FEATURES特点

Spatial FOG Dual 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 with low dynamics where single antenna systems struggle or any application where additional heading accuracy is required. An added benefit is the ability to accurately measure vehicle slip angle.

EXTREME INERTIAL PERFORMANCE卓越惯性性能

Spatial FOG Dual contains the KVH Industries 1750 fibre optic gyroscope (FOG) IMU, which provides extremely accurate inertial data far beyond the best MEMS technology available. This allows Spatial FOG Dual to acheive very high accuracies and dead reckon without GNSS for extended periods of time. Despite the high accuracy FOG IMU, Spatial FOG Dual has a very competitive price tag that is lower than many MEMS systems on the market.

RTK GNSS RECEIVER支持实时动态差分

Spatial FOG Dual contains a dual frequency Trimble 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 and BeiDou. It also supports the Omnistar service for hassle free high accuracy positioning. Spatial FOG Dual supports both real time RTK positioning and logging of raw satellite data for kinematic post-processing.

ADVANCED FILTER先进滤波技术

Spatial FOG Dual 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.

HOT START热启动

Spatial FOG Dual contains a next generation battery backup system that allows it to hot start inertial navigation from its last position in 2 seconds and obtain a GNSS fix in approximately 3 seconds. The battery backup system lasts for the lifetime of the product and will provide backup for 48 hours without power. Advanced Navigation's Spatial series are the only GNSS/INS in the world to provide hot start inertial navigation.

RELIABILITY高可靠性

Spatial FOG Dual has been designed from the ground up for mission critical control applications where reliability is very important. It is built on top of a safety oriented real time operating system and all software is designed and tested to safety standards with fault tolerance in place. 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. Spatial FOG Dual contains a backup MEMS IMU, which it can seamlessly fall back to should the primary IMU fail.

HIGH UPDATE RATE高数据更新率

Spatial FOG Dual's internal filter runs at 1000Hz and data can also be output at this rate over high speed RS232 or RS422. This allows for control of dynamically unstable platforms.

PERIPHERALS外挂附件

Spatial FOG Dual features two general purpose input output pins and two auxiliary RS232/RS422 ports that support an extensive number of peripherals. Including odometer based input for ground vehicles, DVLs and USBLs for underwater navigation, NMEA input/output and more. For an integration fee, custom peripheral devices can be added.

APPLICATIONS应用

MARINE SURVEYING海洋调查

Spatial FOG Dual is ideal for marine surveying applications, providing all the reference data required in a single unit. It provides a very high accuracy source of real time roll, pitch and heading as well as RTK accuracy positioning ideal for referencing subsea points. It features a revolutionary tightly coupled heave filter that provides heave accuracy surpassing most post processed heave systems. It also supports Omnistar for enhanced accuracy positioning offshore.

LAND SURVEYING大地测量

Spatial FOG Dual's high accuracy roll, pitch and heading make it well suited for surveying applications. It supports RTK which allows it to provide dramatically enhanced positioning accuracy over standard GPS with positioning accuracy of 8mm. 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 output of RINEX raw satellite data for post processing.

HELICOPTERS直升机

Spatial FOG Dual 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. Spatial FOG Dual is able to provide very high accuracy heading under all conditions whether stationary or moving and through all levels of magnetic interference.

ANTENNA TARGETTING天线追踪系统

In both stationary and moving antenna applications, Spatial FOG Dual provides a high accuracy source of roll, pitch and heading that is ideal for antenna targetting control. Its ability to provide continuously reliable data through extended GPS outages and interference means that systems can maintain very high uptimes.

MOTORSPORT赛车

Spatial FOG Dual 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. Spatial FOG Dual’s high vibration tolerance and dynamic range means there are no concerns about engine or road vibration. Spatial FOG Dual also supports data output to data acquisition systems such as Dewesoft products.

ROBOTICS机器人

Spatial FOG Dual’s accurate orientation data allows for stabilization of robotic systems and its position, velocity and acceleration data can be used for robot navigation. Spatial FOG Dual’s high update rate allows it to control dynamically unstable platforms and its focus on safety and reliability provides for piece of mind.

Base station radio modem RTK corrections: Base station radio modem RTK corrections require two additional pieces of hardware, these are the base station and the radio modem receiver. The base station is setup at a fixed location and transmits corrections to the radio modem receiver that is connected to the mobile Spatial FOG unit. The radio modem receiver and Spatial FOG unit must remain within range of the base station to receive these corrections, typically this range is approximately 20km. We recommend Trimble R8s RTK base station.
