Here’s a great app from DishPointer, released in August:
Very surreal, this is the next generation satellite finder: Point your iPhone anywhere towards the sky and see all the satellites lined up, on the live video screen! At a glance, you’ll see where the satellite is and whether any trees or buildings are blocking the line of sight. Think of multi-lnb dishes and now you know where to place your dish best. Doing a site survey and setting up a dish is going to be a piece of cake with this app. This is a truly useful augmented reality app for the professional and diy enthusiast alike.
The app uses the gps, accelerometer, and the compass of the new iPhone 3GS. Just move the phone up and down and left and right and the satellite arc will follow the live video on the display. The compass has a bit of a lag though, so when doing quick sideways movements the satellite arc is trying to catch up but then settles to the correct position.
If you’re in the satellite business, you know how valuable this can be. Available now — a steal at $20.
