Analytical Graphics Inc. (AGI) has just released a free Satellite Tracking application on the Droid App Store. It's called "Satellite AR" (Augmented Reality). We are trying to create more buzz about our new Service Oriented Architecture capabilities.
The application allows users to point their Droid up at the sky and see satellite positions and orbit tracks superimposed over a simulated starfield. It works much like Google Skymap only it focuses more on the satellite tracks than working as a skymap. It will even give you estimated wait times for when satellites are due to rise over the horizon and is color coded to indicate whether a given satellite is in sunlight (visible) or not!
Data is taken from current Two Line Element sets from the Celestrak repository and propagated on our server to publish the satellite tracks to the user's phone based on the phone's current location. Data is available for a wide variety of satellites: GPS, Iridium, Weather, ISS, Debris, etc
I have already been able to go out at night and identify real satellite passes with it, so this isn't just a dinky little app. This is based on professional astrodynamics software and current space data.
