Description

This presentation explores how upcoming space missions like CO2M are addressing challenges in space-to-ground data transmission, especially under unreliable link conditions. It focuses on the use of File Based Operations and the CFDP protocol to improve data handling and reliability. Key differences between CFDP Class 1 and Class 2 are discussed, showing how file size and transaction limits impact data availability. An optimization approach is presented to balance file size, memory constraints, and link performance for robust mission operations.
