AO-95 receiver anomaly – Commissioning Status

Not so good news from ANS:

Following the launch of Fox-1Cliff/AO-95 AMSAT Engineering began the
commissioning process, with the help of AMSAT Operations, on Tuesday
December 4.  Satellite telemetry indicates that the bird is healthy,
and I thank all of the stations who have captured and relayed the
telemetry that enabled us to monitor and determine the health of the
various systems on board.  Fox-1Cliff required an extended period
monitoring battery and power levels due to the anomaly and fix that
was applied back in February of 2016 during environmental testing,
and the result of that is positive.

However, during the next steps of commissioning we discovered an
anomaly with her receive capability.  After a few days of tests,
analysis, and discussion, it appears that Fox-1Cliff/AO-95 will not
be commissioned as our fourth Fox-1 amateur radio satellite.

AMSAT Engineering will continue to evaluate and test Fox-1Cliff/AO-
95 for solutions to the anomaly and your continued help in providing
telemetry is appreciated so that we can have data throughout her
daily orbits rather than limited data over our U.S. stations.  The
data, analysis, and testing could lead to a positive solution but at
the very least will be important to AMSAT's satellite programs in
providing information that would help us and others, as we do freely
share our successes and failures, to avoid similar situations with
future missions.

I would like to thank all of the AMSAT Fox Engineering volunteers
who made Fox-1Cliff possible and continue to build our new
satellites, becoming even better as we move forward.

I will provide more information on the anomaly and any determination
we make regarding the possible cause or causes as well as information
on the possibility of recovery, over time.  Please be patient
regarding that.  Many of you have probably built a project and had to
troubleshoot it on your bench, we are in a troubleshooting situation
here with the additional challenge of being 600 km away from our
bench.

Nya Oscar AO-95 VO-96 JO-97

I och med den senaste uppskjutningen med bla. Fox-1Cliff har vi fått tre nya Oscar-satelliter:

  • Fox-1Cliff heter nu även AMSAT-OSCAR 95 (AO-95)
  • ExseedSat heter nu även VUsat-OSCAR 96 (VO-96)
  • JY1Sat heter nu Jordan-OSCAR 97 (JO-97)

Vilken satellit kommer få Oscar nummer 100?

Es’hail-2/P4A uppdaterad information

Nu finns lite mera information om Es’hail-2/P4A. Just nu befinner sig satelliten i en temporär “slot” på ~24°E. Efter en del tester kommer satelliten flyttas till sin riktiga plats på 26°E. Just nu pågår en kommersiell testfas och först efter att den är klar kommer amatörradiotranspondern att slås på.

Senaste kepler är följande, om nu någon behöver mata in dessa manuellt:

ES’HAIL 2
1 43700U 18090A 18331.74832885 .00000138 00000-0 00000+0 0 9994
2 43700 0.0937 247.5840 0001194 359.8609 112.5666 1.00272646 252

Här kommer hela informationen från Peter Guelzow, DB2OS, AMSAT-DL:


Es’hail-2 with the P4A transponder is currently in a temporary GEO
slot at ~24°E. After testing the satellite will be moved to the
location planned to be at 26°E.

Peter Guelzow, DB2OS, explained the current testing and commis-
sioning procedures, “During the next 1-2 month Es’hail-2 will
undergo fine tuning and extensive In-Orbit-Testing (IOT). The
current orbital position is selected to not interfere with other
GEO satellites nearby. Once testing is finished, the satellite
will slowly be drifting to and stationed at the final position.”

The checkout and inauguration of the both AMSAT transponders will
be performed after the IOT phase is finished as explained at:
https://amsat-dl.org/p4a-positionining-and-iot

Peter reported several “hunters” have already spotted the Engineer-
ing beacon from Es’hail-2, so obviously everything looks good and
is going according to plan.

Stay tuned for latest news on https://amsat-dl.org and  the official
Es’hail-2 / P4-A discussion forum on:
https://forum.amsat-dl.org/index.php?board/3-es-hail-2-amsat-phase-4-a/

The AMSAT Phase 4-A transponder on Es’hail-2 is a joint project by
the Qatar Satellite Company (Es’hailSat), the Qatar Amateur Radio
Society (QARS) and AMSAT Deutschland (AMSAT-DL).

