ROS 52-24922-AT06 Navigator TI 3KM Underwater Monochrome Camera

The Remote Ocean Systems (ROS) 52-24922-AT06 Navigator TI is a precision-engineered, ultra-low-light monochrome video camera built for subsea tooling, inspection-class ROVs, and deep-ocean observation platforms. Housed in Grade 5 (6Al-4V) titanium, this unit is pressure-rated for continuous operational deployment down to 3,000 meters (approx. 9,842 ft / 300 bar hydrostatic pressure).

Operating on the EIA RS-170 (525 line / 60 Hz) standard, the Navigator TI delivers 570 horizontal TV lines through a high-sensitivity 1/2-inch interline transfer CCD. The camera features dedicated internal Long Line Compensation (LOC/LLA) circuitry, allowing transmission of composite video signals across extended ROV umbilical cables up to several thousand feet without high-frequency attenuation, smearing, or loss of synchronizing pulses. With an extreme faceplate sensitivity reaching 3.4 × 10¯4 the Navigator serves as a high-reliability, solid-state replacement for fragile, high-voltage silicon intensified target (SIT) subsea cameras.

Frequently Asked Questions

What is the difference between the ROS Navigator 52-24922-AT06 and standard underwater cameras?

The Navigator 52-24922-AT06 is an extreme low-light monochrome camera utilizing a 1/2-inch CCD lux sensitivity, engineered explicitly for abyssal zones where color sensors fail due to total light absorption. The “TI” designation specifies a 6Al-4V titanium housing rated for 3,000 meters depth, while “AT06” denotes an EIA RS-170 output format with integrated long-cable transmission amplifiers.

Can the Navigator TI operate continuously in air without overheating?

While the unit can operate in air for pre-dive testing and alignment (-20°C to +60°C), prolonged bench testing at ambient air temperatures should be limited to avoid thermal buildup on the internal sensor board. Full thermal dissipation is optimized for seawater convection.

What does the internal LOC / LLA circuitry do?

LOC (Line Output Compensation) and LLA (Long Line Amplifier) equalize the high-frequency signal losses inherent in long subsea cables. This prevents the video signal from blurring, losing vertical/horizontal sync, or dropping contrast when transmitted through thousands of meters of ROV umbilical tether.

Is this unit compatible with PAL/CCIR European shipboard video systems?

The 52-24922-AT06 is an EIA RS-170 (525 line / 60 Hz) NTSC-standard monochrome unit. For vessels or ROV consoles operating strictly on 625 line / 50 Hz CCIR standards, an active video converter is required, or the CCIR variant (ROS 52-24923 series) should be deployed.

How is the unit packaged to ensure safe international transit?

Units are degreased, O-ring sealed, terminal-capped with protective dust hoods, wrapped in moisture-barrier anti-static film, and securely housed in custom impact-resistant cases to prevent shock damage during courier transit.
