Smart phone IRS ?
Just a hypothetical one (after a conversation in the pub last night)
Given that the latest smart phones come with accelerometers and gyros, if someone had the inclination and knowledge, would it be feasible to program an app to work like an aircraft IRS ?
I'm imagining putting in my start lat/long in (manually or via phone gps) and watching it give me the phone's current position, velocity and attitude.
