  • Relocate ISS to ME-L1   10 years 12 weeks ago

    Sorry about all them pesky words. Perhaps I should have used the "submissions" as news or white-papers on behalf of the topic(s) upon relocating ISS. Otherwise I'll certainly take your advice and post short links to specific pages that I'll externally manage on my site.

    I mistakenly thought this ISS forum (especially within the "General ISS forum") was all about sharing viable ideas and thereby obtaining feedback of other expertise, obtaining contributions and thus learning of what's possible.

    I don't suppose there's actually anyone available that can answer a few tough questions, or contribute something/anything along similar lines of relocating ISS to the moon?

    BTW; my summary update page is absolutely chuck full of lots more than what's ISS or even moon and LSE-CM/ISS related: http://guthvenus.tripod.com/update-242.htm

    One such page link is: http://guthvenus.tripod.com/lunar-space-elevator.htm

    In the mean time, I'll even edit those previous postings down to a dull roar.

  • Why ISS in packet mode   10 years 12 weeks ago
    [quote:f6c6116792="iz6byy"] Another question: how come that most of the ARISS contacts are dove OVER THE TELEPHONE? Is this amateur radio? I just dont undestand the telebridge reason to exist. I am sure that a valid reason (as valid as the reason that backs up the 1200 bd packet system) exists.[/quote:f6c6116792] Fact is that ALL of the ARISS contacts are done using amateur radio and much less than half (not most) use telebridge. In 2004, we had 25 direct and 9 telebridge contacts. Even when a telebridge contact is done, it still uses amateur radio for the uplink and downlink at the volunteer ground site. This is patched into a phone line to the school. I like to think of it as a really long mic and speaker. Scheduling issues related to the time that the crew is available (awake), when the school wants the contact (usually 9am-3pm local) and when the ISS is overhead dictate whether a direct contact or telebridge is used. Some schools request telebridge contacts because they do not have access to the necessary equipment needed to perform a direct contact.

    Brad,

    your topics are honest but this is a forum, not a place to post such long articles.
    Please keep posting your interesting articles on your site and not on this one. You are free to comment or advertize them here... not to post them all.

    Your long articles post will be deleted with no further notice. I am sure you will understand.

    Thank you

  • Relocate ISS to ME-L1   10 years 13 weeks ago

    Anything of religion or politics is out the window; Of relocating ISS to such a nifty station-keeping position (mutual Earth/moon gravity-well or perhaps best ever interplanetary gateway) was never intended as yet another argument as to politically or religiously why this task shouldn't or can't possibly be accomplished, as that's strictly the priority-1 and cold-war prime directive and for-profit motivation of most every other soul that's partaking in the ongoing sting, of those thousand points of light being their steadfast pro-NASA/Apollo or bust ruse of the century.

    This topic offers an honest application upon our using the known laws of physics, as backed quite nicely by well proven and thereby easily verified sources covering nearly all of the necessary expertise, of such efforts subsequently accomplishing the immediate pay-back as for the benefits of mother Earth, of our pillaging the moon itself, of otherwise accomplishing efficient interplanetary communications and of eventually benefiting actual interplanetary expeditions, as well as for accomplishing all sorts of viable space sciences.

    With direct benefits to most of humanity, that is if you'd dare to exprapolate upon such terrific benefits of extracting and subsequently redistributing various energy aspects of He3, and even on behalf of hosting star-wars capability isn't exactly a half bad notion. Identifying and hopefully defending mother Earth from NEOs is simply another win-win obtainable task that becomes doable once the tether dipole element and those massive counter-rotating flywheels beging storing sufficient energy.

