The comparison of velocity residuals between ground tracking data
and the onboard system, as calculated along the earth-moon line-of-sight,
provided an additional check on the performance of the primary guidance
system. A residual of 2 ft/sec was recorded at acquisition of signal
and provided confidence that the onboard state vector would have only
small altitude and downrange velocity magnitude errors at powered descent initiation. The Doppler residual was computed by comparing the
velocity measured along the earth-moon line-of-sight by ground tracking
with the same velocity component computed by the primary system. As the
lunar module approached powered descent initiation, the Doppler residual
began to increase in magnitude to about 13 ft/sec. Since the earth-moon
line-of-sight vector was almost normal to the velocity vector at this
point, the residual indicated that the primary system estimate of its
state vector was approximately 21 000 feet uprange of the actual state
vector. This same error was also reflected in the real-time comparisons
made using the powered flight processor previously mentioned.
121:00:34 Evans: And for your information, we're also going to have Tranquility Base do a P52 (means P22, tracking the CSM with the LM's rendezvous radar) when you come around the other (means 'next') time. And I have the P22 (landmark tracking from the CSM) information if you're ready to copy. (Pause)
[In a 2010 book, From the Trench of Mission Control to the Craters of the Moon, H. David Reed, who was Flight Dynamics Officer (FIDO) for the Apollo 11 LM liftoff, details the story behind this unscheduled request for a P22 one orbit before liftoff. Briefly, he and his support team needed an accurate LM position so they could pick a liftoff time that would minimize propellant usage. The various estimates available at that time were scattered over a considerable area. They needed something better. After extensive discussions within the team, Reed choose a method suggested by Pete Williams, the COMPUTER DYNAMICS officer: they would track the CSM with the LM's rendezvous radar and, then, using a separate, accurate determination of the CSM's orbital track over the landing site (as discussed at 121:07:37), work backwards to find the LM.]
however after his request of tranquility base doing a P52 and relaying those data figures (which is the reverse rendezvous radar solution) this is i believe to be the final solution used for L/O which should be the number you used as the MSFN solution. which is 0.631N and 23.47E.
Apollo is not alive but was recorded and the capcoms edit in and this is how they edit in with the quindar machine and i am very honest that i read this somewhere else so it is not my original idea
i study apollo a lot mostly because i learned it was sony when i read parts about how the astronauts said they sighted stars i am a sailor but mostly a navigator and have won many awards with my sextant even when i was a little boy and this is how i learned apollo was fony comparing the astronauts stores with how i do things and know about sighting stars
so the quindar beeps are editing marks for the apollo mission movies and that solves the mystery
my reading is good but my writing not so good and my sister says she will help me sometimes answer your posts because her writing is good
I have been interested in the phoniness of the recordings by NASA during their space flights. I believe that they really do know what happens out in space and possibly in direct communication with alien life. I still wonder what is really on the moon, and what we left behind.
What do you think of the now defunct NASA missions and the private sectors space projects being sent into space.
The reason is that Apollo can not be live because if it was when neil made a mistake liked coughed when he wash't supposed to cough or someone got nervous and made a mistake then we would all know that Apollo was fony so first we know the apollo missions the sound recordings like the voice transcripts and the films like the moon videos to are recorded before the astronaut part is recorded and then played this way they are perfect and no one makes a mistake but then the capcoms say things over the recording and that part is alive but the capcoms have rehearsed many times and have something to tell them what to read
