Advanced Navigation Certus Evo

Certus Evo is an ultra high accuracy GNSS/INS that provides accurate position, velocity, acceleration and orientation under the most demanding conditions. It combines ultra high accuracy temperature calibrated MEMS accelerometers, gyroscopes, magnetometers and a pressure sensor with a dual antenna RTK GNSS receiver. These are coupled in a sophisticated fusion algorithm to deliver accurate and reliable navigation and orientation.

ULTRA HIGH ACCURACY MEMS SENSORS

Certus Evo features the highest accuracy MEMS accelerometers and gyroscopes currently available. Certus Evo’s inertial performance exceeds some FOG IMUs and is up to 10x smaller and cheaper. Certus Evo is put through Advanced Navigation’s intensive calibration process to provide consistently accurate data over an extended temperature range of -40°C to 85°C. As part of this calibration, every high accuracy GNSS/INS spends 22 hours in our specially built rotating temperature chamber.

ADVANCED FILTER

Certus Evo contains Advanced Navigation’s revolutionary sensor fusion filter. The filter is more intelligent than the typical extended kalman filter and is able to extract significantly more information from the data by making use of human inspired artificial intelligence. It was designed for control applications and has a high level of health monitoring and instability prevention to ensure stable and reliable data.

MULTI CONSTELLATION RTK GNSS

Certus Evo contains a dual frequency RTK GNSS receiver that provides up to 8mm accuracy positioning and supports all of the current and future satellite navigation systems, including GPS, GLONASS, GALILEO, BeiDou and QZSS.

DUAL ANTENNA HEADING

Certus Evo features dual antenna moving baseline RTK. This allows it to provide highly accurate heading while both stationary and moving. It is an excellent choice for applications where magnetic heading is not usable due to interference or where additional accuracy is required. An added benefit is the ability to accurately measure vehicle slip angle.

MULTI-PROTOCOLS AND INTERFACES

Certus Evo features multiple interfaces including Ethernet, CAN, RS232, RS422 and GPIOs. Certus supports all the industry standard protocols including NMEA 0183, NMEA 2000, TSS, PASHR, Simrad as well as a wide variety of proprietary protocols.

RELIABILITY

Certus Evo’s precision marine grade aluminium enclosure is waterproof and dirtproof to the IP67 standard and shockproof to 2000g, allowing it to be used in the most extreme conditions. A sophisticated venting system allows the unit to measure air pressure whilst keeping water out. Its minimal size, weight and power requirements allow for easy integration into almost any system. The hardware is protected from reverse polarity, overvoltage, surges, static and short circuits on all external interfaces. The GNSS contains RAIM, which excludes both malfunctioning, and tampered satellite signals.

TIME SYNCHRONISATION

Certus Evo contains a GNSS disciplined oscillator that can act as the primary time source within a distributed time system, enabling access to ultra-accurate system time using PTP or NTP network time sync. Certus Evo also has a high-accuracy 1PPS and frequency output.

EMBEDDED USER INTERFACE

Certus Evo features a rich, responsive embedded web interface that provides full access to all of the device’s internal functions and data. 

INTERNAL DATA LOGGING

Certus Evo contains 256GB internal storage, allowing the user to log up to 1 year of navigation data without a requirement for any external systems or accessories.
