BUREAU 1440

Roles:

• Iterative architecture design of Satellite Internet Constellation Network Management System
• Architecture Design
• Solution Prototypes Building

Key Achievements:

• made an HLD for a Unified Space Communications Network Management System based on two previously developed systems: network management system of a ground segment communications and a satellite flight management system. The purpose of this unification is to eliminate duplication of software components and to build a solution for controlling satellite`s devices, ground and gateway stations of the space system on all available communication lines using unified principles. The unified management system allows to remote configuration, to execute control actions (for example, impulses for satellite maneuvering), to update satellite software, to collect telemetry, metrics, logs, and to detect faults in automatic mode to promptly recover the operability of the network element or satellite.
• designed a new Earth-Satellite communication protocol for a management system for the purpose of managing and monitoring the state of satellite devices in an IPv6 network under conditions of high data losses at the physical level.
• designed a workflow orchestration subsystem that helps operational operators coordinate work (configuration, software updates, maneuvering, etc.) for their mutual consistency in a semi-automatic mode.
• designed a solution for automating the process of refining and updating the forecast of the spacecraft's trajectory without the participation of the operation operator. Previously, the operation operator had to recalculate and update the movement forecast for each spacecraft twice a day by conducting a visual analysis of the operation of the calculation algorithms in manual mode.
• organized the migration of the management system to k8s.
• implemented the Architecture as Code approach and organized the development process using Architecture Decision Records.
