Gridbots Falcon

Gyro Stabilised Gimbal for 1 kg to 10 kg Optical Payloads

Gridbots Falcon is a precision gyro stabilised optical platform that holds a mounted sensor on target while the host vehicle pitches, rolls, vibrates and turns. Inertial rate sensing, direct-drive torque motors and a closed-loop servo running at high bandwidth cancel base motion before it ever reaches the optical line of sight.

The Falcon family spans four frame sizes. The compact F1 holds line of sight to 50 µrad RMS with payloads up to 1 kg; the heavy-lift F10 carries up to 10 kg of sensor mass and holds 150 µrad RMS. Every model shares the same servo core, command protocol and mechanical interface, so a payload developed on one frame moves to another without software change.

Falcon accepts any combination of day camera, cooled or uncooled thermal imager, laser range finder, laser designator, spotter scope or SWIR module inside its payload envelope. It ships as an open stabilised gimbal for integrators, or pre-populated with a Gridbots sensor suite for turnkey surveillance, naval observation, airborne survey and vehicle-mounted sighting roles.

Common Servo Core

The Falcon Model Range

Four frames, one servo architecture. Stabilisation accuracy trades against carried mass: the lighter the payload and the smaller the inertia, the tighter the loop holds. Pick the frame by payload mass first, then confirm the stabilisation figure meets the mission's angular budget.

Stabilisation figures are RMS residual line-of-sight error measured at maximum rated payload on a 6-DOF motion table under the reference sea-state / cross-country profile. Lighter payloads improve the figure.

Features of the Falcon Stabilised Platform

Stabilisation Performance

Residual line-of-sight error is what decides whether a long-focal-length sensor produces a usable image from a moving platform. At 50 µrad, the Falcon F1 holds a target inside a single detector pixel of a 90× zoom camera at 2 km. The tables and charts below show measured residual error against base-motion severity and payload mass.

Values are RMS residual line-of-sight error at maximum rated payload for each frame. Quoted headline accuracy corresponds to the cross-country reference profile.

Payload Integration

The payload bay is an open mechanical volume with a bolt pattern, power rails and data lanes brought through the slip ring. Mount a sensor, declare its mass and centre of gravity, and the platform runs an inertia auto-tune on the next power-up. No servo re-tuning by hand, and no controller firmware change when moving a payload between frames.

Falcon: Gyro Stabilised Optical Platform & Stabilised Gimbal

The Gridbots Falcon is a four-axis gyro stabilised optical platform built for sensors that have to stay on target from a moving host. As a stabilised gimbal it uses direct-drive torque motors, absolute encoders and fibre-optic rate gyros to reject base motion, delivering line-of-sight stabilisation from 50 µrad RMS on the compact F1 frame through to 150 µrad RMS on the heavy-lift F10. Payload capacity spans 1 kg to 10 kg, so the same platform family covers a single lightweight day camera on a UAV, a fused EO/IR and laser range finder suite on a vehicle mast, and a large-aperture long-range telescope on a coastal or naval pedestal. Continuous 360° azimuth, geo-pointing, slew-to-cue and a shared control protocol across every frame make the Falcon a straightforward stabilised camera platform for integrators building surveillance, observation, survey and sighting systems.
