Comtech’s SLM-5650B Becomes First Sovereign‑Certified Modem to Operate on SES’s O3b mPOWER MEO Constellation

Comtech’s defense‑grade SLM‑5650B modem has been certified to operate on SES’s O3b mPOWER medium‑Earth orbit satellite constellation, becoming the first sovereign‑certified terminal cleared for service on the network. The certification enables secure, government‑grade connectivity over SES’s high‑throughput MEO broadband platform.

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).
