Sky Map application for Android
I've just installed and tried out Sky Map. This application shows what you should be able to see in the night sky from your current location and the direction that you are pointing your phone. I think it is using the network location to determine your location as after a few seconds I get a message stating that it is now using the name of my nearest cell tower as its location. The direction that the phone is pointed in must be determined from the built in compass.
It is hard to tell how well this is working as I'm in London and it is somewhat overcast tonight, so there aren't many starts visible. From using Sky Map (assuming that it is correct) I could determine which stars I could see, and it seems I could even see Saturn. I will have to try this somewhere where I can actually see a descent number of stars. Will try it again in Leeds at the weekend, and see how I get on.
