How is satellite navigation used within the public services?

I am doing coursework and need to know how satellite navigation is used within the public services. Public services being like the police, fire, ambulance, army or voluntary alternatives to these.





I also need to know how a fax machine would be used and why.





Thanks|||SatNav would be used in Police cars, Ambulances, Fire Engines so the users know where to go. If the services get an emergency call they will get the location from the call centre operator, they will then proceed to that location, if they don't know where it is they'll tap what the call centre operator told them into the SatNav in thier vehicle and away they go. The army also use SatNav to locate certain points on a map where they would like to go or to drop airstrikes or missiles onto the location. Nobody uses fax anymore, e-mails how it's done.|||well take for instance BUSES? most buses now are not only video linked,they are fitted with trackers by Satellite,not only for management to know where you are,but for the customer,if youre waiting for one you can now text the operator to find out how long the bus will be..obviously depending on traffic,untill it reaches your stop.thats one example.





basically a fax has been over ruled by e-mail,exactly the same principle,sending a document.|||Well all the others have explained the Sat Nav to you so I wont bother, but I afraid a lot of ignorance does show regarding Fax Machines.





Not everyone has computers or printers etc but they still buy and use Fax Machines instead.





With a Fax Machines you can send a load of documents especially legal ones between offices and courts or even hand written notes for the price of a phone call. Some of them you can also use as a photocopier.





Here are some examples of different Fax Machines.
