SB SAT @ AMSAT $ANS-124 01 Seven! Count 'Em Seven! CubeSats Delivered to Orbit

AMSAT News Service Bulletin 124 01

From AMSAT HQ SILVER SPRING, MD May 4, 2008 To All RADIO AMATEURS BID: $ANS-124 01

The April 28, 2008 launch of 10 satellites aboard the Indian Space Research Organization's (ISRO) Polar Satellite Launch Vehicle-9 (PSLV-9) rocket included 7 amateur radio cubesat, and 3 commercial/ scientific satellites Watch for late breaking operational messages via the amsat-bb and detailed information on each of the satellite's respective web pages

The payload included: Cute-1 7 Tokyo Institute of Technology, Japan SEEDS Nihon University, Japan Delfi-C3 Technical University of Delft, Netherlands AAUSat-II Aalborg University Cubesat, Denmark COMPASS-1 Fachhochschule Aachen, Germany CanX-2 University of Toronto, Canada CanX-6 University of Toronto, Canada Cartosat 2A Indian Space Research Organization (non-amateur radio) IMS 1 Indian Space Research Organization (non-amateur radio) Rubin 8-AIS OHB-System, Germany (non-amateur radio)

An excellent source of information for each of these satellites can be found at: http://space skyrocket de/index_frame htm (scroll down to the April 28 data) Also see Ralph W0RPK Cubesat Webpage at: http://showcase netins net/web/wallio/CubeSat htm

Wouter, PE4WJ provided the following status of Delfi-C3:

Telemetry indicates that all solar panels and antennas have deployed properly and indicates nominal values for all housekeeping values
Payload data has started to stream in, enabling the team to generate IV curves of the Thin Film Solar Cell experiment (RASCAL users can view the IV curves by clicking Options-->show IV curves )
The spacecraft is operating in science mode, we have had one orbit in emergency mode, which was most probably due to a databus issue
Amateur radio operators have sent over 40000 frames of data using RASCAL, the Delfi-C3 telemetry capture software
The spacecraft has decided to consistently use the backup radio on 145 930 MHz for its telemetry downlink The primary radio on 145 870 MHz may be switched on by the groundstation so monitor both frequencies
We have successfully switched the spacecraft to its primary radio on 145 870MHz temporarily, after this switch, the satellite came back on the 145 930MHz downlink Telemetry indicated that the primary radio on 145 870MHz is healthy and working fine so that is good news Note that the satellite will normally transmit on 145 930MHz for the time being, unless we command her to go to 145 870MHz
The team is working on the issue with the downlink TX switching off later into the sunlit side of the orbit, which is the reason why Delfi-C3 has not been heard on some passes It may switch off when the computer does not receive data but the transmitter itself is OK

Hiroki Ashida at the Tokyo Institute of Technology reported on the status of their Cute-1 7 + APD II satellite The team is monitoring an anomaly where the telemetry received via FM packet shows very low battery voltage while the CW telemetry reports a nominal reading If this low voltage condition exists the satellite may be in danger Further testing in the lab has duplicated this anomaly and the team has confirmed that the batteries are in good shape at this time

The Cute-1 7 team requests telemetry information from radio amateurs around the world The satellite transmits its beacon at 437 275 MHz using CW Morse Code The telemetry data in the beacon includes the battery voltage Details are explained on their web-page: http://lss mes titech ac jp/ssp/cute1 7/cwtelemetry_e html The packet telemetry is only enabled when the satellite is over Japan

Masahiko Yamazaki,JQ1YGV at Nihon University reported that the SEEDS satellite is currently overcharging so the team has enabled the FM mode to transmit the DigiTalker and SSTV pictures on 437 485 MHz See: http://cubesat aero cst nihon-u ac jp/index html

The CanX team reported their spacecraft were doing well, "So far healthy telemetry from both At some point CanX-2 was generating some 1 8 A and CanX-6 was at 1 4 A Good temperature on both CanX-2 propulsion system is holding pressure We are continuing with commissioning Both satellites are currently transmitting on the Space Research 2 2 GHz downlink The UHF transmitter on CanX-2 would only be active over the ground station in Toronto, Canada

Signal reports of the cubesats have been received from around the world Here is a brief example captured from the amsat-bb

Just heard great signals of Delfic3 on 145 930 - Rob PE1ITR

Received good signals from DelfiC3 tonight in IO91TK 15km west of London Nice to hear another satellite on 2m Just love that low path loss! Well done Delft University of Technology - David G0MRF

Very strong signal from Delfi telemetry transmitter Good work and congratulations to the Delfi team! - Jean-Pierre VE2AHD

