We offer a broad range of receiver options and subscription services, including a choice of two redundant satellite clock and orbit correction data messages:
C-NavC¹® or C-NavC²®. Each is simultaneously broadcast across the globe by Six Inmarsat geosynchronous satellites.
The new C-Nav5000 GNSS Receiver builds on the previous C-Nav3050 technology. It provides 5cm-level position accuracy, using the C-Nav Correction Service (CCS). Powered by the new Onyx GNSS Engine the C-Nav5000 is capable of tracking GPS, GLONASS, BeiDou, and Galileo. It has all-in-view parallel tracking with 252 channels for navigation, SBAS and 3 channels for CCS. Includes 4 serial ports, USB, and up to 8 Ethernet connections. With patented interference rejection and anti-jamming capabilities, and hardware capable of future enhancements, this will be a leading receiver well into the future.
Vector™ VS1000 GNSS Receiver
Oceaneering is an authorized reseller of the Vector VS1000, Hemisphere® GNSS’ premiere multi-GNSS, multi-frequency receiver designed specifically for the professional marine market. Providing precise heading, Athena RTK positioning, and full Atlas capability, its rugged design is compliant to IP67, MILSTD-810G, MIL-STD-202F, and IEC 60068-2 standards.
R330 GNSS Receiver
Oceaneering is an authorized reseller of the Hemipshere® R330 GNSS receiver–a full solution product in a compact enclosure. The R330 use the Hemisphere GNSS’ Eclipse™ platform and the latest GNSS patented technology. The R330 provides accurate positioning using several differential correction methods such as Athena™ RTK, Atlas® L-band corrections (Atlas Basic, H30, H10), Beacon, and SBAS. Patented Multifunction Application (MFA) firmware enables the R330 to smoothly transition between DGNSS systems.
The C-Mariner up-scalable ring laser gyro (RLG) system is based on technology developed at Honeywell Aerospace, with a proven track record of over 3.6 billion operational hours.
The C-Mariner system is optimized for integration with the C-Nav3050 receiver, and is upgradable to output heading, pitch, roll, heave, position, and velocity. It is a fully compliant inertial navigation system (INS).
The C-Nav1PPSI converter/combiner is a multi-function interface for GNSS receiver 1PPS signals. It has two opt-isolated 1PPS inputs, which are connected directly to the receiver's 1PPS outputs.
For high-integrity systems with dual GNSS receivers, the interface will "OR" the two TTL sources for output to peripherals that require a continuous 1PPS for time stamping. This output is maintained should either GNSS input fail.
Vector™ VS330 GNSS Receiver
Oceaneering is an authorized reseller of the Hemipshere® Vector VS330 GNSS receiver–a full solution product in a compact enclosure. The Vector VS330 uses all of the innovations in Hemisphere GNSS’ Eclipse™ Vector technology. Our optimized Eclipse Vector technology brings a series of new features to the Vector VS330 including heave, pitch, and roll output, and more robust positioning and heading performance.
The C-Nav Combiner enables the use of separate GNSS and L-band antennas. It is used in high-latitude operations where the low look angle of the separate L-band antenna enables reception of correction signals that is not possible with a standard integrated GNSS/L-band unit.
This combiner can be mounted on the mast or locally with the GNSS receiver.
Vector™ V500 GNSS Smart Antenna
Oceaneering is an authorized reseller of the Vector V500, Hemisphere® GNSS’ all-in-one multi- frequency, multi-GNSS smart antenna which provides RTK-level position and precise heading. This rugged design is sealed for the harshest environments and is a great solution for professional marine and other challenging applications.
The AD591 antenna is a GNSS antenna (ALIAD591) housed in hard anodized, dichromate, and nickel-acetate–sealed aluminum with a 4-mm GRP pressure-molded radome. It has > 95 dB of out-of-band-rejection of the Inmarsat uplink.
The integrated base GNSS antenna (PN: NAV82-001021-3001LF) tracks multiple signals. It is designed to reduce multipath error to provide better real-time kinematic (RTK) corrections to the rover network. It has excellent tracking performance and a stable phase center.
The antenna is listed in the NOAA GNSS Antenna Calibration tables as NCT-ANT3001B.
The airborne antenna (NAV82-001022-3001LF) tracks multiple signals and is designed to reduce multipath error to provide better RTK corrections to the rover network. It has excellent tracking performance and a stable phase center.
The antenna is listed in the NOAA GNSS Antenna Calibration tables as NCT-ANT3001A.
C-NaviGator III software is an intuitive touchscreen controller that provides real-time system accuracy and performance parameters for multiple GNSS receivers. The rugged and reliable wheelhouse-friendly display supports multiple NMEA inputs and outputs. It is fully compliant with the latest guidelines for GNSS positioning within the oil and gas industry per the International Association of Oil & Gas Producers and International Marine Contractors Association.
The C-Monitor application provides a graphical interface for supervising the operation and performance of one or more differential GNSS systems. It is compliant with the latest QA/QC guidelines for GNSS positioning within the oil and gas industry per the International Association of Oil & Gas Producers (IOGP) and the International Marine Contractors Association (IMCA).
The guidelines allow for pre-set user-defined alarm settings or limits, which can be set using the C-Monitor application.
C-Scape position monitoring and situational awareness software provides independent real-time monitoring of any dynamic positioning (DP) system. The simple, intuitive interface furnishes situational awareness to users during drillship, dive boat, remotely operated vehicle (ROV) vessel, and other operations by blending multiple sensors with map file overlays.
C-Tides is a worldwide tidal data software package that combines the exceptional vertical accuracy of the C-Nav3050 receiver with advanced ocean surface models to deliver real-time elevations relative to the mean sea surface (MSS) and EGM2008.
Two independent options are offered—an online package for real-time acquisition, and an offline package with post-processing and other advanced features. Accuracy is within accepted constituent limits to achieve IHO SP44 Order 1 or better.
 Subject to tidal regime limitation.
