Therefore, no other transponders or beacons are active. Since control of this spacecraft was lost, transponder operations must be made according to schedules provided by the satellite controllers. *** UO-11 UoSAT-OSCAR 11 -------------- NASA Catalog Number: 14781, Launched on 01-Mar-84 Orbit : Low-altitude, circular, sun-ynchronous, near-polar Beacons include: 145.826 MHz NBFM, 5 KHz deviation, 400 mW output AFSK, LHCP antenna 435.025 MHz NBFM, 5 KHz deviation, 600 mW output AFSK, PSK, LHCP antenna 2401.500 MHz NBFM, 10 KHz deviation, 500 mW output AFSK, PSK, LHCP antenna This is an experimental research satellite that contains no active linear transponders. A Digital Communications Experiment (DCE) is available to investigate digital "store-and-forward" communications techniques and various packet radio protocols for use in future satellites containing digital transponders. On-board experiments are designed to be of interest to amateur radio operators and science educators in the study of the near Earth space environment, including the Earth's ionosphere and magnetosphere. The VHF beacon carries 1200 baud telemetry, whole-orbit data, DCE downlinks Digitalker audio, and news, and is continuosly active. The plain-text news bulletins originate from AMSAT-UK and are carried as standard ASCII having one start bit, 7 data bits, 1 even parity bit and 2 stop bits. Bell 202 modems may be used for demodulation if the demodulated data stream is inverted. Synchronous AFSK modulation techniques are used. One cycle of 1200 Hz tone = "0" Two cycles of 2400 Hz tone = "1" The higher frequency beacons can carry 4800 baud downlinks from the Digital Store and Readout (DSR) experiment, where CCD imager data is stored, along with data from other on-board experiments. This spacecraft was the first amateur satellite to operate under a Forth operating system. The primary on-board computer is an RCA 1802. It was also the fastest satellite ever built, going from design to launch in just 6 months! *** RS-10/11 Radio Sputnik 10 ---------------- NASA Catalog Number: 18129, Launched on 23-Jun-87 Orbit : Low-altitude, circular RS-10 Frequency Chart --------------------- Uplink Passband Downlink Passband Mode K 21.160- 21.200 MHz 29.360- 29.400 MHz Mode T 21.160- 21.200 MHz 145.860-145.900 MHz Mode A 145.860-145.900 MHz 29.360- 29.400 MHz Mode KT = Mode K or T uplink with BOTH K and T downlinks. Mode KA = BOTH Mode K and A uplinks into a common Mode K or A downlink. CW Beacon Frequencies: 29.357, 29.403, 145.857, 145.903 MHz Autotransponder ("robot") uplinks: 21.120 and 145.820 MHz RS-11 Frequency Chart --------------------- Uplink Passband Downlink Passband Mode K 21.210- 21.250 MHz 29.410- 29.450 MHz Mode T 21.210- 21.250 MHz 145.910-145.950 MHz Mode A 145.910-145.950 MHz 29.410- 29.450 MHz Mode KT = Mode K or T uplink with BOTH K and T downlinks. Mode KA = BOTH Mode K and A uplinks into a common Mode K or A downlink. CW Beacon Frequencies: 29.407, 29.453, 145.907, 145.830 MHz Autotransponder ("robot") uplinks: 21.130 and 145.830 MHz RS10/RS11 are two amateur radio transponder packages attached to COSMOS 1861. Each transponder is identical, although the frequencies each uses are different. "Robot" operation involves sending "RS10 DE (your callsign) AR" using Morse telegraphy between 10 and 40 WPM. Successful contact with the autotransponder will yield a QSO number. *** AO-13 AMSAT-OSCAR 13 -------------- NASA Catalog Number: 19216, Launched on 15-Jun-88 Orbit : High-altitude, elliptical, synchronous transfer, Phase 3, Molniya AO-13 Beacons include: Mode B General : 145.812 MHz Mode B Engineering : 145.985 MHz Mode JL General : 435.652 MHz Mode S General : 2400.664 MHz Transponder Uplink Passband Downlink Passband Mode B 435.423 MHz.. 435.573 MHz 145.975 MHz.. 145.825 MHz Mode J 144.423 MHz.. 144.473 MHz 435.990 MHz.. 435.940 MHz Mode L 1269.641 MHz..1269.351 