From Autonomous Cars to Autonomous Satellites, a NN Accelerator Chip Fits Both

Satellites have long been expected to act as autonomous, self-sufficient devices. After all, they’re alone in space.

Yet, the operation of satellites is still largely dependent on crews at ground center, monitoring and often controlling the behavior of the device. Furthermore, satellites generally don’t process the data they’re transmitting or receiving.

This eliminates their ability to independently make real-time decisions with the communicated data.

Space technology company C3S is well aware of these shortcomings and is on a mission to correct them. 

 

The Plan: Take Self-Driving Car Technology to Space

In an effort to create autonomous satellites capable of making real-time decisions, C3S has decided to team up with AImotive, a leader in autonomous vehicle technology. 

AImotive is a multifaceted company in the autonomous vehicle space, providing a stack of AI-specific software, development and validation tools, and hardware. C3S will be looking to leverage AImotive’s hardware, namely their aiWARE automotive neural network accelerator chip. NN acceleration technology is going to be crucial for satellites when trying to perform inference quickly and at low power.

Some of aiWARE’s fundamental features include:

  • A configurable, low-latency, and high-efficiency architecture
  • Optimization of on-chip SRAM and DDR
  • Patented data management techniques

AImotive claims that aiWARE is designed to accommodate the objectives of a vehicle on the road, giving it a unique architecture as opposed to other NN accelerators on the market. 

 

What’s to be Gained by the C3S-AImotive Partnership?

There are many NN accelerators on the market, so you might ask why these two companies specifically joined forces. 

Of all of the fields that incorporate AI, autonomous vehicle technology most closely matches the goals and constraints of an autonomous satellite. AI in autonomous vehicles, like in a satellite, requires the ability to make real-time decisions given unpredictable inputs while simultaneously meeting stringent size and power constraints.

Other popular places for AI, like data centers, run neural networks on large and power-expensive hardware, often lacking the ability, or necessity, to make real-time decisions.

Unlike data center applications, autonomous vehicles and satellites that use AI have no tolerance for any system that needs to periodically clean up buffers, do garbage collection, or otherwise stop for maintenance.

In a whitepaper from AImotive on the importance of offloading data processing (PDF), the company explains, “For automotive embedded inference, the memory strategies used must be robust under all conditions, and work continuously without fail.” To this end, AImotive has secured many patents focused primarily on data flow and management. 

The companies’ shared goals make AImotive’s expertise suited for space applications.

 

Space-Specific Limitations to aiWARE

That’s not to say that the two technologies are perfectly cohesive, and there are definitely hurdles to be overcome. aiWARE is going to need C3S’ expertise to help convert its products to ones that will be able to withstand the demanding habitat of space.

Considerations in space that earth-bound vehicles seldom encounter include heat fluctuations and cosmic radiation. 

 

From Autonomous Vehicles to Autonomous Satellites

The partnership between these two companies provides yet another example of how fully autonomous satellites may be a realistic possibility in the future. Satellite applications that require immediate action like natural disaster detection, weather forecasting and alerting, and cargo tracking will likely see huge benefits from AI being brought into space.
