GNSS罗盘
The GNSS Compass is a low cost all in one GNSS/INS navigation and heading solution. It provides accurate dual antenna GPS based heading that is not subject to magnetic interference and can maintain accurate heading during GNSS outages of up to 20 minutes. It features high accuracy RTK positioning and is plug and play with NMEA0183, NMEA2000 and Ethernet interfaces.
GNSS罗盘是低成本卫星导航/惯导一体化组合导航和航向解决方案。提供准确的双GPS天线航向，不受磁干扰影响，在GNSS中断后20分钟内保持准确度。特点是准确的RTK定位即插即用，兼容NMEA0183、NMEA2000协议，和以太网接口。
Fully Integrated Navigation 完全集成导航
The GNSS Compass is a fully integrated wheelmark certified GPS/INS navigation and heading solution. It contains a 9 axis IMU that is integrated with a dual antenna GNSS system with high performance antennas. It provides higher heading accuracy than magnetic systems and does not require any calibration or setup. The system is plug and play for NMEA0183 and NMEA2000 integrations, requiring no setup or configuration.
GNSS Compass是符合欧洲轮子标识（水上设备指令96/98/EC法规）的GPS/INS导航和航向解决方案。集成了9轴IMU、双天线GNSS系统，天线高性能。比磁罗经航向准确度高，不需要任何校准和设定，即插即用兼容NMEA0183和NMEA2000。
Performance and Interface Options 性能和接口选项
Four product variants are available to cater to every different application and budget. The low cost variant is an L1 only solution that is suitable for commercial vessel navigation while an L1/L2 variant meets the high accuracy requirements of surveying applications. It is also possible to choose between an NMEA0183/NMEA2000 interface and a power over ethernet interface for maximum flexibility. The Ethernet variant features NTP and PTP timing servers for precise time synchronization.
四种产品配置满足不同应用和预算。低配是L1单频适合商用船导航，L1/L2双频满足高准确度要求的测绘应用。此外，也提供NMEA0183/NMEA2000接口，或POE接口，以满足柔性需要。POE以太网接口能做NTP和PTP服务器高精度时间同步。
High Accuracy 8mm Positioning高准确度8毫米定位
The high accuracy variant supports L1/L2 RTK to deliver real time position accuracy of 8mm. Both the high accuracy and low cost variant support PPK (post processing) to deliver 8mm position accuracy using the Kinematica post processing software. Both variants support all of the current and future satellite navigation systems including GPS, GLONASS, GALILEO and BeiDou.
高准确度配置支持支持L1/L2 RTK实时位置准确度8mm。高准确度配置和经济型配置都支持 PPK后处理，通过Kinematica后处理软件提供8mm准确度。它们都支持四大导航卫星系统GPS, GLONASS,北斗和GALILEO。
Minimized Size, Weight and Price尺寸小型化、重量轻量化、低廉价格
The GNSS Compass dramatically reduces the size weight and cost of attaining a high accuracy position and heading solution. In addition the plug and play functionality of the device means that anyone can install it in minutes.
GNSS Compass大大缩小了尺寸、减轻了重量、降低了成本，还做到了高准确度定位和航向。此外，即插即用功能意味着任何人可以在几分钟内安装好设备。
应用
MARINE船舶
The GNSS Compass is ideal for all sorts of marine applications including racing yachts, commercial container vessels and recreational vessels. It features plug and play operation for NMEA0183 and NMEA2000 networks. It is wheelmark certified for use on commercial vessels.
GNSS Compass用于航海很理想，包括赛艇、商用集装箱船和悠闲船。即插即用操作于 NMEA0183和NMEA2000网络。轮子标识认证适合商用船舶。
AUTOMOTIVE汽车
The GNSS Compass is a convenient option for high accuracy position, velocity, roll, pitch and heading on ground vehicles. It can be installed in minutes and does not have any motion requirements to achieve its heading accuracy like other GPS/INS systems, which makes it suitable for slow moving survey vehicles. It is also a very valuable navigation sensor suite for autonomous vehicles.
GNSS Compass很方便给地面车辆提供高准确度定位、速度、横滚、俯仰和航向。能在几分钟内安装好，达到准确航向没有任何运动要求，不象其它GPS/INS系统适合低速测绘车辆需要调试。它也是对自动驾驶特别有价值的导航传感器套件。
MARINE SURVEYING海洋调查
For applications such as USBL underwater positioning, side-scan sonar, LBL and other marine surveying technologies the GNSS Compass brings performance at a revolutionary price. The plug and play operation allows for fast and easy setup. Advanced Navigation's Kinematica post-processing suite allows the data to be further enhanced after the survey.
对于诸如USBL超短基线水下定位、侧扫声纳、长基线定位和其它海洋调查技术，GNSS Compass带来了革命性的价格。即插即用操作可以快速和容易安装。AN的Kinematica后处理可以在测绘后增强数据准确度。
ANTENNA TARGETTING天线追踪系统
The GNSS Compass is an easy and low cost addition for high accuracy roll, pitch and heading in both stationary and dynamic antenna targetting applications.
GNSS Compass很容易低成本做高准确度横滚、俯仰和航向，不管是静态还是动态天线寻向应用。