Recent Keplerian Elements for Es’hail-2 are:

Pedro, LU7ABF says that the tracking site on the AMSAT-Argentina web
provides visualization of the current satellite location and footprint:

Amateur Radio Contest for Receiving PW-Sat2 Telemetry

PW-Sat2, the second Polish student satellite, also launched on the
SpaceX Falcon 9 SSO-A flight with AMSAT Fox-1Cliff, is a student pro-
ject with the goal to test a new deorbit sail. A team formed of over
30 students from many different faculties of Warsaw University of
Technology started working on a new satellite in 2013. For more
information visit:

https://github.com/PW-Sat2/HAMRadio/wiki

Amateur radio operators are invited to take part in a multi-faceted
contest. How to take part in the contests? It’s easy! Register on the
website: https://radio.pw-sat.pl/ – then – use the application for
HAM radio, to receive, decode and upload PW-Sat2 frames to our cloud
based service. Just after completing of the PW-Sat2 satellite mission,
the team will announce the winners and send prizes!

On the ham radio contest web page https://pw-sat.pl/en/ham-contest/
you’ll find several categories to participate:

+ QSL cards – for a correctly received and decoded frame
+ The first received and uploaded frame – First come, first served!
+ The last received and uploaded frame – During the deorbit sail
deployment sequence!
+ The largest number of uploaded frames

PW-Sat2 will transmit on 435.275 MHz using 1k2-9k6 BPSK AX25.

Y1SAT Dashboard

Från FUNcube websida kommer information om kommande JY1Sat och ESOE. Bla så finns nu data warehouse, dvs. den server som samlar in telemetri från alla stationer som lyssnar på FUNCubes, på en helt ny adress: http://data.amsat-uk.org/ 


From:M0XTD

With some luck, Sunday December 2nd will see two more satellites carrying FUNcube payloads launched into orbit.With that launch, JY1Sat and ESEO will join FUNcube-1 (A0-73) and Nayif-1 (EO-88). The FUNcube team have been busy, not only designing and implementing the payloads, but also working on the Telemetry Dashboards and the Data Warehouse. Each satellite has a dedicated dashboard and we have created a one page summary (FUNcube Dashboard Summary v1) of those dashboards, their current version number and a dedicated download link.

Telemetry Dashboard

We have included the recommended warehouse settings for each satellite as well as the “FCD Centre Frequency”. Note that the frequency we quote is 20kHz offset from the published telemetry downlink to allow for the zero hertz spike and close in phase noise that is inherent on SDRs.

Currently, to view the telemetry for a particular satellite, it is necessary to run the dashboard for that satellite. Any telemetry for one of the other FUNcube satellites can be captured and forwarded to the central data warehouse. For this reason, some users tend to run all dashboards simultaneously using the same FUNcube Dongle. Users should remember the that dashboard that was started last, is the one that will control the frequency settings applied to the FUNcube Dongle.

These dashboards are under continual development and the next planned development is to create a single dashboard that will service all FUNcube Telemetry payloads simultaneously. Keep a look out for further news on this unified dashboard in 2019.

Telemetry Data Warehouse

All telemety received via the dashboards is forwarded to the central data warehouse, providing you have registered for an account. This has been a very successful part of the FUNcube project as it has allowed for worldwide data collection by amateurs and for all the data to be available to download and used for educational purposes.

With the pending launch of two additional satellites, some changes where required to allow this data capture to continue in an efficient manner. The data warehouse has a new user interface and all satellite data can be assessed with one URL – http://data.amsat-uk.org . Once at the new user interface, simply select the satellite you are interested in, and all the usual telemetry will be available along with the list of current data providers to the database for that satellite.

Both the dashboards and the data warehouse are under continual development, so be sure to check back for updates.

The FUNcube team is very grateful to all radio amateurs worldwide for their continued support and we encourage you all to join in with the reception of JY1Sat and ESEO telemetry upon a successful launch this Sunday.
