Just wanted to share some progress on an iPad Ground Control Station app I've been putting together for a little while. Here's a quick introduction:

As the video shows, the (non-jailbroken) iPad is hooked up to a Digi XTend radio modem via a RedPark iPad-Serial cable and a RS232 Shifter, with the radio modem powered off a UBEC. It communicates with the APM via MAVLink just like the regular APM Mission Planner.

Have also used the iPad-Serial cable with a XBee and XBee Explorer Serial board with my other UAVs, which makes for a simpler hook-up.

Just a personal project at this stage, particularly as use of the RedPark cable limits the redistribution options available (i.e. not permitted on the App Store at present), but have a laundry list of features I'm hoping to add over time, and we'll see what happens on the device interface front - would like to make the app accessible to all if there's sufficient interest.

Thanks for reading - looking forward to any comments you might have!
