The guys that make Sky Safari, a very full featured planetarium for iOS and Android devices have come out with a new program specific to track satellites. It's pretty good, there's a few things that I'd like to see, but for a 1.0 app, it's easy to use. It's also 40% off right now...I'm not sure it'd be worth the full price, but it's a good bargain now. http://www.southernstars.com/products/satellite_safari/index.html Dan -- Sent from an iPad. There should be less mispelings, but more errors.
