Briefing

What Hype is tracking

  • The SLM‑5650B is the first sovereign‑certified modem cleared for use on the O3b mPOWER network, giving governments a validated terminal option for secure MEO links — important as SES grows its MEO capability (see recent Falcon 9 deployments and commissioning of new O3b mPOWER satellites: https://hype.aero/?story=ce2d4ee9-3f47-4ab3-92a4-4234f79d3fce).
  • Certification arrives after SES expanded O3b mPOWER capacity with additional satellite deliveries, increasing the practical reach and throughput available to certified terminals (context on recent satellite deliveries: https://hype.aero/?story=7b396f6a-b88a-4951-9914-cdb358185251).
  • A defence‑grade, sovereign‑certified modem from a US supplier strengthens the MILSATCOM ecosystem and complements parallel sovereign-capacity initiatives such as national defence-focused satellite programs (related GovSat‑2 procurement context: https://hype.aero/?story=dd68329e-2326-4561-b5cd-140e5339fe16).