MHz 435.715 MHz.. 436.005 MHz Mode S 435.602 MHz.. 435.638 MHz 2400.711 MHz..2400.747 MHz RUDAK Uplink 1269.710 MHz (Inoperative) RUDAK Downlink 435.677 MHz (Inoperative) The General Beacons provide text messages and selected telemetry data in formats including CW (5 minutes on the hour and half hour), RTTY (5 minutes at 15 and 45 minutes past the hour) and 400 bps PSK. RTTY is sent at 50 baud Baudot using 170 Hz shift. *** UO-14 UoSAT-OSCAR 14 -------------- Name : UoSAT-OSCAR-14, NASA Catalog Number: 20437, Launched on 22-Feb-90 Orbit : Low-altitude, circular, sun-synchronous, near polar Uplink : 145.975 MHz (Manchester encoded FM) Downlink : 435.070 MHz (FSK derived from an FM receiver discriminator) The primary UO-14 beacon operates on 435.070 MHz and presently carries 9600 bit/second AX.25 FSK data. This spacecraft also carries a Packet Communications Experiment (PCE). The PCE is controlled by an 80C186 microprocessor running at 8 MHz with 4 megabytes of RAM, and uses a AX.25 (packet) communications protocol. The PCE digital transponder uses the following Mode J frequencies: Demodulators for use with UO-14 have been developed by G3RUH and K9NG. OSCAR-14 carries some of the latest OSCAR-22 images in a .GIF format, as well as other drawings and text information of interest to amateur radio operators. *** AO-16 PACSAT-OSCAR-16 --------------- NASA Catalog Number: 20439, Launched on 22-Feb-90 Orbit : Low-altitude, circular, sun-synchronous, near polar Uplinks : 145.900 MHz 145.920 MHz 145.940 MHz 145.960 MHz Downlinks : 437.051 MHz (primary, raised cosine) 437.026 MHz (secondary, BPSK) 2401.143 MHz (secondary, BPSK, 1 watt) PACSAT-OSCAR-16 is a satellite-based digital store-and-forward message system compatible with terrestrial packet communications. Uplink signals must be Manchester encoded FM (AFSK) with +/- 3 KHz deviation. The connect address is "PACSAT-1". The downlink is BPSK, NRZ-I, HDLC, and compatible with AX.25 level two protocol. The current communications data rate is 1200 bps, but can be switched to 4800 bps at a later date. Transmissions at this data rate will be straight FSK rather than Manchester-encoded so as to fit within the passband of a standard SSB voice communications receiver. *** DO-17 DOVE-OSCAR 17 ------------- NASA Catalog Number: 20440, Launched on 22-Feb-90 Orbit : Low-altitude, circular, sun-synchronous, near polar DOVE contains three downlink beacons and no active transponders: Beacon 1 : 145.824 MHz NBFM Power <= 4 watts Beacon 2 : 145.825 MHz NBFM Power <= 4 watts Beacon 3 : 2401.221 MHz 1 watt DOVE-OSCAR-17's primary objective is to provide an easily receivable satellite signal suitable for educational demonstrations involving young children. The idea for DOVE (Digital Orbiting Voice Encoder) was originated by Dr. Junior Torres DeCastro, PY2BJO with financial support from BRAMSAT. The beacons can carry AFSK AX.25 1200 bps amateur packet radio signals, compatible with standard terrestrial VHF packet radio TNCs, providing a downlink for spacecraft telemetry frames and short text messages. The beacons can also carry audio signals using the Telemetry Voice Transmitter Module. The TVTM can transmit either stored voice messages, spoken telemetry, or 1200 bps AFSK telemetry. This module contains a voice synthesizer and a digital-to-analog converter. Voice messages are digitized on the ground and sent up to the spacecraft in the form of packets, which are stored on the OBC RAM disk. The digital speech synthesizer on the spacecraft is based on a VOTRAX SC-02 synthesizer chip. At the present time, DOVE is being put through extensive tests by ground- station controllers in preparation for full commissioning of the spacecraft. If all goes well, it won't be long before the digital speech capabilities of DOVE-OSCAR-17 are tested and made a part of the regular spacecraft transmissions. *** WO-18 