Antelope – On-Board Computer (OBC) with predictive maintenance

SUMMARY

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.

Antelope was designed to maximize spacecraft safety. Thanks to customised mechanisms which protect against effects related to space radiation it can be applicable 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, software and AI-powered algorithms designed to complete your mission.

ANTELOPE IS BUILT OUT OF 3 KEY ELEMENTS

1. TT&C

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.

2. 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.

3. 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.

OPERATING SYSTEM

Antelope is managed by Oryx – a modular flight software tool developed for the mission control of small satellites. Thanks to its modular architecture, based on building blocks, it supports the rapid development of the mission’s software by using a vast library of components – logging, scheduling, testing and communication to name but a few. Oryx exposes an API that can be accessed by the small Lua scripts, providing access to selected sensors and peripherals.