    Instead of having to start the LSE-CM/ISS entirely starting from scratch, this topic is about our utilizing and/or making due with what we've actually got to work with, in a rather timely and affordable option as to otherwise continuing down the spendy and polluting mainstream path after those thousand points of light that simply don't exist (especially if you're Muslim), unless it's simply more of those reflections derived off the rather horrific waterfall of a bloated mainstream that has been misinterpreted as affording those points of light. As other than what's existing within the perverted mind-set of certain mad warlords and of their usual suck-ups as to whatever our administrations had to offer that bought far too much of humanity into this extremely intellectual dead zone, exactly as in the case of our taking the status quo hook, line and sinker over those WMD that never existed.

    In spite of the orchestrated flak and mainstreamism that's ongoing, I still believe that a few (perhaps damn few) individuals can honestly share and share alike on behalf of methods accomplishing this doable task of relocating ISS to the moon. I'll also have to expect that most other folks will remain content as the traditional collective that's obstructing at absolutely anything I'm suggesting. I know darn well that the talents, software and essentially all the resources have been out there, as mostly bought and paid for many times over by the public/taxpayer, that wwhich e've all been paying dearly for the last 4 decades worth of perpetrated cold-wars, of the sorts of supposedly smart folks that should have been on top of this nearby and easily obtainable quest as of years ago, not to mention of what Venus was having to offer as of the last decade, and of all things important has always been the Sirius star system that's gotten the cold-war sholder ever since the Dogon tribe informed us of what's what.

    Too bad the Dogon tribe didn't tell us about 9/11 or of all those WMD, as then we wouldn't have paid any attention whatsoever.

    Of course, before pushing ISS towards the moon, or of our doing much of a nything about the likes of Venus, much less Sirius, first we'll have to seriously boot the likes of mainstream religions and their ongoing incest of politics entirely out of the picture, performing an extensive anti-voodoo chant or exercisism upon the entire issue of those bogus moon landings (AI/robotic as well as manned), as to those issues being flushed once and for all down another one of our horrifically spendy cold-war space-toilets, as only then might honest folks get back into the business of making such good things and so much more happen.

  • ISS/AO-51 Disaster aid.   10 years 13 weeks ago

    No formal discussion but anyone is welcome to upload Health and Welfare traffic to the BBS so others can download and forward. Drawback being the same as with AO-51. ISS is only in range for less than 10 minutes at a time for 4-6 passes a day.

    Ascending passes are around 1400 UTC and decending passes are around 0000 UTC for that region.

  • ISS/AO-51 Disaster aid.   10 years 13 weeks ago

    AO-51 Configured for Earthquake/Tsunami Support

    In an effort to lend any assistance possible to the Earthquake/Tsunami
    disaster area, AO-51 will be will be configured and opened for use as a
    store and forward message satellite for those in the disaster area.
    Therefore the current schedule for AO-51 has been cancelled.
    The planned mode change to the FM Repeater in high power will not occur.

    AO-51 will be reconfigured at approximately 0305 UTC on 30 DEC 2004 to operate as a Store and Forward PBBS. The PBBS will still be open to general amateur use, but amateur operators should be ready to cease BBS operations at any moment, when we start to receive message traffic. We ask that all unattended PBBS operation stop until further notice. AO-51 PBBS users may be requested to help download and forward messages. More information about how amateur operators can help will be forthcoming.

    The FM repeater (Downlink 435.300 Mhz, Uplink 145.920 MHz) will be turned off to allow maximum power to be used on the PBBS downlink.

    The configuration for AO-51 PBBS will be:
    Downlink: 435.150 MHz, FM 9600 baud PacSat BroadCast Protocol (PBBS)
    Uplink: 145.860 MHz FM, 9600 baud PacSat BroadCast Protocol (PBBS)

    Anyone that can help contact those in the disaster area and inform them of the Satellite resource is encouraged to do so. Should another configuration of AO-51 be identified as providing more benefit to those in the disaster area, AMSAT will adjust AO-51's operating mode accordingly.

    Amsat and the Echo Command Team appreciate your help and understanding as we try and lend assistance.

