Tasks of WTD 81

WTD 81 performs experiments and analyses as well as integrated compliance demonstrations in the framework of the procurement and in-service support process called Customer Product Management (CPMCustomer Product Management). Apart from this it coordinates research & technology (R&TResearch and Technology) projects defined by the Federal Ministry of Defense R&TResearch and Technology program. WTD 81 also provides technical support for defense projects and manages projects under the CPMCustomer Product Management.

When fulfilling its core tasks concerning systems and equipment, research & technology and technical support for the Bundeswehr, WTD 81’s competencies are mainly focused on the following fields:

In the area of reconnaissance technology, WTD 81 carries out studies on air and space-based imagery intelligence (IMINTimagery intelligence) focusing on “concepts and procedures”. The topic of research is the processing of information obtained from reconnaissance sensors in the optical and infrared ranges as well as radar.

Electronic warfare (EWElectronic warfare) is of particular military importance. It comprises all measures related to the reconnaissance of enemy electromagnetic emissions and/or methods of disabling them with countermeasures. WTD 81 is involved in all stages of the development, in-service use and procurement of EWElectronic warfare systems.

Among other systems, the technical center studies radar and laser warning systems, signals intelligence systems and radio frequency counter-IEDImprovised explosive device systems (RF-C-IEDCounter Improvised Explosive Device). WTD 81 also evaluates measures to minimize the emissions of own systems to prevent jamming and reconnaissance of these systems.

In order to be able to fulfill its tasks, WTD 81 has one of the largest shielded anechoic halls in Europe for the study of electromagnetic compatibility and electromagnetic effects. The EMCelectromagnetic compatibility Test Center of WTD 81 is the central Bundeswehr point of contact in all matters of electromagnetic compatibility and electromagnetic effects.

WTD 81 conducts a variety of experiments, tests, demonstrations and studies in order to create and optimize the network enabled operations capabilities of the Bundeswehr and in order to analyze and evaluate chains of effects.

ZINS makes a major contribution to this effort by providing knowledgeable experts and the infrastructure and the required technical equipment for all phases and aspects of the respective measures, as well as documentation and presentations.

The main tasks of the Command and Control Information Systems unit are providing development support to industry projects and testing the compatibility of national and international command and control information systems / command and weapons control systems with each other and the army communication system.

Support for the command and control process by transmitting the current reports, orders and situation pictures is provided at all command echelons and for all branches via LAN, WAN or radio. Interoperability tests serve to guarantee an effective command and control capability for multinational units in operations ranging from peace-keeping measures to warfare. Bundeswehr Technical Center 81 is the meeting venue for all nations participating in the Multilateral Interoperability Program (MIPMultilateral Interoperability Program).

The IT security branch (Bundeswehr IT security test center) at WTD 81 tests and evaluates IT products and develops release and certification recommendations for the operation of classified hardware and software. WTD 81 also operates an approved evaluation facility of the Bundesamt für Sicherheit in der Informationstechnik (Federal Office for Information Security) in this branch and evaluates IT products that are subject to certification.

WTD 81 also supports BAAINBw in the selection and development of IT products for their projects.

The IT security branch of WTD 81 has the following tasks:

  • Evaluation of IT security products subject to certification IAW Common Criteria
  • Investigation of technical weak points
  • Advice and support for projects
  • Market surveys, testing and evaluation of IT products.
  • Research and technology in the areas of networks, software and hardware vulnerabilities, penetration tests, app verification
  • Work in international bodies

Military command and control processes and administrative applications require a secure transmission of voice and data between the Bundeswehr communication systems in a national or international environment. This requires coupling different tactical and strategic networks including jamming-resistant radio systems. WTD 81 has to implement this process in a cost-effective way with modern, mostly commercially available technology. The tactical networks used by crisis reaction forces in remote areas of operation are linked via secure satellite links.

WTD 81 conducts technology studies in this field and supports the implementation of new technologies and interoperability demonstrations by testing and validation based on reference systems.

The organizational unit "Weapon System Technology, Fire Control Technology & Testing Technology" works on cross-branch defense technical tasks concerning large-scale military systems in the remit of WTD 81.

It carries out studies and demonstrations on weapon systems including fire control technology and integrated testing systems. Apart from that, this unit of the technical center coordinates relevant aspects of the branches EMCelectromagnetic compatibility, Navigation, Communication and Command and Control Information systems.

The navigation systems comprise GPSGlobal Positioning System satellite navigation receivers, purely inertial systems and hybrid systems that use both types of navigation. WTD 81 has a measurement vehicle for conducting measurements on the inertial systems in which the values obtained from test specimens can be compared directly with a laser gyro reference system while on the move. At WTD 81, satellite navigation systems are tested with a GPSGlobal Positioning System simulator which can emulate encrypted military P(Y)-code signals. Apart from satellite signals, the corresponding inertial signals are generated for the hybrid systems. Therefore the simulator is the only simulator of its kind in Germany.

WTD 81 also has the important task of providing technical advice, measurements and integrated verification in the field of radar and identification technology.

