What Data for This Category Looks Like
Data sources for satellite communications financing daily reports include publicly disclosed documents from space launch regulatory bodies, official project announcements from satellite operators, and private financing ledgers from financial institutions. Updates are published every early morning, covering the previous day’s industry financing updates. Each document includes fields such as unique project identifier, satellite model, orbital altitude, communication frequency band, financing amount, investor list, landing region, and signing date. Unit specifications: orbital altitude in kilometers, communication frequency band in GHz, financing amount in ten thousand yuan or hundred million yuan, and landing coverage area in square kilometers.
Constraints Imposed on Knowledge Base Retrieval and Recall
The daily update rhythm requires configuring scheduled incremental synchronization tasks to avoid excessive system resource usage from full data pulls. The presence of multiple specialized fields requires prioritizing matching core business fields during retrieval to prevent overly general recall of irrelevant content. Some documents contain long-text feasibility study reports, so reasonable chunking parameters must be set to avoid context breaks that reduce recall accuracy. Fields such as financing amount and signing date have strict format and precision requirements, so field-level validation rules must be configured to ensure matching accuracy.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 2000 MB | Feasibility study reports, launch plans and other supporting documents for satellite communications financing daily reports typically do not exceed 1500 MB per file, so reasonable redundant space is reserved |
PARSE_FILE_TIMEOUT_SECONDS | 900 seconds | Parsing large satellite project feasibility study documents takes significant time, the default timeout duration is insufficient to complete the parsing process |
| Chunk Length | 800–1200 characters | The combined core data of a single satellite communications project is moderately sized, balancing recall accuracy and context completeness |
| Number of Retrieved Entries | Top 6 | The number of core projects in financing daily reports is typically concentrated; excessive retrieved entries will interfere with business decision-making |
| Similarity Threshold | 0.72–0.85 | There are many specialized domain terms; a higher threshold can filter irrelevant general communications content |
RETRIEVE_PRIORITY_FIELD | Financing Amount, Signing Date | Business users typically prioritize core business metrics when conducting searches; prioritizing retrieval improves result practicality |
The parameter values provided on this page are all conventional recommendations used as a starting point for configuration. Actual values are affected by material format, data volume and business rules. Specific issues require case-by-case analysis, and it is recommended to conduct tests on your own samples before finalizing settings.
Three Common Misconfigurations
- Phenomenon: A
504 Gateway Timeouterror occurs when uploading satellite project documents larger than 1000 MB. Cause: ThePARSE_FILE_TIMEOUT_SECONDSparameter was not adjusted, and the default timeout duration is insufficient to complete parsing of large documents. - Phenomenon: Search results contain content from multiple business categories, and it is impossible to distinguish modules such as business systems and expert interpretations. Cause: Exclusive collection IDs were not bound to different types of documents, resulting in failure to isolate data by knowledge base during recall.
- Phenomenon: Retrieval results lack core business fields such as financing amount. Cause: Priority retrieval business fields were not configured in
RETRIEVE_PRIORITY_FIELD, resulting in auxiliary data being returned first.
How to Confirm Configuration is Complete
- Upload a satellite communications project feasibility study document of approximately 1000 MB, verify that the parsing progress completes normally with no timeout errors.
- Search for "2024 low-orbit satellite financing projects", check that the signing dates of returned results fall within the current day or specified cycle, and that specified fields such as financing amount and communication frequency band are included.
- Adjust the similarity threshold to 0.7, search for the specialized term "Ka-band", verify that irrelevant civilian communications frequency band content is filtered out of returned results.
- Batch upload multiple small and large documents, verify that the upload queue prioritizes processing smaller files, which matches the expected scheduling logic.
