What the data for this category looks like
Data sources for satellite communications financial reports include quarterly and annual public financial reports from satellite operators, frequency band filing documents from industry regulatory authorities, and special reports on satellite constellation deployment. Update cycles follow quarterly and annual schedules. Document structures include sections such as business revenue, frequency band usage, satellite constellation deployment counts, ground station operation and maintenance data. Fields cover professional technical parameters including bandwidth (unit: MHz, Gbps), orbital altitude (unit: kilometers), and operational duration (unit: years). Some documents include structured tables and technical appendices.
What constraints these characteristics impose on document parsing and chunking
The professional technical parameters and fixed structure of satellite communications financial reports require the parsing process to fully retain units and specific terminology, and avoid breaking parameter associations during chunking. Quarterly and annual update cycles mean documents use fixed templates with minor format adjustments each year. The system must adapt to dynamically changing field structures. Large structured tables require that chunking does not split associated data within tables. Otherwise, subsequent analysis will fail to match frequency bands to corresponding revenue. Some documents include encrypted or specially formatted PDF attachments, so the system must support non-standard parsing logic.
How to set the configurations
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
maxChunkSize | 800–1200 characters | Satellite communications financial reports contain technical parameters and revenue data. Chunks that are too long will lose parameter associations, while chunks that are too short will disrupt business logic. This range fits most financial report document structures |
chunkOverlap | 100–150 characters | Cross-chunk associated information such as frequency band and orbital parameters must be retained. The overlap length must cover the context of core technical terms |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Satellite financial reports often include large tables and technical appendices. Parsing takes longer than general documents, so the timeout threshold must be extended |
enableTableParse | Enabled | A large number of structured revenue and frequency band usage tables exist in financial reports. Enabling this option preserves table structure and prevents chunking from destroying data integrity |
minerU_enabled | Set based on actual testing | Some satellite financial reports include specially formatted PDFs or encrypted attachments. Enabling minerU can improve parsing success rates |
UPLOAD_FILE_MAX_SIZE | 500 MB | Satellite financial reports may include multiple attachments such as satellite constellation deployment reports and frequency band filing documents, so larger file uploads must be allowed |
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 errors
- Issue: An error occurs when parsing the same CSV-format satellite communications financial report after a version upgrade. Cause: The new version updates CSV field validation rules and does not adapt to non-standard technical fields included in the financial report, such as
transponder_bandwidth_MHz. - Issue: Parsed chunk results lose frequency band unit information within tables. Cause: The
enableTableParseconfiguration is not enabled. The system automatically splits tables into plain text, causing units to separate from parameters. - Issue: Uploaded PDF-format financial reports cannot be directly passed to the large language model and must first go through the system's parsing process. Cause: No custom parsing node is configured. The default process first runs the system's built-in document parsing, and this step cannot be skipped directly.
How to confirm the configuration is set correctly
- Upload a standard quarterly satellite communications financial report PDF, and check if the parsed text retains complete unit information for technical parameters such as frequency band and orbital altitude.
- Test the chunking results of the same financial report with different
maxChunkSizevalues, and confirm that core business logic such as the revenue and cost of a specific frequency band is not split into different chunks. - After enabling
minerU_enabled, upload a specially formatted encrypted financial report document, and confirm that the parsing status shows success with no missing fields. - Adjust
UPLOAD_FILE_MAX_SIZEto 500 MB, upload a financial report compressed package containing multiple attachments, and confirm that the upload and parsing processes are not interrupted.
