About This Item

 

Full Description

ETSI EN 301 926 applies to Telemetry, Command and Ranging (TCR) systems operating typically in the following bands:
  • 5 850 MHz; 6 725 MHz uplink; 3 400 MHz; 4 200 MHz downlink;
  • 12 750 MHz; 14 800 MHz and 17 300 MHz; 18 100 MHz uplink; 10 700 MHz; 12 750 MHz downlink;
for Geostationary Communications Satellites.

The present document sets out the minimum performance requirements and technical characteristics of the ground/satellite Radio Frequency (RF) interface partially based on Spread Spectrum Multiple Access (SSMA).

With the growing number of satellites, the co-location constraints and the maximization of bandwidth for Communications Missions, and interference has motivated the elaboration of the present document for geostationary satellites based on Spread Spectrum techniques.

The present document addresses the following applications:
  • Telemetry;
  • Command (Telecommand);
  • Ranging.
Currently, no RF and Modulation standard exists for the TCR of geostationary communication satellites. The aim of the present document is to respond to such requirements. There are consequently similarities with existing agency standards, such as those listed in annex I, although some specifics have been introduced to respond to the requirement of multiple access for collocated geostationary communication satellites.
