Spatial is a ruggedized miniature GPS aided inertial navigation system and AHRS that provides accurate position, velocity, acceleration
and orientation under the most demanding conditions. It combines temperature calibrated accelerometers, gyroscopes, magnetometers and a pressure sensor with an advanced GNSS receiver. These are coupled in a sophisticated fusion algorithm to deliver accurate and reliable navigation and orientation.
Calibrated Dynamic Ranging Sensors
Spatial contains very high performance MEMs inertial sensors. 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.
Multi Constellation RTK 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. Spatial's GNSS receiver features L1 RTK which can provide positioning accuracy of 2cm and also supports kinematic post-processing accuracy of 1cm.
Spatial contains Advanced Navigation's revolutionary sensor fusion filter. The filter is more intelligent than a 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'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.
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 48 hours without power. Advanced Navigation's Spatial series are the only GNSS/INS in the world to provide hot start inertial navigation.
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.
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.
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.
Application: ROBOTICS, MOTORSPORT, HUMAN MOVEMENT, EXTREME SPORTS, TRACKING AND SECURITY.
Spatial's high accuracy roll, pitch and heading make it well suited for surveying applications. It supports L1 RTK which gives it significantly enhanced positioning accuracy of 2cm. 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. Spatial also supports kinematic post-processing providing positioning accuracy of 1cm.
UNMANNED AERIAL VEHICLES
Spatial is very popular on unmanned aerial vehicles. Its high accuracy orientation allows it to be used both for control and georeferencing. It supports a range of pitot tubes and air data units which allows it to maintain high accuracy positioning for hours without GPS. It supports both SBAS and ground transmitted differential corrections for increased GPS positional accuracy. It's low size, weight and power consumption allows for easy integration into even the smallest UAVs.
Spatial’s accurate orientation data allows for stabilization of robotic systems and its position, velocity and acceleration data can be used for robot navigation. Spatial’s high update rate allows it to control dynamically unstable platforms and its focus on safety and reliability provides for piece of mind.
Spatial is ideal for use in marine applications providing accurate positioning, heading, heel, trim and heave. Its rugged design stands up to tough conditions at sea. Its magnetic heading is calibrated for hard and soft iron using an advanced ellipsoid algorithm and can provide both true heading and magnetic heading using its built in world magnetic model.
Spatial 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’s high vibration tolerance and dynamic range means there are no concerns about engine or road vibration. Spatial also supports data output to data acquisition systems such as Dewesoft products.
TRACKING AND SECURITY
Spatial’s GNSS RAIM satellite verification, high sensitivity and multiple constellations make it difficult for thieves to spoof. Even if GNSS is lost, Spatial can continue to accurately navigate on its other sensors indefinitely when a vehicle odometer input is attached. Its backup memory means that cutting the power will not lose its position either. This makes it an excellent choice for tracking and security where it is nearly impossible for thieves to circumvent.
