This note will briefly discuss the possible frequency allocations we may use.
ITU Regions
Our applications mainly consider Region 1, however, for future applications related to Arctic sensor systems, Region 2 might be applicable. Therefore, we should consider these this too.
Allocations
The frequency licensing scheme that seem most relevant for us to use, are the bands allocated by Earth Exploration Satellite Services (EESS).
In UHF, the 400.15 to 403 has this + space operation (TT&C) as main allocation. In addition, there is a secondary allocation in the band 432 - 438. The main allocation here is for HAM (radio amateur) use.

Possible frequency allocations
The following is from the relevant sections of ITU Radio Regulations. The allocations are similar for the three regions, except for some national/regional differences. Also, PRIMARY (indicated by CAPS) and secondary (indicated by lowercase) allocations are slightly different.
