[TangerineSDR] Magnetometer testing

[Dr. Nathaniel A. Frissell Ph.D.]

Hi Hyomin and Dave,

This all sounds very good. Dave KV0S also gave us an update last night at TangerineSDR Zoom. I’m looking forward to this!

Dave - thanks for the update.

As Dave mentioned, our prototype magnetometer has been deployed at Jenny Jump. I am expecting to receive data that have been obtained for the past week. The data will be compared with the data from a science magnetometer that is co-located there. I will determine what further testing should be done after the data are examined.

Regarding the discussion 07/07/2020 about the status of the magnetometer performance:

The prototype hardware seems to be working as expected.  From an electro-mechanical point of view, the behavior meets or exceeds the requirements laid down for the project at the time of design.

I am much less clear that the characterization of the sensor has been completed.  Hyomin, David McGraw, John Gibbons and others have said that they were planning to evaluate the sensitivity and other performance parameters.

While offhand comments from Hyomin Kim and Julius Madey have led me to believe that the numbers reported by the sensor are 'in the right ballpark', I have heard no verdict on how good (or otherwise) they are.

Hyomin has deployed the sensor at Jenny Jump, but I'm not certain what his ongoing evaluation plan is.

If Scottie's production of his  'official' TangerineSDR magnetometer design is waiting on sensor characterization, the verdict is still out.

So proceed at your own risk.
