- 18. DEMONSTRATION OF EARTHSTATION COORDINATION AND REGISTRATION – Definition of coordination area 18 The coordination area represents the area surrounding an earth station sharing the same frequency band with terrestrial stations , or the area surrounding a transmitting earth station that is sharing the same bidirectionally allocated frequency band with receiving earth stations , within which the permissible level of interference may be exceeded and hence coordination is required. Coordination area ≠ Interference affects the stations located inside the area

- 23. 23 DEMONSTRATION OF EARTHSTATION COORDINATION AND REGISTRATION – Predetermined coordination distances For mobile earth stations, the coordination area is determined by extending the periphery of the area, within which the mobile earth stations are operating (called the “service area”), by the coordination distance. In such cases, it is often preferable to use predetermined coordination distances contained in Table 10 of Appendix 7.
