Right Wheel Speed Sensor

This function is designed for the right wheel of a vehicle with dual wheel speed
sensors.
12.3.22

1PPS Input

This function is designed to allow external GNSS receivers to synchronise time with
Spatial Dual. It triggers on a transition from low to high.
12.3.23

Wheel Speed Sensor

This function is designed for high resolution vehicle speed sensors and wheel speed
sensors. It expects a normally low input with a high state for the trigger. If the pulse
length is more than 0.1 metres the odometer input function should be used, if it is less
than 0.1 metres the wheel speed sensor function should be used. Please contact
Advanced Navigation support for help integrating with your speed sensor.
12.3.24

Wheel Encoder Phase A

This function is designed for rotary incremental quadrature encoders. It should be
used in combination with Wheel Encoder Phase B.
12.3.25

Wheel Encoder Phase B

This function is designed for rotary incremental quadrature encoders. It should be
used in combination with Wheel Encoder Phase A.
12.3.26

Event 1 Input

This function is designed to allow external events to be recorded inside Spatial Dual's
output. The event is recorded in the filter status, see section 13.9.1.2, and resets after
the next packet is output. The event triggers on a transition from low to high.
12.3.27

Event 2 Input

This function is designed to allow external events to be recorded inside Spatial Dual's
output. The event is recorded in the filter status, see section 13.9.1.2, and resets after
the next packet is output. The event triggers on a transition from low to high.
12.3.28

GNSS Receiver Passthrough

This function allows for pass through connection to the internal GNSS receiver. This is
useful for firmware updates of the internal GNSS receiver.
12.3.29

TSS1 Output

This function outputs the TSS1 format at a user configurable rate up to 50 Hz. The
output rate can be configured using the GPIO output configuration dialogue in Spatial
Manager, see section 11.8.11.
