Customization
Fligth Software Components
• Application: Mission-specific code, configure services and libraries, start point of the specific application.
• APP Support Library: Packet adaptation layer from PUS (ECSS-E-ST-70-41C - Telemetry and telecommand packet utilization Standard) packet format to internal format.
• Services Library: PUS format routines (services specified in the PUS standard) PUS extension for mission-defined service, and general infrastructure software services. Includes the software library that provides the altitude and orbit control functionality as a software component.
HW Support Library: Software device controller’s abstractions for the OBC.
• Core Library: Software components common to all FSW sharing this architecture. This library provides the basic software infrastructure for all the above layers.
