+The Imaging and Tracking Payload Unit (ITPU) is the scientific payload of the airship, and will be independent of the airship project to a large extent.
The purpose of IPS is to take aerial images from different positions, acquire accurate position and attitude data and use those combined information to create aerial image maps and extract further information from the images such as terrain height, 3D object recognition and possibly image-aided attitude control and path planning.
This could be used as a learning platform to simulation environment for Low Earth Orbit imaging.

\item Communication system: Attitude data and spacecraft telemetry will be transmitted to ground.
We try to achieve high bandwidth transmission that could even allow for image downlink.
\item Image processing software:
-Image matching and evaluation will be done on a standard PC after payload recovery or online if the transmission rate can be made sufficient.

There will also be a groundstation that communicates with the spacecraft during flight.

The fused information will be updated in real-time and stored together with each image snapshot.
+For development of the software, a simulation module will be written thats feeds simulated measurement data into the fusion algorithm.
+By this the performance can be quantified and development gets much faster than with waiting for actual measurement data.
