Who it is for
Anyone who would rather read the series on a tablet or print it than follow seven pages: a carrier strategist, an investor or a vendor working on satellite-to-phone.
What is in it
- Seven parts as chapters, each with its In brief box, numbered exhibits and sources
- A contents page with page numbers and PDF bookmarks for every part
- Method and limits for each part, and the data-as-of date for every figure
- Running headers and footers with the page, the part and the edition
What it will not do
It adds nothing to the parts on the website and takes nothing away. Corrections are published on the website first, so where the two disagree the website is later and governs.
Sources
FCC licence files and orders, SEC filings and orbital elements, as cited in each part. Second edition, October 2026, with SpaceX's 800 MHz agreement of 8 October 2026 and the FCC's orders of 1 July and 6 October 2026.