  • Relocate ISS to ME-L1   10 years 13 weeks ago

    QUESTIONS (updated) on behalf of relocating ISS to the moon;

    1) what is the actual ME-L1 point, in terms of the average distance away from the moon or from Earth?

    2) what's the variation of the ME-L1 point, as the moon interacts with the gravity of Earth and the sun?

    3) how much sustained reboost will it take as for ISS exiting the gravity influence of Earth, coasting itself into the ME-L1 (gravity-well) zone at not much over 1 m/s?

    4) how much station-keeping energy will it require once ISS has parallel parked itself within this future LSE gateway or null-zone of ME-L1?

    5) What's the level of lunar reflected secondary hard-X-Ray dosage going to be like?

    6) What are typical cosmic background and direct solar radiation levels at ME-L1?

    7) How much of a physical impact from something encountered at 30+km/s can ISS currently withstand?

    8) Of continuing robotic re-supply deliveries of beer, pizza and fuel to ISS is needed how often?

    9) if necessary, how automated and thereby unmanned/robotic can ISS become?

    10) will a nuclear power generator or might a tether dipole element generate sufficient alternatives for station keeping?

    I'll eventually include your questions, edit as per adding to this list of my questions. I suppose I'll eventuall accomplish everything, that is if others still can't be bothered as to manage thinking of anything better to offer, propose or simply argue about.

    Basically the ISS would become orbiting Earth at roughly 322,400 km, thereby making 854 meters/sec about Earth, thus always in lunar alignment, although +/-2.75% linear and certainly of something +/- angular since absolute perfect alignment isn't going to transpire until the "Javelin Probe" is deployed as affording the ISS tether anchor, which in turn is essentially obtaining the initial LSE functionality and obviously giving something for ISS to pull against (within basalt/silica composite tether GPa).

    I believe the tidal forces would benefit whatever is within this nullification zone, simply because such slight amounts of planet/moon gravity exist, and certainly the leas population of atoms creating friction, thereby it's possible that a great deal of station-keeping energy could be derived from tidal forces, or I could be entirely dead wrong (wouldn't be the first time, nor the last mistake I'll make).

  • Relocate ISS to ME-L1   10 years 13 weeks ago

    Having ISS situated at the ME-L1 represents that whatever two-way radio/microwave communications and of whatever data streams/packets can become 100% amateur managed, as ISS travels itself along in total alignment with the moon that simply isn't zooming around Earth nearly as fast (well under 1 km/s at an average distance of perhaps 323,000 km) should only improve upon sustaining the up/down link. With ISS being consistently situated between the moon and Earth at roughly 323,000 km away from Earth is slightly more than a one second delay (2.15 seconds per round trip). Even optical laser communication becomes worth doing, as in using quantum photon binary format becomes technically good for at least 1e12 bps (such quantum binary performance is not there yet, but it's only a matter of time).

    Only the lunar secondary radiation of those hard-X-Rays is suggesting a slight radio interference problem, that plus getting signals to/from as having that rather nasty Van Allen zone of death in between, although of whatever's optical/photon represents the MUF factor has essentially become a non-factor, especially if there's more than one station transceiving upon managing such a nifty signal path.

    I truly believe a team of Russians, members of ESA and even the Chinese are fully capable of accomplishing this task within acceptable safety and cost limitations. The scientific rewards are certainly many that I can think of across the board on various lunar, Earth and of interplanetary benefits. Although, until more shielding is applied to our existing ISS, there should be somewhat greater risk for the crew, as well as their to/from commute of a few hours becomes days, but other than that there's only loads of absolute positives for robotics and eventually humanity and thereby of terrific Earth science that many can take directly to the bank.

    Silly me, here I was merely thinking that perhaps instead of folks continually sitting around and pretending there's absolutely nothing productive that can truly save ISS from reentering and thus burning up (I believe we've been informed that at times they're essentially out of primary rocket fuel, and that our shuttle will not likely arrive in time for the essential reboost ISS to 400+km, and that much below 300 km is almost toast because there's simply too much atmospheric drag for the onboard reboost thrusters currently available that can manage once the absolute minimum recovery altitude (point of no return) reaches 280 km.

