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. |

PSat
2 (ParkinsonSAT) is a student satellite project which
is a two way communications transponder for relaying
remote telemetry, sensor and user data from remote environmental
experiments or other data sources back to experimenters
via a global network of internet linked volunteer ground
stations. The data transponder also includes all telemetry,
command and control for a complete cubesat. The PSat-2
is a 1.5U CubeSat.
The
unique features of PSAT-2 are the APRS transponder and
the PSK31 transponder, both of which flew on PSAT-1
and the new APRStt (TouchTone)/Voice transponder, for
which a prototype flies on the eXCITe (QIKCOM-2) satellite,
which lets everyone do APRS using any radio with DTMF
keypad, not just those with APRS radios.
The
callsigns of PSAT2 are PSAT2-1 when it is in safe-mode
with the DIGI switched off and the callsign is PSAT2
when the digi is on.

(BP-1B) was launched on July 25th
2019 by a Hyperbola-1 launch vehicle from the Jiuquan
Space Center, China into a circular orbit with a height
of 300km and an inclination of 42.7 degree. This microsatellite
was developed by the Chinese Amateur Satellite Group
(CAMSAT) in cooperation with the Beijing Institute of
Technology (BIT). CAMSAT completed the project planning,
design, build, and testing, and manages the on-orbit
operation of the satellite. BIT provided the satellite
environmental testing, launch support, and financial
support. Many students from BIT were involved in the
project, learning about satellite technology and amateur
radio. The satellite carries a CW telemetry beacon and
FM repeater that has been active since launch. Because
of the orbital apogee and the size and mass of the satellite,
the orbital life of the satellite is expected to be
only one week, up to a maximum of one month, which will
also provide with an opportunity for hams to track and
monitor satellite entering the atmosphere.
The CW telemetry
beacon us transmitting on 435.715 MHz (100mW).

OPUSAT-2
Hirogari
#47930
(1998-067SG) |
OPUSAT-2 (Osaka
Prefecture University Satellite) or Hirogari is a 1.4KG
nanosatellite that was developed by Osaka Prefecture
University. It was
developed based on the earlier OPUSAT. The
2U Cubesat was launched on board of Cygnus CRS-15 on
an Antares-230+ rocket and was thus delivered to the
ISS, from where it was deployed via the JEM airlock.
OPUSAT 2 has two
main missions:
The first mission
is to demonstrate high-speed data transmission in amateur
radio band. The satellite communication system's design
and the results of the experiment will be made public.
The second mission
is a deployment of a large folded structure. A deployable
plastic plate is stored inside the satellite, based
on Miura fold. The folding method that will be tested
in this mission takes into account the thickness of
the plate, unlike the traditional Miura fold. The satellite
will optically measure the deployment using a pair of
cameras. The team proposes applying this folding method
on space-based solar power in the future.
Hirogari uses the
following amateur radio frequencies and modes:
Downlinks:
145.900 MHz - CW beacon
145.900 MHz - AFSK 1200bd
AX.25 / GMSK 9600-13653bd AX.25
