A paper showing AKIDA 1000 being integrated into an on-board processor to help detect fugitive methane emissions from ageing oil and gas infrastructures facilitating operators to locate and mitigate these leaks, to order to help address the global climate crisis. The processor works in conjunction with NASA’s core Flight System (cFS).

.1 BrainSat neuromorphic processor for CubeSats
One of the objectives of our work was to propose an al-
gorithm that could be executed on the novel neuromorphic
on-board processor (OBP) developed by BrainSat [12],
demonstrating its capability to serve small satellite mis-
sion needs and showing the potential of AI-based edge
computing. The OBP was specifically designed accord-
ing to mission requirements established for the monitoring
of point-source methane emissions with a 6U CubeSat, as
detailed in [13].
The designed OBP includes two PC104 modules, con-
nected through a mezzanine connector. It integrates both
CPU and FPGA capabilities and can cater for on board
computer functions, payload data processing and down-
link management. The OBP is equipped with the Akida
1000 neuromorphic processor, selected for its design ma-
turity, real-time processing capabilities and flight heritage.
The chip is tailored for event-based processing, featuring
80 Neuromorphic Processing Units (NPUs) with 100 KB
of SRAM each, supporting up to 1.2 million virtual neu-
rons and 10 billion virtual synapses with up to 8-bit pre-
cision, ideal for inference-heavy tasks. An FPGA pro-
vides glue logic to implement necessary data protocols
and serve as a soft CPU for OBC functions. Additionally,
a 12GB flight-proven Micron Solid State Device (SSD) is
included to provide non-volatile on-board memory. This
sub-system is constrained to a 0.5 U volume and is esti-
mated to consume a low power of less than 4 W.
The processor’s software architecture was designed to
minimize resource consumption. It is equipped with Real-
Time Executive for Multiprocessor Systems (RTEMS) as
its Real Time Operating System (RTOS), on top of which
NASA’s core Flight System (cFS) is used. cFS provides a
flight proven product on which OBP functions are built us-
ing open-source applications. For more information about
the BrainSat architecture, refer to our co-published pro-
ceeding [12]
