Dear visitor,

Welcome at ESF GmbH.

What you can find here:

  • Details on the company are given in tab ESF GmbH.

ESF GmbH is committed to truth. This is especially important in times when truth untruly tends to be considered as a "private opinion". Truth has one solid basis in the natural sciences. It has an other equally important solid basis in the revealed religion and in related philosophy. Each basis will finally lead to the "same" and only truth. Thus please do not expect that ESF GmbH, acting as a consultant, will accept to claim untruth or misapprehension, just because a customer would like to have it. As humans never are perfect, we also stick to the rule, to correct errors we made.

Cooperative Intelligen Transport Systems

Cooperative Intelligent Transport Systems (C-ITS) are being developed at various SDOs in a joint approach in order to merge the various "silo ITS applications" under one common cooperative platform which was originally developed at ISO TC204 WG16 ("the CALM group"). The CALM group introduced the concecpt of a "Bounded Secured Managed Domain" in ISO 21217, which is now being used for C-ITS.

Cooperative ITS can be defined as follows:

Dedicated Short Range Communications (DSRC)Europa

DSRC was a standardization project at CEN TC278 WG9:

  • EN 12253 DSRC Physical Layer
  • EN 12795 DSRC Data Link Layer
  • EN 12834 DSRC Application Layer
  • EN 13372 DSRC Profiles

ETSI provided standards for conformance testing:

  • EN 300 674 Part 1: General characteristics and test methods for Road Side Units (RSU) and On-Board Units (OBU)
  • EN 300 674 Part 2: Harmonized EN under 3.2 of the R&TTE Directive; Sub-part 1: Requirements for the RSU
  • EN 300 674 Part 2: Harmonized EN under 3.2 of the R&TTE Directive; Sub-part 2: Requirements for the OBU

Thiese harmonized standards are registered in the official list of harmonized standards of the European Commission.

  • TS 102 486: Intelligent Transport Systems(ITS); Road Transport and Traffic Telematics (RTTT); Test specifications for Dedicated Short Range Communication (DSRC) transmission equipment;
    Part 1: DSRC data link layer: medium access and logical link control;
        Sub-Part 1:
    Protocol Implementation Conformance Statement (PICS) proforma specification
        Sub-Part 2: Test Suite Structure and Test Purposes (TSS&TP)
        Sub-Part 3: Abstract Test Suite (ATS) and partial PIXIT proforma
    Part 2: DSRC application layer;
        Sub-Part 1: Protocol Implementation Conformance Statement (PICS) proforma specification
        Sub-Part 2: Test Suite Structure and Test Purposes (TSS&TP)
        Sub-Part 3: Abstract Test Suite (ATS) and partial PIXIT proforma

ESF GmbH was involved in the development of all parts of these DSRC base / profile / test standards, partly as member of a CEN project team or as member of an ETSI STF (Specialist Task Force).

Electronic Fee Collection (EFC)

ESF GmbH was and still is involved in several real EFC implementations in Europe.

The Europe Commission together with CEN TC278 WG1 developed a harmonized European Electronic Toll Service (EETS) considering

  • the well established CEN DSRC technology
  • GNSS/CN as currently being in use in Germany
  • the Italian Telepass technology, which is similar to CEN DSRC.

Such a harmonized service beneficially can be implemented as a C-ITS service on ITS in-vehicle platforms and ITS roadside platforms. This allows to reduce significantly the price of equipment related to EFC, and at the same time providing added-value services in the car.

General Purpose Interface Bus

This was a hardware and software development project of ESF GmbH in cooperation with IEB GmbH.

The universal interface GPIB-A1 together with a dual stepper drive module is in successful operation at NARDA Safety Test Solutions GmbH in several RF measurement set-ups including anechoic chambers with very high field strength. The stepper drives control position and movement of antennas.

Stepper drive

This is a useful device for physical layer measurements of any radio equipment. The basic interface provides digital I/O lines at TTL levels. Please check the manual.

Control of the GPIB instruments is done via the Agilent VEE software. ESF GmbH is a registered VEE developer using VEE 7.

Please contact info (at) for further details.
