Maritime Satellite Services: Complete Guide to Ship Connectivity & Communications

L-band MSS terminals, such as Inmarsat FleetBroadband and Iridium Certus, provide global coverage with compact antennas but limited data throughput. Ku-band VSAT (12–18 GHz) has been the maritime workhorse, Ka-band HTS (26–40 GHz) offers higher capacity, while C-band deployments are restricted near shore due to interference and large dish requirements. GEO satellites offer broad coverage with about 600 ms latency,…

Stock Market Today

  • Alphabet set to beat the market in 2026 but unlikely to replicate 2025 surge
    January 17, 2026, 3:21 PM EST. Alphabet, parent of Google, was a top performer in 2025 among the Magnificent Seven, a group of large tech names that surged last year. The unusually strong run may not repeat in 2026, but the stock could still beat the market. Key themes: Gemini, Alphabet's AI model, is winning enterprise adoption; Google Search remains a dominant cash cow, and AI-generated Overviews have helped keep traffic intact. Political risk from antitrust eased after a lighter penalty and no breakup was mandated, while Chrome and Android stay core to the business. A later monetization of AI could lift the multiple, though the near term remains uncertain. The stock hovered around $330 with a roughly $4 trillion market cap as of the latest session.