WEBERSAT-OSCAR 18 ----------------- NASA Catalog Number: 20441, Launched on 22-Feb-90 Orbit : Low-altitude, circular, sun-synchronous, near polar WEBERSAT has two downlink beacons and unpublished uplink frequencies: Uplink frequencies are between 144.300 MHz and 144.500 MHz. Downlink frequencies: 437.102 MHz (primary, raised cosine BPSK modulation) 437.075 MHz (secondary, BPSK modulation) Webersat's primary objective is to register, store, and downlink Earth images in a format using standard amateur satellite packet radio techniques. WO-18 also has full "PACSAT" store-and-forward capability and these resouces will be used once the primary mission of CCD image processing is fully satisfied. The CCD camera carried on WO-18 produces either a standard NTSC analog signal with color burst, or separate RGB signals with horizontal and vertical sync. Pictures are downlinked in compressed form as AX.25 packets. Image display software allows the display of these pictures. The CCD image resolution is 700 pixels x 400 lines. Since a typical picture occupies about 200k bytes of memory, downlinking at 1200 baud takes more than 20 minutes (more than one pass). WO-18 is also able to frequency modulate its downlink beacon with analog video information and in this "turbo mode", can downlink a complete image in as little as 7 seconds. Webersat also carries a 1265 MHz ATV uplink receiver, a spectrometer experiment, a particle impact detector, and a navigation magnetometer. *** LO-19 LUSAT-OSCAR 19 -------------- NASA Catalog Number: 20442, Launched on 22-Jan-90 Orbit : Low-altitude, circular, sun-synchronous, near polar Uplink frequencies: 145.840 MHz 145.860 MHz Uplinks are Manchester-encoded 3.5 KHz 145.880 MHz deviation FM. 145.900 MHz Downlink frequencies: 437.153 MHz (primary, raised cosine BPSK modulation) 437.125 MHz (secondary, BPSK modulation) 70 cm CW Beacon: 437.127 MHz (12 WPM CW Telemetry, 750 mW) LUSAT's primary objective is to provide the worldwide community of radio amateurs with a satellite-based digital store-and-forward packet radio message system in low-Earth orbit. *** FO-20 FUJI-OSCAR 20 / JAS-1b ---------------------- NASA Catalog Number: 20480, Launched on 07-Feb-90 Orbit : Low-altitude, elliptical, non-sun-synchronous Mode JA Inverting Linear Transponder: Uplink Passband: 145.900 MHz to 146.000 MHz (LSB, CW, 100 watts EIRP) Downlink Passband: 435.800 MHz to 435.900 MHz (USB, CW, 2 watts PEP) Mode JD Digital Transponder: Uplink Frequencies: #1 145.850 MHz #2 145.870 MHz Connect address is: Manchester #3 145.890 MHz 8J1JBS Encoded FM #4 145.910 MHz Downlink Frequency: 435.910 MHz (BPSK AX.25, 1 watt) CW Beacon: 435.795 MHz (20 WPM, 60 mW) FUJI-OSCAR-20 is a packet-radio store and forward communications satellite that also contains a Mode J analog (JA) transponder. It was designed to replace FO-12, which failed after several years of operation due to a poor power budget. Unlike the other packet-radio satellites currently in operation, FO-20 does not require specialized groundstation computer software for BBS access. Both uplink and downlink packets are sent as plain-ASCII text or binary data in the case of binary telemetry transmissions. The same modem hardware used for PACSAT, WEBERSAT and LUSAT can be used for FO-20. Once connected to the satellite (c 8J1JBS), the BBS responds with: FO-20/JAS1b Mailbox ver. 2.00 commands [B/F/H/M/R/U/W] Use H command for Help JAS> The spacecraft also transmits BEACON frames containing telemetry or short text messages, such as: 8J1JBS>BEACON <UI C>: JAS1b M0 91/08/17 20:04:00 Mailbox is at your service from 91/08/01 05:25:00 The JD Transmitter is available in all orbits during JD mode. 8J1JBS>BEACON <UI C>: JAS1b RA 91/08/18 20:18:58 454 484 680 689 854 839 849 834 001 726 615 000 434 486 505 477 494 512 652 000 676 758 653 676 999 643 874 278 208 000 010 111 011 000 111 100 001 111 111 