| Consider the data connections from Arecibo or Ice Cube (which has many of the same problems). From Wikipedia: > Observational data were recorded on 2-terabyte SATA hard disk drives fed from the Arecibo Telescope in Puerto Rico, each holding about 2.5 days of observations, which were then sent to Berkeley. Arecibo does not have a broadband Internet connection, so data must go by postal mail to Berkeley. https://setiathome.ssl.berkeley.edu/~korpela/papers/CISE.pdf > This 2.5-MHz band is recorded continuously onto 35 Gbyte DLT tapes using 2-bit complex samples. Each tape holds about 15.5 hours of data. The entire sky survey is expected to require 1,100 tapes, for a total of 39 Tbytes of data. > The recorded tapes are shipped to Berkeley, where we subdivide them into small work units on four splitter workstations. ... --- https://icecube.wisc.edu/about-us/facts/ > One terabyte of unfiltered data is collected daily and about 100 gigabytes are sent over satellite for analysis. It's better now (the South Pole does have a broadband link)... but Ice Cube is only sending 10% of its data. |
