MIR SPACE STATION
145.985 MHz Simplex (FM) Voice and SSTV (Robot 36 Mode)
AMSAT's Bruce Paige, KK5DO, reported that two cosmonauts
--Sergei Zalyotin and Alexandr Kaleri-- have arrived on the Russian Mir
space station after an April 4, 2000 launch from the Baikonur
Cosmodrome and the successful docking with Mir.
Ham radio activity aboard the Mir space station is apparently back on
line -- currently in limited fashion. No ham radio activity has been
reported from the orbiter during the last several weeks.
Stay tuned to ANS for further details.

AMRAD AO-27
Uplink 145.850 MHz FM
Downlink 436.795 MHz FM
Operational, mode J.
An AO-27 question-and-answer page is available on the AMSAT-NA
web site. Ray, W2RS, recently updated the information. The URL is:
http://www.amsat.org/amsat/intro/ao27faq.html
AO-27 uses a method called Timed Eclipse Power Regulation (TEPR)
to regulate the on-board batteries. In simple terms, TEPR times how
long the satellite has been in an eclipse (or in the sun) and decides
what subsystems to turn on or off. The AO-27 pages on the AMSAT-NA
web site include an explanation of AO-27 operations (at):
http://www.amsat.org/amsat/sats/n7hpr/ao27.html
Chuck, KM4NZ, reset the TEPR states on AO-27 (on 05/18/2000).
TEPR 4 is 42 - TEPR 5 is 78

digital signals. "Sunsat will now also offer digital services," confirmed
Johann, ZR1CBC, of the SunSat command team.
The SunSat package includes 1200 and 9600 baud digital
store-and-forward capability and a voice 'parrot' repeater system
that will be used primarily for educational demonstrations.
The satellite has two VHF and two UHF transmit-receive systems.

Operational. FO-20 is in mode JA continuously.
JAS-1b (FO-20) was launched in February 1990.
Takushi, JO2OXL, reports that the JARL FO-20 Ground Station
operators believe that with the inability to (now) determine the
satellite battery status (through the loss of the beacon), it is
possible that FO-20 is in its final phases. Operation will continue
as long as possible.
[ANS thanks Kazu Sakamoto, JJ1WTK, for the FO-20 status reports]

addressing analog, digital and digi-talker modes. To obtain a copy
e-mail Mike at: kf4fdj@amsat.org
Kazu, JJ1WTK, reports the FO-29 operational schedule
(announced by the JARL) is as follows:

program. The software will automatically analyze all digital
telemetry from the satellite such as current, voltage and temperature.

Downlink 435.175 MHz FM
Operational.
Jim, AA7KC, reports KO-23 is (again) operational, with 86% data
downlink efficiency on 5/26/00 at 04:38 UTC. KyungHee Kim,
HL0ENJ, reports (from the KO-23 control team) that part of the
problem with non-operation has been the power budget aboard
the satellite. Currently, KO-23 is also in a maximum eclipse period.

Jim, KI0BK, reports he is a new user of KO-25 as he recently
"successfully accessed KO-25 and downloaded about 56k of data."
[ANS thanks Jim Weisenberger, AA7KC, for KO-25 status information]
UOSAT UO-22
Uplink 145.900 or 145.975 MHz FM 9600 baud FSK
Downlink 435.120 MHz FM
Operational.
Chris Jackson, G7UPN, reported to ANS last March that UO-22 was in
full sunlight and the temperatures had increased considerably.
Controllers (at that time) turned the satellite upside down to point the
critical systems to cold space. At the time of the last report only the
145.900 MHz receiver was usable for communications. No further
information has been received from the UO-22 ground control stations.
More information on the satellite is available at the following URL:

