- KO-25 NASA Keps Track The Wrong Satellite
-
- For the past several weeks many amateurs have noted that the NASA keps for
- KO25 have not produced accurate AOS and LOS times observes AMSAT-NA Orbital
- Data Manager Ray Hoad (WA5QGD). With the help of W5IU, K5EKH, and KG5OA,
- numerous KO-25 passes have been observed in conjunction with other objects
- in the KO-25 launch group. The consensus of this study is that the object
- NASA tracks as Catalog #22828 may actually be KO25.
-
- In order to help remove this confusion, the keplerian elements for
- Catalog #22828 will be included (for the near future) in the weekly kep-
- lerian element set published on INTERNET. Please post any comments on the
- accuracy of the Cat. #22828 keps in tracking of KO25 as messages addressed
- to WA5QGD on either KO-23 or KO-25 digital satellites. The NASA Orbital
- Information Group has been advised of the tracking problem with KO25.
-
- Note: The most accurate way to determine whether a transmitting satellite
- fits a set of keplerian elements is to observe the frequency of the
- satellite's transmission at the Time of Closest Approach (TCA). For
- low orbit birds, this corresponds to the time of maximum elevation given
- by most tracking programs. At this time there will be no doppler shift
- and the transmission frequency should match the published channel frequency
- (assuming no shift due to other causes). If a set of keps meets these
- requirements, it is a good match for the satellite. This method will
- give more consistent results than the AOS/LOS method.
-
- [The AMSAT News Serive (ANS) wishes to thank Ray Hoad (WA5QGD) for this
- bulletin item.]

- Join these sessions or contact wb6llo@amsat.org for other skeds and he
- will coordinate your efforts.

- AO-13: Current Transponder Operating Schedule:

- Mode-B : MA 0 to MA 90 | Omnis : MA 230 to MA 30
- Mode-BS : MA 90 to MA 120 |
- Mode-S : MA 120 to MA 122 |<- S beacon only

- Mode-S : MA 145 to MA 150 |<- S beacon only
- Mode-BS : MA 150 to MA 180 | Blon/Blat 180/0
- Mode-B : MA 180 to MA 256 | Move to attitude 230/0, Sep 12

- N QST *** AO-13 TRANSPONDER SCHEDULE *** 1994 Sep 12 - Dec 19
- Mode-B : MA 30 to MA 150 |<- OFF Oct 22 - Nov 07 for eclipses
- Mode-B : MA 150 to MA 190 | max duration 2h 12m
- Mode-BS : MA 190 to MA 218 |
- Mode-S : MA 218 to MA 220 |<- S beacon only

- Mode-B : MA 230 to MA 30 | Alon/Alat 230/0
- Omnis : MA 250 to MA 140 | Move to attitude 180/0, Dec 19
- The battery charge state is of paramount importance during the eclipse
- seasons. As always the command team may have to have to make temporary
- changes to the published schedule. In that case we will try to minimize
- the inconvenience, setting Mode-B OFF from MA 230-256 in the first
- instance.

