TET Customer Days 2013 on March 21 - 22
It is a great pleasure for us to conduct the TET Customer Days 2013 on behalf of the German Space Agency DLR.
This third event will take place at the German Space Operations Center (GSOC) in Oberpfaffenhofen near Munich on March 21 - 22, 2013.
The TET Customer Days 2013 will provide information on the on-going successful TET-1 mission through current results and feed-back from the experimenters. Potential payload customers for the next mission (TET-2) are invited to present their experiments. An overview of IOV/IOD-services offered by Kayser-Threde and a programmatic outlook will complete the program. The idea behind the TET Customer Days 2013 is to provide a platform for exchange and discussion between agencies, industry and institutions.

Deutsche Kleinsatellitenmission TET-1 nimmt Regelbetrieb auf
Die Phase der orbitalen Inbetriebnahme des Ende Juli gestarteten Kleinsatelliten TET-1 wurde erfolgreich abgeschlossen. Dies bestätigte das fünfköpfige Review-Board, das daraufhin die Freigabe für den Regelbetrieb des nationalen Satelliten erteilte.

German small satellite mission TET-1 now commencing routine operation
The TET-1 satellite launched this July has successfully completed its orbital commissioning phase. This was confirmed by the five members of the review-board who then gave the green light for the German satellite to commence routine operation.
With the Technology Experiment Carrier TET-1 products which have accomplished on-ground tests will now have the opportunity to undergo further tests under the harsh conditions prevailing in space. TET-1 is the core element of the OOV (On-Orbit Verification) Programme of the German Space Agency (DLR) from which Kayser-Threde was awarded a contract as prime and systems leader for the realization of TET-1. Munich-based Kayser-Threde, a member of the prime standard listed OHB AG, also was in charge of the satellite launch and continues to support the mission beyond this phase.
In the commissioning phase the satellite bus was set into operation in space for the first time and all the required functional tests were performed. Only then were the eleven technology experiments on board activated: first one by one, then according to pre-defined payload scenarios. The generated data gave experimenters a preliminary insight into how their payloads are performing in space.
During routine operations the payloads will be activated on a regular basis over the next 12 months in order to evaluate their performance in a space environment. Kayser-Threde developed a power supply system specifically adapted to the demands of each of the individual payloads. Technology experiments on board include new-generation solar cells, a navigation receiver, a pico propulsion system for satellites, computer hardware, a sensor-bus system developed by Kayser-Threde for temperature measurement, a battery system, as well as an IR-camera for the detection of forest fires.
Outlook: Kayser-Threde and its project partner Astro- und Feinwerktechnik Adlershof GmbH were selected by DLR for a study for a successor mission (TET-2). The concept of a `TET Family` is to be able to offer institutional and commercial customers a satellite best suited for their desired applications: for classical OOV-applications, Earth observation as well as for the early detection of forest fires.
TET-1 project partners of Kayser-Threde are Astro- und Feinwerktechnik Adlershof GmbH, DLR`s German Space Operation Center (GSOC) located at Oberpfaffenhofen near Munich, and Lavoshkin Association. TET-1 was realized with funds from BMWi (grant no. 50 RV 0801). |

December, 2011
TET-1 is ready for launch and has been so for a couple of months now.
However, TET-1 is grounded here in our integration hall as launch will not be before next March. Our TET-1 team is tending to the satellite since TET-1's batteries have to be monitored and regularly charged and its overall condition checked.
We would like to wish both our readers and TET-1 all the very best for the coming year!

August 25, 2010:
The satellite will leave Kayser-Threde's integration hall tomorrow morning and will be moved to IABG's test facilities in Ottobrunn
near Munich. Air-suspension will provide for smooth and secure transportation.
Once there and short function tests completed, the environmental
test campaign is soon to start: electromagnetic compatibility tests
are scheduled for Monday, August 30 and will generate data on radiated emission and radiated susceptibility.
TET-1 will then be re-located and undergo another round of function tests prior to the series of mechanical tests and thermal tests.
The whole test campaign at IABG will last until September 27, 2010.
TET-1 will then return to Kayser-Threde. |

The "Test Readiness Review" was completed successfully.
Kayser-Threde's TET-1 team was soon focussing on another test:
A 24 hour mission operations test i.e. the simulation of a 1-day mission operation. It included the standard experiment scenario,
5 payload data downliks and 15 orbit simulations. Data downlink
and evaluation were effected at Kayser-Threde facilities by means
of the central check-out system.
Project manager Föckersperger on this week: "A truely busy week with lots of progress made. I really appreciate the outstanding job my team is performing. The schedule is tight and has been so for a while, but everyone is highly motivated."
Final Inspections of the TET-1 satellite and its systems are forseen for next week. |

Ready
for the environmental test program
Astro Feinwerktechnik and Kayser-Threde have started the final
integration of the
TET-1 satellite STM (Structural Thermal
Model) in Berlin mid November.
Following
the installation of the payload assembly on the satellite
bus a fit check with the MLI (Multi Layer Insulation) and
the solar panels has been performed.
The STM
is now ready for the environmental test program (vibration,
shock and thermal vacuum) at the DLR premises in Berlin Adlershof.

Kayser-Threde
receives Satellite Mission TET-1 Contract for
On-Orbit Verification from DLR
Munich. Kayser-Threde
GmbH received today the prime contract for the space and
ground segment as well as launch services for the satellite
mission TET-1 from the Space Agency of the German Aerospace
Center (DLR). The project volume of the Phase C/D amounts
to 21 million Euro.
The
contract entrusts Kayser-Threde and its subcontractors
with all aspects involved in the construction and manufacture
of the satellite, the various tests for space flight qualification,
the necessary infrastructure for the satellite mission
and all preparations required for launch. The TET-1 mission
is carried out under contract to DLR with funds from
the German Ministry for Economics and Technology (Bundesministerium
für Wirtschaft und Technologie) under reference number
50 RV 0801.
TET-1 is the core element of DLR’s On-Orbit
Verification Program(OOV). The main aim of
this program is to test new space technologies in a
space environment over a period of one year. Eleven
experiments will be accommodated by Kayser-Threde on
board the satellite which has a mass of 120 kg. TET-1
is scheduled for launch mid 2010 on a SOYUZ/ FREGAT
rocket as a secondary payload. The satellite will be
released in a sun synchronous orbit at an altitude
of approximately 500 km. |
