Our patented satellite Attitude Determination and Control System (ADCS) Sanzar´s Variable Speed Control Moment Gyroscope (VSCMG) array with Linear configuration

\

High Accuracy & Agility

Our ADCS is capable of quickly reorienting the satellite with a 0.0002 degree accuracy. It is capable of accelerating the satellite from zero to its maximum angular rate (130 deg/s on a 3U satellite) in less than 1 second, enhancing satellite communication capabilities and mapping coverage.

\

Effortless Integration

Our ADCS is built with modular VSCMGs of which can be adapted according to the customer’s requirements. We also provide the required algorithms to control the VSCMGs gimbals and flywheels motors to ensure a proper angular momentum delivery.

\

Optimized angular momentum distribution

Our ADCS can deliver all of its angular momentum to one of the satellite axes while being capable to deliver half of its maximum angular momentum to the other satellite axes where no very high angular momentum is required, ensuring very fast maneuvers to ensure a very high coverage area while keeping the ADCS volume very small.

\

Compact & Powerful

Our ADCS fits inside a 1U cube, making it easy to integrate in small satellites.

Advantages

Superior Agility

SANZAR ADCS reaches attitude setpoints 30% more efficiently than traditional reaction wheel systems, achieving 43 successful acquisitions compared to 33. This translates into more observation time per orbit, better data quality, and faster response for time-sensitive applications like disaster monitoring and precision agriculture.

Enhanced Coverage

Our system delivers up to 40% more ground coverage than conventional ADCS solutions across swath widths from 2-100 km. The advantage becomes even more pronounced with high-resolution cameras and narrow swaths, enabling faster revisit times, more data per orbit, and reduced constellation requirements for your mission.

Rapid Stabilization

SANZAR ADCS stabilizes in just 9.87 seconds—330% faster than reaction wheels at 42.53 seconds—providing more time for data acquisition. With 72% improved roll accuracy and 80% better yaw precision, our system enables demanding applications like optical laser communications, quantum systems, and high-resolution imaging.

Constellation Efficiency

Superior area coverage directly reduces the number of satellites needed for your mission. Real-world analysis shows SANZAR ADCS can cover target areas with 50% fewer satellites compared to traditional systems, significantly lowering CAPEX, operational costs, and mission complexity while accelerating deployment timelines.
