Thus, ABS&A may not use bands reserved for ground-based ARNS systems and GBS&A may

10、not use bands reserved for airborne ARNS systems. The sections below summarize the status of the ARNS bands from the Radio Regulations without prejudice to a specific band. It should be noted that there may be exceptions to this categorization that could be considered when selecting an appropriate b

11、and. For example, the bands from the other ARNS allocations category may also be appropriate for airborne S&A radars. Consideration should also be given to the need for ABS&A radars to use worldwide ARNS allocations rather than allocations for a single Region. Conversely, GBS&A radars only require a

12、llocations within regions and areas of the world where they will be used and allocations for GBS&A radars may be best considered within individual administrations. 4.1 Aeronautical radionavigation spectrum currently allocated for airborne radars There are currently five frequency bands allocated to

32、sors to support UAS operations as well as the current status of allocations that allow this usage. Tables 3 through 5 provide alternative bands that have allocations for airborne and ground-based applications of UAS S&A. As discussed in 3, ABS&A systems are constrained by UA SWaP. Also, weather or a

33、tmospheric attenuation must be considered when choosing spectrum for ABS&A because of the impact in meeting the operational requirements of the S&A function described in 2. GBS&A on the other hand is largely free from SWaP considerations and are less constrained by weather and atmospheric attenuatio

34、n. Thus, selection of the most suitable band for any particular UAS S&A Rep. ITU-R M.2204 15 application must consider performance aspects, which may be constrained due to available technology. Many of the existing ARNS are already in use and the existing users of these bands will need to be conside