  • Why ISS in packet mode   10 years 13 weeks ago

    It appears that your comments are for suggestions for amateur radio in general and not the program specifically on the ISS (although the could eventually be employed on ISS)

    I agree amateur radio developments have slowed but not come to a complete stop. AO-51 is capable of 38.4 K AX.25 transmissions (better than my current dial up at home). Several other advances in digital modes have come into use in recent years such as PSK-31, Hellschreiber and MT63.

  • Why ISS in packet mode   10 years 13 weeks ago
    [quote:80eb7ca86e="N5VHO"]The main purpose for amateur radio on the ISS is educational awareness. School contacts are the reason the equipment is there. All other activities are a BONUS.[/quote:80eb7ca86e] This is not the point. Whatever the goal is, the communication system should be efficient. Using a narrow band link is probably not the best choice for higly ham populated areas like Europe or North America. Wasting the majority of that data on useless DM frames or packet collisions is just a non-sense. How come the EarthKam project does not relay on amateur radio? Maybe because we are using tecnologies from the 70's? My point is that I just dont see any improvement since the MIR times. To me, it looks like that the rest of the world is rapidly evolving its communication means while the Amater Radio community remains stuck to the old fashioned stuff. They are using UMTS, Iridium, Sirius while we are using AX25 Packet, FM Voice and slow scan television. I think that we need innovations, and that we need them soon.
  • Why ISS in packet mode   10 years 13 weeks ago

    The main purpose for amateur radio on the ISS is educational awareness. School contacts are the reason the equipment is there. All other activities are a BONUS.

    Until Dec 2003, ISS was capable of 2 modes of communication, Voice and Packet. Since the crew is generally busy with other activities, the system was put in packet mode (until it stopped working) to aviod silence between school contacts.

    Since the addition of the Kenwood system, we have additional capabilities (such as the recent demo of the crossband repeater) but the packet mode is still the easiest to setup between the school contacts except for the afore mentioned silence (one power button push 8O )

    Long term plans should have multiple operations going on simultaenously but we still need additional equipment and testing before that happens. Since Columbia, those plans have been significantly lowered in priority and delayed.

    I'm always open to suggestions and ideas as to what can be done when the crew is not using the radio. Things already on the plate include SSTV, ATV, Packet, FM crossband repeater and some HF operations.

  • Why ISS in packet mode   10 years 13 weeks ago

    AX25 Packet Radio was not designed to operate on a space station.
    In facts, as I have been repeating in the last 10 years, most of the data coming down from the station is useless.
    APRS is nice, but do we really need an APRS repeated onboars the ISS? What for? I do APRS once every while but I find it boring and I really dont think its a primary reason for the amateur radio station to be up there.
    We, as Radio Amateurs, must find a modern and efficient way to use the amateur radio station onboard ISS. (Not necessairly cheap).
    AX25 is not efficient nor modern.

    4th reason ,, i got hooked up on aprs via the iss packet with out spending ANY money , and just useing my old 486 computer ,and a handeld radio, home made antenna, home made radio to computer interface , free uiss and agw programs !!! and it is a easer contact with packet then voice ,ie more contacts !! less power ,

    ok im cheep,,, well better put is im not rich,,, someday !!!

    ok and another good mode to try would be psk31,, there could be lots a contacts with that ,

    [quote:c6ece0e1c8]can ANYONE tell me WHY the ISS is always on packet mode? It is very ANNOYING!

Author - UNKNOWN[/quote:c6ece0e1c8] Patience Grasshopper.... Several reasons. 1. ISS is the only APRS/Packet operational satellite up there. 2. The repeater was only being tested for future full time implementation when additional resources are installed/recovered. (wait till the shuttle is flying again) 3. There are other voice repeater satellites already available (AO-51 for instance).
