[Ground-station] FPGA roll call - efforts in September 2023 and moving forward

[Michelle Thompson]

Greetings all!

This mail is for those that are interested in the next batch of FPGA work
at ORI. It's also copied to the mailing list to include those that have
recently joined or become available.

First of all, thank you for your time and energy. It's deeply appreciated
and we can't do what we are doing without you.

If you are ready and willing to join up for this next season of work
(October - December 2023), then please respond to this message so that we
can support you.

Please be introduced to Anshul Makkar, a member of our Board of Directors.

Anshul will be coordinating work on the Haifuraiya transponder. This uses
the ADRV9009 and ZCU706. A set of this hardware is accessible from chococat
virtual machine in Remote Lab West. This is a microwave band transceiver
with a 5GHz time-division multiplex DVB-S2/X downlink, a 10GHz
frequency-division multiple access Opulent Voice uplink, and multiplexing
in the payload. The encoder can be found at
https://github.com/OpenResearchInstitute/dvb_fpga and Opulent Voice general
purpose processor code and links to the protocol documentation can be found
at https://github.com/OpenResearchInstitute/opv-cxx-demod

We are adapting Theseus Cores for our uplink receiver, we need an Opulent
Voice receiver in the payload, and we need to get DMA transmission working
(again) on the ADRV9009.

There's a substantial amount of work that has been done, and a long way to
go. The design is ambitious. It is also achievable.

Please be introduced to Leonard Diguez, who coordinates the Neptune Project.

Neptune is an OFDM-based point-to-point link intended for drones. This uses
the ADRV9002 and ZCU102. A set of this hardware is accessible from keroppi
virtual machine in Remote Lab West.

The Neptune repository can be found at
https://github.com/OpenResearchInstitute/Neptune The repository has the
physical layer specification and some simulations. Leonard is looking to
get the physical layer implemented and tested over the air. This will be at
5GHz.

A floating license for the current version of Vivado is installed. Vivado,
Vitis, and Petalinux are available on both chococat and keroppi.

A full version of MATLAB is available on keroppi including HDL Coder. HDL
code created with HDL coder is very readable and open source compliant. Our
default HDL license is CERN OHL version 2.0.

See

https://github.com/OpenResearchInstitute/documents/blob/master/Remote_Labs/ORI-Lab-User-Setup.md

for instructions on how to get an account to access the virtual machine.

***Make sure you've joined #fpga channel on ORI Slack and any individual
project channels.***

We will resume weekly FPGA meetups 19 September 2023 1000 US Pacific. The
goal is to be as brief as possible following this format: reports on
previous work, plans for upcoming work, any resources needed, and if there
are any roadblocks. Meetings are recorded and published to ORI YouTube by
default. Office Hours following the meetup are not usually recorded. Office
Hours are open discussion.

Please share our Getting Started page to anyone you think might want to
join or follow along.
