ARLA/CLUSTER: AO-92 - PicSat solicita ajuda aos radioamadores para capturar / enviar dados de telemetria

PicSat requests Ham Radio assistance to capture/ upload telemetry

The Cubesat PicSat was launched on the same PSLV-C40 flight from India
that delivered AO-92 to orbit

PicSat is a nano-satellite aimed at observing the transit of the young
exoplanet Beta Pictoris b in front of its bright and equally young
star Beta Pictoris, and at demonstrating an innovative technological
concept to use optical fibres for astronomical observations from
Space.

The CubeSat contains an embedded FM transponder. It will be available
when possible during the mission.

Frequency information:
Uplink FM    145.910 MHz  1750 Hz tone when in amateur mode
Downlink FM  435.525 MHz  9k6 BPSK AX25 Data and FM voice when in amateur mode

A description of the telemetry and related information are available on
https://picsat.obspm.fr/data/telemetries?locale=en.

This week the PicSat team requested amateur radio assistance to
capture and upload telemetry packets from the satellite. Beacons
received from all over the world are especially useful to monitor the
status of satellite along its orbit (and not just when it is above our
own station).

Science data are obviously useful for the science mission. And all
other packets, even when they do not look like much, can be of great
importance! For example, we often receive satellite acknowledgements
to our commands from ground station in France or Europe which are
listening at the same time as us. It may look useless, but it is not.
We regularly miss those packets ourselves, so it is good to have other
people receiving them and sending
them to us.

There are three ways to send your data. The options for your upload
will become available on your profile tab after registration at their
website:

Full details of the packet uploading procedure are posted at:
https://picsat.obspm.fr/contributing/send-packets?locale=en

+ Fast upload beacon: mainly intended as a way to directly upload a
beacon by copy/paste when you receive, and to get an immediate
overview of the satellite status. When you are a new user, this is
also the only way you can upload a packet. Upload one beacon
successfully, and you will have access to the other methods!

This page accepts a hexadecimal string, like "0123456789ABCDEF" in
which whitespaces and upper/lower case are ignored ("01 23 45 67 89 ab
cd ef", or even something like "0 1 234 56789 aBc dEf" will be
accepted). The hexadecimal string must represent the AX.25 packet
(without flags), possibly KISS encapsulated (starting with "C0 00" and
ending with "C0")

+ Upload data: this can be used to upload files containing multiple
packets at once. The files are stored on our servers, and processed
daily.

+ SiDS requests: This will be implemented in the near future.

PicSat shares a similar orbit with AO-92 since they were both deployed
at approximately the same time. PicSat has been included in the 2 line
Keplerian Elements distributions. On-line orbit predications for
