On-board computer designed to keep your mission safe

On-board computer designed to keep your mission safe

Antelope combines an On-Board Computer (OBC) and a Data Processing Unit (DPU). It is the powerful heart of the satellite, responsible for satellite control and essential task performance such as communication handling, monitoring the satellite’s subsystems, handling the classic Fault Detection, Isolation and Recovery (FDIR) mechanism and performing planned tasks.

Thanks to the powerful (160 GOPS) FPGA system it can also handle complicated on-board data processing tasks enabling Earth Observation (EO), telecommunication and other demanding data processing applications.

Do you want to make your mission safer?



The On-Board Computer PC-104 form factor, based on Hercules RM57 expanded with 8 or 16 MiB of MRAM and 4 or 8 GiB of NAND Flash memory


The Data Processing Unit module supports the calculations with Zynq Ultrascale+ MPSoC, expanded with 8 GiB of DDR4 and 8 GiB of NAND Flash

Antelope was designed to maximize spacecraft safety. Thanks to customised mechanisms which protect against effects related to space radiation it can be applied in more demanding missions. There is an option for additional security level provided by the machine learning algorithms which, on the basis of telemetric data, detect events which may be considered as threatening to the security of the mission. If such an event is detected, the computer will notify the operator in order to take corrective action. The DPU could also be paired with the different sensors and analysed their data in situ.

Antelope is part of the Smart Mission Ecosystem – hardware, software, and AI-powered algorithms designed to complete your mission.

Expert tool for annotating anomalous signals

Anomaly annotator

We create an anomaly annotator graphical tool for labelling time series data. This tool is based on the open-source TRAINSET application by Geocene Inc. However, we significantly improved it in terms of performance and added a bunch of features for working with long multi-channel time series (such as satellite telemetry). Go to website.

Case study

Antelope will be utilized by the PW-Sat3 satellite, coupled with KP Labs’s on-board computer software – Oryx.

PW-Sat3 is an in-orbit demonstrator of new cold gas propulsion and is planned to be launched in late 2024.

Antelope will be responsible for satellite management and mission safety.


Mission Safety

20 kRad tolerance and SEE protections. Classic FDIR mechanisms. Optional Artificial Intelligence for preventive failure detection of all types of anomalies: point, contextual, collective

Mission Power

160 GOPS of computing power enables exciting possibilities in Earth observation, telecommunication and AI-based applications

Mission Extensibility

Compatibility with Leopard Data Processing Unit. By pairing Antelope and Leopard you can extend the onboard processing power by 3000 GOPS to enable the processing of more demanding calculations