000 *** AO-21 AMSAT-OSCAR 21 -------------- NASA Catalog Number: 21087, Launched on 29-Jan-90 Orbit : Low-altitude, circular Transponder #2: Uplink Passband: 435.123 to 435.043 MHz (100 watts EIRP) Downlink Passband: 145.866 to 145.946 MHz (10 watts Maximum) CW Beacon : 145.948 MHz (0.2 watts) Digital Beacon : 145.838 MHz (0.4 watts, FM) Digital Beacon : 145.800 MHz (2.0 watts, FM) G3IOR reports that he has heard the Mode B transponder of AO-21 in use over his QTH, but he notes that there are very few users. All are encouraged to monitor the downlink beacon frequencies and to use the Mode B transponders. The following is a brief summary of the AO-21 frequencies: Beacon Freq #1 145.822 MHz (CW) Beacon Freq #2 145.952 MHz (BPSK/FM) Beacon Freq #3 145.983 MHz (BPSK/SSB) Mode B Uplink 1 435.022 - 435.102 MHz (SSB,CW) Mode B Downlink 1 145.852 - 145.932 MHz (SSB,CW,Inverting) Rudak 2 Uplink 1 435.016 MHz (AFSK/FM) Rudak 2 Uplink 2 435.155 MHz (BPSK/FM) Rudak 2 Uplink 3 435.193 MHz (BPSK/FM) Rudak 2 Uplink 4 435.041 MHz (Various modes) Rudak 2 Downlink 145.983 MHz (Various modes) Beacon Freq #4 145.948 MHz (CW) Beacon Freq #5 145.838 MHz (BPSK/FM) Beacon Freq #6 145.800 MHz (BPSK/FM) Mode B Uplink 2 435.043 - 435.123 MHz (SSB,CW) Mode B Downlink 2 145.866 - 145.946 MHz (SSB,CW,Inverting) AO-21/RS14 is a multi-function satellite supporting Mode B analog transponders as well as a multitude of digital store-and-forward modes. Unfortunately, post launch electronics problems have confined operations to limited Mode B transponder #2 communications. *** RS-12/13 Radio Sputnik 12/13 ------------------- Orbit : Low-altitude, circular RS-12 Frequency Chart --------------------- Uplink Passband Downlink Passband Mode K 21.210 - 21.250 MHz 29.410 - 29.450 MHz Mode T 21.210 - 21.250 MHz 145.910 - 145.950 MHz ode A 145.910 - 145.950 MHz 29.410 - 29.450 MHz Beacon Frequencies: 29.4081 MHz, 29.4543 MHz, 145.9125 MHz, and 145.9587 MHz. Robot Uplinks: 21.1291 MHz and 145.8308 MHz RS-13 Frequency Chart --------------------- Uplink Passband Downlink Passband Mode K 21.260 - 21.300 MHz 29.460 - 29.500 MHz Mode T 21.260 - 21.300 MHz 145.960 - 146.000 MHz Mode A 145.960 - 146.000 MHz 29.460 - 29.500 MHz Beacon Frequencies: 29.4582 MHz, 29.5043 MHz, 145.8622 MHz, and 145.9083 MHz. Robot Uplinks: 21.1385 MHz and 145.8403 MHz Mode KA combines both Mode K and A uplinks into a common Mode K downlink. Mode KT uses a Mode K (or T) uplink and downlinks to both Mode K and T downlinks simultaneously. RS-12/RS-13 is very similar to RS10/RS11 and is also integrated into a parent "COSMOS" Soviet Navigation satellite. RS-12/RS-13 both support Mode A, K, T, KA and KT linear transponders, as well as several "robot" autotransponders. *** UO-22 UoSAT-5 Oscar-22 ---------------- Catalog Number: 21575 Launched: 17-Jul-91 Orbit: 775 km polar, sun-synchronous, circular low-Earth orbit UO-22 FREQUENCY PLAN: Downlink 435.120 MHz 9600 bps FSK 1200 bps AFSK (backup) 5 W or 2 W Uplink 145.900 MHz 9600 bps FSK 1200 bps AFSK (backup) Downlink 435.120 Mhz (FSK 9600) UoSAT-OSCAR-22 is the latest Amateur Satellite designed and built by the Electronic Engineering Department of the University of Surrey, in Guildford, Surrey, England. UO-22's role in the Amateur satellite service is similar to that of UO-9, UO-11 and WEBERSAT. Instead of providing a two-way communication service, it transmits experimental data and telemetry. The most exotic aspect of this spacecraft is its CCD camera. The camera design incorporates all of the lessons learned from previous UoSAT CCD experiments; it has a wide angle lens (110 degrees) which provides a field of view only slightly smaller than the satellite's footprint; images measure 1600 by 1800 kilometres, making identification of ground features much easier than on previous cameras (UO-9 and WO-18). The image consists of 578 pixels by 576 pixels, and provides ground resolution on the order of 2 km. Each pixel is 8 bits, giving a black and white image with 256 levels of grey. UO-22 broadcasts CCD images routinely using the PACSAT Broadcast Protocol. 