Montréal-based OSCP has announced the MK2Z-3, an inertial measurement unit under development that can incorporate photonic gyroscopes on one, two, or three axes. The company’s October 27 announcement specifies a package under one kilogram and smaller than one liter, with samples planned for 2027.
The design extends OSCP’s MK2Z prototype, which uses a photonic gyroscope on the Z axis. Offering additional photonic axes in the same enclosure lets equipment manufacturers select a configuration without changing the basic package.
OSCP targets gyroscope bias stability of 0.01 degrees per hour or better. This is a development target, rather than a reported flight-test measurement or finalized production specification.
Gyroscopes support a spacecraft’s ability to track its orientation when external references are unavailable. OSCP identifies small satellites, landers, launch vehicles, re-entry capsules, and planetary rovers among the intended applications.
The MK2Z-3 retains RS-422 or CAN-FD interfaces used by existing customers. Keeping those connections allows an upgrade in sensing configuration without requiring an entirely new integration approach. The next announced delivery step is shipment of development samples in 2027.
