Project EMMA Update – 10/07/10

We have been doing some heavy development on Project EMMA, primarily becuase it’s the easiest to do in our spare time. We now have functions for ZFS, Cron, Google Maps, GPS NMEA Data, Serial Interfaces, 3D Visualisation and have made the move to SVG for all of our graphing and image generation. The main reason for switching to SVG, is to move some load off of the server and onto the clients. This will also bypass some issues with browser caching.

I have also made some minor changes to the Project Auto Launch template, on the EMMA GUI. More GPS information is displayed, graphs are generated using SVG, and they are also reversed showing newest data from the left(this feels more natural when reading live telemetry from the plane).

The image shown is the new PAL interface. We reached a top speed of 41.11 kts (76.13kph / 21.15ms-1) that day, total flight time was 15 minutes, the battery was drained almost to half, which is what we expected from the 1350mAh LiPo battery. We should be able to achieve at least an hour of flight time, with our new 2600mAh battery.
