On-board computer with predictive maintenance

On-board computer designed to keep your mission safe

Antelope on-board computer (OBC) is the combination of a Telemetry, Tracking & Command (TT&C) module and a Data Processing Unit (DPU). It is the powerful heart of the satellite, responsible for satellite control and basic 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.

The Telemetry, Tracking & Command (TT&C) module with increased reliability, is responsible for collecting subsystem telemetry, telecommand processing and supervising the operation of the Data Processing Unit.

Data Processing Unit

The Data Processing Unit (DPU) supporting the calculations has a computing performance of over 160 GOPS enabling Earth observation, telecommunication and AI-based applications.

Fault Detection, Isolation and Recovery

A mechanism of detection, isolation and error repair for nano- and microsatellites, extended optionally by the functions of point, contextual and collective Smart Anomaly Detection (SAD), allowing the detection of situations impossible to detect by classic FDIR mechanisms, especially while using out-of-limit (OOL) techniques.

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. An optional layer of security is 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.

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

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 at the beginning of 2023.

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.
