Preview of a future #cyberspectrum talk: Background of passive and active ways to get involved with HAARP experiments (and perhaps with other natural natural ionosphere events) based on prior and ongoing work.

One of Open Research Institute's (ORI) projects is called Phase 4 Ground. Our mission is to provide an open source implementation of DVB-S2 and DVB-S2X for both satellite and terrestrial amateur radio use. Phase 4 Ground radio system has a 5GHz uplink and a 10GHz downlink. We are developing SDR software that heavily leverages IP multicast and RTP protocols to set up and tear down distributed remote radio functions.

The reference designs are in GNU Radio and we will provide recipes for as many SDRs as possible.

Phase 4 Ground radios are intended to be reusable and reconfigurable, supporting payloads at GEO (AMSAT Phase 4B), HEO (AMSAT Phase 3E), and beyond (such as NASA's Cube Quest Challenge). Additionally, our radios will work as terrestrial microwave stations.

SegDSP is a WIP "Segment Digital Signal Processor" that is tuned for connecting into a SPY Server and do automatically demodulation/recording/parsing of RF data: what it does today, how was the development, how it works, how it will work and what are the uses for it. Tired of losing the pass of a LEO satellite? Want to hear the recording from last week? SegDSP is a Open Source tool made in Go for both learning and monitoring Satcom and Terrestrial Com.

Reverse engineering process of the next generation X-Band datalink signal on-board of Sun Synchronous Satellites like Suomi (NPP) and NOAA-20 (NPOESS/JPSS-1). From the RAW I/Q recording to the decompressed high-resolution Earth pictures. This is the latest addition to the Open Satellite Project, a non-profit organization that is committed to develop and publish software tools and hardware projects that enable the Open-Source Community to access spacecraft non-sensitive data.

Also: the “Worst SDR Ever”, which is made entirely of dirty cheap parts readily available from China. This project is intended to demonstrate how a Software Defined Radio works utilizing real hardware and comprehensive modular software.
