Sounds from Amateur Radio Satellites 2006-2010

 

This section is dedicated to satellites built and operated by Radio Amateurs. Satellites built by AMSAT organizations around the world and were called AMSAT-OSCAR. Those built by Russian Hams and were mostly called Radiosputnik. In order to build and launch the satellites AMSAT needs members and friends to contribute and raise funds. If you are not yet a member of AMSAT please consider to join us and to support the activities. You can find several links to AMSAT on my links page.

Falconsat-3
#30776
(2007-006E)

FalconSat-3 is a 57kg satellite developed by U.S. Air Force Academy in Colorado, United States. It was launched on an Atlas-5(401) rocket from Cape Canaveral into a circular orbit with a height of 560km and an inclination of 35 degrees. The three primary experiments are
-  Flat Plasma Spectrometer (FLAPS), a planar electrostatic analyzer used to measure ion spectra differential in energy
- Plasma Local Anomalous Noise Environment (PLANE) experiment, a bifurcated retarding potential analyzer capable of distinguishing between ambient and spacecraft-induced turbulence
- Micro-Propulsion Attitude Control System (MPACS), consisting of a set of Teflon-fueled pulsed plasma thrusters used to stabilize satellite attitude.
Falconsat-3 is switched on during most day and evening passes over the USAFA with a very strong downlink on UHF. It is running the pacsat file system so anyone with WiSP can copy telemetry.

After concluding its primary missions Falconsat-3 was transferred to full amateur radio service in late summer 2017. It operates as a store-and-forward system. The 9k6 bps uplink is at 145.840 MHz, the 9k6 bps downlink is at 435.103 MHz, It may support also 38k4 or 76k8 bps in the future.

AGGIESAT-2
#35690
(2009-038B)

On July 30th 2009 the DRAGONSAT-2 (Dual RF Astrodynamic GPS Orbital Navigator Satellite) project was released from Space Shuttle Endeveaur (STS-127). It consists of 2 sister satellites BEVO-1 and AGGIESAT-2. AGGIESAT´s downlink frequency is 436.250 MHz and it uses a proprietary modem protocol as the main radio is a COTS data modem. It appears that the only way to decipher the code is to have a model MHX425 that can speak the proprietary language. The radio data rate is actually at 19200 bps.

July 30th 2009

The audio file of AGGIESAT-2 was recorded by Mike DK3WN on July 30th 2009 at 16:04 UTC during the 2nd orbit of AGGIESAT-2.

 

BEVO-1
#35690
(2009-038B)

BEVO-1 was deployed together with its sister satellite AGGIESAT-2 from Space Shuttle mission 127 on July 30th 2009 at 12:34:50 UTC as part of the DRAGONSAT program. It is a picosat mission of the University of Texas to test a GPS unit designed and built by NASA. Texas A&M and the University of Texas were required to build 5" cubesat spacecraft buses and support systems for the GPS units.
Beacon Mode
Downlink Frequency: 437.325 MHz
Modulation: FM, 200mW, Morse Code, ~20 WPM
Data Mode
Downlink Frequency: 437.325 MHz
Modulation: FSK, 1W, 9600 baud, AX.25 (default) or FM, 1W, Bell 202, AX.25.

July 30th 2009

Status as of August 5th 2009: Still no signals from BEVO1, although beacon packets were heard from AGGIESAT2. The current theory on the state of the satellites is that only partial separation occurred. The inhibit switches keeping the satellites powered off have been closed, allowing the satellites to boot up. However, it is likely that the antennas did not deploy correctly, leaving the antennas disconnected from their respective transmitters. AGGIESAT2 transmits with 1W of power so it is easier to hear, while BEVO1 only transmits with 200mW during beacon mode.

Unfortunately the 2 satellites did not separate after they were released from the space shuttle you will find only one single set of Keplerian elements referred to as "DRAGONSAT". On the left you can also see 2 pictures where AGGIESAT-2 (top) and BEVO-1 (bottom) are shown still attached to each other after launch.

(2009-038E)

On July 30th 2009 the ANDE-2 project was released from Space Shuttle Endeveaur (STS-127). It consists of 2 satellites called Castor and Pollux.
Pollux-1 transmits every 33 seconds a telemetry packet on 145.825 MHz in FM/AFSK using 1200bd with F.25 (FEC) on top of AX.25. It also has the possibility to transmit 9600bd packet radio signals and test GMSK modulation. Pollux´s transmit frequency is about 1.5 to 2 khz higher than Castor´s. Furthermore the signal of Pollux is stronger than Castor´s signal in spite of the fact that they should use the same transmit power of up to 1W. Enclosed audiofile which contains signals from Castor and Pollux was recorded by Mike DK3WN during orbit no.1 on July 30
th 2009 at 17:44 UTC.
