Catalog number: 23439
Launch Date: December 26, 1994
Uplink 145.858 to 145.898 MHz CW/USB
Downlink 29.354 to 29.394 MHz CW/USB
Beacon 29.352 MHz (intermittent)
SSB meeting frequency 29.380 MHz (unofficial)

Dave WB6LLO, reports the following for RS-15[04022004]:
I've confirmed that the signals I'm hearing from RS-15 are coming from the satellite, and not some other source by checking repeated AOS/LOS's. I have heard nothing from the transponder uplinking 100 watts to a 10 dB antenna on cw. My receive antenna is an inverted "V", but if the transponder was active I should have heard something. I've had no response from a previous request to other users. The on/off tone varies from ~12/min. to 22/min. in the dozen or so passes I've observed. The start/cessation of the tone does not appear to be a function of a keying circuit, but rather as though power was being intermittently applied to an oscillator.

Howard K6IA, reports [04022004]:
I also copied a very loud on and off tone at 29.352 on the 0115 UTC pass of RS-15. I could not hear a signal coming back through transponder, uplinking 100 watts CW into a 11 dBdC yagi. I can work AO-7 mode A with 25 watts or less. I wish I could of heard something coming back. The beacon was a lot stronger then I've heard on AO-7 when it's in mode A.

I have now processed another batch of reports, those submitted after 0500 2 March and before approx 0530 11 March 04. The reports are available at and QSLs can be downloaded at

This from Clive, G3CWV [03302004]:
Just to remind anyone wishing to send a last minute QSL report to AMSAT-UK. The VHF beacon is now transmitting ASCII telemetry on 145.826 MHz. It switched ON sometime between 07:15 and 13:30 UTC, today, 30 March, after ten days of silence. Telemetry nominal.

The S-band beacon 2401.5 MHz is also ON, transmitting a weak continuous carrier.

Downlink 435.812 MHz SSB, 1200 Baud PSK
Broadcast callsign: ITMSAT-11
Status: No uplinks currently

This from Alberto E. Zagni - I2KBD on November 26,2003:

I can confirm that IO-26 is still in Safe Mode (MBL telemetry). We have some problems to uplink the full IHT software, probably due to an unfavourable attitude of the spacecraft. Until the IHT (high level code) is reloaded, NO digipeat will be possible, since it is part of the IHT multitasking code.

All the best
Alberto E. Zagni - I2KBD

NO-45 Sapphire

Catalog number: 26932
Launch Date: September 30, 2001
Downlink 437.095 MHz 1200 baud AX.25 AFSK
Uplink 145.945 MHz UI digipeater
Status: Operational

The NO-45 digipeater remains on. User are requested NOT to use the Bulletin Board. When the Bulletin Board is used it effectively "locks out" ground access to the spacecraft CPU.

Everyone is welcome to use the digipeating/APRS features of Sapphire, callsign KE6QMD, as per the user service agreement located at

There will be occasional dropouts caused by the CW beacon, and users are advised to expect extra packet chatter during West Coast (USA) passes, as some schools are using Sapphire for operations training.

Student built Sapphire was launched through the U.S. Naval Academy Satellite program. Its primary missions are sensor experiments, a camera, and voice synthesizer. For more information, visit the Sapphire web site at

Catalog number: 25509
Downlink 437.910 MHz FM 9600 Baud FSK
Launched October 24, 1998 by a Delta 2 rocket from Cape Canaveral in Florida

The satellite is not currently available for uplink transmissions and image and transponder recovery efforts have been unsuccessful.

SEDSAT-1 signifies Students for the Exploration and Development of Space (satellite number one).

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.

Catalog number: 25520
Uplink/downlink frequency (listed on the PanSat web site) 436.500 MHz
Launched October 30, 1998 by the Shuttle Discovery
Status: Telemetry downloads only.

The Naval Postgraduate School developed PanSat. At the time of launch, PanSat spread-spectrum digital transponders were to be available to amateur radio operators along with software to utilize this technology.

The satellite is still operating, however, the spread spectrum packet radio portion never took place. The spacecraft is now beyond it's initial 2-year mission life, but telemetry records are still being downloaded.

PanSat was the featured cover article in the July/August 1999 issue of the AMSAT-NA Journal (written by KD6DRA and N7HPR).

AO-49 (SAFIR-M) is a German amateur radio payload onboard the small German scientific satellite "RUBIN-2".

AO-49 was built by the German amateur radio association "AATiS e.V." (German acronym for "Arbeitskreis Amateurfunk und Telekommunikation in der Schule", which means: 'working group for amateur radio and telecommunications in schools'). AO-49 is designed as a "store and broadcast" system for APRS based messages, dedicated for the use of schools in combination with the existing WX-Net and planned buoy experiments in Germany.

No transmissions detected since the 1st of February 2003! It appears AO-49 is not properly aligned to illuminate the solar panels. This should end soon. Due to its orbit, AO-49 will be in a phase without eclipses until 13Feb03.

Martin DG8UAU has written a small software program "SAFIR-M Decoder" to allow decoding of the received DATA0 frames. It is available at in the section Aktuelles.

Details on AO-49 (SAFIR-M) can be found at
Information about AATiS e.V. is available at
