4 RADAR SPARE PARTS The steep GmbH produces spare parts for original components of the radar system RRP- 117 (Remote Radar Post). These have the same form, fit and function as the parts of the original equipment manufacturer, but have a better performance and a lower price. Our portfolio also includes re-designs of obsolete and no longer available original components. The spare parts have proven successful in deployment for many years. As a rule, they can also be used in the system FPS-117. Our spare parts portfolio currently includes L-Band Amplifiers in the versions 2 x 5 W, 50 W and 100 W, T/R Switches, Phase Shifters, Combiner/Divider (1-fold, 6-fold and 10-fold) as well as DC-Distribution (1-fold, 6-fold and 10-fold). L-Band Amplifier (in this figure: 2 x 5 W) T/R Switch Phase Shifter Combiner/Divider (in this figure: 6-fold) DC-Distribution (in this figure: 10-fold) Test Sockets for L-Band Amplifiers In addition to our spare parts, we offer test sockets for L-Band Amplifiers. These enable a functional test and the measurement of the high-frequency (HF) power of individual amplifiers under operating conditions. This method allows a significant saving of time in troubleshooting. page 04

5 TECHNICAL DOCUMENTATION In addition to the services in radar systems support, our service also covers the technical documentation as well as a logistics and obsolescence management. This includes the maintenance of material databases in close cooperation with the customer. In addition, our department updates and maintains user manuals and service documentations as well as other relevant documents on the basis of information on technical changes from the workshops and data from radar sites. Our obsolescence management solves individual challenges in the procurement of obsolete spare parts through the procurement on global markets as well as by re-designs from steep and/or partners. Examples of our services in documentation: Technical documentation according to ASD S1000D TM Maintenance instructions Operation and user instructions Spare parts catalogues Circuit diagrams Manuals Training literature Document lifecycle management Obsolescence management TRAINING The aim of our service in the area of training is the ideal qualification and advanced education of our clients specialist staff for the preventive maintenance of radar systems. Training contents are for example the use of testing equipment and the targeted adjustment of the relevant processes. With the implementation of on-site training, we help to create a particularly close link to the customers radar system and to the immediate practical application of the acquired knowledge. In the development of training materials, our specialists from documentation and training closely cooperate and, by doing so, ensure the ideal combination of technical and educational subject-matter expertise. In this context, we benefit from the extensive experience of our training division in qualification of personnel at radar sites as well as in education for civilian and military customers. page 05

6 RADAR EVALUATION Air traffic is steadily increasing, thus imposing severe demands on the radar systems used for identification or direction of aircraft and plotting of the air traffic situation. For more than 25 years, steep has been providing checks of the radar systems of the German Air Force (PSR/SSR/Mode S) in regular intervals of two years. Regular checks are performed to ensure that the primary and secondary radar systems are up to the specified performance characteristics and are compliant with national and international requirements. The steep GmbH performs flight checks and system performance checks. With the help of a comprehensive final report, the customer can easily verify the fulfilment of all performance requirements. In addition to the services for the German Air Force, steep supports the commissioning of new surveillance or approach radar systems in various European countries, as well as the implementation of flight checks in the Middle East. Flight Checks Radar users, such as civilian aviation authorities, air navigation service providers or military air navigation authorities, need to carry out flight checks on radar systems in order to confirm that the system is within the required manufacturer-specific as well as international regulations and standards (ICAO, Eurocontrol). Radar flight checking typically comprises an analysis of the following parameters: Positional accuracy in range and azimuth for PSR and SSR, compared with GPS as a reference Probability of detection (Pd) of PSR and SSR in graphical or tabular representation Correlation rate of PSR and SSR Cone of silence evaluation Decoding rate (Mode A/C and Mode S) False plot analysis Calculation of the coverage of a sensor based on terrain data (screening) System Performance Checks (SPC) The system performance check verifies that the systems meet all specified performance demands and all operational requirements. For this purpose, antenna, transmitter, receiver and signal processing are checked regularly. In addition, necessary system alignments are performed. page 06

7 OBSOLESCENCE SOLUTIONS FOR RADAR SYSTEMS Project: Replacement of the Radar Data Processors (RDP) for RRP-117/FPS-117 For more than 40 years, the steep GmbH has been providing technical support services for the control and reporting centers of the German Air Force. In 2013, steep developed an obsolescence solution for the radar system RRP-117/FPS-117 of the German Air Force. The radar data processors (RDP) of the radar system, including the functionally linked data processing and system control components, were obsolete. Within the scope of an obsolescence solution, the obsolete hardware was replaced by suitable commercial off-the-shelf equipment. The previous hardware was a VAX 6000 computer. The used operating system was a VAX VMS 5.5 software by the company Digital. The RDP was responsible for the entire control of the radar system RRP-117/FPS-117, plot processing (target signals) and the correlation of target information from primary and secondary radar systems. The application software of the RRP-117/FPS-117 is written in FORTRAN 77 code. Instead of operating systems Digital VAX VMS 5.5 and Digital UNIX 4.0D, steep uses a Linux server operating system and thereby benefits from the stability and security of this diversely and comprehensively used operating system. The application software for the radar system RRP-117/FPS-117 consists of the mission software as well as the tools used for the creation, administration and documentation of the mission software. steep has ported this application software to the Linux operating system. Additional software modules were written in order that all calls to the application software can be run on the operating system without having to rewrite the source code of the application software. Furthermore, an ASTERIX interface was integrated, making it possible to transfer the radar plot data to the control and reporting center via a standardised radar data network. The operating workstation in the maintenance shelter of the RRP-117/FPS-117 was redesigned and integrated. The obsolescence product of the RDP computer by the steep GmbH has been in use for the radar systems RRP-117/FPS-117 of the German Air Force since the beginning of With this obsolescence solution, the remaining term of the radar system that has been in continuous use for approximately 20 years could be extended by more than a decade. page 07
