Advanced Navigation and KVH Industries have announced their new Spatial FOG GNSS/INS. Spatial FOG is a ruggedized GNSS aided inertial navigation system and AHRS that provides accurate position, velocity, acceleration and orientation under the most demanding conditions.
It combines the new KVH Industries 1750 fibre optic gyroscopes based inertial measurement unit with magnetometers, a pressure sensor and a dual frequency RTK GNSS receiver. These are coupled in a sophisticated fusion algorithm to deliver highly accurate and reliable navigation and orientation.
Spatial FOG contains a dual frequency RTK GNSS receiver that provides 1cm accuracy positioning and supports all of the current and future satellite navigation systems including GPS, GLONASS, GALILEO and COMPASS.
A next generation memory backup system allows Spatial FOG to hot start inertial navigation from its last position in 2 seconds and obtain a GNSS fix in as little as 3 seconds. The memory backup system lasts for the lifetime of the product and will provide backup for 24 hours without power.
Spatial FOG's internal filter runs at 1000Hz and data can also output at this rate over high speed RS232 or RS422. This allows for control of dynamically unstable platforms. Spatial FOG is also highly tolerant to both shock and vibration thanks to the outstanding performance of the KVH 1750 IMU design and advanced filtering.
Spatial FOG supports a wide range of peripherals including odometers, external GNSS receivers, DVLs, USBLs and NMEA devices. It also supports both industry standard NMEA output and a binary protocol.
With breakthrough performance, size, and flexibility in one package, Spatial FOG is easily integrated into retrofits or new designs.
