My 2001 copy of Uplink-Downlink was printed by GPO and is 674 pages of 10-point type. I would not want to scan it! Anyway, it was only $25 from an Abebooks seller including tax and shipping and is in near-new condition including a plastic-wrapped dust jacket. Jeremy On Mon, Jun 8, 2020 at 1:01

Abe Books has several copies of the hardcopy. https://www.abebooks.com/ $30. Check the fine print. At least one says print on demand. My copy is in near perfect condition. Page 127/8 is a 3 page fold out diagram. It's 650 pages, way more than I will ever read, but if somebody sends a note

My copy is an original, bought from one of the Abebooks sellers. It’s a huge book and the type is on the small side; I’m still working my way through the Introduction. Looks like a lot of good information. Jeremy On Mon, Jun 8, 2020 at 5:23 AM Wannes Sels wrote: > I bought a used copy of

I also bought my copy of "Uplink-Downlink" through Amazon but had better luck. The cover photo is in color, not quite as sharp as I would have preferred but has no apparent compression artifacts. The text inside is of good quality- nop complaints in this department. However, the photos inside

Hi Jim, This explains a lot of things. As an old time user of the Moon Bounce time synchronization in the Madrid Space Complex, I can say that the system was never popular among the users, it was cumbersome to use and there were already other systems with better accuracy and availability,

Apparently, they used moonbounce between DSN stations to synchronize to 5 microseconds in 1968. It was easier and cheaper than flying cesium clocks around. (And the Rb standards weren't good enough). https://ntrs.nasa.gov/search.jsp?R=19770007245 History of DSN - mostly about politics,