OSCAR-11
Downlink 145.825 MHz FM, 1200 baud AFSK
Mode-S Beacon 2401.500 MHz
Operational.
OSCAR-11 celebrated its sixteenth birthday in space on March 1, 2000.
The operating schedule is as follows:
ASCII status (210 seconds)
ASCII bulletin (60 seconds)
BINARY SEU (30 seconds)
ASCII TLM (90 seconds)
ASCII WOD (120 seconds)
ASCII bulletin (60 seconds)
BINARY ENG (30 seconds)
The ASCII bulletin is currently a static message, detailing modes and
frequencies of all active amateur radio satellites.
Users should note that the date in the hardware generated ASCII
telemetry is now advanced by 3 days and the other dates (which
are generated by software) are advanced by 1 day. Ground control
may be able to correct the software generated dates, but not the
hardware generated date.

Russ, WJ9F, reported last March that ground stations were running
memory test software on the satellite. In addition to the memory testing,
ANS received information that the spacecraft spin rate around the
vertical (Z) axis created a less than ideal condition for battery charging.
No recent information about these situations has been received by ANS.
Normally, the S-band transmitter is off.

ProcMail V2.00G has been released by G7UPN. This software permits
the processing of image files from TO-31. It has been posted to the
AMSAT-NA FTP site at the following URL:

Many of the high-resolution color images transmitted by TMSAT are
compressed using a UoSAT compression format. This format is
supported by the VK5HI CCD display program.

UoSAT-12 was successfully launched on April 21, 1999 from the
Russian Baikonur Cosmodrome. UO-36 carries a number of imaging
payloads, digital store-and-forward communications and mode L/S
transponders.
NASA recently demonstrated the ability to use standard Internet
protocols to communicate with an orbiting spacecraft (just like any node
on the Internet) - via UO-36. NASA has been developing this project by
working with the commercial payload on UoSAT-12.
The BBS is open, although uploading (and the downlink) may be
disabled at times.

TECHSAT-1B GO-32
Downlink 435.225 MHz using HDLC telemetry
Efforts were reported to be underway to bring GO-32 on line,
however no additional information has been received by ANS
(the last report was dated November 1999).
The TechSat-1B micro-satellite was successfully launched from the
Russian Baikonur Cosmodrome on July 10, 1998.
Last reported, the satellite does not have a continuos beacon, but does
transmit a 9600-baud burst every 30 seconds (for a continuous 3
seconds in length), on 435.225 MHz.
The TechSat team has constructed a home page about TechSat.

PANSAT PO-34
Uplink/downlink frequencies have never been released.
The satellite is not currently available for general uplink transmissions.
PanSat, developed by the Naval Postgraduate School, was launched
from the shuttle Discovery (during STS-95) on October 29, 1998.
At the time of launch, PanSat spread-spectrum digital transponders
were promised to be available to Amateur Radio operators along with
software to utilize this technology. To date, this has not happened.
For more information, visit the official PanSat web site at:

DOVE DO-17
Downlink 145.825 MHz FM 1200 baud AFSK
2401.220 MHz
Non-operational.
DOVE stopped transmitting in March 1998. The 145.825 MHz and
2401.220 MHz downlinks are off the air and the satellite has not
responded to ground station control. No additional information is
available at this time.
WEBERSAT WO-18
Downlink 437.104 MHz SSB 1200 baud PSK AX.25
Non-operational.
WO-18 was last reported to be in MBL mode after a software crash.
No additional information is available at this time.
SEDSAT-1 SO-33
Downlink 437.910 MHz FM 9600 baud FSK
The satellite is not currently available for uplink transmissions and
image and transponder recovery efforts have been unsuccessful.
SedSat-1, signifying Students for the Exploration and Development of
Space Satellite number one, was successfully launched and placed in
orbit on Saturday, October 24, 1998.
SedSat-1 has downlinked months worth of telemetry data on the
performance of its electrical power system parameters. The Nickel
Metal Hydride batteries on the spacecraft were experimental and
experienced some abuse due to a power negative situation. This
information has provided NASA with useful information. With the
exception of the imaging system and the use of the transponders,
SedSat-1 has been judged a success.
