RAPS-II
Officially EUROCONTROL Qualified ASTERIX Reference Product & Test Tool

Recording, Analysis, Playback & Simulation System for Surveillance Data
RAPS-II is a powerful and versatile toolset for the testing, analysis and validation of surveillance data. It is the world's first officially qualified Reference Product for the emerging ASTERIX standard.

RAPS-II allows the multi-channel recording and playback of a wide range of radar formats and protocols. It provides highly sophisticated and flexible functions for filtering, format-sensitive analysis, visualization and test data generation. Ease-of-use
is enhanced by means of a fully graphical user interface.

RAPS-II caters for a wide range of application areas including monitoring, quality analysis and trouble shooting in control centers or at radar sites. RAPS-II has also proven many times that it is an indispensable tool for integration testing and acceptance testing of surveillance products.

Recently RAPS-II successfully underwent a EUROCONTROL qualification process for recognition as an ASTERIX Test Tool and Reference Product.

ASTERIX Reference Product & Test Tool
 

The ASTERIX radar data format (All-Purpose Structured EUROCONTROL Radar Information Exchange), in the past years continuously refined and extended, is currently on the verge of being adopted as a world-wide surveillance data standard. In 1989, COMSOFT, on behalf of EUROCONTROL was the first company to implement ASTERIX. Today COMSOFT is again breaking new ground with the world-wide first qualified ASTERIX reference and test tool.

Asterix Certification
The RAPS-II analysis functions allow an independent party to certify an ASTERIX implementation against the official standard. For this purpose the RAPS-II generates, e.g. reports identifying format and protocol violations, as well as corresponding statistics over a data stream.

RAPS-II’s powerful set of tools for ASTERIX analysis, processing, visualization and data simulation, are each especially aligned to the new format.

The tools provide a comprehensive workbench for all tasks related to the practical use of ASTERIX during testing, acceptance or maintenance of any state-of-the-art surveillance product.

Support for all Existing Asterix Categories
RAPS-II fully supports all currently standardized ASTERIX radar data categories. Further, for all categories on the way to standardization, RAPS-II provides support based on the latest official working drafts. COMSOFT is closely monitoring the standardization process, and provides upgrades to newer versions of the ASTERIX standard as soon as they are available. Supported ASTERIX categories include: 0, 1, 2, 3, 4, 8, 9, 10, 11, 16, 17, 18, 21, 30, 31, 32, 34, 48, 62, 63, 65, 252, 253 and various dialects.

Support for new Categories & UAPs
RAPS-II allows a sufficiently authorized user to define new ASTERIX categories as well as User Application Profiles (UAPs) according to the specific requirements of an application. The definition is provided as an ASCII descriptor file and is automatically transformed for runtime execution. This provides the user with full flexibility for ASTERIX adaptations and test beds.

Long Years of Asterix Experience
COMSOFT has continuously refined and upgraded RAPS-II since the first ASTERIX implementation in 1989, when the early ancestor of this product, was developed. Being as close to the official standard as possible, it has during the past 10 years helped aviation authorities and industry partners to align and test their ASTERIX implementations. With its recognition as official ASTERIX Reference Product, RAPS-II will in the future further contribute to a smooth interoperability between surveillance systems.

Eurocontrol Qualification
  RAPS-II is Official Asterix Reference Product & Test Tool
COMSOFT’s RAPS-II is the first product on the market that underwent a EUROCONTROL qualification process to assess its eligibility as ASTERIX Test Tool and Reference Product. The qualification took place initially in 1998 and was renewed in 2003 for all new ASTERIX formats.

The qualification process involved extensive testing of the equipment by independent accredited test laboratories, quality auditing and submission of comprehensive qualification evidence to a jury. The jury was composed of EUROCONTROL officials, member state representatives and representatives of the ASTERIX standardization committee as well as industry delegates.

The official jury passed RAPS-II, attesting that the product satisfies the EUROCONTROL technical and non-technical requirements for an ASTERIX Test Tool and Reference Product.

As part of this, RAPS-II demonstrated its eligibility to be used for evaluation and certification of arbitrary ASTERIX implementations against the standard.
