This Recommendation provides a model for use in the initial evaluation of the potential for radio sources other than in the radionavigation-satellite service to cause continuous interference to a radionavigation-satellite system or network operating in the 1 164-1 215 MHz, 1 215-1 300 MHz, 1 559-1 610 MHz and 5 010-5 030 MHz bands.

This Recommendation is intended to provide guidance on ITU-R Recommendations related to the technicalcharacteristics and protection criteria of radionavigation-satellite service (RNSS) receiving earth stations andcharacteristics of RNSS transmitting space stations planned or operating in the frequency bands1 164-1 215 MHz, 1 215-1 300 MHz, 1 559-1 610 MHz, 5 000-5 010 MHz and 5 010-5 030 MHz.In addition, this Recommendation gives a brief overview of those Recommendations.
The characteristics and protection criteria for radionavigation-satellite service (RNSS) spaceborne receivers are presented in this Recommendation. This information is intended for performing analyses of radio-frequency interference impact on RNSS receivers operating space-to-space in the bands 1164-1215 MHz, 1215-1300 MHz and 1559-1610 MHz from emissions of non-RNSS sources.
This Recommendation provides a method for use in the initial evaluation of the potential for relevant 1 radio sources other than in the radionavigation-satellite service (RNSS) to cause pulsed interference 2 to a radionavigation-satellite system or network operating in the 1 164-1 215 MHz, 1 215-1 300 MHz, and 1 559-1 610 MHz frequency bands. The evaluation method components are a set of equations and a table of recommended parameters and allowable degradation ratios 3 for each frequency band and RNSS receiver type. Although the evaluation method equations are applicable to RNSS receivers in the 1 559-1 610 MHz band, further studies would be needed to determine the necessary table of recommended method parameters and allowable degradation ratios for that frequency band before the evaluation method is completely defined for the 1 559-1 610 MHz band.
This European Standard (EN) has been developed by the European Standardization Organization ETSI (European Telecommunication Standardization Institute) and specifies requirements in the telecommunications sector.