Delfi-C3 received in Belgium during the third pass 194 packets received, decoded with RASCAL and sent to the command station Signals were loud and decodable during 90 % of the pass Congratulations to the team Long life to Delfi-C3 - Claude ON5QI

Just had my one shot for the morning and got an excellent signal, with AOS and LOS within seconds of predicted The RASCAL program is slick, and nicely accessed the servers to upload the data
- Alan WA4SCA

Both the CUTE1 7 (437 275) and the SEEDS (437 485) CW signals were monitored in Brno JN85HF - Mirek OK2AQK

Using the latest kepler sets, automatic doppler correction, TS2000X, 2x8 elements beam with no pre-amp picked up the CUTE-1 7 signal beautifully all the way from AOS to LOS less than one degree elevation from a 100mW transmitter in space Fantastic satellite! - Henk, PA3GUO

I copied SEEDS this evening at 44 degrees el in Honolulu 73 to all and congratulations to the Nihon University Cubesat Team! - Robert NH7WN

I have updated my web site to include SEEDS SSTV See http://www turlington supanet com - Robert G8ATE

Heard SEEDS digi-talker and SSTV on 2008-05-03 - Edward BX1AD

I have just copied Cute-1 7 over here in the UK (Wales - IO81EM) using a Kenwood THD-7 and just its helical antenna - Ken GW1FKY

The members of AMSAT-India and the Indian Ham fraternity congratulate ISRO for the successful 10 pack satellite launch via the PSLV C9 his morning We would also congratulate the DELFI team, CUTE team and the SEEDS team for their amateur radio satellites which are now placed in orbit VU2POP Secy AMSAT-India

SB SAT @ AMSAT $ANS-124 02 AO-16 Down and Recovered

AMSAT News Service Bulletin 124 02

From AMSAT HQ SILVER SPRING, MD May 4, 2008 To All RADIO AMATEURS BID: $ANS-124 02

The AO-16 Command Team investigated reports this week that the satellite had gone silent The team is aware of the anomaly and there is no cause for alarm Control Operator, Mark, N8MH said, "Over the last month AO-16 has gone from full illumination (0 minutes of eclipse) to over 250 minutes of eclipse Since the bird has no fancy housekeeping code running, a reasonable explan- ation is that the battery voltage dropped low enough to put the bird into a protected (and silent) mode "

Mark was able to command AO-16 ON during a pass over the USA The satellite resumed operating in its 1200 BPSK digital MBL telemetry mode on the 437 026 MHz transmitter After further testing, Mark reported, "A quick look at the telemetry suggests that AO-16 is doing fine The current transmitter output power is about 1 5 Watts AO-16 is again configured for voice mode and is open for normal operation "

AO-16 has occasionally turned off on subsequent long eclipse periods Mark explained, "At about 2043 utc on 2 May 2008 I commanded AO-16 back ON again Apparently the increasing eclipse periods require another reduction in the transmitter output power AO-16 is now back and operational in voice repeater mode, with a slightly reduced output It is reporting around 1 2 watts output, so it was still quite loud "

The increasing eclipse periods are too long to sustain operations at the previous transmitter output setting The sustainable power budget is being managed empirically by Mark, with "best guess" settings using the satellite's telemetry for feedback on its performance

When AO-16 is silent the batteries continue to charge with minimal current being drawn to sustain the vital functions of the satellite (CPU) Thus, it is in a safe resting state at the moment, and the batteries continue to charge when in sunlight Thanks to a brilliance in design, construction, and coding, the bird is hardy and excellent at self-preservation

AO-16 Uplink: 145 920 MHz FM AO-16 Downlink: 437 0260 MHz DSB (LSB and USB)

After recovery of AO-16 on May 3, the current plans are to leave the satellite in the digital MBL mode for a few days so as to collect telemetry for review You can hear the satellite "humming" in its 1200 BPSK mode

Interested listeners of AO-16 can help by copying any telemetry captured via the Warbler sound card demodulator This software is from the same folks that brought you the RASCAL software for Delfi-C3 A file called "warbler kss" is produced when packets are decoded These "warbler kss" files can be sent to N8MH for analysis Please include your QTH (gridsquare) and the time the telemetry was captured

Telemetry from AO-16 in the MBL mode is random and infrequent It's possible to hear no telemetry during an entire pass Please do not transmit to AO-16 until further notice

Users of AO-16 are encouraged to report any aberrant operations by either posting to the AMSAT-BB or by emailing the command team at n8mh AT amsat org "Aberrant operations" might include the following: complete loss of signal from the spacecraft or significant change in the transmitter frequency
