Commissioning Milestone Enables Precise Control, Power Optimization, and Mission Readiness

Sidus Space (NASDAQ: SIDU), (the Company or “Sidus”), an innovative space and defense technology company, today announced the successful deployment of its new autonomous guidance, navigation, and control (GNC) software, SpacePilot and commissioning of the Attitude Determination and Control System (ADCS) on LizzieSat^®-3 (LS3).

Designed for next-generation satellite operations, SpacePilot integrates real-time star tracker, sun sensor, magnetometer, gyroscope, and GPS data onboard LS3 to enable high-precision orbital control with minimal ground intervention. Key features include:

• Attitude Determination: Real-time estimation of spacecraft orientation for mission-critical accuracy
• Attitude Control: Stabilization and mission-aligned adjustments to support payload operations
• Optimal Trajectory: Fuel-efficient, time-optimized flight paths for extended mission life
• Autonomous Guidance: Precise rendezvous and proximity operations (RPO) with minimal operator input
• Adaptive Autonomy: Dynamic response to changing orbital conditions and fault scenarios
• Lightweight Design: Optimized for resource-constrained small satellite platforms

“Activating SpacePilot and commissioning the ADCS marks a critical milestone for LS3’s mission,” said Carol Craig, Founder and CEO of Sidus Space. “This software enables a higher level of autonomy, ensuring greater efficiency and mission resilience while reducing reliance on ground resources.”

The successful commissioning of the ADCS marks a critical step toward LS3’s full mission readiness. With the deployment of autonomous SpacePilot, the satellite can achieve accurate sun-pointing for maximum power generation, stabilize payload orientation for improved data collection, and maintain antenna alignment for reliable communications. This milestone also paves the way for more rapid commissioning of the remaining onboard technologies, including Sidus’s proprietary sensor suite.

LS3’s successful commissioning and SpacePilot deployment reinforce Sidus Space’s commitment to advancing autonomous satellite technologies as part of its growing LizzieSat^® constellation.
