BS EN 16603-50-02:2014

What is BS EN 16603-50-02 - Ranging and Doppler tracking about?

BS EN 16603-50-02 discusses space engineering. BS EN 16603-50-02  applies to spacecraft that are supported for ranging or Doppler tracking by direct links to Earth stations and to all related Earth stations (therefore, BS EN 16603-50-02 is not applicable for spacecraft supported by data relay satellites) operating within the Space Operation, Space Research and Earth Exploration Satellite services (therefore, BS EN 16603-50-02 is not applicable to the Meteorological Satellite service) as defined in ECSS-E-ST-50-05 clause 1.

Other space telecommunication services are not covered in this issue.

BS EN 16603-50-02 applies to projects with unprocessed ranging accuracies of 2,5ns to 30 ns (for conventional projects with tracking accuracies less stringent than these, CCSDS 401.0-B recommendations may be sufficient) and Doppler tracking accuracies of 0,1 mm/s to 1 mm/s. The analysis of compatibility between systems compliant with this standard and with the CCSDS recommendations.

Who is BS EN 16603-50-02 - Ranging and Doppler tracking for?

BS EN 16603-50-02 on ranging and doppler tracking is applicable to:

• Spacecraft transponder and Earth station equipment manufacturers
• Aerospace and defence industries
• Space engineers
• Design engineers
• Quality compliance personnel of space product

Why should you use BS EN 16603-50-02 - Ranging and Doppler tracking?

The ranging and Doppler tracking system is a spacecraft tracking system capable of providing information on the range and range rate between a spacecraft and an Earth station.

BS EN 16603-50-02 defines the requirements concerning spacecraft transponder and Earth station equipment for the purposes of ranging and Doppler tracking. BS EN 16603-50-02 provides criteria by which the extent to which the accuracy of the measurements is influenced by equipment effects can be determined.

The purpose of BS EN 16603-50-02 is to:

• Ensure compatibility between space agencies' spacecraft transponders and the ranging and Doppler tracking facilities of the Earth stations for the Space Operation, Space Research and Earth Exploration Satellite services
• Ensure, as far as possible, compatibility between space agencies' spacecraft transponders and other networks from which they request support
• Ensure an adequate level of ranging and Doppler tracking accuracy for missions conforming to this standard.

BS EN 16603-50-02 facilitate the early design of flight hardware and ensure that the resulting interfaces and system performances are compatible with given ranging and Doppler tracking configurations and specifications.
