Idealized geometric estimate for a geostationary position on a spherical Earth. It is not live coverage, polarization/skew, an obstruction check, or pointing authorization. Verify the spacecraft position, datum, operator instructions, and site survey.

Navigate architecture guides by functional boundary, interface, and responsibility.
Frequency Labels Are Not Assignments
C-, Ku-, and Ka-band are broad engineering labels. They do not by themselves establish an allocation, licence, channel, direction, or usable service.
Band-label boundaries
| Band | What the label does not establish |
|---|---|
| C-band | A broad label spanning multiple services and regional allocations; it does not define one universal uplink/downlink pair. |
| Ku-band | Multiple fixed- and broadcasting-satellite allocations use this label; it does not identify a legal channel or direction. |
| Ka-band | This label covers multiple higher-frequency allocations; terminal, feeder-link, gateway, and service assignments must be distinguished. |
Use the applicable ITU Region, national frequency table, licence, operator access plan, and equipment documentation for exact frequencies.
Verify before design or transmission
A deployable frequency plan needs evidence at each regulatory and system boundary.
- ITU Region, radio service, and national allocation
- Uplink/downlink direction, assigned channel, bandwidth, and polarization
- Licence, coordination conditions, and emission limits
- Operator access plan and certified equipment range
- Site interference environment, pointing, and acceptance measurements
