SATELLITE COMMUNICATIONS BRIEF · 2026
NASA updates small-spacecraft communications state of the art for 2026
NASA's 2026 Small Spacecraft Technology report updates RF and free-space optical communications technology and highlights the performance and pointing tradeoffs that accompany higher-frequency, wider-bandwidth links.
Engineering significance
- Bandwidth, antenna gain, pointing, atmospheric/propagation effects, terminal availability and link margin must be treated as a system trade.
- Commercial satellite connectivity decisions should distinguish consumer service claims from enterprise requirements for resilience, integration, support and service-level evidence.
- PROFENG calculators remain screening tools; mission or safety-critical links require project-specific communications engineering.
