Parts Agency


The Motive


Why a EEE Parts Agency?

Spacecraft have to withstand a harsh environment such as vibration and mechanical shock during launch, exposure to radiation in orbit, a much wider temperature range than in terrestrial applications, the environment on other planets and more.

Despite these extreme environmental conditions the equipment has to function without failure for many years (e.g. 15 years or more for telecommunication satellites), so maximum attention must be given to reliability.

For electronic equipment the key factor to meet these requirements are the EEE parts used. Thus the selection and testing of EEE part must be optimized to fit to the mission demands to be successful.

There are various drivers in the process of sourcing EEE parts for space use:
01
Identifying the correct EEE parts: needed quality level, manufacturer, type and the necessary testing and quality assurance measures.
02
Logistic complexity: many different part types have to be procured from numerous parts manufacturers at the same time. Additional testing and quality assurance measures have to be organized for a large selection of items in parallel and on time, often involving third parties such as specialized test houses.
03
Schedule: The delivery times of EEE parts have a major influence on the equipment schedule. Knowledge of critical schedule drivers and processes to avoid or minimize their risk are mandatory.
04
Supplier market: For HiRel EEE parts there are many monopolistic suppliers or suppliers who require close control of quality and schedule.
05
Counterfeit Parts: A threat that affects more and more the space industry and requires a sophisticated approach and continuous improvement in methods to stay ahead.
06
End customer demand on specific documentation or need for justification for the use of specific parts requiring statements and support by experts.
07
Compliance to export control regulations.
All these facets are handled most efficiently by a dedicated organisation, a Parts Agency. The Parts Agency at Tesat has all the know-how, expertise, manpower and tools to successfully fulfill any EEE parts demand for space use.

The Facts

More than 40 years of Experience

Tesat-Spacecom as a major producer of space equipment is one of the largest users of high reliability EEE parts in Europe. Today at Tesat’s Parts Agency over 85 experts are deeply involved in all aspects of supply and use of EEE parts in space.

We assist the external customers and the equipment business lines at Tesat regarding the EEE parts selection process, conduct all purchasing as well as quality assurance activities. Finally we also solve any parts related problem that may arise on parts level as well as during equipment production, test and flight operation.

Started in 1972, up to now many thousands of different part types have been procured and thus have established Tesat as Europe‘s largest and most experienced procurer of EEE parts for space.

More than 70 customers worldwide have entrusted Tesat-Spacecom to procure their EEE parts. Besides these we have also been acting as Centralised or Coordinated Parts Procurement Agency (CPPA) for numerous major European programmes.

The Services

Procurement & Engineering Services for EEE Parts

Technical and Engineering Services

Parts to be used for space applications are carefully selected according to their materials, their radiation sensitivity, and the component technologies. Here extensive know-how gained in support of Tesat´s equipment business is an asset.

Our in-depth knowledge of the supplier market as well as long experience with most major end customers enables us to recommend EEE parts to you – most appropriate for your specific project requirements.

Well known part types which are listed in Preferred Parts Lists (PPLs) are used extensively. If new part types are required, evaluation programs are performed to investigate the sustainability of those parts for space applications. Whenever necessary, specifications (resp. source control drawings) are issued by Tesat with a format similar to the ESCC or MIL system.

Our technical experts will issue all documents needed for additional testing (e.g. RVT, Upscreening) and will perform or control the testing to the full satisfaction of the customer.

Key components that are not available as qualified parts or only from single sources are a major problem for the space industry. We are continuously cooperating with the manufacturers to promote qualification of new part types and support their market introduction.

Quality Assurance

The requirements for a quality management system are particularly high in the space industry. The failure of components or deficient components can have far-reaching and even devastating consequences. Therefore, an effective quality management system is essential for a Parts Agency. The main objective of the quality management system is to minimize risks and provide a reliable framework for organizing the procurement of the components.

The quality and reliability of EEE parts for space is assured by extensive evaluation and qualification of parts before they are used for space applications. For flight parts, the manufacturing processes and the measurement and inspection procedures are tightly controlled. In addition, detailed inspection and analysis of batches of parts is carried out at the manufacturer’s sites as well as independently at Tesat. Also the documentation supplied by the manufacturer is thoroughly reviewed. Approved parts are shipped to the users with Certificates of Conformance (CoC´s). Parts problems are dealt with using the non-conformance procedures according to ESCC requirements.

A constantly increasing risk is counterfeit parts. Avoiding such parts and detecting them as early as possible in the supply chain requires more and more meticulous approaches. As a technically highly competent and independent expert this issue is addressed by us with maximum attention and a clear strategy of quality assurance measures such as dedicated test, data reviews, plausibility checks etc. Our state-of-the-art parts laboratory that is fully equipped with the necessary tools greatly facilitates the technical analysis and post-pro-curement inspections required for quality assurance.

Project Management

An experienced project manager is assigned to each customer. The project managers are dedicated to provide all necessary support from purchase order placement to post-delivery support. Giving the customer one qualified point of contact for all his questions, the project managers are focused on providing complete and satisfying solutions for the customers.

Reporting Tools allow the customer to monitor the whole procurement process through a realtime Internet reporting system. This tracking system shows the detailed delivery status of the components, technical information about the components, PAD and release status and additional testing activities. Tesat-Spacecom has also extensive stocks of Hi-Rel components that can be of great use in procurement projects. Tesat-Spacecom EEE stock parts can be accessed through the Tesat website or directly via: stock.eeeparts.tesat.de

Purchasing

The purchasing of the parts must be carried out in a manner that ensures the lowest cost and shortest delivery time within the necessary timeframe. The basis for ordering of the parts are the requirements determined in the Parts Approval Document (PAD), the quantities needed and the need date of the customer.

On that basis, Tesat-Spacecom negotiates with the supplier, orders the parts, and monitors the manufacturing. High order volumes, frame contracts and a long-term relationship with all major manufacturers ensure the reliable and prompt availability of the parts needed under excellent commercial conditions. We take care of all activities necessary to meet export control regulations affecting the parts. Issuing correct and complete documents in time is crucial for a timely release of the parts.
