more precise and smarter . We get the surface of the sphere in the calculation not the surface of circle. GPS satellites continuously send out the radio messages with time and the positioning information embedded in them. GPS receiver is to pick up these messages and then calculate the distance from the satellite positioning system.
If the clock between your GPS device is slightly not accurate then you will find the distance of nearly one thousand to five hundred kilometres so for more precise information the use of fourth satellite is significant. Based on the messages of the radio signals from four GPS receiver, it will adjust the time of your GPS device automatically. The gathering of information is from all the satellites through various mediums make the data processing really slow. That is why the classification of many GPS enabled devices such that differential GPS and assisted GPS come into picture. Unlike sensors and accelerometers GPS devices cannot operate on its own.
We know how important is geo location and navigations is. It is the smart technology that will tell you where you are and it will show you the destination. In the past when we are searching for some locations then we are used to ask the local persons or the traffic officer to know the details. In case of tourists there are always the risk associated with it when you ask the strangers out in the road and in these case these just been catapulted to more and more severe conditions when you are being accompanying by the family and asking the stranger and there can be every possibilities of getting into the wrong informant and for this to find the real and reliable person in this regard is a he task and how manage it is the real matter and that to be considered fully.
It is also true that how did you know the current locations when you yourself have not any sign of ideas about the current locations and how to know the current locations in the past? It is the hoarding of the nearby market in that areas which you been to or some other possible ideas , if there is some coincidence that there is no market in that area and also there is no sign and bill boards and the street name’s colour is not visible, then what can be the solution during that time?
All these should not have been the problem in the modern times with the advent of GPS technology and many more mobile towers nearer to the vicinities. If you are at a cross section and want to know your location then what should you be doing in this juncture , Replace the landmarks with the satellites , it is the same age old technologies of detecting the land marks and signing them so that in the next time you will be at the same place as before. The tiny device the GPS embedded within the phone can have very much broader role of action and the way it will guide you it will have very high and significant variations.
The GPS receiver inside your phone is smartly ask dozens of satellites that is orbiting around the Earth for positioning information. It will need to have at least four satellites in its kitty and send and receive the data to know the exact location. Currently there are thirty one GPS satellites orbits around Earth,. They make two revolutions around the each day. The question how does all these satellites determine your location?
GPS satellites relatively know their location inside the space. They are designed to behave as the reference positions as these are all very complicated technologies. It is like determining the geometric positions through various fine prints and different logical theorems. This is like determent the areas of the circle in and around five kilometers but these are not enough , more references needs to be added further to know more precise location awareness so that most of the definitions of determining the locations could have been more correct and precise.
If satellites can find the relative distances from the individual then it is further more precise and accurate information and for this the real test of accuracy could have been more precise and smarter. Now we reach from circle to point but one big stumbling block is we are considering the two dimensional aspect as it can be somewhat misleading with comparison to three dimensional approach.
Earth orbits around three dimensions and with the consideration of two dimensions the one latitude is missing in the calculation of geo stationary orbits. We get the surface of the sphere in the calculation not the surface of circle. This is why the importance of more than one satellite is being important here as when we determine the location then the cross section of two satellites gives the circle not the sphere and this is helpful and more accurate and precise. With three satellites the intersection circle of all these will give you two circle and that will have two points and then we could find the distance from the fourth fixed points.
GPS satellites continuously send out the radio messages with time and the positioning information embedded in them. With the advent of three measurement that narrow down the scope of errors significantly. GPS receiver is to pick up these messages and then calculate the distance from the satellite positioning system. It is also obvious these radio messages travel fast. These messages will take approximately 0.0067 seconds to reach to earth.
If the clock between your GPS device is slightly not accurate then you will find the distance of nearly one thousand to five hundred kilometres so for more precise information the use of fourth satellite is significant. Based on the messages of the radio signals from four GPS receiver, it will adjust the time of your GPS device automatically. In this way the positing of your stance is now located but there more works to do after it.
The speed of light actually varies depending upon which material it is passing through. The gathering of information is from all the satellites through various mediums make the data processing really slow. That is why the classification of many GPS enabled devices such that differential GPS and assisted GPS come into picture. Unlike sensors and accelerometers GPS devices cannot operate on its own. The information it received is just a bunch of additional information and all these needs to be processed and materialized to the smooth ideas and understanding of persons. That is why more and more reverse geo coding and geo coding servers and especially is being built by companies like that of mobile manufacturers in order to give access their clients the relevant and significant information.
This is to find out where you are and which location you are currently in. There are many services out there with which you can attach your social networking profiles so much so that when you reach that place this will show automatically to yours social networking profile that you have been there . When you get into foursquare you will be surprised by the amount of offering given to you by different shopping malls and plazas and for this you do not have to go nearer to the shopping arena or search inside the news papers. It is right as you can know all the information due to the fact that foursquare uses your location information to get the best deals for you, is not this is the fantastic ideas? This is the road to innovation strength with this numerous other pieces of data you have access to as smart phone user , the possibilities are endless.
