[20:29:25] NASSP Logging has been started by thewonderidiot [20:33:37] good old Guenter reboot [20:44:01] :P [20:51:51] haha [21:05:59] I know what the EDS needs [21:06:02] more relays! [21:30:50] night! [18:11:17] morning! [18:12:53] hey Mike [18:13:20] how's the new document? [18:13:48] better [18:13:52] much better [18:14:08] it's not handwritten, so that's already 1000% improvement [18:14:29] :D [18:14:36] did you also get your scans? [18:14:48] nope [18:14:53] maybe next week [18:15:04] right. well, I already a bit longer :D [18:15:08] already waited* [18:15:11] Ron sent me this: [18:15:12] > I tried to do these scans today, but I turned out to be unequipped to do so. (The reports' bindings are protected with tape, causing NARA to decline to remove the staples, which would have made the scanning rather inferior with the stuff I had along with me today.) At any rate, the boxes remain on the cart, as opposed to having been reshelved, and I expect to try again, probably next Thursday. [18:15:31] ah [18:15:40] always a risk with paper documents [18:15:49] you don't really know what format you are getting [18:17:15] Ron should already be experience with these MSC memos though :D [18:19:38] hahaha [18:19:40] yeah it's weird [18:19:47] I've never seen any MIT reports with tape on the binding [18:20:22] or staples really [18:20:29] so this must be a different sort of thing [18:22:16] unusual is usually interesting [18:25:03] hopefully :) [18:26:10] the new LOI document does not have more explanations, but I should be able to implement it just like in the document [18:26:29] and then experiment with some of the inputs to the LOI processor I still don't 100% understand... [18:27:02] which are some of the same inputs as the TLMCC processor [18:29:49] huh [18:29:53] what kind of inputs? [18:30:31] and altitude bias [18:30:32] an* [18:30:52] and then you can specifiy how many orbits there are between LOI and DOI/LOI-2 [18:30:58] usually that would be 2 [18:31:10] but you can input a non-integer number [18:31:28] which probably goes together with a true anomaly you can specify for the LOI TIG [18:32:09] those inputs have to be the way you rotate the orbit during LOI so that the post LOI orbits aligns with the landing site [18:32:17] LOI orbit* [18:32:47] ahh interesting [18:33:09] I'll continue listening to the Apollo 13 FIDO loop until MCC-2 [18:33:28] maybe there are more hints [18:33:43] already this exact TLMCC and LOI processor versions were not fully done until Apollo 14 [18:33:52] but Apollo 13 did plan to do the CSM DOI maneuver [18:34:11] although this exact* [18:34:52] it could be that the magic lies in having the right inputs selected before the flight already [18:36:18] I think I'll try to fully implement the LOI targeting and experiment with that to understand the inputs better [18:36:28] than I can get back to the TLMCC targeting and apply my new knowledge [18:36:43] sounds good :D [19:06:00] nice [21:03:57] night! [17:45:12] morning! [17:53:16] hey Mike [17:53:29] what's up? [17:54:40] making good progress with implementing the LOI targeting [17:55:02] it's weird, I understand the math quite well, but not all the intentions behind the math. Usually it's the other way around [17:55:14] hahaha [17:55:18] that is weird :D [17:55:34] and you? [17:59:08] got my new scanners set up [18:00:01] a replacement flatbed, and a new autofeed scanner that Ron recommended, that can do 35 double-sided pages a minute [18:00:30] so if that works out I should be able to go a lot faster :D [18:01:29] Ron is definitely a good person to ask about scanning [18:02:47] I tried it out on an MIT report that I have here and it worked great [18:03:18] and now I really wish I had this for, say, the astrionics system handbook :P [18:04:31] haha, those scans were quite decent though [18:05:07] yes but also they took hours and hours and hours [18:05:13] right [18:06:04] this scanner should look just as good, just be way faster :) [18:06:36] also the new flatbed has a built-in foldout mode, where you can scan two halves of something and it automatically stitches [18:06:40] which will be super convenient [18:07:03] that does sound great [18:08:35] anyways [18:08:45] other than that, I'm