$REC Consumption The encrypted payload should be carried in the generated $REC wrapper so Bob can identify the generated schema type and run the correct decrypt path.
Per-Field Protection Fields marked (encrypted) stay in their generated FlatBuffer layout while sensitive bytes, such as KMF.KEY_BYTES, are protected for the intended recipient.
1 Read $ENC Before Payload Bob must parse the encryption header first to recover the ephemeral public key, nonce base, and generated root type information.
2 Consume the Generated $REC Wrapper The payload should be consumed through generated REC bindings so Bob can resolve the record type and dispatch to the correct generated schema before decrypting fields.
3 Decrypt Encrypted Fields In-Place Once Bob derives the shared secret from the header, he decrypts the encrypted fields in the generated payload buffer and then reads the normal generated object graph.
1 Public Network Distribution Share CDM messages on public networks where routing information must be visible but collision details are protected.
2 Multi-Party Access Control Different fields encrypted for different recipients. Satellite operators see their own data, regulators see aggregate statistics.
3 Audit-Friendly Sharing Message metadata remains visible for logging and compliance while payload stays confidential.
1 Parse TLE Lines Extract epoch, mean motion, eccentricity, inclination, RAAN, argument of perigee, and mean anomaly.
2 Add Metadata Include OBJECT_NAME, OBJECT_ID, CENTER_NAME, REF_FRAME, TIME_SYSTEM that TLE lacks.
3 Serialize to FlatBuffer Use SDS library to create type-safe, compact OMM message.
Integrate existing XTCE telemetry databases with the XTC FlatBuffer format for high-performance ground systems.
1 Export XTCE Database Export your telemetry database to standard XTCE XML format from your existing tools.
2 Convert with SDS Tools Use SDS conversion utilities to transform XTCE XML to XTC FlatBuffer format.
3 Deploy XTC Database Use compact XTC files in your ground system. Memory-map for instant access to parameter definitions.
