Groundwave Weekly — Jul 16, 2026

The theme this week is uncomfortable but clear: the world's communications infrastructure is being treated less like neutral plumbing and more like contested territory. The U.S. and Venezuela are jamming GPS across the Caribbean hard enough that one in five commercial flights has hit navigation trouble; the FCC just finished the biggest overhaul of submarine cable rules in a generation and drew a hard line around Chinese gear at the beachhead; and Germany's deadline to purge Huawei from its 5G core is now six months out and real. Underneath all of it, a quiet pattern: militaries and regulators alike have started building — and funding — their way out of dependence on a single point of failure.

The Caribbean isn't a simulation. It's live airspace, real passengers, and GPS that can't be trusted. An escalating standoff between the United States and Venezuela has led both militaries to jam satellite navigation signals in the region, putting air and sea traffic at greater risk of collision or accident, per the San Juan Daily Star's account of the NYT reporting. At least some U.S. warships deployed to the Caribbean have been jamming GPS in their vicinity, according to an analysis of Stanford University data and a U.S. official; in response, forces loyal to Venezuelan President Nicolás Maduro have jammed signals around critical infrastructure — military bases, oil refineries, power plants — according to an analysis by Spire Global cited in the RNTF summary of the NYT story.

The civilian toll is measurable. At least one in five flights in the Caribbean has experienced GPS navigation problems since early September, per Stanford's GPS Lab. Pilots from Caribbean Airlines and Copa Airlines have told air traffic controllers their systems were jammed, forcing them to request radar guidance for landings.

This is the real-world version of the positioning, navigation, and timing (PNT) resilience problem that defense analysts have theorized about for years. When two militaries both jam GPS defensively, the electromagnetic spillover doesn't respect flight-information-region boundaries. The observable signal to watch is regulatory: if the FAA issues formal NOTAMs (notices to air missions) requiring backup navigation on Caribbean routes, that's the moment PNT-denied airspace management stops being a Pentagon white paper and becomes standard civil-aviation procedure.

Submarine cables — the fiber lines on the ocean floor that carry virtually all transcontinental internet, financial, and AI traffic — have been governed by rules written before the smartphone existed. At its June 25 open meeting, the FCC voted unanimously to approve a Second Report and Order modernizing that framework, and the implementation details are landing this week. (The FCC Just Rewrote the Rules for the Cables That Carry 99% of the Internet)

The most consequential piece is what the FCC is now regulating for the first time: the shore-end gear. The Commission established a new licensing requirement for owners of submarine line terminal equipment (SLTE) — the systems that terminate a cable and connect it to U.S. terrestrial networks — describing SLTE as one of the most critical and vulnerable components of the whole architecture. Any entity controlled by a designated foreign adversary, or on the FCC's Covered List — Huawei, ZTE, HMN Tech — faces a standard of presumptive denial, per Submarine Networks' analysis. Trusted U.S. operators, meanwhile, get a fast-track "glide path" tuned for the infrastructure demands of AI.

The fast-track-for-friends, presumptive-denial-for-adversaries structure is a reordering of who gets to build the physical backbone of the internet. The failure mode is a compliance bottleneck — legacy consortium cables running mixed-vendor architectures now have to audit their landing-station hardware. Watch cable-landing-equipment manufacturing lead times in Q4 as those audits pile up; that's where the friction shows first.

The end of 2026 is roughly six months out, and Germany's three big operators — Deutsche Telekom, Vodafone, and Telefónica — are in the final stretch of a politically fraught, technically brutal, and expensive rip-and-replace. They've agreed to remove Huawei and ZTE components from their 5G "core networks" — the internet-connected control centers that route traffic and authenticate subscribers — by the end of 2026, with access and transport networks (towers, transmission lines) to follow by end-2029, as CNN Business first reported when the deal was struck.

Reuters reported this week on the phase-out's progress. Germany is widely seen as a laggard on the EU's 5G security measures; operators have resisted Berlin's push, and Huawei has rejected what it calls the "politicisation" of cybersecurity, per U.S. News.

Hitting the core-network deadline on schedule would be the most concrete step any major European economy has taken to decouple its comms infrastructure from Chinese vendors. Quietly missing it would signal that the political will to pay the real cost of decoupling has a ceiling. Ericsson and Nokia are the primary beneficiaries; their European order books are the tell.

Amazon's Kuiper — its answer to Starlink — is racing a regulatory clock. The company must deploy a minimum number of satellites by a fixed FCC deadline or risk its license, and per KeepTrack's analysis this week, that means launching 231 satellites in roughly 90 days.

That's an aggressive manifest. SpaceX can batch-launch Starlink at pace because it owns both the rocket (Falcon 9) and the satellite factory. Amazon is juggling multiple launch providers — United Launch Alliance, its own Blue Origin New Glenn — while still ramping production. (The FCC Draws a Spectrum Line Between Satellites)

If it works, Kuiper becomes a credible commercial rival to Starlink for the first time, with real implications for maritime, aviation, and enterprise broadband. If it slips, the FCC could grant an extension (it has before) or force a renegotiated license. The observable signal is the launch cadence over the next 30 days — if the manifest stalls, the 90-day window is effectively closed, and you'll see it in FCC filings before you see it in a press release.

The Pentagon's Space Development Agency is back to launching its Transport Layer after a months-long technical pause. Breaking Defense reported Tuesday that SDA plans to launch another 21 York-built satellites following a "strategic pause" prompted by issues in the first 42 spacecraft launched last year. Seven more Tranche 1 launches remain, toward an architecture of 158 satellites spanning transport, missile tracking, and fire control. (SDA Restarts Its Orbital Data Mesh With 21 More Satellites)

The point of the program isn't metal in orbit — it's a resilient, low-latency communications mesh in low Earth orbit (LEO) that keeps passing data even when parts of it are contested or fail. (SDA Restarts Its Orbital Data Mesh With 21 More Satellites)

Launching satellites is the easy part. The hard part is optical cross-links, routing, timing, and performance under stress — that's where the real program risk lives. The signal to watch: if SDA starts talking less about launch cadence and more about on-orbit link reliability, they've reached the part that actually determines whether Golden Dome's networking layer works. (SDA Restarts Its Orbital Data Mesh With 21 More Satellites)

This week: a Venezuelan power plant humming inside its own GPS dead zone while a Copa pilot asks a controller to talk him down; a Taiwanese island rerouted around a shipwreck onto microwave radio older than half its users; and a DARPA optical clock riding a warship through the Pacific just to prove it can keep time without asking a satellite for permission. The tell of the week isn't the jamming — it's that the Pentagon handed $49.7 million to Canyon Consulting to build the escape hatch, and almost nobody noticed. Signal's up, trust is down, and somewhere a spectrum lawyer is quietly becoming the most important person in the room. (SDA Restarts Its Orbital Data Mesh With 21 More Satellites)
