Payload processors for satellites


A roundup of commercially-available payload processors from around the world, for CubeSats and other satellite form factors.

Payload processor sytems manage the data collected by a satellite payload so that they can be stored, interpreted, and used by the on-board computer (OBC) and communications system. This enables the data to be processed by, or transferred to, other sub-systems when required in order for the satellite system to achieve its primary purpose.

This article gives a brief overview of payload data handling systems and shares details of commercially-available processor products from around the world. If you are familiar with the technology and would like to skip straight to the product listings, please click here.

What is a payload system?

Before explaining how payload processors work, we must first understand what is meant by a payload and a payload system.

The payload is the part of the satellite that gives it its primary function or purpose. The other sub-systems onboard support the satellite’s operational health, positioning, data transfer, power, and other processes that keep it running. But the payload provides the reason to keep that satellite running in the first place.

For Earth Observation (EO) applications, for example, the payload is the camera that is collecting the relevant data. For remote sensing satellites the payload will be the radar or other sensing equipment used to take readings.

Payload satellite communication is the transfer of data relating to the payload’s operation between the satellite and the ground.

To enable this, alongside the primary payload, the full set of antennas, receivers, and transmitters, both in-space and on the ground, used to transmit and store the data needed to meet mission objectives are sometimes referred to as the payload system.

As mentioned, the rest of the satellite (the bus, including the physical structure, electrical power system (EPS), attitude control components etc.) supports the payload and payload system.

What is a payload processor?

Payloads are an important area of innovation in the NewSpace sector. Electronic miniaturization and advances in the manufacture of other supporting sub-systems have brought new capabilities to payload developers.

In addition, innovation from outside of the space sector (such as in radar sensing and camera technology) has also made new missions and services possible.

Therefore satellites can now be launched, deployed, transported, and pointed with greater flexibility and accuracy than ever before. Once in position it is also possible to operate them in new, more powerful, and more responsive ways.

One of the net results of these changes has been greater demands on satellites in terms of data handling and exchange.

Modern EO cameras, for example, can capture more images, at a higher resolution, and in a greater number of formats every year. This requires more processing power in order to handle the data rates and volumes produced.

In addition, the available downlink bandwidth to ground stations can be limited, so satellite payload operators require solutions for coordinating higher volumes of data more efficiently.

The term on-board processing is often used to refer to the activities of the OBC – operational control of virtually all aspects of the satellite requiring computational control or data processing. Payload data processing instead refers specifically to the management of data from an individual payload.

And it is the payload processor that manages this data, and provides a vital connection between the payload, the satellite bus, and the on-board CPU / flight computer system.
