Is there any error correction in the data stream? I mean, if we loose e.g. 1 minute of data, will it just be sent after the full data had been sent, or how do we ensure that we grt valid data over such a huge distance?
- tams 11y agoAll long range transmissions use forward error correcting codes which allow error detection and data recovery without retransmission (to a certain degree). See [1] (paragraph 2.5 on page 10) for a bit more on the kinds of FECs used. [1] http://deepspace.jpl.nasa.gov/dsndocs/810-005/208/208B.pdf http://deepspace.jpl.nasa.gov/dsndocs/810-005/208/208B.pdf
