Remote Labs Equipment Review

Transcript of Introductory Remarks

Greetings all,

Welcome to the Open Research Institute Remote Labs Equipment Review.

Open Research Institute (ORI) is a non-profit research and development organization which provides all of its work to the general public under the principles of Open Source and Open Access to Research.

Remote Labs are two physical lab benches. They have equipment for advanced digital communications design work. This equipment will be accessible online to anyone, anywhere that wants to work on open source amateur radio satellite service or open source amateur radio terrestrial engineering development.

The primary focus of the equipment list reviewed today is to support the design, verification, and test of the DVB family of links. DVB-S2, S2X, and T2 are all commonly found in amateur radio. DVB-S2X is the protocol family used by Phase 4 Ground and Space.

Remote Labs is a part of an extremely important process of re-establishing free and open international collaboration with groups such as AMSAT-DL, JAMSAT, and AMSAT-UK, and to increase and amplify collaboration with Libre Space and other open source groups. This is possible for ORI to do by using the open source carve-outs in the US export control regulatory framework. These controls have impeded international cooperation on amateur satellite work for a long time.

A significant amount of regulatory relief was achieved over the summer by ORI for amateur radio satellite work, and more work is going on right now to build upon this success. Please see the Open Research Website news section for more details on that. Today’s discussion is not about satellite technology, but about the equipment and resources required.

We are fortunate to have the advice and input of people that make a living by using remote labs at work. The advice received so far has been heard and acted upon. Python, HTML5 plus Javascript, and command line access will be the initial methods upon to provide secure access to the equipment.

We will not be writing or using a heavy or complex software framework for the Remote Lab. We will be authorizing and authenticating users. It is highly likely that we will use the same authentication and authorization approach that we intend to use for payload communications access, in order to get more experience with that design. In other words, you may be authenticated and authorized for Remote Labs the same way that you will be authenticated and authorized for the payload communications system.

We will definitely be documenting how to use the lab. We will be responsive to feedback about accessibility and ease of use.

There will be someone physically present at the Remote Labs. The equipment is not installed in racks at an unattended site. If a function needs on-site setup, or a test plan can only be done with someone physically at the bench, then that’s how the work will be done.

Remote Labs is offered as a community resource. Therefore, the review process must include community feedback. Thank you for your time here today to discuss and review the equipment list.

As an example, Thomas Parry has provided the following feedback.

1) The initial list had no power supply listed.

2) A computer controlled coax switch matrix would be very useful to control where the signals are going between test gear, DUT, etc. without physical intervention

3) Some form of general purpose digital/low frequency IO device like an analog discovery would be pretty useful for controlling things remotely

4) A way to get arbitrary RF in and out of the PC, ie. an SDR, would be very useful

5) And please remember cabling.

Wally Ritchie responded with an updated list that includes coax relays controlled from a USB relay board(s), and the other items.

Our practice will be validate and measure any cables we make in-house, buy, or obtain as surplus or donations.

I can answer your questions about budget, operation, and policy at the close of the review, or via email.

Please welcome Wally Ritchie who will lead todays Remote Labs Equipment Review.

P4XT (Phase One) Workshop Design Review

Learn about our work on the digital microwave broadband transponder for amateur radio.

https://www.youtube.com/watch?v=QXiWCgo10lg

All work is donated to the general public as open source.

This digital multiplexing transponder is a regenerative design, taking full advantage of a wide variety of cutting edge technology, intended for amateur radio use in space and terrestrial deployments.

This review focuses on decisions made for the prototype board set that implements the transmitter side of the payload.

Comment and critique welcome and encouraged.

Yasme Foundation Generously Awards Grant to ORI

Yasme Foundation Generously Awards a $30,000 Grant to Support the Open Research Institute (ORI) Amateur Radio Satellite Service Research and Development Program

ORI, a 501(c)(3) dedicated to open source research and development in amateur radio, has been awarded a $30,000 grant from the Yasme Foundation. This grant completes the Phase 1 fundraising campaign and allows ORI’s communications prototype work for geosynchronous and interplanetary amateur radio satellites to proceed.

Combined with the ARRL Foundation’s recent maximum grant of $3,000, the $14,000 in proceeds from ORI’s successful Trans-Ionospheric electronic badge fundraiser, and many deeply appreciated individual donations, a total of $51,490 was raised for Phase 1 of the Digital Multiplex Transponder research and development program.

A project that will directly and immediately benefit from this work includes the Amateur Radio Exploration (AREx) project, brought to you by Amateur Radio on the International Space Station (ARISS).

AREx is devoted to designing and building amateur radio equipment for the Lunar Orbiting Platform Gateway project. This lunar orbiting station will have open source broadband microwave amateur equipment and affordable open source ground stations. AREx is not limited to Gateway, as there are many other opportunities under consideration that can re-use all of the work.

All work completed by ORI is made available to the general public at no cost.

The Yasme Foundation is a 501(c)(3) not-for-profit corporation organized to support scientific and educational projects related to amateur radio, including DXing (long distance communication) and the introduction and promotion of amateur radio in developing countries. Yasme supports various projects relating to amateur radio, with an emphasis on developing amateur radio in emerging countries and encouraging youth participation in amateur radio.

The Yasme Foundation makes supporting grants to individuals and organizations providing or creating useful services for the amateur radio community. Regardless of originality or novelty, Yasme supports these programs in order to further the development of amateur radio around the world.

The global perspective and commitment to authentic, accessible, and sustainable amateur radio training and experience puts Yasme Foundation into the rare category of organizations that provide true and broad public benefit.
