GPS Raw data (SNR) in Solo

Does anyone how can it be gotten the raw GPS data from the 3DR Solo, to get the GPS signal strength?? (azimuth, signal-to-noise ratio, PNR, elevation).

I found the info is there mavlink.org/messages/common#GPS_STATUS, but I would like to have this data in a log.file in the solo drone, please any help is highly appreciated.
