What the SQ-330Q is
Inside the Laser Designator Pods the SQ-330Q covers a specific job: the largest pod we build — a 330 mm turret and 22 kg of payload capacity for heavy platforms. It speaks the same control protocol and video format as the rest of the family, so payloads can be exchanged between missions on the same aircraft.
Core capabilities
The features that decide whether imagery is usable in the air, in the order an integrator usually checks them.
- Gyro-stabilised line of sight
Direct-drive brushless axes with high-resolution encoding hold the line of sight to ≤ 100 μrad (1σ), and the stabilisation loop reacts at ≥ 60°/s angular velocity so imagery stays steady in turbulence and rotor wash.
- Continuous optical zoom
The visible channel is 1920 × 1080, 30x zoom 10 – 300 mm. Continuous zoom keeps a wide search field and a tight identification field available without changing lenses, with autofocus and electronic image stabilisation at sub-pixel level.
- Uncooled thermal channel
Dual 640 × 512, 300 mm + continuous zoom 15 – 330 mm, long-wave infrared with NETD ≤ 40 mK, boresighted to the visible channel so both sensors point at the same target with no re-alignment in flight.
- Laser rangefinding
The rangefinder measures ≥ 15 km at an eye-safe 1535 nm, which turns video into a distance measurement and feeds the target coordinate calculation.
- Onboard AI detection
Person, vehicle, vessel and aircraft detection runs on the payload itself, with no dependency on the data link and no frames sent to a ground station for processing.
- Multi-target tracking
Lock and follow up to 20 targets at once, with anti-occlusion logic that re-acquires a target after it passes behind terrain, a mast or another object.
Stabilisation and mechanical design
Two axes, direct drive
Pitch and yaw are driven directly by brushless motors with high-resolution encoding, which keeps the line of sight steady without gear backlash. The loop is specified at ≥ 60°/s angular velocity and holds the line of sight to ≤ 100 μrad (1σ).
22 kg in Φ330 × 420 mm
The complete head weighs 22 kg and measures Φ330 × 420 mm, with 11–28 VDC input and power consumption of 100 W / 600 W. That envelope lets heavy fixed-wing platforms, helicopters and maritime patrol aircraft carry the payload without a bespoke mount.
On the aircraft
Mounting, cable routing and vibration isolation are agreed with the platform integrator, so the payload drops into an existing airframe interface instead of needing a bespoke mount.
Multi-sensor payload
Configured as EO plus IR plus LRF plus laser designator. Each channel is boresighted to the others, so one target sits in the same place on every screen.
EO / visible
1920 × 1080, 30x zoom 10 – 300 mm
Detection 10.6 km person / 25 km vehicle.
Thermal / IR
Dual 640 × 512, 300 mm + continuous zoom 15 – 330 mm
Detection 6.7 km person / 22.7 km vehicle.
Laser rangefinder
≥ 15 km
Eye-safe 1535 nm, feeding target coordinates.
Channel detail
A sensor specification on its own rarely answers the operational question, so each channel is described here with the distance it actually supports.
EO / visible
The visible channel is specified at 1920 × 1080, 30x zoom 10 – 300 mm. Detection distances for the visible channel are quoted at 10.6 km person / 25 km vehicle using the standard 1.7 m person and 2.3 m vehicle targets; recognition and identification distances are shorter and appear in the datasheet.
Thermal / IR
The thermal channel is Dual 640 × 512, 300 mm + continuous zoom 15 – 330 mm, uncooled long-wave infrared with NETD ≤ 40 mK. Thermal detection is quoted at 6.7 km person / 22.7 km vehicle. Performance does not depend on daylight, which is what makes the channel useful for night operations and for scenes obscured by smoke or dust.
Laser rangefinder
The laser rangefinder measures ≥ 15 km at an eye-safe 1535 nm. Range readings feed the target coordinate calculation, so the ground station receives a georeferenced position instead of a range bar in the video.
Detection and tracking at the edge
Onboard AI module
The onboard module detects people, vehicles, vessels and aircraft and hands a target to the tracker for a stable lock. Because processing happens at the edge, latency is low and nothing leaves the aircraft unless you choose to transmit it.
What that means in the air
The operator sees a boxed target and a lock that survives occlusion rather than a raw feed. Because the module is common across the family, tracking behaviour does not change when the payload changes.
Tracking demonstration
Targets are boxed automatically as they appear, and the lock is held on the selected target even when it passes behind an obstruction.
Integration
One control protocol across the family
Every head in the range speaks the same control set, so moving from a two-axis to a three-axis payload, or adding a laser rangefinder, does not change the aircraft-side integration. The protocol document and video pipeline notes are supplied with the first unit.
Video, control and power
Video is carried as Ethernet in H.264 or H.265. The gimbal is controlled over RS-422, RS-232 or TTL with SBUS and MAVLink supported on the aircraft side, and power input is 11–28 VDC. Recording is handled on board, so the file exists even if the link drops.
Interface protocol document, video pipeline description and outline drawing are supplied with the first unit — ask the engineering team if you need them earlier for evaluation.

