ensuring that the availability of even a near-optimum single star would be sightable by the system required access to a large computerized star map which did not exist at the time.
Just how many bytes do you think it would take to catalog the 100 brightest stars? And why would you consider so few bytes to be "large"?
Of course the Apollo ships were alleged to have flown by way of stellar-inertial guidance through cislunar space, a region also never employed as a vantage for the development of detailed computerized star charts.
"vantage"??? Bwahahahaha! Do you have any idea how little the closest star to us would change its position if viewed from the Earth and viewed from the Moon? This is right along the ignorant claims that NASA didn't include stars in the lunar surface pictures because astronomers would be able to tell the stars weren't in the proper position as viewed from the Moon.
What would any given scope see from cislunar space?
Stars! Stars that were about 30% brighter than viewed from the surface of the Earth because the Earth's atmosphere absorbs about 30% of the star light reaching the surface (minus optics losses).
No one really knew much at all, least of all anything as regards details given the equipment the Apollo ships were to carry; scanning scope and 28 power sextant.
Nonsense.
For Apollo guidance, several dozen stars were "memorized" by the computer and then supposedly found by the astronauts with help of the computer and so the inertial platform was aligned on the appropriate occasions. What baloney that is.......
This nonsense again???
How do you think ships check the errors of their gyros when out of sight of land? By sighting celestial objects and comparing the calculated bearing to the bearing obtained with an alidade or periscope. If you know your approximate position and exact time you can use the Nautical Almanac and a Sight Reduction Table to calculate the bearing to any of the listed celestial bodies (the 57 "navigational stars", Polaris, the Sun, the Moon, and Venus, Mars, Jupiter and Saturn. This is what an alidade looks like:
Chapter 17 of the American Practical Navigator aka "Bowditch" aka the Navigator's Bible has the procedure. The entire book in PDF is available for download for free here: http://msi.nga.mil/NGAPortal/MSI.portal?_nfpb=true&_pageLabel=msi_portal_page_62&pubCode=0002
Here is a screen cap of the first page for those who know I know what I'm talking about and don't want to read the whole chapter:
Is there anything in Chapter 17 that says you cannot use celestial bodies to determine gyro error?
Such a scenario for actually sighting stars and aligning a platform in 1968(Apollo 8) was simply not viable at the time.
There is plenty of evidence that there was in NASA's Technical Reports Server including the tests conducted on the systems.
Draper was a dyed in the wool gyro enthusiast and stated in an interview, "if you have a good enough gyro, you wouldn't need a star tracker". Draper thought putting a stellar sensor in a Polaris ICBM inertial system was like applying a "band-aid" to something that did not need one.
Polaris flew for 30 minutes and Apollo for 10 days so the comparison is extremely poor.
As of the late 60s, there was no functional star sighting equipped inertial guidance system for Polaris, or for ANY ICBM American or Russian for that matter.
The Lunar Orbiters you have grossly been citing as proof that Apollo was hoaxed used star trackers.
D'oh!
So sure a stellar-intertial guidance system was built for the Apollo ships that were pretending to carry men to the moon. But certainly the deployment of these systems in the craft was not a functional deployment.
Ill-informed speculation.
There were no supra-atmospheric/cislunar star charts available detailing relationships
Bwahahahaha! Dude! The nearest star outside our Solar System is 25 trillion miles away. Twenty five trillion miles. That is a 2 and a 5 followed by 12 zeroes. 25,000,000,000,000. Miles.
That is ~100 million times farther than the Moon.
Dude! Learn a lot more about the universe you live in.
so in the parlance of the military researchers "near-optimal" stars could reliably and consistently be sighted. There is no way astronauts would be able to reliably and constantly discern one star from the next whether presented with a paucity of stars or an abundance.
Absolutely no way except the way man has done it for millenia: by using their eyes and identifying the pattern of brighter and dimmer stars. Then there is the method of telling your scope where to point and then looking through the scope.
They did not even have functional stellar guidance for earth "orbiting" missiles at the time of Apollo 8, 11, 12 and so on. NONE!!!!!!
So you are admitting the Lunar Orbiters were hoaxed too?
Of course they wouldn't shoot three guys into space in 1968 (Apollo 8) HOPING they would see the right stars with that hokey equipment with it never having been tested
It was tested on Earth and it was tested on Apollo 7!!!
HAVE TO BE ABLE TO ACCURATELY SIGHT STARS IN CISLUNAR SPACE TO ALIGHN THE PLATFORM.
Which is why that had a sextant installed.
THERE IS ZERO TOLERANCE FOR ERROR,
More layman ignorance without supporting evidence.
AND THE FACT THEY SENT THIS THING, APOLLO 8, INTO SPACE WITHOUT AN UNMANNED TEST PROVES THE ENTIRE APOLLO PROGRAM FAKE IN NO UNCERTAIN TERMS.
See above. Star trackers had already been used on numerous unmanned probes. The Apollo sextant was tested on Earth. Why would it need to be tested in space? Does zero-g and a vacuum somehow change the fact that there are 360° in a circle, 60' in a degree, and 60" in a minute of arc?
Remainder of your ignorant repetitive childish rant deleted.
