Advanced Navigation Releases Spatial Dual GNSS/INS Antenna

Spatial Dual contains the Trimble BD982 GNSS receiver, which is a triple frequency dual antenna RTK GNSS receiver. Using dual frequency moving baseline RTK, Spatial Dual is able to provide heading accuracy of less than 0.1 degrees using it’s dual antennas. The dual antenna heading works while both stationary and moving and allows for very accurate heading in both slow moving and 3D vehicles, where equivalent single antenna systems must rely on magnetic heading. An additional benefit of the dual antennas is the ability to measure slip angle to within 0.2 degrees.

Spatial Dual supports all of the current and future satellite systems, including GPS, GLONASS, GALILEO and BeiDou. In addition, Spatial Dual supports RTK for centimetre positional accuracy and the recent Omnistar G2 network for hassle free 10 centimetre accuracy.

Spatial Dual provides position, velocity and orientation at rates up to 1000Hz for highly dynamic applications. When Spatial Dual loses a GNSS fix it continues to navigate using dead reckoning inertial navigation to provide seamless navigation data through tunnels and other outage situations.

Spatial Dual is housed in a precision marine grade aluminium enclosure that is waterproof and dirtproof to the IP67 standard and shockproof to 2000g, allowing it to be used in tough conditions.

Spatial Dual supports a wide range of peripherals including odometers and wheel speed sensors for ground vehicle navigation, DVLs and USBLs for underwater navigation and many other external sensors. It supports both industry standard NMEA output and an efficient binary protocol.
