What the data for this category looks like
Data sources for satellite communications research reports include public reports from aerospace industry consulting institutions, financial research reports from securities firms covering the communications sector, and monthly operational documents from satellite operators. Updates follow a monthly regular cadence, with temporary supplementary updates for major events such as satellite launches and frequency band approvals.
Document structure includes modules such as title, issuing institution, release date, core technical parameters, business analysis, and risk warnings. Core fields include coverage frequency band (unit: GHz), single satellite communication bandwidth (unit: Mbps), and number of in-orbit satellites (unit: satellites). The length of individual documents varies widely. It is recommended to confirm values based on statistics or actual measurements using your own samples.
What constraints these characteristics impose on HTTP interfaces and external systems
Decentralized data sources require interfaces to support unified access and format conversion across multiple data sources. This avoids parameter confusion in financial analysis caused by field differences between reports from different sources.
The monthly update cadence requires external systems to support both scheduled synchronous pull and event-triggered temporary updates. This covers both regular industry research reports and content from sudden policy events.
The fixed format of professional parameter fields requires interfaces to retain original units and field names when returning data. Arbitrary modification or stripping will affect the accuracy of financial quantitative analysis.
The long-document characteristic requires interfaces to support paged transmission and long-text parsing. This avoids exceeding transmission or processing limits with a single request, which impacts the timeliness of financial decision-making.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxRetrievalNum | Top 10-15 entries | Satellite communications research reports have lengthy individual content. Excessive recall will exceed the context window, leading to truncated interface responses |
similarityThreshold | 0.75-0.85 | Satellite communications industry terminology is highly specialized. A threshold that is too low will introduce irrelevant reports, while a threshold that is too high will miss content from relevant niche segments |
apiRequestTimeout | 30-60 seconds | Research report parsing and data pulling require processing long texts. An overly short timeout will interrupt incomplete requests |
syncUpdateInterval | Once daily | Regular research reports are updated monthly. Daily synchronization can cover newly added event-based reports |
allowedResponseFields | Title, issuing institution, release date, coverage frequency band, single satellite bandwidth | Core fields of satellite communications research reports are fixed. Limiting returned fields can reduce network transmission overhead |
fileUploadSizeLimit | 100 MB | Individual research report PDF/Word files typically do not exceed 100 MB. Exceeding this limit will cause upload failures |
The parameter values provided on this page are common recommended starting points 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 confirm after actual testing using your own samples.
Three common errors
- A
413 Request Entity Too Largestatus code is returned when calling the interface. Cause: ThefileUploadSizeLimitconfiguration was not adjusted, and the uploaded research report file exceeds the default limit. - A
429 Too Many Requestsstatus code appears during concurrent interface calls. Cause: No interface concurrency limit was configured, and the default rate limit cannot support simultaneous requests from multiple users. - The interface returns a parsing failure after uploading a research report file. Cause: An insufficiently long
PARSE_FILE_TIMEOUT_SECONDSwas set, and long-text research report parsing was interrupted before completion.
How to confirm correct configuration
- Send an HTTP retrieval request carrying satellite communications frequency band keywords, and verify that the returned result fields include the content preset in
allowedResponseFields. - Upload a standard-format satellite communications research report file, and confirm that the interface returns a parsing success status identifier.
- Send multiple concurrent retrieval requests, and confirm that no
429 Too Many Requestsor504 Gateway Timeoutrelated errors appear. - Adjust the value of
similarityThreshold, and verify that the relevance of the returned results matches business requirements.
