Here’s an interesting thought: it’s possible to build a cubesat for maybe ten thousand dollars, and hitch a ride on a launch for free thanks to a NASA outreach program. Tracking that satellite along its entire orbit would require dozens or hundreds of ground stations, all equipped with antennas and a connection to the Internet. Getting your data down from a cubesat actually costs more than building a satellite.
This is the observation someone that Amazon must have made. They have developed the AWS Ground Station, a system designed to downlink data from cubesats and other satellites across an entire orbit. Just now, Amazon only has two ground stations attached, but they are planning to have a box in place at the middle of next year. Hver af disse jordstationer er forbundet med en bestemt AWS-region (der er et total af seksten AWS-regioner, som kan begrænse orbitaldekningen af AWS Ground Station-systemet), og består av en antenne, en alt-az mount, og a gigantic bank of servers and hard drives to capture data from satellites orbiting overhead.
The Amazon blog post goes about how easy it is to capture data from a satellite, and it’s as easy as getting a NORAD ID, logging into your AWS account. , and clicking a few buttons.
It should go without mention that this is the exact same idea behind SatNOGS, an Open Source global network of satellite ground stations and winner of the 201
4 Hackaday Prize. Één van hun grondstations is wat er afgebeeld bij de top als deze artikel. Right now, SatNOGS has over seventy ground stations in the network, including a few stations that are in very useful locations like the Canary Islands. The SatNOGS-netwerk har allerede en masse mere dækning end det maksimale af seks steder, hvor Amazon har deres datacentre – gjort muligt af dets åbne natur. Congrats to the SatNOGS team once again for creating something so useful, and doing it four years before Amazon.
