Talking Points

Recent interactions between the hosts and their guests.

5G is Not a Destination: Adapting to the NTN Landscape with Comtech's Daniel Gizinski
Q: What opportunities do you see for NTN services in the near term, and where should operators focus their initial efforts?
Leverage NTN as a fast, reliable fallback and onboarding mechanism, emphasize direct-to-device and Ka-band VSAT deployments in high-demand sectors like oil & gas, energy, and logistics, and ensure service provisioning is streamlined to reduce the burden on end customers.
5G is Not a Destination: Adapting to the NTN Landscape with Comtech's Daniel Gizinski
Q: The evolution of satellite being incorporated into 3GPP standards has been a key issue; what practical steps should operators prioritize?
Prioritize a customer-centric view, focus on flexibility to adapt to changing standards, and architect systems that can evolve with ongoing 3GPP releases, ensuring interoperability and gradual migration from legacy to NTN-enabled capabilities.
Building Exact AI for High-Stakes Space Missions With PiLogic CEO Johannes Waldstein
Q: What does the path toward automation look like in practice?
A step-by-step journey toward trusted autonomy starts with automating low-risk decisions, ensuring verifiability and reversibility by humans, and gradually expanding automation to higher-stakes decisions as confidence and testing grow.
Building Exact AI for High-Stakes Space Missions With PiLogic CEO Johannes Waldstein
Q: What are the compute requirements for running this AI on satellites?
The approach is designed to be highly compute-efficient, with models pushed to space operating in megabytes, running on simple CPUs, and sometimes on devices as small as a Raspberry Pi, with optional GPU acceleration for more demanding tasks like sensor fusion.
Building Exact AI for High-Stakes Space Missions With PiLogic CEO Johannes Waldstein
Q: How did you connect with the other co-founders and identify a unique opportunity in space for this technology?
The co-founders were connected through long-term professional and personal networks; their backgrounds in aerospace engineering, advertising data platforms, and probabilistic/inference work converged on a space-ready inference engine that extends beyond traditional rules and thresholds.
