AWS Ground Station – Ingest and Process Data from Orbiting Satellites. OK this is cool. “Instead of building your own ground station or entering in to a long-term contract, you can make use of AWS Ground Station on an as-needed, pay-as-you-go basis. [...] You don’t need to build or maintain antennas, and can focus on your work or research. We’re starting out with a pair of ground stations today, and will have 12 in operation by mid-2019. Each ground station is associated with a particular AWS Region; the raw analog data from the satellite is processed by our modem digitizer into a data stream (in what is formally known as VITA 49 baseband or VITA 49 RF over IP data streams) and routed to an EC2 instance that is responsible for doing the signal processing to turn it into a byte stream.” # 28th November 2018, 1:04 am
