• Effective radiated power
• Effective transmitting antenna height
• Nature of the path

20
Coordination distances (2)
ST61COORD

• Power ltgt values given
• linear interpolation shall be used
• Heights ltgt values given
• next higher height shall be used
• Percentage of sea path ltgt values given
• Next higher percentage shall be used
• Effective height gt 1200 m or no limiting
  distances given
• Procedure of shared bands applies.

21
Coordination distance tables
ST61COORD

ST61COORD 1.0
ST61COORD

• Input T02/TP2 electronic notices
• Output
• Report of coordination requirements
• Corrected notification file by removing from the
  original file the notices that should not be
  notified because the necessary coordination has
  not been carried out.
• The version ST61COORD 1.0 does not validate the
  data items.
