SUCHAI-4 Nanosatellite Mission

Tue, 07 Jul 2026 00:00:00 +0000

Overview

SUCHAI-4 is a 3U CubeSat nanosatellite (30 × 10 × 10 cm) developed under an inter-institutional collaboration led by the Space and Planetary Exploration Laboratory (SPEL) at Universidad de Chile, with key software, cybersecurity, and ground system engineering developed by researchers and students from the Department of Computer Engineering (DIINF) at Universidad de Santiago de Chile (USACH) / SCY-FI Lab.

Launched successfully on July 7, 2026, SUCHAI-4 acts as a multipurpose orbital laboratory hosting nearly 60 experiments in space physics, biology (extremophiles), Earth observation, and optics.

DIINF & USACH Contributions

The project was led by SPEL, with the collaboration of academic researchers and undergraduate/graduate students from DIINF / SCY-FI Lab (USACH), who developed key onboard software components, ground control interfaces, and security modules:

Status variables synchronization across OBC: Developed an algorithm to synchronize the status variables between the many OBCs of the CubeSat (Josué Quileñan). Thesis:
Software in the Loop Testing interface: Developed an SIL testing interface for the SUCHAI-FS to interact with space and operational simulators (such as HoneySat) to help testing and validating the SUCHAI-4 Flight Software and the control algorithms early (Felipe Solís). Thesis:
Automatic Flight Operation & Scripting: Developed automated “recipe” execution systems capable of running complex sequential command pipelines autonomously during short orbital communication windows (Lucas Mesías).
Ground Control Interface: Built an intuitive graphical control interface for the SUCHAI Flight Software (SFS), simplifying telecommand transmission and real-time satellite telemetry monitoring (Josué Mateluna).
Low-Cost Educational Groundstations: Developed budget-friendly receiver kits for high schools, enabling students nationwide to receive live telemetry from SUCHAI-4 (Claudia Villa).

DIY Nano-Groundstation for STEM Education

Mon, 06 Apr 2026 00:00:00 +0000

Overview

The DIY Nano-Groundstation is a VIME-funded (Vicerrectoría de Vinculación con el Medio, USACH) outreach and educational initiative aimed at bringing satellite tracking and radio telemetry reception to high school students to foster STEM learning.

By developing accessible, low-cost satellite groundstation kits built on open hardware and Software-Defined Radio (SDR) technology, the project empowers high school students and educators to construct their own satellite receivers, track active operational CubeSat missions in orbit (such as SUCHAI-4), and decode live telemetry and beacon data directly in the classroom.

Technical Details

Open Hardware & Software-Defined Radio: Utilizes accessible, budget-friendly SDR dongles and custom antenna designs for receiving UHF satellite beacons.
Satellite Beacon Decoding: Full pipeline integration for receiving, demodulating, and decoding FSK/GFSK telemetry packets from active CubeSats such as SUCHAI-4.
Educational Hands-on Workshops: Interactive training sessions for high school teachers and students, covering satellite orbital mechanics, radio frequency fundamentals, and embedded signal processing.

HoneySat: Network-based Satellite Honeypot Framework

Thu, 12 Feb 2026 00:00:00 +0000

Overview

HoneySat is the first high-interaction satellite honeypot framework designed to convincingly simulate real-world CubeSats and SmallSats exposed over network interfaces. For years, satellite systems relied on security by obscurity under the assumption that indecipherable proprietary architectures provided sufficient protection. However, modern technological advancements have rendered these assumptions obsolete, opening up satellite communications to potential adversarial attacks.

HoneySat bridges the critical gap in space cybersecurity by capturing real-world satellite adversarial techniques and collecting threat intelligence to develop robust defensive countermeasures.

Technical Details

High-Interaction Simulation: Convincingly emulates the network interfaces, telemetry protocols, and command execution pipelines of operational CubeSats.
Hardware-in-the-Loop Integration: Validated through real-world hardware-in-the-loop operations successfully communicating with an operational in-orbit SmallSat mission.
Threat Intelligence Gathering: Deployed across the Internet to capture live adversarial behavior, collecting real-world interactions without risking active satellite assets.
Operator Validation: Evaluated with small-satellite operators, achieving a 90% realism rating among domain experts.

SUCHAI Flight Software v2

Sat, 15 Mar 2025 00:00:00 +0000

Overview

SUCHAI Flight Software v2 (SUCHAI FS v2) is a highly extensible, modular flight software framework developed for CubeSat nanosatellites and embedded space applications. Evolved from flight-proven software deployed on SUCHAI-1 (2017), SUCHAI-2 (2022), SUCHAI-3 (2022), PlantSat (2022), and SUCHAI-4 (2026). This framework enables rapid development of space missions with heterogeneous teams and multiple payload configurations.

Key Architecture & Technical Features

Command Processor Design Pattern: Decouples command handlers from core dispatchers, allowing developers to register new telecommands and internal routines without modifying core system logic.
Multi-OS Layer Support: Native abstraction layers supporting FreeRTOS for embedded microcontrollers (AVR32, ESP32) and GNU/Linux for embedded single-board computers (Raspberry Pi).
Communication Stack: Integrated with LibCSP (CubedOS Space Protocol) using CAN-bus and ZMQ interfaces for inter-subsystem and ground-station communication.
Flight Inheritance: Inherits field validation from 4 operational nanosatellites in Low Earth Orbit (LEO).
