MaqSat H (Maquette Satellite - Haute) is a dummy satellite full of instruments to measure environment of launch.
The ARIANE 502 payload consists of three components: The lower Instrumented Platform (MaqSat B), the upper Instrumented
Payload (MaqSat H) and TEAMSAT (Technology education Experiment Added To MAQSat) (various experiments of European universities)
which is added to MaqSat H. The platforms are developed, manufactured and tested by Kayser-Threde, Munich and correspond to
about 90 % of the total payload mass.
MaqSat H, 2290 kg in mass including TEAMSAT, 350 kg & 5 m in height, will use 34 sensors to measure acceleration,
vibration, shock and acoustic noise at different locations. On an instrumentation plate flight data (32 Mbyte) will be
recorded within the first four minutes after ignition. Immediately afterwards, the data will be transmitted down to Kourou
within the following 4 minutes. The MAQSATH structure itself, including a simulating solar panel, will fulfill various
frequency and stiffness requirements and has the dimensions of a typical large comunications satellite. The evaluation of the
flight data will result in understanding and validity of the environment requirements for future satellites launched on
Ariane-5G.
After injection into GTO, MAQSAT-H was jettisoned. Afterwards, the ESA experiment TEAMSAT began to operate. TEAMSAT
ejected later the YES subsatellite, which was originally a tethered experiment, but for security reasons, the tether was not
used.
Teamsat was produced in 7 months at ESTEC.
Experiments:
Orbiting Debris Device(ODD) - Automation & Informatics Department, ESTEC.
The MAQSAT-H satellite is painted with contrasting patterns (75% white and 25%
black) to support testing and calibration of ground-based optical and radar
stations in Europe. The contrasting paint should also allow detection of the
rotation or tumbling of MAQSAT-H. Additionally, surface paint degradation will
be studied.
Autonomous Vision System (AVS) - Technical University of Denmark. AVS is a
camera which automatically recognises and tracks stars or non-stellar objects
(such as satellites). AVS can be used to identify specific stars, determine the
attitude of satellites for navigation purposes and acquire images.
Visual Telemetry System (VTS) - MMS Bristol (UK) / IMEC and OIP (Belgium). VTS
is an imaging system to monitor spacecraft activities such as the operations of
critical mechanisms. TEAMSAT hosts a system of three cameras and a master unit
to provide compressed image sequences of the fairing opening and satellite
separations.
Flux Probe Experiment (FIPEX) - University of Stuttgart. FIPEX will measure the
concentration of atomic oxygen at altitudes up to 1000 kilometres. Atomic
oxygen is known for its erosion effect and degradation of optical surfaces and
lenses.
