Daily Tech & GNSS News Digest - April 20, 2026

Google is making its boldest move yet against Nvidia’s chip dominance as the AI hardware wars enter a new phase. Meanwhile, the U.S. Space Force pulled the plug on one of the most expensive GPS programs in history, signaling a dramatic reset for satellite navigation infrastructure.

Google Eyes New Inference Chips in Partnership With Marvell, Challenging Nvidia

Alphabet’s Google is in talks with Marvell Technology to develop two new chips aimed at speeding up AI inference — the process of running trained models. Bloomberg reports that one chip would be a memory processing unit designed to work alongside Google’s tensor processing units (TPUs), while the other would be a new TPU built specifically for inference workloads.

The move deepens Google’s push to position its custom silicon as a viable alternative to Nvidia’s widely used GPUs. TPU sales have become a significant growth driver for Google Cloud, and the company has landed high-profile customers including Meta, Anthropic, and Apple. The news sent Marvell shares surging while rival Broadcom fell, as investors recalibrated which chipmakers stand to benefit from the next wave of custom AI silicon.

Cerebras Files for IPO at Up to $25 Billion Valuation

AI chipmaker Cerebras Systems filed its S-1 registration statement with the SEC on April 17, reviving an offering it pulled last year over regulatory concerns tied to UAE-based investor G42. The company is targeting a Nasdaq listing under ticker CBRS at a $22–$25 billion valuation, seeking to raise approximately $2 billion.

Cerebras reported $510 million in 2025 revenue and has secured a deal to provide up to 750 megawatts of computing power to OpenAI through 2028, valued at over $20 billion. Amazon Web Services is also reportedly planning to deploy Cerebras chips alongside its own Trainium processors later this year. The listing, planned for mid-May, would make Cerebras the largest pure-play AI chip IPO to date.

Blue Origin’s New Glenn Grounded After Placing Satellite in Wrong Orbit

Blue Origin made history on April 19 by reusing a New Glenn first-stage booster for the first time — but the milestone was overshadowed by a critical mission failure. The upper stage placed AST SpaceMobile’s BlueBird 7 satellite into an orbit too low to sustain operations, and the satellite will now have to be de-orbited and left to burn up in the atmosphere.

AST SpaceMobile shares dropped sharply, though the company said the loss is covered by insurance and it still plans to have roughly 45 satellites in its constellation by year-end. The FAA classified the event as a mishap, grounding New Glenn pending an investigation. It was the rocket’s third launch overall and its first customer payload failure.

Space Force Kills $6.3 Billion GPS Ground Control Program, Awards Lockheed Martin Alternative

The U.S. Space Force formally terminated its contract with RTX for the Next-Generation Operational Control System (OCX) on April 20, ending one of the most troubled programs in GPS history. Originally awarded to Raytheon in 2010 at roughly $1.5 billion with a 2016 delivery target, the program ballooned to $6.27 billion and triggered a Nunn-McCurdy breach for cost overruns.

Officials cited “insurmountable” challenges discovered during integrated testing with the broader GPS enterprise. The OCX system was intended to provide modernized command and control for GPS III satellites with enhanced cybersecurity, jamming resistance, and support for the military’s M-Code signal. The Space Force has instead awarded Lockheed Martin a $105 million contract to continue modernizing the existing Architecture Evolution Plan (AEP) ground segment — a pragmatic pivot that acknowledges a decade of failed development while keeping GPS operations running.

Net Insight Leads ESA-Backed Project on Next-Generation PNT Technology

Sweden-based Net Insight has been awarded a development project through the European Space Agency’s Navigation Innovation and Support Program (NAVISP), co-funded by the Swedish National Space Agency. The project aims to develop positioning, navigation, and timing technology that complements existing GNSS systems like GPS and Galileo, addressing growing concerns about jamming and spoofing threats to critical infrastructure.

The work focuses on ensuring reliable time synchronization for telecommunications, 5G networks, transportation, and energy systems — sectors increasingly vulnerable to GNSS disruption. As NAVISP enters its tenth year in 2026, the program is expanding activities with new funding secured at the ESA Ministerial Council, with NAVISP Industry Days planned later this year to engage the broader European PNT ecosystem.

Key Takeaways

The AI chip war goes custom: Google’s Marvell partnership and Cerebras’ IPO filing signal that the semiconductor industry is fragmenting beyond Nvidia’s GPU monoculture, with inference-specific and wafer-scale architectures competing for the next phase of AI infrastructure spending.
GPS modernization hits reset: The Space Force’s cancellation of the $6.3 billion OCX program after 16 years of development is a stark reminder that even the most critical national infrastructure programs can fail — and that pragmatic alternatives often beat ambitious overhauls.
Space launch reliability remains elusive: Blue Origin’s New Glenn booster reuse was a genuine achievement, but the satellite deployment failure and subsequent FAA grounding underscore that reliable orbital delivery is still the hardest part of the rocket business.
