The manufacturers website about the Spatial:

Calibrated Dynamic Ranging Sensors
Spatial contains 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 unit spends 8 hours in our specially built rotating temperature chamber.

Advanced Filter
Spatial contains Advanced Navigation’s revolutionary new 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
Spatial 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 24 hours without power. Spatial is the first GNSS/INS in the world to provide hot start navigation.

High Update Rate
Spatial’s internal filter runs at 1000Hz and data can also be output at this rate over high speed RS232. This allows for control of dynamically unstable platforms. Spatial is also highly tolerant of dynamic movement and vibration with a very advanced custom navigation filter.

Multi Constellation GNSS
Spatial’s next generation GNSS receiver supports all of the current and future satellite navigation systems including GPS, GLONASS, GALILEO and BeiDou. These additional satellite constellations allow Spatial to provide accurate position and velocity data in environments where GPS only units can’t, such as urban canyons and indoors. When Spatial can’t get a satellite fix, it continues to navigate using inertial navigation.

Miniature Rugged Enclosure
Spatial’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.

Reliability
Spatial 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.

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