In the field of primary radar technology WTD 81 mainly works with ground-based radar systems and radar sensors on flying platforms. In the field of secondary radar technology (Identification Friend or Foe, IFFIdentification Friend or Foe) WTD 81 is in charge of all Bundeswehr interrogators and transponders and conducts on-site measurements with the IFFIdentification Friend or Foe reference station. 

The field of technology “radar sensors and signal processing” is also located here. This is where research and technology studies on topics such as “multi-functional radar systems”, “passive radar” and “millimeter wave technology” are conducted.

WTD 81 supports government institutions and industry in the evaluation of foreign defense materiel. For this purpose the technical center participates in national and international technical working groups, it commissions and supports studies and evaluates technologies and development trends in foreign defense materiel.

In the area of homing technology the technical center tests and evaluates seeker systems with different technologies (radar, infrared, laser, multisensor). Sensors (receivers) and signal processing (processors) are tested and simulations which integrate aerodynamics are conducted.

WTD 81 also tests foreign defense materiel from this range of applications and is active in the field of research and technology.

Facilities of WTD 81

WTD 81 fulfills its tasks by employing highly qualified personnel, modern technical equipment, making extensive use of network enabled simulation technology, future-oriented training and education and running its own workshops.

In the GNSSGlobal Navigation Satellite System simulator at WTD 81 a satellite navigation receiver is moved along a virtual testing track using simulated satellite signals. Navigational accuracy is derived from the deviation of the calculated position from the reference position.

Simulated test drives, unlike real test drives, can be reproduced very accurately. This is the only method that can be used to find out how different parameters such as dynamics or reception interferences due to masking and faults in the satellite system influence position accuracy.

One of the largest anechoic chambers in Europe is part of the test center for electromagnetic compatibility (EMCelectromagnetic compatibility Test Center) at WTD 81. The chamber is 41 x 16 x 14 meters large and has a 10 x 10 meters entrance gate as well as a turntable lift with a diameter of 9 meters and a lifting capacity of 60 tons. A second anechoic chamber (10 x 7 x 4 meters) is available for smaller test items. The EMCelectromagnetic compatibility Test Center at WTD 81 is also equipped with a laboratory for lightning protection and electromagnetic pulse (EMP) and an 11 x 8 x 6 meters mode stirring chamber (MSCmode stirring chamber).

The technical equipment of the EMCelectromagnetic compatibility Test Center at WTD 81 also comprises power amplifiers with a range of 500 W to 10 kW for maximum field strengths of 600 V/m continuous wave (CWcountinuous wave) and/or a pulse of 2500 V/m, mobile and stationary measuring sites for emission measurements in the range of 16 Hz to 40 GHz and interference immunity tests between 30 kHz and 40 GHz, electrostatic discharge test systems (ESDelectrostatic discharge) and surge current generators up to 100 kA in order to simulate the effects of lightning.

The WTD’s EMCelectromagnetic compatibility Test Center is the central point of contact of the Bundeswehr for electromagnetic compatibility (EMCelectromagnetic compatibility) and electromagnetic effects (EMEelectromagnetic effects), electrical safety and lightning protection. It conducts compliance demonstrations in the area of electromagnetic effects on components, equipment and complete systems in accordance with national and international standards (VG standards, STANAGStandardization Agreement, AECTPAllied Environmental Conditions Testing Publication, MIL-STD, etc.) and demonstrates the safety of ammunition via EMCelectromagnetic compatibility testing.

It also provides advice and support in national and international projects and conducts application-oriented studies in the field of EMEelectromagnetic effects. This involves the exploitation of sources of strong electromagnetic radiation (HPEMHigh Power Electromagnetics) for Counter-IEDImprovised explosive device measures (C-IEDCounter Improvised Explosive Device), counter-UAS or car stop.

The radar homing head simulator at WTD 81 uses a horn antenna to show a target that is to be engaged on a target wall. The target is measured by the homing head and the calculated error signal is transmitted to the autopilot’s simulation model in the computer in order to calculate the tracking movement of the motion simulator.

The radar homing head simulator at the technical center is equipped with a three-axis motion simulator, a radar target wall, an optional infrared target generator and a signal, environment and jamming generator. The horn antennae can be moved horizontally, vertically and around their roll axis.

Hardware-in-the-loop (HIL) simulations of optical and optoelectronic components and systems are conducted at the target simulation dome of WTD 81. The test objects are exposed to realistic scenarios and targets covering different spectral ranges from UVB to long-wave IR. Simulators with three or six degrees of freedom are available for motion simulation.

The target simulation dome at the technical center has an external diameter of about 46 meters, which makes it one of the largest modular cantilevered dome structures in the world. In its interior there is a projection cupola with a diameter of 40 meters. The unique surface of the projection cupola is not a Lambertian reflector but has a radiation pattern which mainly reflects projections to the center of the cupola.

The ZINS at WTD 81 conducts experiments in the fields of concept development & experimentation (CD&EConcept Development and Experimentation), network enabled operations and distributed simulation.

It has several laboratories and auditoriums, internal and external networking facilities and one auditorium with 70 workstations and a 7.8 x 2.6 meters media screen in order to flexibly visualize the experiments.
