[7C 5A/] ANNEX 1 List of current and planned EESS (active) systems in the 5 GHz range (non-exhaustive) Note: This table has been derived to the best knowledge of the delegates attending the Space Frequency Coordination Group (SFCG) and WP 7C and should hence only be used as informative document since no guarantee can be offered that it fully covers all the existing and planned missions with sensors operating in the 5 GHz range.

Note 2: starting the week of 3 October 2016 Jason-2 will be moved to an 'interleaved' orbit, ~160° different from Jason-3, to split the ground track and separate them by about 1/2 of the repeat cycle (5 of the ~10 days). The inclination and altitude will be the same, but not the phase. Note 3: Satellites of the constellation use different orbital planes, are separated by 120°.
It can also be seen that the interference level corresponding to the protection criteria is exceeded for more than 20% of the time. The situation is also depicted on Figure 14 below showing in red the interfered portion of images (vs the non-interfered in white). 14 Interfered portion of images (in red) vs non-interfered (in (Over the UK – JTG options A1 and D1) It appears obvious that in these situations, the Sentinel-3 sensor will be totally ineffective over most land and coastal areas, in particular all urban and suburban areas. Finally, 13 provides the levels of interference in excess for the 3 RLAN density options (D1, D2-low and D2-High) and antenna Options A1 and A3. 13 Interference in excess (over the UK) Scenario Active RLAN density (Nb per inhabitant per 320 MHz) Nb of active RLAN over the UK (in 320 MHz) Interference in excess for antenna Option A1 Extrapolated for antenna Option A3 (A1 – 4 dB) JTG Option D1 0.0048 305 009 7.8 dB 3.8 dB JTG Option D2-low 0.00897 567 918 10.6 dB 6.6 dB JTG Option D2-high (D2-Low +10 dB) 0.0897 5 679 180 20.6 dB 16.6 dB 3.2.7 Dynamic analyses results over London metropolitan Figure 15 gives the cumulative distribution functions of interference corresponding to a deployment of 567 918 RLANs over the UK, including 115 737 RLANs over London metropolitan area (Option D2-low) and antenna Option A1. 15 Interference for Sentinel-3 (Over London Metro – options A1 and D2-low) It can be seen that the EESS (active) protection criterion is largely exceeded by 16.6 dB (–104.1 dBW). It can also be seen that the interference level corresponding to the protection criteria is exceeded for 100% of the time. Finally, Table 14 provides the levels of interference in excess for the 3 RLAN density options (D1, D2-low and D2-High) and antenna Options A1 and A3.
