Currently that is not an active system in the US. If it would re-occur outside of test-transmissions, then I am sure it would be included. The lack of other GNSS systems, including SBAS/NBAS such as WAAS and DGPS is also interesting. There is some politics in it, but it should not be relevant for the listing. For most parts, the list would have the same vendors, but more columns. Cheers, Magnus
