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.

Downlink Frequency: 437.325 MHz
Modulation:
FSK, 1W, 9600 baud, AX.25 (default) or FM, 1W, Bell

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. |

Castor
#35694
(2009-038F) |
On July
30th 2009 the ANDE-2 (Atmospheric
Neutral Density Experiment) project was released from
Space Shuttle Endeveaur (STS-127). It consists of 2
spherical satellites called Castor and Pollux fitted
with retro-reflectors for satellite laser ranging (SLR).
The constant and well-determined cross section and surface
properties of the ANDE spacecrafts provide an ideal
set of objects for monitoring atmospheric drag and the
calibration of space surveillance network (SSN) assets
both radar and optical.
Castor-1 is a 49cm diameter
aluminum sphere with a mass of 63 kg. It tramsmits telemetry
on 145.825 MHz using the callsign KD4HBO-1. Enclosed

(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 30th
