On its two Voyager missions, NASA used (still uses!) a RS encoder/decoder that can correct up to 16 error bits per frame. It became a standard for a number of subsequent missions. This was in an era before ASICs and FPGAs yet the hardware still had to meet strict size, weight, and power requirements. Not to mention maintaining comms over distances greater than 14 billion miles and received signal strengths of 10^-16 watts. Truly humbling. |
