Chang Guang JL1 Satellite Fleet News Scraper

Scrapes news and articles from Chang Guang Satellite Technology (长光卫星) — operators of the JL1 (吉林一号) constellation, the largest commercial high-resolution EO fleet in China with 100+ satellites in orbit.

This actor covers all five news channels on jl1.cn: company news, media coverage, announcements, industry trends, and application news. For each article it extracts the full text, publication date, and satellite metadata (name, sensor type, launch vehicle, resolution) where mentioned.

Use Cases

  • Track JL1 constellation growth: new satellite IOC, decommissioning, and fleet milestones
  • Monitor commissioning announcements for competitive GEOINT analysis (Maxar/Planet benchmarking)
  • Extract launch event data (vehicle, date, satellite name) for TLE-augmented fleet tracking
  • Feed news into maritime DA or agriculture monitoring competitive-intel pipelines
  • Research Chinese commercial EO market developments

Notes

  • The site uses Chrome UA detection. The actor uses core_crawler (impit Chrome fingerprint) which satisfies this automatically with no proxy required.
  • External media coverage articles (channel media_coverage) link to third-party sites. article_id will be null for these since no jl1.cn ID is present in the URL.
  • Satellite metadata fields are extracted from article body text via regex — present only in articles that explicitly mention satellite technical details.
  • The company news channel has approximately 179 pages (~895 articles). Scraping all channels without a maxItems cap may produce 3,000–5,000 articles.
