Expanding space horizons by enchancing satellite orientation agility
Reducing the number of deployed satellites by increasing the coverage area per satellite
Our patented satellite Attitude Control System (ACS) Sanzar´s Variable Speed Control Moment Gyroscope (VSCMG) array with Linear configuration
High Accuracy & Agility
Our ACS 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 ACS 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 ACS 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 ACS volume very small.
Compact & Powerful
Our ACS fits inside a 1U cube, making it easy to integrate in small satellites.

Why Sanzar Group?
Limited Current Capabilities
Current satellite ACS have a limited Torque/Volume ratio of which restricts the operational range of a satellite's service capabilities. This limitation also requires the deployment of additional satellites to cover the desired terrain.
Missed Oportunities
Single satellites currently in orbit have a potentially larger service range that remains untapped due to their ACS limitations. This results in a significant opportunity loss, as the full potential of individual satellites is not being utilized.
Advanced ACS Performance
Our ACS offers a high torque/volume ratio compared to existing market proposals, enabling an enhanced satellite maneuverability. This leads to lower operational costs and ultimately decreases space debris by diminishing the necessity to launch additional satellites.
