Features
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 1 cm 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.
Applications
MARINE SURVEYING
Certus Evo is well suited for marine surveying applications, providing all the reference data required in a single unit. Its heading is more accurate than high end gyrocompasses costing ten times the price and is continuously reliable unlike GPS compass systems. It features a revolutionary tightly coupled heave filter that provides heave accuracy surpassing most FOG systems. It also supports kinematic post processing with Advanced Navigation's Kinematica post processing software for maximum accuracy results.
LAND SURVEYING
Certus Evo's high accuracy roll, pitch and heading make it well suited for surveying applications. It offers RTK (for free) which allows it to provide dramatically enhanced positioning accuracy over standard GPS with positioning accuracy of 1 cm. The system supports connection of a high resolution wheel speed sensor or odometer which allows it to maintain accurate data through GPS outages and continue surveys through tunnels and other areas where GPS signals are not available. It also supports kinematic post processing with Advanced Navigation's Kinematica post processing software.
HELICOPTERS
Certus Evo is ideal for use in helicopters where high levels of magnetic interference make magnetic heading unusable. In this application, single antenna GNSS/INS systems can have issues resolving the heading due to the 3D movement and stationary hovering of the platform. Certus Evo is able to provide very high accuracy heading under all conditions whether stationary or moving and through all levels of magnetic interference.
ANTENNA TARGETING
In both stationary and moving antenna applications, Certus Evo provides a high accuracy source of roll, pitch and heading that is ideal for antenna targeting control. Its ability to provide continuously reliable data through extended GPS outages and interference means that systems can maintain very high uptimes.
MOTORSPORT
Certus Evo is an excellent tool for performance measurement in motorsport. From the velocity and orientation data, slip, oversteer and understeer can be calculated. The velocity and acceleration data can be used to calculate improvements to braking and accelerating. Position can be used to determine the deviation from the optimum track position. Certus Evo’s high vibration tolerance and dynamic range means there are no concerns about engine or road vibration. Certus Evo also supports data output to data acquisition systems such as Dewesoft products.
ROBOTICS
Certus Evo’s accurate orientation data allows for stabilization of robotic systems and its position, velocity and acceleration data can be used for robot navigation. Certus Evo’s high update rate allows it to control dynamically unstable platforms and its focus on safety and reliability provides for piece of mind.
