Historically, imagery data was compressed and stored on board the satellite however, more efficient use of the data relay network providing connection to the ground station can be accomplished by performing a greater amount of data processing on board the satellites so that information can be transmitted to the ground, instead of raw data. It is impractical for low earth orbit (LEO) imaging satellites generating tens of gigabits per second of data and orbiting the earth roughly 16 times a day to send a constant stream of data to the ground through a space relay network. Organizations purchasing satellites are on a perpetual quest to extract ever-increasing value from space assets: We see operators of imaging satellites seeking higher image resolution, faster frame rates, finer channel resolution, and more channels to enable advanced multispectral and hyperspectral imaging.Īs designers create imaging payloads with sufficient resolution to meet the needs of satellite operators, they encounter the perennial problem of constrained downlink bandwidth.
