More Apache 3 Pro information

See the [ Datasheet ] for additional details.

3.44' long x 0.55' wide x 1.28 high; 61 lbs. with batteries. Can be transported in a small vehicle and deployed by a single operator.

3-hour operation at 5 MPH on 2 batteries, quick charging with 2 extra batteries allows nearly continuous operation if shore power is available for charging.

Unlike other USV's, the Apache 3 Pro has no external wires, attachment brackets, external GNSS receivers and other sensors mounted on high poles. All connections are hull-internal. The camera has a 355° unobstructed view other than the radio antennas, there are no receiver masts in any direction.

The Apache 3 Pro's internal wiring is fully dressed and protected. There are no unsheathed wires to snag.

A suitable RTK base or network correction source is required. An [ i83 ] or [ iBase ] with a copy of [ LandStar8 ] is a perfect companion device.

The Apache 3 Pro is not a mad-science project with cables going from transducers mounted on afterthought brackets attached to the hull. This is a well-engineered, 4th generation product where all the transducers, motor wiring, cameras, radar, antennas are designed into the hull. The internal wiring is dressed and protected for continuous real-world use.

Echo Sounder

The D270 sounder is temperature compensated to improve accuracy.

Sounding range: 0.5 to 650 feet (ideal conditions)

Sounding accuracy: 0.03 feet + 0.1% * Depth, at 100' depth = 0.13'

Frequency: 200 kHz

IMU and GNSS

The internal high-speed, high-accuracy IMU is used to correct for vessel attitude (pitch and roll):

The IMU also provides loss of GNSS lock real-time navigation when running under bridges.

Combined with dual-GNSS receivers for heading there is no need for an electronic compass.

Dual, full constellation RTK receivers with IMU enhancement provide 0.3" position and 0.2° heading accuracy.

Motor

The recessed motor helps operation in aquatic vegetation while reducing draft. High-speed, high-torque 7,200 rpm brushless DC motors reach 6 meter/second (12 MPH) with quick acceleration. Over-speed mitigation extends motor life when operating in weeds and fouling plants.

Motors have internal wiring so there are no cables on the exterior of the hull.

Balanced power supply system

Dual packs allow hot swapping. Discharges batteries equally to lower cell temperature and stress.

Obstacle avoidance

Millimeter wave radar allows automatic obstacle avoidance with a 120-foot range. A bottom tracking algorithm issues a shoal alert when the Apache encounters very shallow water.

Double hull, IP67 rated hatch, reduced penetrations, higher stability hull design increases vessel security.

Auto-return for low battery and loss of telemetry and RC control.

Comparing to the competition

Consider these items when comparing to the competition:

• Lighter weight, smaller size, reduced height allows easier transportation and single operator deployment.
• Faster speed, longer run time.
• Dual GNSS receivers for heading.
• Integrated IMU.
• 4G LTE cellular backhaul.
• Data storage redundancy: internal and controller.
• Clean design without external mechanical brackets, cables and equipment boxes.
• 65 lb. payload capacity.
• Extremely shallow 4" draft.
• Known pricing, spare part availability, rentals and charters.
