| It's a radio telescope, how would you imagine translating that to bytes? |

| Here's an article mentioning the data transmission rates in SKA, up to 20 terabits per second: https://www.skao.int/en/explore/big-data |

| Every sensor in the array is sampling at frequency, so - first order - you can use that sampling frequency and the sample size, you get an idea of the input bandwidth in bytes/second. There are of course bandwidth reduction steps (filtering, downsampling, beamforming)... |

| ▲ | touisteur 2 hours ago | parent [-] | | On SKA from what I understand they're sampling broadband but quickly beamform and downsample as the datarates would be unsustainable to store over the whole array. | | |
| ▲ | jacquesm an hour ago | parent [-] | | Right, that makes sense, you'd be looking at an insane amount of data across the ranges that these sensors can look at. But they would still need to preserve phase information if they want to use the array for what it is best at and that alone is a massive amount of data. |
