We are looking for 2 highly motivated European students to develop,
during this Summer, a relatively small piece of software to the highest
space standards, based on its (already developed) architectural design.
A full test bed is available. A first version of the code is meant to be
finished and tested by October, and should be operational in space in
2007. The internship will start ASAP (July 1st preferred), location near
Leiden, The Netherlands (Delta-Utec and ESTEC, the European Space research &
Technology Centre). The funding is 600 euro per month. Period July till
October, duration 3 months, can be extended to 6 months, which is

As you may know, YES2 is a small but highly innovative and visible space
experiment, that is currently being designed and built by students from
all over Europe for the European Space Agency, lead by Delta-Utec
( ) in Holland. In earlier phases the team was quite large,
~80 people, nowadays the team is more focussed and more like 25-30
dedicated students. YES2 is to be launched in 2007 and is approaching an
ESA formal CDR, where (for the first time for a student project) it is
attempted to follow ESA design standards.

The exciting and ambitious objective of YES2 is to deliver an innovative
re-entry capsule, Fotino, accurately to the ground using a 30 km, 5 kg
tether (cable) that is deployed in space, and slings the capsule back to
Earth, much like David's slingshot toward Goliath.

The YES2 design consists of 3 major pieces:
1- the tether deployer: FLOYD. A PC104 receives telecommands and sends
telemetry and controls the deployment by controlling a stepper motor,
based on length information coming from optical sensors. The PC104
communicates with EGSE (Electrical Ground Support Equipment),
RS422 for data, a UHF receiver, and a stepper driver.
2- the Fotino re-entry capsule.
3- the mechanical and data acquisition support system, MASS, which is
attached to Fotino until shortly before re-entry. It contains a
microcontroller that collects data from sensors and GPS and forwards it
to a UHF transmitter. This microcontroller also controls the release of
Fotino into a re-entry trajectory based on a timer.

Job description and requirements

- Job 1: Programming and testing the FLOYD PC104 code (C/C++), RTOS:
QNX+High availability manager, plus EGSE software. A functional
breadboard running DOS is available, including all algorithms and
relevant parameters. Requirements, architectural design and test plan
for the flight version is available as well, as developed by a previous
student. Experienced in C, C++; RTOS experience is requested, QNX and/or
electronics know-how is a pre.

- Job 2: Overviewing all YES2 software developments, documentation,
testing and verification of applicable ESA standards. Experienced in SW,
interest in space standards and quality control. You are likely to work
also on the coding itself in co-operation with the other team members,
especially Job 1.

- You will work in a local and close international team of about 10
excelling students and young engineers, in a professional space
environment, with experts in your field within reach. Of course a
co-operative and communicative spirit is required, as well as good
knowledge of English. Because the experts are usually busy and the
remainder of the team has other responsibilities, a high degree of
pro-activeness, initiative and self-management is required. You must be
meticulous and self-critical, and communicate uncertainties/problems
effectively to the team leaders.

- The infrastructure with the rest of the YES2 team (spread over various
universities in Europe and Russia) is well developed. The software team
is small, 4 people in all (including Job 1 & 2) and fully located in
Leiden/ESTEC, but you will interface with many students, locally and/or
through our web tools, Interface Document, meetings and teleconferences.

- Job 2 will be part of the 4 people strong "Tiger Team" at ESTEC, a
core group of students that oversees the development and quality of all
aspects of YES2. The design of YES2 is largely finished and many
breadboards and tests have been performed, but ESA standards have not
yet been reached. The Tiger Team is lead tightly by an ESTEC young

- Time-out for exams etc. is acceptable, if communicated well in

- The working environment is generally experienced as fun, rewarding,
professional and inspiring. It is a great first (or second!) step and
opening into the space world. A lot of hands-on work is going on in YES2
now, so much to see, and ESTEC of course has many other interesting
projects running.

More information? Send your CV and telephone number to Michiel Kruijff
whose contact details can be found on the website ,
and we send you a link where you can download a complete info package,
that includes ESA standards, info on QNX, breadboard code, architectural
design, test plan etc.
Also questions can be directed towards Michiel Kruijff. Location (ESTEC or
Delta-Utec), housing and travel reimbursement shall be treated on a case
by case basis.
