Nya Cubesats från ISS 2018-05-11

Den 11 maj 2018 släpptes tre nya Cubesats ut från ISS med amatörradio ombord. Alla dessa tre har rapporterats bla. via DK3WN. Frekvenser enligt följande:

1KUNS-PF (Kenya)- NORAD CAT ID 43466 (a 3U cubesat with a 1200 bps or 9600
bps telemetry beacon at 437.300 MHz)

UBAKUSAT (Turkey)- NORAD CAT ID 43467 (a 3U cubesat with a CW beacon at
437.225 MHz, a telemetry beacon at 435.325 MHZ, and a linear transponder
with a 435.200 – 435.250 MHz downlink / 145.940 – 145.990 MHz uplink)

Irazu (Costa Rica) – NORAD CAT ID 43468 (a 1U cubesat with a 9600 bps
telemetry beacon at 436.500 MHz)

Äldre keplerelement

Behöver du äldre keplerelement? AMSAT-NA har ett arkiv för detta. Se nedan:

25 Year Archive of Keplerian Elements Now on AMSAT Web Site

AMSAT Orbital Elements Manager Ray Hoad, WA5QGD    has made his archive
of orbital elements for active amateur satellites back to October 1993.
Joe Fitzgerald, KM1P has posted this on the AMSAT web site at:
http://www.amsat.org/tle/historical/   Joe commented, “Thanks for all
those bulletins, Ray. That represents a lot of work over 25 years!”

AMSAT-SM på ESA Radiomässa / SSA årsmöte 2018

AMSAT-SM besökte årets Radiomässa i Eskilstuna tillika SSA årsmöte. Runt 1000 besökare kom denna dag. Tack till alla som stannade vid vår monter och kollade på SSTV-mottagning från ISS, SDR-programvara, en modell av Funcube (AO-73) i skala 1:1 mm. Hoppas att någon blev intresserad att prova på amatörradio via satellit.

SSTV från ISS april 2018

Just nu pågår en serie sändningar med SSTV från ISS. Mycket stark signal på 145.800 MHz FM. Här några bilder jag tog emot lördagen 14/4 2018:

AO-92 är nu öppen för amatörradiobruk

Nu är AO-92 öppen för amatörradiobruk, eller som det kallas på satellitspråk “Commissioned”. Nedan kan du läsa det officiella meddelandet inkl. en bra frekvensguide:

On the 03:25 UTC pass on January 26, 2018, AMSAT Vice President –
Engineering Jerry Buxton, N0JY, announced that AO-92 had been
commissioned and formally turned the satellite over to AMSAT
Operations. AMSAT Vice President – Operations Drew Glasbrenner, KO4MA,
then declared that AO-92 was now open for amateur use.

Initially, the U/v FM transponder will be open continuously for a
period of one week. After the first week, operations will be scheduled
between the U/v FM transponder, L-Band Downshifter, Virginia Tech
Camera, and the University of Iowa’s High Energy Radiation CubeSat
Instrument (HERCI).

Schedule updates will appear in the AMSAT News Service Weekly
Bulletins and will also be posted to the AMSAT-BB, AMSAT’s Twitter
account (@AMSAT), the AMSAT North America Facebook group, and the
AMSAT website at https://www.amsat.org/satellite-schedules/

AO-92 was launched on the PSLV-C40 mission from Satish Dhawan Space
Centre in Sriharikota, India on January 12, 2018. For the past two
weeks, the AMSAT Engineering and Operations teams have been testing
the various modes and experiments on board. Testing has shown that
both the U/v FM transponder and L-Band Downshifter work very well. The
Virginia Tech camera has returned stunning photos and data from HERCI
has been successfully downlinked.

AMSAT thanks the 178 stations worldwide that have used FoxTelem to
collect telemetry and experiment data from AO-92 during the
commissioning process. The collection of this data is crucial to the
missions of AMSAT’s Fox-1 satellites. Please continue to collect data
from AO-85, AO-91, and AO-92.

RADIO PROGRAMMING CHART
Fox-1D Doppler Shift Correction

Memory 1 (AOS) – TX 435.340 MHz (67.0 Hz Tone), RX 145.880 MHz
Memory 2 (Rise) – TX 435.345 MHz (67.0 Hz Tone), RX 145.880 MHz
Memory 3 (TCA) – TX 435.350 MHz (67.0 Hz Tone), RX 145.880 MHz
Memory 4 (Descend) – TX 435.355 MHz (67.0 Hz Tone), RX 145.880 MHz
Memory 5 (LOS) – TX 435.360 MHz (67.0 Hz Tone), RX 145.880 MHz

The L-band experiment will use 1267.350 MHz uplink with 145.880 MHz
downlink. UHF and L-band uplink operation are set by the command
stations; the operating schedule will be posted.

Executive Vice President Paul Stoetzer, N8HM for the above information]

AO-92 L-band testad

Det finns en del ny information om arbetet med AO-92 och L-bandstesterna (se även videon nedan).

“The AMSAT Engineering and Operations teams have been hard at work testing the various modes and experiments aboard AO-92 since its launch on January 12th. Since the last update, testing has concentrated on the University of Iowa’s High Energy CubeSat Radiation Instrument (HERCI) experiment and the AMSAT L-Band Downshifter.”