back to punch-card-ifying retread 44 [18:09:04] which is taking forever because of how many comments there are in the interpreter [18:09:34] many comments is a good thing :D [18:10:09] I am rather tempted to keep on working on the Saturn ground computer stuff. I really think I can implement something like ATOLL and let it run checkout programs. [18:10:30] that would be a lot of fun [18:10:46] that's what the LCC MFD would be used for, selecting and running the programs [18:11:05] I can use the same format as the actual ATOLL programs [18:11:06] that would be super cool [18:11:09] I have snippets of examples [18:11:26] most are about the EDS test actually, my favourite [18:11:50] probably because it's a quite complex checkout, with many inputs and outputs [18:12:43] there are some papers on Saturn checkout from back in the way, that's where the ATOLL examples are from [18:13:49] the format would probably be .csv files [18:13:56] which are loaded and then run [18:14:16] easy to change with Excel or so [18:14:21] oh I didn't know we had actual ATOLL examples [18:14:58] very little [18:15:09] and there are several versions/revisions of ATOLL [18:17:49] https://cdm16608.contentdm.oclc.org/digital/collection/p16608coll1/id/4094 [18:19:32] oh cool [18:20:44] and there is a super low res, one page of the EDS test procedure [18:20:58] where it is taken as an example [18:22:41] I would still have to derive the e.g. EDS test from what I written down listening to the Apollo 11 audio loops [18:22:56] but even then, that's pretty fun [18:23:37] hehehe yeah that adds another level of interesting to it [18:25:33] if we had the real test programs and could properly run them then the Saturn systems get a checkout as good as running some Aurora self tests :D [18:26:56] I'll have to check if I can also find the Apollo 13 EDS test [18:27:16] the Apollo 11 one is faintly in the background, with people in MCC-H talking all the time [18:28:00] haha ouch [18:28:03] that sounds super annoying [18:28:22] it's quite often the case, on all loops [18:28:33] what we are hearing is what the flight controllers were hearing [18:28:47] so often multiple loops at once [18:29:11] the Apollo 11 FIDO during the lunar landing was more interested in the astronauts than his back room people... [18:29:45] the Apollo 13 FIDO loop has been better so far [19:45:13] my PC had performance issues in the last few hours [19:45:38] the solution? I had the screenshot of the LOI Targeting display in MCC-H open, in the Windows Photo application [19:46:01] which apparently has a memory leak or something, it was using insane numbers of RAM [19:46:23] Microsoft makes great applications [20:10:19] hahahaha wow [20:10:38] that is impressive [20:38:42] halfway done with the interpreter [20:38:47] and done with the fixed-fixed portion I think [20:42:44] very nice [21:31:45] night! [18:08:18] morning! [18:13:21] hey Mike [18:15:23] what's up? [18:16:15] working a bit more on ATOLL and the EDS [18:18:36] I can load a .csv file and process the lines from it [18:18:42] nice :D [18:18:44] I have two operators currently [18:18:50] wait for X milliseconds [18:18:54] and issue discrete output [18:19:04] only just started testing it, but it seemed to work [18:19:19] building a longer test file now for more tests [18:20:27] and I am adding a bunch more relays to the EDS, usually ones with the same function but that have redundancy [18:20:41] as the ground computer can issue separate signals to each [18:22:13] no single relay failure was allowed to cause problems [18:22:27] so there usually is 3 relays, and they vote 2 out of 3 before doing something [18:28:07] makes sense [18:28:21] did you ever get a newer Saturn handbook that has EDS? that was missing from the 503 one wasn't it? [18:29:32] yeah, you convinced me to request the AS-508 Handbook :D [18:29:38] had the whole EDS [18:29:56] minus lots of GSE commands and measurements [18:30:03] but that has been very helpful [18:30:21] hmm [18:30:35] can you send me a link to that? we should get that on the virtualagc website [18:30:39] I think I missed it [18:31:02] sure [18:31:18] got it from UHCL, so I'll upload it [18:33:16] it's pretty great [18:42:20] thanks! [18:43:48] no problem
