This presentation will cover the current status of FPGA firmware and module testing
on the Tangerine SDR system. The system is currently using the MAX10 Development
kit, the Tangerine receiver module and clock module, and an adaptor between the
components and the Development board. The development system used Intel Quartus
version 20.1 on Linux.

As part of HamSCI Personal Space Weather Station (PSWS) project, a low-cost, commercial off-the-shelf magnetometer, which measures magnetic field strength and direction, has been developed to provide quantitative and qualitative measurements of the geospace environment from the ground for both scientific and operational purposes at a cost that will allow for crowd-sourced data contributions. The PSWS magnetometers employ a magneto-inductive sensor technology to record three-axis magnetic field variations with a field resolution of ~6 nT at a 1 Hz sample rate. Data from the PSWS network will combine these magnetometer measurements with high frequency (HF, 3-30 MHz) radio observations to monitor large-scale current systems and ionospheric disturbances due to drivers from both space and the atmosphere. A densely-spaced magnetometer array, once established, will demonstrate their space weather monitoring capability to an unprecedented spatial extent. Magnetic field data obtained by the magnetometers installed at various locations in the US are presented and compared with the existing magnetometers nearby, demonstrating that its performance is very adequate for scientific investigations.

The inspiration for TangerineSDR came from the HamSCI [8] group as a request for SDR hardware that could be used as a Personal Space Weather Station (PSWS). Their need resulted in the four-hour Sunday seminar at the TAPR Digital Communications Conference in Albuquerque, NM, on September 16, 2018. At TAPR, our first response was, {\textquotedblleft}Let{\textquoteright}s find a commercial SDR that we can incorporate into a PSWS kit{\textquotedblright}. Existing hardware would be our best bet for a quick solution. After some research and further consultation with the scientists at HamSCI, it became clear that there was no affordable (less than US $500) solution that met PSWS\ requirements. This article explains the TangerineSDR project and requirements.

This presentation covers some actual hardware that can be used to fulfill the requirements of the HamSCI Personal Space Weather Station project. A new modular hardware architecture is proposed that will fulfill the requirements not only of PSWxS users, but possibly of Phase 4 Satellite Ground Station, academic research, experimenter and general SDR users as well.
