US vs China Satellite Constellations: Starlink vs Beidou/G60
May 20, 2025
Satellite communications is undergoing a revolution led by Starlink. By 2025, SpaceX's Starlink has launched over 5,000 satellites, covering most regions of the globe. China is also accelerating the construction of its own satellite constellation system, including the Beidou navigation system and G60 satellite internet. The two systems have different functional positioning, technical paths, and strategic intentions.
I. Scale & Coverage
| Metric | Starlink | Beidou System | G60 Satellite Network |
|---|---|---|---|
| Satellite count | 5,000+ (42,000 planned) | 63 (completed) | 14,000 (planned) |
| Orbit altitude | 550 km | 21,500 km / 35,786 km | 500-11,000 km |
| Coverage | Global | Global | Global |
| Positioning accuracy | ~1 m (needs GPS) | 2-5 m | — |
| Communication bandwidth | 220Mbps+/user | Short message communication | Terahertz communication |
| Main function | Broadband internet | Navigation + timing + communication | Satellite internet |
Starlink is positioned around low-Earth orbit broadband internet access, targeting global consumer and enterprise markets. The Beidou system focuses on navigation and positioning while also incorporating communication functions, serving as China's comprehensive national positioning infrastructure. The G60 satellite network is China's version of 'Starlink,' positioned as the backbone of an integrated space-ground information network.
II. Technical Architecture Comparison
- Starlink: Single-layer LEO architecture, uses Ku/Ka bands, supports inter-satellite laser links
- Beidou: Three-layer architecture (MEO + GEO + IGSO)
- G60: Layered architecture (LEO + MEO), plans to use terahertz communication technology
- Inter-satellite links: Both Starlink and G60 support inter-satellite laser communication
III. Commercialization Progress
Starlink has achieved global commercial operations with over 5 million users and annual revenue exceeding $2 billion. Its advantages of low cost and high performance are disrupting the traditional satellite communications market. The Beidou system is widely used in both military and civilian domains, covering transportation, power, finance, and other industries. The G60 satellite network is still under construction and is expected to begin providing services in 2027.
| Dimension | Starlink | Beidou System | G60 Satellite Network |
|---|---|---|---|
| User count | 5 million+ | Hundreds of millions (application terminals) | Under construction |
| Annual revenue | $20B+ | Undisclosed | Expected operation in 2027 |
| Launch cadence | 40-50 per month | On-demand launch | Dense launches underway |
| Terminal price | $299+ | Free / low cost | To be determined |
| Competitive advantage | Low cost, wide coverage | Autonomous, military-civilian | Space-ground integration |
IV. Strategic Impact
The two major satellite constellation systems are not just commercial communication networks, but also core components of national space infrastructure. Starlink demonstrated its military application potential in the Russia-Ukraine conflict, while the Beidou system provides China with independent navigation and timing capabilities. With the completion of the G60 satellite network, China will have one of the largest satellite internet infrastructures in the world. Competition in space infrastructure will become an important dimension of 21st-century great power competition.
