What the data for this category looks like
The data sources for satellite communications marketing content include satellite operator official frequency band documents, link test reports, coverage area plans, and industry marketing script templates. The data update rhythm changes irregularly alongside frequency band policy adjustments, link operation and maintenance optimization, and marketing campaign launches. Document structures include numeric parameter tables, long-form technical descriptions, and short-text marketing scripts. Fields involve uplink frequency, downlink frequency, EIRP value, coverage radius, and more. Units are mostly MHz, dBW, and km.
What constraints these characteristics impose on retrieval and recall
Numeric parameters in satellite communications data require range matching during retrieval. Adjust the numeric encoding logic of the vector model to avoid parameter matching deviations. Set reasonable segmentation thresholds for long texts from link test reports to prevent loss of associated parameter descriptions after splitting. Adjust similarity matching rules for short marketing scripts to avoid irrelevant content being included in recall results. Shorten the knowledge base synchronization cycle for irregularly updated operation and maintenance documents to prevent recall of outdated policies or link parameter content.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 1500 MB | Satellite communications marketing documents often include large link test reports and frequency band allocation manuals, so the single-file upload limit needs to be relaxed |
Segment Length | 900–1100 characters | Technical paragraphs in satellite communications documents are mostly 900–1100 characters long. Segmentation preserves complete associated parameter descriptions |
Recall Count | Top 6 entries | Marketing content needs to cover multi-dimensional materials such as frequency band plans, script templates, and coverage areas. 6 entries balance recall coverage and result accuracy |
SIMILARITY_THRESHOLD | 0.72–0.80 | Similarity matching for numeric parameters and short marketing scripts in satellite communications requires a balance between precise filtering and recall completeness |
PARSE_FILE_TIMEOUT_SECONDS | 1200 seconds | Parsing large satellite documents requires processing complex tables and formulas, so the timeout threshold needs to be extended to avoid parsing interruptions |
KNOWLEDGE_REFRESH_INTERVAL | Every 7 days | The update cycle for satellite frequency band policies and link parameters is mostly quarterly. Synchronizing every 7 days covers temporary operation and maintenance adjustments |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Phenomenon: When uploading a 190 MB satellite link test report in Community Edition v4.9.1-fix2, the interface returns the
offset is out of boundserror, and the parsing task fails. Cause: TheUPLOAD_FILE_MAX_SIZEandPARSE_FILE_TIMEOUT_SECONDSparameters were not adjusted. An offset calculation error occurs during segmented upload of large files, and parsing time exceeds the default threshold, triggering an interruption. - Phenomenon: After deploying a 70B large model, the response time for marketing content associated with the knowledge base exceeds 25 seconds. Logs indicate lag during the model inference stage. Cause: The total character count of recalled documents was not limited. Too many long paragraphs of satellite communications documents are included in the context, exceeding the effective inference range of the model.
- Phenomenon: A large number of irrelevant old frequency band policy documents are mixed into knowledge base recall results, failing to match current marketing needs. Cause: The
KNOWLEDGE_REFRESH_INTERVALparameter was not set. The knowledge base does not synchronize updated satellite operation data, resulting in recall of outdated content.
How to confirm the configuration is correct
- Upload a single satellite link test report of approximately 200 MB, check whether the upload and parsing tasks are completed successfully, and adjust relevant parameters based on the results.
- Initiate a test query containing frequency band parameters and marketing scripts, verify the count and matching degree of recall results, and adjust recall-related configurations based on matching effects.
- View the knowledge base synchronization logs to confirm whether the latest satellite operation documents have been updated within the set cycle, and adjust synchronization parameters based on update frequency.
- Initiate a test query containing long technical paragraphs, check whether the model response retains complete associated parameter descriptions, and adjust segmentation parameters based on response completeness.
