What the Data for This Category Looks Like
Data sources for satellite communications financial reports include quarterly and annual official disclosures from satellite operators, public satellite frequency band operation reports released by the International Telecommunication Union (ITU), and industry public documents related to satellite payload operations. Updates to the data follow the disclosure cycle of satellite operator financial reports, with new data released quarterly or annually. Document structures include modules such as satellite constellation parameters, frequency band occupancy, revenue breakdown, and cost composition. Fields cover satellite count, transponder bandwidth (unit: MHz), revenue amount (unit: million USD), launch time (format: YYYY-MM-DD), and some documents include unstructured operation notes and technical descriptions.
What Constraints Do These Characteristics Impose on the Citation Sources and Traceability Link
Structured technical parameters and unstructured business descriptions coexist in satellite communications financial reports. This requires precise matching of technical fields and business context of corresponding paragraphs during traceability, to avoid confusing parameter information of different satellites. The high-frequency disclosure rhythm means the traceability link must connect to the latest knowledge base synchronized data, to prevent use of outdated frequency band occupancy or revenue data. The long document structure creates a need for chunking, which demands that traceability locate specific technical chapters and page numbers, rather than relying only on keyword matching. The special nature of field units also demands retaining original unit information during traceability, to ensure the accuracy of cited content.
How to Set the Configuration
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunk_size | 3000–5000 tokens | Satellite communications financial reports contain long paragraphs of technical parameters and revenue details. This range can retain complete context of business segments and avoid splitting continuous data of the same module |
recall_top_k | 3–7 items | The core data sections of a single satellite financial report are concentrated. This value can reduce the recall of irrelevant paragraphs and improve traceability accuracy |
similarity_threshold | 0.75–0.85 | Technical terms in satellite financial reports have high recognition. This range balances the relevance and coverage of recall, and avoids missing precisely matched detailed parameters |
source_citation_format | {doc_name} + {page_num} + {section_title} | Technical chapters and page numbers in satellite financial reports are core traceability bases. This format can clearly point to specific business segments and improve traceability clarity |
knowledge_sync_interval | 7 days | Satellite operator financial reports are disclosed quarterly. This cycle aligns with the disclosure rhythm and avoids citing outdated data |
max_citation_length | 1200–1800 characters | Parameter descriptions in satellite financial reports are relatively long. This range can retain context while adapting to system context window limits |
The parameter values provided on this page are conventional recommendations used as starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Issue: After setting
max_citation_lengthto 1500 characters, recall chunk lengths still exceed the limit. Cause: In FastGPT 4.6.7, the chunk size is set to 5000 tokens. The text length of a single chunk far exceeds the citation limit, and the system does not truncate single chunks, directly citing the complete chunk. - Issue: The citation sources returned by knowledge base search only show the document name, without page numbers or section titles. Cause:
source_citation_formatis not configured correctly, and only basic document information is extracted, making it impossible to accurately point to specific technical sections in the financial report. - Issue: After calling multiple knowledge bases, traceability results with the same parameters have inconsistent field naming. Cause: Field mapping rules for different source documents are not unified, leading to inconsistent formats of traceability fields returned by different knowledge bases.
How to Verify Correct Configuration
- A local satellite communications financial report sample is uploaded, the knowledge base parsing process is triggered, and the parsed chunk content is checked to confirm that complete technical parameter paragraphs are retained.
- A test query is initiated, such as "Transponder bandwidth revenue status of a certain satellite operator", and the citation sources in the returned results are checked to confirm whether the document name, page number and section title are included.
- The value of
similarity_thresholdis adjusted, multiple rounds of tests are initiated, the relevance of recall results is observed, and the threshold is confirmed to match the current business traceability requirements. - The knowledge base synchronization logs are checked to confirm that the synchronization cycle aligns with the financial report disclosure rhythm, and no outdated data is included in the recall scope.
