What is the greatest accuracy that a satellite can measure Faraday rotation (FR)?
As an example, this paper states that FR can be measured to + or - 2 degrees for ATS-6:
An Epuipment to Measure Faraday Rotation Angle of VHF Waves Received from a Geostationary Satellite
Article in IETE Journal of Research 23(12) · December 1977
DOI: 10.1080/03772063.1977.11451514
Has FR been measured more accurately using ATS-6 or another satellite since this time?
Thank you for contributions to this discussion in advance.
Best regards.
Hello Alex.
I think paper attach below can solve all yours questions.
The paper was published in "IEEE TRANSACTIONS ON GEOSCIENCE AND REMOTE SENSING, VOL. 52, NO. 8, AUGUST 2014"
Enjoy.
Emilio.
Thank you Emilio Ramirez-Juidias. I came across that paper during my initial search; "accurate satellite Faraday rotation (FR) measurement", but this paper states "at worst 5 degrees" for the SAR data discussed. I have been mainly considering ATS-6 data because FR and Total Electron Content are measured independently. I was hoping to find a characteristic value for a benchmark that FR could be measured that was better than + or - 2 degrees. Nevertheless, thank you for highlighting this paper for a complete discussion of this topic.
