Aeropoint challenge

Aeropoint

Command line tool that given a base station ID, start time and end time downloads the day blocks from a given time and merges them into a single RINEX observation file.

One of these networks in the NOAA CORS network in the United States. RINEX observation data from each of their base stations is published in 1 hour blocks on their FTP server at 'ftp://www.ngs.noaa.gov/cors/rinex'. You can read more about the network here: 'http://geodesy.noaa.gov/CORS/'
