JP Aerospace - More GPS Antenna Testing, Big Drafting

More GPS Antenna Testing

We still have not been able to replicate the satellite drop out we saw on Away 35. Everyday the test rig is powered up and we fly a simulated mission for three hours. All of the big problems have been ruled out. The hunt is now on for something subtle. On the plus side our GPS antenna knowledge has gotten a big boost.

Big Drafting

Last night I felt like I was in an old Land of the Giants TV episode. We are drawing a 18 foot wide ellipse on the floor. Big paper, big straight edges and a huge string “compass”.

We are starting to build the ribs for the Ascender 100. They are elliptical air beam structures. This follows on to our earlier air beam work, http://www.jpaerospace.com/whatsnewjan-feb-mar07.html

The air beam rib is 18 feet wide and seven feet tall. Our printer don’t handle paper that size, hence the drafting on paper rolls on the floor. We got the axis and the first ellipse layout out last night. We should be ready to cut fabric by the end of Saturday.

Please feel free to discuss this topic further in the forum or chat…
