The manufacturers website about the Spatial Dual:

Dual Antenna Heading
Spatial 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 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.

Calibrated Dynamic Ranging Sensors
Spatial Dual contains some of the highest performance MEMs inertial sensors currently on the market. These are put through Advanced Navigation’s intensive calibration process to increase their performance further still and provide consistently accurate data over an extended temperature range of -40°C to 85°C. Advanced Navigation’s custom calibration process is the only full sensor calibration that can provide dynamic ranging, allowing the user to select a sensor range for high accuracy or high accelerations on the fly. As part of this calibration, every Spatial Dual unit spends 8 hours in our specially built rotating temperature chamber.

RTK GNSS Receiver
Spatial Dual contains a triple 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.

Advanced Filter
Spatial 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.

Miniature Rugged Enclosure
Spatial Dual’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.

Hot Start
Spatial Dual contains a next generation battery backup system that allows it to hot start inertial navigation from its last position in 500 milliseconds 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.

Spatial 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 mind. 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 Dual features four general purpose input output pins that support an extensive number of peripherals. Including odometer and wheel encoder inputs for ground vehicles, external RTK GPS systems, NMEA input/output, event triggers and more. For an integration fee, custom peripheral devices can be added.
