[Paparazzi-devel] Differential GPS through Paparazzi (James Maday)

[James Maday]

Hello Paparazzi fans-

I'm working with a team developing a UAV which will very soon employ the Paparazzi Autopilot (AP) for navigation.  We have only just begun programming our airframe.xml, but before we get far I'm hoping to answer this feasibility question: is differential GPS (DGPS) usable by the Paprazzi system for altitude measurement?

I've searched the mailing list and didn't find any previous talk of
using DGPS with Paparazzi, so I figured I'd poll the audience to see if
anyone has tried and can offer advice.  Thank you very much!

To answer my question here are some basic project details.  The UAV must maintain 10-15 feet (roughly 3 - 4.5m) above the ground following predetermined waypoints for 10 hours.  We have two sets of the TWOG with LEA_5H GPS device from PPZUAV.  We are using a laptop w/ Intrepid Ubuntu Linux for the GCS.  An example of a UAV that uses DGPS in its AP is the ScanEagle by Insitu/Boeing.  ( http://defense-update.com/products/s/scaneagle.htm )
