Galileo epfd calculations for
Eleventh Resolution 609 (Rev. WRC-07) Consultation Meeting
This contribution presents the results of epfd calculations performed by Galileo in preparation to the
Eleventh Resolution 609 Consultation Meeting (Shenzhen, 13-15 October 2014).
The document includes two sections :
- Section I is the Galileo calculation of the aggregate epfd, according to item 11.d) of the
Resolution 609 Terms of Reference, based on input data provided by each
operator/administration regarding the epfd of its own system,
- Section II is a comparison, for systems having provided new or updated data, of the single
system epfd obtained by the corresponding operator/administration and by Galileo.
Main conclusions are the following:
- Several systems have updated their data compared to previous Consultation Meeting, namely
COMPASS, GLONASS, and Inmarsat. In addition, two GSO networks (ALCOMSAT-24.8W
and RAGGIANA-18) have provided new data.
- The maximum aggregate epfd level assessed by Galileo, based on the single system epfd
matrices provided by each administration for its own system, remains below the Resolution
609 limit of –121.5 dB(W/m2·MHz):
o The maximum aggregate epfd in the band 1164-1215 MHz is –122.00
dB(W/m2·MHz), i.e. 0.50 dB below the Resolution 609 limit, when considering all
systems and networks. The maximum is reached at the 1176 MHz frequency. This
calculation takes into account both COMPASS regional and COMPASS global
systems.
o With the removal of NIGCOMSAT-1G/-1R, the maximum aggregate epfd in the band
1164-1215 MHz is –122.01 dB(W/m2·MHz), i.e. 0.51 dB below the Resolution 609
limit.
o With the removal of NIGCOMSAT-1G/-1R and of COMPASS Regional system
(which will eventually be replaced by the global system), the maximum aggregate
epfd in the band 1164-1215 MHz remains at ––122.01 dB(W/m2·MHz), i.e. 0.51 dB
below the Resolution 609 limit of –121.5 dB(W/m2·MHz). This is because the
maximum level of the COMPASS Regional signal is at 1207 MHz.
- For all systems and networks with new or updated characteristics, the single system epfd
matrices have been calculated using the Galileo tool. Comparison with the results obtained by
corresponding administrations shows an acceptable matching (maximum 0.1 dB difference).

Table 1 - RNSS systems considered at the 11th Consultation Meeting
The calculation of the maximum aggregate epfd was performed:
- Taking into account all systems and networks listed in Table 1.
- Removing NIGCOMSAT-1G/-1R network, which has neither confirmed nor updated its data.
- Removing NIGCOMSAT-1G/-1R network as well as COMPASS Regional system, since
COMPASS Regional system will progressively be replaced by COMPASS Global system,
and since taking both systems into account simultaneously is a worst case assumption.
I-2 Results of the aggregate epfd calculations
Taking into account, for each system listed in Table 1, the 1° epfd matrix as well as the Spectral
Adjustment Factor provided by the corresponding operator or administration, Galileo has carried out
three sets of calculation for the aggregate epfd.
Set #1 : 40 systems and networks (all those listed in Table 1)
Results are given in Table 2 and in Figure 1. The maximum aggregate epfd in the band 1164-1215
MHz is –122.00 dB(W/m2·MHz), i.e. 0.50 dB below the Resolution 609 limit of –121.5
dB(W/m2·MHz).

Table 3 - Aggregate epfd results for Set #2
Set #3 : 30 systems and networks (all those listed in Table 1 but NIGCOMSAT-1G/-1R and
COMPASS Regional system)
Results are given in Table 4 and Figure 2. The maximum aggregate epfd in the band 1164-1215 MHz
is still -122.01 dB(W/m2·MHz), i.e. 0.51 dB below the Resolution 609 limit of –121.5
dB(W/m2·MHz). The maximum level of the COMPASS Regional signal is at 1207 MHz, hence
removing this system only modifies the maximum aggregate epfd for the upper part of the 1164-1215
MHz band, as can be seen in Figure 2.

II Comparison of the single system epfd results obtained through different software tools
As indicated in Table 1, updated or new data for several systems and networks have been provided to
the Forum as input for the Eleventh Consultation Meeting. This section provides a comparison
between the single system epfd matrices calculated with the Galileo tool and those provided by
corresponding administrations .
II-1 Comparison of single system epfd for GSO networks
For all GSO networks corresponding to updated or new characteristics, the single system epfd matrix
has been calculated through the Galileo software tool, and compared with the result provided by
corresponding administrations. Table 4 below provides the maximum difference in this cell by cell
comparison, and shows an acceptable matching.
The comparison was not performed for Inmarsat-GSO-2N at 64E, since the epfd provided for this
networks is identical to the one which was already taking into account during the fifth and the Sixth
Consultation Meetings.
