AZST provides engineering design services for space vehicle subsystems and missions. Our employees are experienced in the design, development, and testing of spacecraft hardware and software. We have expertise in all stages of spacecraft design and development, from proposal to on-orbit commissioning, for a wide range of military and NASA spacecraft. Our team designs avionics such as command and data handling boards and payload interface controllers with embedded processors in FPGAs. We can implement complex algorithms for functions such as image processing, navigation, and control. We also have significant expertise in design and analysis of LEO satellite constellations, including coverage analysis, collision avoidance, deployment, and deorbit strategies. Our focus is to support the mission by providing the engineering necessary to ensure the mission science and communication goals are achieved. AZST can assist at all stages of a mission, from the proposal phase to on-orbit operations. We utilize an AS9100 compliant quality management system.
AZST provides specialized payload and instrument electronics for spacecraft including:
AZST can also provide Command and Data Handling boards for the command, telemetry, and payload interfaces in the small sat using protocols such as CCSDS and IP.
AZST avionics boards feature FPGAs enabling custom logic design for mission applications. Our board designs are radiation hardened, with SEU mitigation and error detection and correction in modular, compact, low power form factor. Boards can use embedded processors in the FPGA for real time data processing. We design boards that receive spacecraft commands and send telemetry to the spacecraft radio for transmission to the ground. We also design boards that directly interface with payloads, custom process sensor data, perform data compression, and send the processed data to the spacecraft. Our boards can provide low noise motion and heater control.
Motor Driver Board
AZST has vast experience in flight software. We can provide design of spacecraft guidance, navigation, and attitude control systems. We can also design and implement complex algorithms in software for applications such as constellation coverage and design, navigation filters, and guidance control laws. We can integrate auto-coded algorithms into real time computing environments and develop algorithms for operations such as onboard image processing.
