What This Category’s Data Looks Like
The data for satellite communications smart due diligence reports primarily comes from communication link logs collected by commercial satellite ground stations, real-time data from spectrum monitoring systems, and orbit maintenance archives publicly released by satellite operators. Data updates follow a near-real-time rhythm: core link status is refreshed every 5 minutes, while orbit parameters and spectrum occupancy data are updated daily. Each individual due diligence document includes fields such as satellite ID, beam coverage latitude and longitude range, real-time link delay, peak bandwidth occupancy rate, and spectrum interference alarm records. Delay is measured in milliseconds, bandwidth in Mbps, and orbit height in kilometers.
Constraints for HTTP Interfaces and External Systems
The near-real-time update rhythm of satellite communications due diligence data requires external interface call intervals to not exceed 5 minutes, otherwise the latest link status cannot be retrieved. The structured multi-field document structure requires that HTTP interface return formats be compatible with standard JSON, and field names must strictly align with preset fields in the due diligence report template. Differentiated update frequencies for some fields require configuring incremental pull logic to avoid invalid requests and bandwidth consumption from full pulls. The large data volume per individual document requires that single request return volumes follow pagination rules to prevent single request timeouts.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
EXTERNAL_API_TIMEOUT | 300 seconds | Adapts to occasional delays in satellite communication links and covers the response cycles of most long-running requests |
HTTP_RETRY_MAX_TIMES | 3 times | Addresses temporary fluctuations in satellite ground station interfaces and reduces the probability of single request failure |
INCREMENTAL_PULL_SWITCH | Enabled | Matches the near-real-time update rhythm of satellite communication data and reduces invalid requests from full pulls |
FIELD_MAPPING_RULE | Map in the order of satellite ID, link delay, bandwidth occupancy | Aligns with the field display logic of the due diligence report template |
API_BATCH_SIZE | 20 items/request | Balances single request data volume and interface load, and adapts to the field scale of single satellite communication documents |
The parameter values provided on this page are general recommendations for starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis, and it is recommended to test against your own samples before finalizing settings.
Three Common Misconfigurations
- The symptom is slow response when a locally deployed FastGPT calls the satellite communications API, while direct curl calls run at normal speed. The cause is that the
EXTERNAL_API_TIMEOUTconfiguration value for FastGPT is set too small, which does not adapt to the delay characteristics of satellite communication links, leading to early termination of requests and retries, which increases cumulative delay. - The symptom is empty or incorrectly formatted satellite communications data fields in generated due diligence reports. The cause is failure to strictly follow the
FIELD_MAPPING_RULEconfiguration, resulting in incorrect mapping of interface return fields to the report template. - The symptom is the interface returning status code
429 Too Many Requests. The cause is thatINCREMENTAL_PULL_SWITCHis not enabled, and full pulls with too short call intervals exceed the interface rate limiting threshold of the satellite communications service provider.
How to Verify Proper Configuration
- Execute a curl command to call the target satellite communications API, compare the FastGPT configured interface address, request headers, and request body to confirm they fully match the configuration items.
- Review the FastGPT external interface call logs to confirm that request intervals comply with the pull rules corresponding to
INCREMENTAL_PULL_SWITCH, and there is no high-frequency full pull behavior. - Trigger a due diligence report generation task, review the satellite communications data fields in the generated results to confirm that the field names match the mapping rules of
FIELD_MAPPING_RULE. - Simulate an abnormal status code return from the interface, confirm that FastGPT executes the retry logic according to the
HTTP_RETRY_MAX_TIMESconfiguration, and the number of retries matches the preset rules.
