I began to study Apollo one year ago.

Having to use stars for navigation was obsolete by the time the Apollo missions occurred.Navigation was controlled by mission control not the astronauts. Listen to the course correction mission control tells them when and for how long to fire thrusters it was all plotted by computers on the ground.Originally they believed the astronauts would be plotting there course, but with some advances made it proved to be better for mission control to handle it.So your argument kind of disproves your theory actually.Why have something redundant that was no longer needed if they faked it?
These star charts were used by astronaut and Command Module Pilot, Michael Collins, during training sessions prior to the Apollo 11 mission launched in July 1969.
Star charts were an important piece of navigation equipment used by the astronauts during the Apollo missions, enabling them to fix their location at any given time.
These star charts were donated to the National Air and Space Museum by Michael Collins in 1985.
The inertial navigation system on the Apollo spacecraft was tightly integrated with the guidance computer itself. They were effectively one machine. The exact orientation of the spacecraft was critical to the computer-controlled rocket firings so that orientation had to be as accurate as possible. But gyros drift, and the INS could not keep its orientation accurately enough for more than about a day. That's when the astronauts got to shoot the stars. The procedure was known as "P52" (program 52) and it was as close as the astronauts came to manual navigation for the most part. In P52, the astronaut would re-align the inertial platform by requesting a particular star out of the standard list of 37. The computer would then electronically point the sextant at the expected position of that star. The astronaut would then look through the sextant (which had a high magnification for a sextant: 28x) and he would adjust the pointing by a few hundredths or a few tenths of a degree until the star was right on the crosshairs. He would press a button. The computer would read the offset in angle electronically to a precision of a thousandth of a degree, and the pointing error would be displayed. The astronaut would then accept or reject the adjustment and repeat the procedure with a second star. That was it. No manual reading of scales. No paper calculations or table look-ups. No adjustments for refraction or "irradiation" or anything else. You'll note that this "P52" process was really using the sextant as an astro-compass: the angles were relative to the orientation of the ship, not angles between celestial bodies.
Sorry to bust up Apollo's little party DJW001, but with all due respect, they really do need, NASA does, to trot out a couple of their docs to debate me.
Bluff all you like DJW001, but truth is, and we all know it here, as regards the phony Borman cislunar diarrheal illness, Shepard's bogus Meniere's disease cure, Slayton's a-fib issue, no one has ever effectively countered my claims and associated air tight demonstration of Apollo Inauthenticity. And in the world of Apollo, it is indeed I, decisively, and a half dozen friends who are the experts here, experts without peer.
Interesting you find me so ill informed. I believe it was you not but two pages back that suggested the IMU/platform could be aligned by way of uploading data from the ground tracking system. Call me what you like, but if I am ignorant/naive, what does that make you DJW001 ? Perhaps the most fundamental aspect of the entire optics/guidance/navigating system and you had not a clue ? So let's cut it with jive JDW001, I run circles around Chaikin, Harland, and you when it comes to familiarity with Apollo's real history, not to mention my familiarity with the fundamentals of their imaginary machines. I am thrice as smart, thrice so well informed, and that is quite literally a fact, despite my short time seriously investigating these shenanigans.
By the way, I've nailed another, none other than NASA's once celebrated Public Address Man, Jack King. I know I need not encourage you to check out my upcoming posts as regards the good Mr. King and how he was a member of the crew that screwed us all so good, your heroes, THE MAVENS OF LUNAR CHARADE. Despite your words suggesting mine to be a mind operating but a plane above that of half moronic, oh my DWJ001, how you do ever so follow my every post !!! One life to live and you spend so very much of yours in this ever so anemic effort to counter me.
Why is that DJW001 ? Why spend so many precious hours of your life battling a "kook". I certainly have not been able to figure it out, your fascination with my "platform", a platform with its own most recalcitrant attitude.
Why is it DJW001 that you read my posts and spend so much precious time with me ?
Borman took seconal twice, the second time, to intentionally try and give himself diarrhea in outer space. This, in an effort to have his cabinmates aspirate his own stool ?
Have you thought of trying the 'official debates' forum on here? You can offer to debate someone on a specific topic, get someone else to agree and get the mods to set it up. There's a set format and set rules so that nobody can get an advantage, and then the mods assess the quality of peoples posts and post their verdict.
