Stay on course when GNSS goes dark.
A chip-scale silicon photonic gyroscope that measures rotation with light. Jammers and spoofers attack satellite signals. This sensor never listens to them, so your UAV holds its heading from inside the airframe.
From silicon to sky.
Watch the module assemble bottom-up, drop top-down into a UAV navigation bay and fly. Then see the service teardown. Drag the timeline or pick a chapter.
Two UAVs. One jammer.
Only one comes back.
Both aircraft fly the same mission into an area of GNSS jamming and spoofing. UAV-1 navigates on the Lorentis photonic gyroscope. UAV-2 trusts GNSS only.

Mission log
Simulation for illustration. Not flight-test data. Performance figures are available to qualified partners under NDA.
Inside the gimbal: a steady eye, even under spoofing.
Mounted on the camera payload, the gyroscope senses every gust and vibration and keeps the line of sight locked on target. When a spoofer attacks GNSS, the inertial reference catches the mismatch and rejects the false position. Your geo-tags stay true.
Measuring rotation with light.
Light is split into two beams that travel around a photonic ring in opposite directions. When the platform rotates, one beam arrives a little later than the other. This is the Sagnac effect. The phase shift moves the interference fringes at the detector, and the shift is proportional to the rotation rate.

Chip-scale
The full optical path sits on one silicon photonic chip, small enough for gimbals, micro-UAVs and munition-class platforms.
No moving parts
Solid-state optical sensing. Nothing spins or wears, and it resists the vibration that degrades mechanical gyros.
Jam & spoof resilient
Inertial measurement needs no external signal, so RF jamming has nothing to attack. It gives the reference that exposes GNSS spoofing.
FPGA-native readout
Lorentis designs the readout electronics in-house on FPGA, from detector signal to calibrated rate output.
Built for volume
Designed for semiconductor manufacturing, bringing optical-gyro class sensing to cost-sensitive platforms.
Mission-ready integration
Standard digital interfaces for autopilots, gimbals and INS, with Lorentis integration support.
