- Geospatial Data for Investment Analysis: Data collected by Earth observation satellites, part of larger satellite networks, can provide valuable insights for commodity trading, real estate analysis, and environmental, social, and governance (ESG) investing. The space economy, including satellite activities, continues to grow globally, demonstrating its increasing importance to the broader economy.8 The Federal Reserve Bank of San Francisco has noted the increasing economic impact of the space sector, which includes satellite networks.6, 7
Limitations and Criticisms
Despite their numerous advantages, satellite networks face several limitations and criticisms:
- Latency: While LEO constellations significantly reduce it, traditional geostationary orbit satellites inherently have higher latency due to their distance from Earth, which can be a drawback for ultra-low-latency financial applications like high-frequency trading.
- Cost: The development, launch, and maintenance of satellite networks involve substantial capital expenditure, making them a significant investment. This can translate to higher service costs compared to terrestrial alternatives in densely populated areas.
- Cybersecurity Risks: Satellite communication systems are vulnerable to various cyber threats, including jamming, spoofing, and denial-of-service attacks, which could disrupt critical financial data transmission. Cybersecurity and Infrastructure Security Agency (CISA) and the FBI have issued advisories warning of potential threats to satellite communication networks, highlighting the importance of robust security measures.2, 3, 4, 5
- Space Debris: The increasing number of satellites in orbit contributes to space debris, posing collision risks that could damage operational satellites and affect the long-term sustainability of satellite-based services.1
- Regulatory Complexity: Operating satellite networks involves navigating complex international regulations and spectrum allocation challenges, which can affect deployment timelines and operational flexibility. Effective risk management strategies are essential to mitigate these issues.
Satellite Networks vs. Terrestrial Networks
The primary distinction between satellite networks and terrestrial networks lies in their infrastructure and transmission medium. Terrestrial networks rely on ground-based infrastructure, such as fiber optic cables, copper wires, and cellular towers, to transmit data. This typically offers very high bandwidth and extremely low latency over shorter distances. However, their reach is limited by geographical barriers and the cost of laying extensive physical infrastructure, particularly in remote or challenging terrains.
Conversely, satellite networks use orbiting satellites to relay signals across vast distances, providing global coverage, including areas inaccessible to terrestrial networks. While historically associated with higher latency due to the signal's travel distance, newer low Earth orbit (LEO) constellations are significantly reducing this gap. The choice between these two network types often depends on factors like required speed, geographic coverage, cost-effectiveness for a given location, and the need for network diversification and resilience.
