One Silicon Chip Photonics Builds a Navigation System for When the Satellites Go Dark

When a satellite signal winks out, the most critical question for an autonomous vehicle is not where it was, but where it is going. For the engineers and operators who rely on them, the failure of a global navigation satellite system (GNSS) is not a hypothetical. It is a known vulnerability, a point of failure that can be exploited by an adversary or simply lost in a tunnel, a canyon, or the deep sea. The standard response, an inertial measurement unit (IMU), is a stopgap. Its MEMS gyroscopes and accelerometers drift, accumulating error with every second of blind navigation. The clinical outcome, in this context, is mission failure.

One Silicon Chip Photonics (OSCP), a Montreal startup founded in 2015, is engineering a different kind of safety net. Its wedge is a photonic gyroscope, a chip-scale sensor that uses light rather than moving mechanical parts to measure rotation. The promise is a dramatic reduction in that drift error, buying precious minutes,or hours,of accurate navigation when the primary signal is gone. The company’s recent $6 million Series A, led by New Science Ventures, brings its total disclosed funding to approximately $11.4 million, capital earmarked to move its prototypes into production for defense, aerospace, and robotics customers [BetaKit, October 2026] [PRNewswire, 2024].

The photonic wedge in a MEMS world

OSCP’s product strategy is a graduated climb from established components toward its core innovation. Its entry point is the MK2M2, a tactical-grade MEMS IMU the size of a matchbox, designed for small drones and robotics [oscp.com/products/mk2m2, 2026]. The next step, the MK2E2, is where the photonics enter. This unit replaces the traditional MEMS gyroscope on the critical Z-axis (heading) with a photonic gyroscope, while keeping MEMS sensors for the other axes [newscienceventures.com, 2026]. The spec sheet claims a minimum in-run bias stability of 0.5 degrees per hour for the optical axis, an order-of-magnitude improvement over high-performance MEMS, with an angular random walk of 0.03 degrees per root hour [oscp.com/technology, 2026]. At the top of the line sits the MK2Z, a navigation-grade prototype aiming for bias stability below 0.01 degrees per hour [oscp.com/technology, 2026].

This architecture is not about building a wholly new navigation stack from scratch. It is about inserting a superior component into existing workflows. OSCP’s NavigationGate processing unit is designed to fuse data from its own IMUs with dual-antenna GNSS and other aiding sensors, outputting position, velocity, and attitude [devcuration.com, Unknown]. The company has also released open-source drivers for the popular ArduPilot autopilot platform and the ROS 2 framework, a clear nod to the developer and research communities that serve as a proving ground for autonomy [Investing.com, October 2026].

A founder forged in defense R&D

The technical ambition is rooted in the background of founder and CEO Kazem Zandi. He holds a PhD in engineering physics from Polytechnique Montréal and spent years as a senior optoelectronics engineer at Defence R&D Canada, the national military research agency [BetaKit, October 2026]. That tenure, coupled with a stint as a process engineer at Québec’s C2MI microelectronics hub, gave him a dual perspective on both the application need for resilient navigation and the manufacturing challenge of building it. Zandi holds 15 patents in advanced microsystems and integrated photonics, a portfolio that forms the foundational IP for OSCP’s sensors [BetaKit, October 2026]. The company’s advisory board includes Larry Coldren, a noted figure in photonic integrated circuits, suggesting deep technical validation [Cignal AI, July 2026].

OSCP’s funding history reflects a blend of venture confidence and non-dilutive support critical for capital-intensive hardware. The path to its Series A included a $1.2 million seed round led by 7percent Ventures and 2050 Capital, and a substantial $4.2 million in grants from Canadian agencies like Sustainable Development Technology Canada (SDTC) [PRNewswire, 2024]. The recent $6 million Series A, with continued participation from 2050 Capital and new investor Emerging Ventures, is tagged for production expansion in Montreal and commercializing next-generation sensors [BetaKit, October 2026].

Series A (2026)	$6 million	New Science Ventures	Production scale-up and next-gen product commercialization [BetaKit, October 2026]

The market of denied environments

The customer thesis extends beyond a niche technical sale. OSCP lists its target markets as defense, aerospace, robotics, heavy industry, space, maritime, and autonomous ground systems [Perplexity Sonar Pro Brief]. In each, the failure mode is the same: a loss of situational awareness when GNSS is jammed, spoofed, or physically blocked. Defense is the most obvious and demanding early adopter, where anti-access/area denial (A2/AD) strategies make GPS jamming a standard tactic. OSCP has tested a prototype with defense giant Thales and is a qualified supplier for the Canadian government’s Defence Drone Initiative Marketplace [Perplexity Sonar Pro Brief].

But the tailwinds are not purely military. As autonomy moves into industrial settings,autonomous trains in tunnels, drones for indoor inventory management, subsea robotics,the need for a reliable, continuous navigation solution grows. The commercial wedge, as CEO Zandi frames it, is “navigation continuity in environments where satellite navigation cannot be trusted” [PRNewswire, October 2026]. This frames the product not as a luxury, but as an enabling technology for autonomy to operate in the real, signal-hostile world.

Navigating the commercialization risk

The ambition is clear, but the path from prototype to product in deep tech is fraught with specific hurdles. OSCP must execute on three parallel fronts: manufacturing yield, customer qualification cycles, and competitive displacement.

• Manufacturing at scale. Photonic integrated circuits (PICs) are notoriously difficult to produce with high yield and consistent performance. The $6 million Series A is a meaningful war chest, but scaling a novel photonics process in-house requires precision capital expenditure. The company’s current hiring push for photonics, embedded systems, and sensor fusion roles signals this is a core focus [oscp.com/careers].
• The defense sales cycle. Landing a design-win with a prime contractor or a national defense program is a multi-year endeavor involving rigorous testing, certification, and often, geopolitical considerations. The Thales prototype test is a promising signal, but it is only a first step in a long journey [Perplexity Sonar Pro Brief].
• Incumbent and emerging competition. While no direct competitors are named in the sources, the inertial navigation market is served by established players like Honeywell, Northrop Grumman, and SBG Systems, who offer high-end fiber-optic gyroscopes (FOGs) and refined MEMS units. OSCP’s bet is that its chip-scale photonic approach can offer FOG-like performance in a smaller, more scalable form factor at a lower price point. Proving that value proposition against entrenched alternatives is a business development challenge as much as an engineering one.

The company’s answer appears to be a pragmatic, two-track market approach. By serving the accessible robotics and research market with open-source tools and lower-cost MEMS units, it can build revenue, community trust, and real-world validation data. Simultaneously, it can pursue the longer-cycle, higher-margin defense and aerospace deals with its photonic flagship products.

For the engineers integrating autonomy into drones, underwater vehicles, or next-generation aircraft, the current standard of care is a trade-off. They layer sensors, implement complex sensor-fusion algorithms, and often accept that operations must pause or limit scope when satellite signals fail. OSCP’s proposition is to extend that window of reliable operation, to turn a system’s failure point from a matter of seconds into one of minutes or hours. The patient population, in this case, is every autonomous platform operating beyond the reach of a clear sky. The next twelve months will be about moving from promising prototypes in a Montreal lab to hardened sensors on customer platforms, proving that its photonic light can indeed guide the way when the stars go out.