2 Transputers in the camera module will take the image and send it over an on-board network to the main 80C186 onboard computer. The OBC puts the image into a file, with 256 bytes of header information and a PACSAT File Header. The file is then broadcast. The satellite's primary non-amateur mission is to provide store-and-forward communications for SatelLife who are using it to start a non-profit electronic mail network for health professionals. Initially, 5 African medical schools will use "HealthNet" to exchange electronic mail and receive up-to-date medical literature. HealthNet is a direct application of store-and-forward satellite communications techniques that were developed within the Amateur Service. When not serving HealthNet on non-amateur frequencies, UO-22 transmits and receives on Amateur Satellite Service channels, with AX.25 data using 9600 bit/second FSK modulation. The uplink is on 2 meters and the downlink is on 70 cm using the same frequencies as planned for UoSAT-OSCAR-15 (which has been officially abandoned). UO-22 transmits telemetry, status messages, and files, in a pattern typical of UO-14. Files are broadcast using the PACSAT Broadcast Protocol. *** SARA SARA Oscar-23 --------------- Downlink 145.995 MHz (AFSK/FM 300) *** NOAA-10 NOAA-10 ------- HRPT APT BCN --------- ------------ ------------ Freq: 1698(LSB) 137.50(VTX1) 136.77(BTX1) (STANDBY) LAUNCHED 09/17/86, MORNING DESCENDING, 1763 DAYS OPERATIONAL, AVHRR(HRPT,APT),DCS,MSU,SAR,SEM.

ROLL(Y) GYRO FAILED 09/19/89. DTR-5A & 5B HAVE MALFUNCTIONED AND ARE NOT BEING USED. DTR-1B DESIGNATED SAFESTATE DTR IS USED FOR DAILY OPS. NOAA-11 IS STILL EXPERIENCING DIFFICULTY IN THE INERTIAL MEASUREMENT UNIT (IMU). WHEN AN IMU SWITCH PERIODICALLY OCCURS, NEW GYRO SOFTWARE IS ACTIVATED. IMU SWITCHING CAN CAUSE YAW ERRORS UP TO 1 DEGREE THAT CAN REMAIN FOR 4 REVS. *** NOAA-9 NOAA-9 ------ HRPT APT BCN --------- ------------ ------------ Frequ: 1707(HSB) 137.62(VTX2) 137.77(BTX2) *** MET-3/4 MET-3/4 ------- Frequency: 137.300 mhz Meteor 3-4 (#21232) has continued to operate normally over the past month. During early morning north to south passes good quality visible mode imagery is available on 137.300 mhz. The spacecraft was heard here on 19 January 1992 during orbit number 3559 after a northbound equator crossing at 13:52 at 252 degrees west. During the evening south to north passes IR imagery is also available. Morning visible imagery is rather dark because of poor sun angle. *** MET-2/20 MET-2/20 -------- Frequency: 137.850 mhz Meteor 2-20 (#20826) has been operating normally since being switched back on in December. Midday north to south passes are available at this time. This orbital alignment gives a satisfactory sun angle for midwinter visible imagery. Excellent snow cover imagery has been obtained here after recent midwinter storms in the central United States. *** MET-2/19 MET-2/19 -------- Meteor 2-19 (#20670) remains off. *** MET-3/5 MET-3/5 ------- Meteor 3-5 remains off. *** FY-1/2 FY-1/2 ------ STATUS - JULY 16, 1991 CHINESE AUTHORITIES HAVE PROVIDED THE FOLLOWING UPDATE ON THE STATUS OF FY-1B: 1. TO LIMIT TEMPERATURE BUILD UP, THE IMAGING INSTRUMENT IS OPERATED, IN GENERAL, FOR 17 HOURS PER DAY FROM 1000Z TO 0300Z AND IS SCHEDULED OFF FROM 0300Z TO 1000Z. THIS LIMITS THE AREA IN THE WESTERN HEMISPHERE DURING WHICH TIME FY-1B WOULD BROADCAST HRPT DATA DURING DAYLIGHT. IT WAS INDICATED THAT FY-1B MAY RESUME 24 HOUR HRPT BROADCASTS IN THE FUTURE. THIS MAY NOT BE A 'RIGID' SCHEDULE SO SOME VARIATIONS MAY BE OBSERVED 2. AT THIS TIME, THERE ARE NO PLANS TO RESUME FY-1B APT BROADCASTS. FURTHER INFORMATION WILL BE PROVIDED IF THIS SITUATION CHANGES. *** +++
