The NTN Sanity Check: Is Satellite IoT Actually Production-Ready?

In mid-April 2026, Nordic Semiconductor released v1.0.0 of their NTN modem firmware for the nRF9151, a "1.0" tag that's supposed to mean ready for production. So we put it to the test. This is the NTN Sanity Check: an end-to-end satellite IoT deployment built from off-the-shelf parts, designed to answer the three questions every builder actually asks — does it work, what does it cost, and what does it draw? The setup: – Nordic nRF9151 SiP running the v1.0.0 NTN modem firmware – Actinius Icarus development board – Kyocera AVX NTN antenna – Monogoto SIM with native Skylo integration – TagoIO IoT platform with UDP server What you'll see in the video: 00:00 — Why we built this 00:33 — The hardware setup 01:11 — Building the NTN application 02:32 — The moment of truth 04:10 — Conclusion Built with Monogoto, TagoIO, Actinius, and Kyocera AVX.
