CubeSat Debug Tools
To support payload developers, SPUTNIX provides tools such as the SXC-MBB-03 debug baseboard for CubeSats. These tools streamline payload integration and testing, ensuring compatibility with SPUTNIX satellite buses and significantly reducing development cycles.
Satellite Platforms
SPUTNIX offers a family of standardized satellite buses that support varied mission sizes and complexities:
OrbiCraft-Pro CubeSat Platform Line
Ranging from 1U to 12U (SX1, SXC3, SXC6, SXC12), these platforms offer full backward compatibility, meaning payloads developed for smaller satellites can migrate to larger ones with minimal changes. This is ideal for educational and research projects seeking scalability.
The SXC12 is a 12U CubeSat platform designed for Earth remote sensing missions. It includes a full ADCS suite with a star tracker, sun sensors, GPS, angular velocity sensor, and magnetometer. Offering up to 0.1° pointing accuracy and 0.01° stabilization, it supports up to 3 years of orbital operation in LEO. Its compact 30 kg structure supports advanced payloads and a data link of up to 500 Mbps.
Standard CubeSat Platform Configurations
These include service subsystems (power, communication, ADCS) and embedded software libraries, enabling teams to focus on mission payloads while relying on robust and qualified platform subsystems.
SPUTNIX’s SXL-SCoE-ADCS is a ground simulator for testing spacecraft ADCS performance under dynamic conditions. It supports payloads up to 160 kg and simulates solar, magnetic, and GPS conditions. The platform features a 10 µm air bearing gap, 0–4π steradian angular orientation, and precision light spot control ideal for validating ADCS algorithms and calibration procedures before launch.
