You should go talk to your Mentor/supervisor. Hopefully he can arrange
some basic training on how to use all these tools. Maybe you need to
make contacts with ESA or Gaisler. 

My opinion is that you need a professional support contract from
somebody who actually knows this system and can teach you the basics.