Mounting, interfaces and environment
Airframe integration is the part of a payload programme that is easiest to get wrong, so these are the numbers engineers ask for first. Everything below applies to the SQ-330Q.
Mechanical interface
The head mounts on a quick-release interface with a vibration-isolated gimbal base, and adapter plates are available for OEM airframes that do not share our bolt pattern. Mass and envelope are the catalogue limits for this head, so the aircraft-side budget can be checked before a prototype is built.
Electrical and data interface
Power, control and video are separated so the head can be flown from most autopilots: 11–28 VDC input, serial control on RS-422 / RS-232 / TTL, and video over Ethernet. On-board recording keeps the imagery even if the downlink drops.

| Envelope | ≤Φ330 × 420 mm |
| Power consumption | 100 W / 600 W |
| Input voltage | 11–28 VDC |

Where the SQ-330Q is used
Three mission profiles that match this weight class and sensor set.
- Maritime and border patrol
Long-range identification over water, where the operator sees a contact long before a vessel can be reached.
- Long-range identification
Narrow fields of view and long-range ranging are what turn a small contact into an identified object.
- Unmanned helicopter ISR
A heavier turret on an unmanned rotorcraft, sharing the same control protocol as the smaller heads.
Other heads in the range
Every model shares the same control protocol, video pipeline and AI module, so moving between them does not change the aircraft-side integration.

Questions engineers ask about the SQ-330Q
Does the SQ-330Q include AI detection and tracking?
Yes. Person, vehicle, vessel and aircraft detection plus multi-target tracking run on the payload itself, so they keep working when the data link degrades, and on-board recording keeps the imagery as well.
Are a datasheet and a dimension drawing available?
Yes — the datasheet, outline drawing and interface document for the SQ-330Q are supplied on request, together with the alignment and test data for the unit you receive.
Is a larger or a smaller head a better fit?
If the identification range in the requirement is longer than this configuration covers, the next step in the family is a heavier turret with a longer focal length and a larger aperture. If the aircraft is weight-limited, a lighter head normally keeps endurance.
Which sensors does the SQ-330Q carry?
The configuration is EO plus IR plus LRF plus laser designator: a visible channel at 1920 × 1080, 30x zoom 10 – 300 mm, a thermal channel at Dual 640 × 512, 300 mm + continuous zoom 15 – 330 mm, a laser rangefinder measuring ≥ 15 km.
What are the order terms for the SQ-330Q?
One unit for a stock configuration, custom builds from 100 units. A head held in stock ships from inventory, so the lead time is transit rather than a production slot; payment is by T/T with the schedule on the quotation, and the warranty is one year from delivery with support from our own engineers online.
Designed and manufactured by HITS
Optics, servo hardware, stabilisation firmware and the AI tracking module are developed in house, and every unit is assembled, calibrated and environmentally tested on our own line before it ships.
