SES Problems With EPFD Data Resolved: SpaceX

SES, claiming there are flaws in SpaceX's equivalent power flux density data files for its proposed second-generation constellation (see 2202090002), could have resolved the issue by reaching out, SpaceX told the FCC International Bureau Wednesday. It said the problem came from SES using a freeware version of Transfinite's software made available on the ITU website, which lacks a table available in the commercial version. SpaceX said it gave SES a new version of the data. SES said the new files come "almost two months after SES first flagged that SpaceX’s EPFD files were incompatible with the ITU software." It said it's reviewing the files but it's too soon to say whether the anomalies have been eliminated. It said they "do not address the more fundamental defect with the SpaceX EPFD showing" or show the second-generation satellites together will meet EPFD limits, let alone whether the combined first- and second-gen constellations will.
