Model 3500

This robust model offers comprehensive imaging and tracking capabilities, and user applications. It includes high resolution sonar, both side scan and forward scan. The forward scan sonar includes flexible capabilities to meet specific project needs, which include: set to 360 degree continuous rotation, set to sector which is 180 degrees, or set the sector size in 3 degree increments. The Nova+ skids provide for extra payload, as well as three different configurations. The basic configuration is for full range imaging. Removal of the forward scan sonar system allows for two additional configurations: Side scan and internal camera imaging, or removal of all sonar for basic inspections and surveys. Like all Nova Ray® ROVs, this model can accommodate user defined add-on technology. Mission critical inspection and tracking projects will stay on course with this portable workhorse.

Key features include:

Side scan and forward scan sonar
3 configurations for multiple tasks
Removable nose extension with viewing dome replacement
Nova+ skids for extra payload
Proprietary Command and Control software with interval upgrades
Fully digital onboard electronics
Two, 1/4 hp thrusters

Category Standard Feature Nova Ray® ROV Model 3500 Specifications
Depth Depth Rating 305meters (1,000 feet).
Currents Stability in Strong Currents Arcuate wing design counters destabilizing effects of cable drag. Results in faster, more stable performance in currents with less cable.
Maneuverability Dual Operation Mode Can be towed or use thruster power in strong currents. See Speed for knots.
  Speed Up to 9 knots in currents under tow. With thrusters: 4 to 6 knots (1/4 or 1/3hp respectively)
  Cable to Depth Ratio Under tow, Nova Ray® provides deeper operation with less cable than other Underwater Towed Vehicles (UTV). Nova Ray® can operate up to 70% deeper than conventional UTV systems using the same cable length. Under tow, operates at a ratio of 2.38:1. With thrusters, the Nova Ray® can reduce the ratio to 2:1. With less cable, the Nova Ray® system is lighter, smaller and easy to deploy anywhere in the world on a rapid response basis.
  Thrusters DC brushless rare earth motors. Two (1 port; 1 starboard) magnetic drive; 1/4hp standard with 150 volts DC. Optional 1/3 hp. Propellers and Thruster Guards (HMW plastic): 75mm for 1/4 hp., and 90 mm for 1/3 hp.
  Control Surfaces Rudder provides directional control; two elevons provide vertical positioning (depth control).
