OSCP is proud to introduce MK2Z, a new ultra-low-drift photonic IMU engineered for platforms that cannot afford to lose their inertial reference when GPS is degraded, denied, or intermittent.

MK2Z: ultra-low drift, mission-ready

MK2Z delivers class-leading stability with a gyro bias instability of just 0.015 deg per hour, enabling precise dead reckoning and long-duration navigation without frequent GNSS updates. This level of bias performance dramatically slows error growth over time, giving integrators a much more stable foundation for their navigation and control stacks in real-world missions.

Built on OSCP’s patented photonic gyroscope technology, MK2Z combines integrated photonic gyros with MEMS accelerometers to track all 6 axes of motion accurately and reliably. With no moving parts, the underlying photonic sensor architecture is inherently robust, offering low noise, high reliability, and strong resilience to vibration, temperature variation, and electromagnetic interference.

Built for GPS-challenged environments

Like the rest of OSCP’s IMU portfolio, MK2Z is designed for GPS-denied and GPS-challenged environments where traditional IMUs force a trade-off between performance, size, and cost. Target applications include:

  • Small and medium UAVs that must maintain stable flight and accurate positioning through GNSS outages or spoofing events.

  • Autonomous ground and rail systems that need reliable inertial data in tunnels, urban canyons, and industrial sites.

  • Robotics, mapping, and inspection platforms operating indoors or around heavy infrastructure where GNSS is unreliable.

OSCP’s integrated photonics approach has demonstrated that high-performance inertial sensing can be delivered in smaller, lighter, and more power-efficient form factors, helping system designers meet tight SWaP-C budgets without sacrificing navigation quality.

Photonic technology advantage

OSCP’s photonic gyroscopes leverage the Sagnac effect on a photonic integrated circuit to detect rotation with high precision and low bias drift. Compared to conventional MEMS-only IMUs, this architecture offers reduced noise, improved long-term stability, and immunity to many environmental stressors, including EMI and harsh temperature conditions.

By tightly integrating photonic gyroscopes and accelerometers on a chip-scale platform, OSCP’s sensors can achieve performance levels previously associated with larger, more complex inertial systems - but in a compact, scalable package suitable for volume manufacturing.

Availability and next steps

MK2Z extends OSCP’s MK2 family, complementing existing 11‑DOF IMUs and GNSS-integrated units to give integrators multiple performance and system architecture options. Engineering samples and integration support are available for qualified programs in UAVs, robotics, autonomous vehicles, and defense and aerospace platforms.