- DO-17: DOVE is running a new set of software that tests the
- digital-to-analog converter (DAC) and other hardware and software cap-
- abilities. It plays digitally generated tones through the DAC and exer-
- cises software that implements two way communications between the on-board
- processors. [WD0E for the DOVE Team]
-
- RS-10: RS-10 has been working very well. Lots of activity with 2 stations
- worked /MM I6KYL/MM EL27 and N1KTM/MM EL67. Also on the 28-JUL-94, WC9C
- heard the station KC6VRK who was on AO-13 as RS-10 pass underneath right
- after AO-13 went through its perigee; his signal was very strong on the 10M
- downlink. The CW Robot is back up and working just fine. Also, WA6ARA
- reports that RS-10 has been sending down excellent signals at his QTH with
- lots of stations using CW. [WC9C & WA6ARA]
-
- AO-10: After last week's glowing report about AO-10 sending down excellent
- signals, ZL2TPO reports that AO-10 has started to "FM" very badly. Up
- until last week it has been operating quite well and there have been a
- number of stations operating. Please note that when AO-10 is "FMing,"
- please refrain from using it. [ZL2TPO]
-
- KO-25: WH6I reports that KO-25 was in some sort of "loader-mode" earlier
- in the week. Today, however, the BBS seemed to be working again, but he
- was unable to send any commands to it. WH6I has not seen anything to
- indicate what is going on. [WH6I]
-
- LO-19: LUSAT-OSCAR-19 (LO-19) is still not running its BBS. [WH6I]
-
- IO-27: WH6I still has not heard anything from ITAMSAT. [WH6I]
-
- AO-16: Still going strong and very doing well. There is some gateway
- traffic on AO-16 but not enough to present any problem to other users and
- the file lifetime on the bird is still quite long. [WH6I]
-
- KO-23: KO-23 is going strong and doing well. [WH6I]
-
- The AMSAT NEWS Service (ANS) is looking for volunteers to contribute weekly
- OSCAR status reports. If you have a favorite OSCAR which you work on a
- regular basis and would like to contribute to this bulletin, please send
- your observations to WD0HHU at his CompuServe address of 70524,2272, on
- INTERNET at wd0hhu@amsat.org, or to his local packet BBS in the Denver, CO
- area, WD0HHU @ N0QCU. Also, if you find that the current set of orbital
- elements are not generating the correct AOS/LOS times at your QTH, PLEASE
- INCLUDE THAT INFORMATION AS WELL. The information you provide will be of
- value to all OSCAR enthusiasts.

- Subj: STS-65 Commemorative TLI Burn
- File: TLI.sit (58540 bytes)
-
- MacSPOC Users-
-
- During STS-65, you'll recall MacMission Control supported targeting of a
- commemorative TransLunar Injection (TLI) burn. Time of IGnition (TIG) for
- this burn was 25 years to the minute after a similar TLI was performed by
- Apollo-11 to break free of low earth orbit. The commemorative TLI was
- tageted to reach a point 100 miles above the moon's farside 25 years to
- the minute after Apollo-11's Lunar Orbit Insertion (LOI) burn TIG.
-
- With targets from MacMission Control, Flight Dynamics Officers (FDOs) in
- the real Mission Control filled out a Pre-Advisory Data (PAD) for the
- commemorative TLI burn. This PAD, together with plots of STS-65's
- post-TLI trajectory relative to the earth and moon, are enclosed as 3
- TeachText documents for your viewing pleasure.
-
- An image of the commemorative TLI PAD was uplinked as a FAX to the STS-65
- crew around 8:30 AM CDT July 16, 25 years after Apollo-11 was launched.
- Upon receiving the PAD, STS-65 Commander Bob Cabana remarked, "Don't we
- wish!" Powered Explicit Guidance mode 7 (PEG 7) targets computed by
- MacMission Control appear on the PAD as an in-track speed increase of
- 9586.3 fps, a northward cross-track velocity change of 3073.7 fps, and a
- radial upward velocity change of 5944.0 fps. Using both Orbital
- Maneuvering System (OMS) engines for a total thrust of 12000 lbs, Columbia
- would have required a TLI burn duration (TGO) of 2 hrs 03 min 24 sec to
- build up these velocity changes. Actual OMS fuel available to Columbia at
- TLI TIG would have supported less than 5 min of 2-engine burn time, and
- most of this was allocated to STS-65 deorbit.
-
- It's worth noting Apollo-11 weighed nearly 200000 lbs at TLI TIG, only
- about 45000 lbs less than Columbia's WT on the commemorative PAD. Unlike
- Columbia, however, about 75% of Apollo-11's weight was propellant to feed
- the Saturn IV-B's single J-2 engine during TLI. Because the J-2 developed
- about 200000 lbs of thrust, Apollo-11's TLI required less than 6 min to
- perform.
-
- The 2 post-TLI plots are in the ecliptic plane. This is coincident with
- earth's orbit around the sun. The moon's orbit about earth is less than 5
- deg from the ecliptic. The Vernal Equinox indicated on these plots is the
- Sun's apparent position as viewed from earth when Spring begins in March.
- The Sun's position in mid-July is also indicated on the plots.
-
- Does anyone have a guess as to when the next (manned) TLI burn will be
- performed for real?
