CANmod.gps : GPS-to-CAN with 3D Inertial Sensor and UDR
This standalone GPS-to-CAN module produces GNSS position and 3D inertial data (via a gyroscope & accelerometer) and outputs it via configurable CAN bus frames.
Description
This standalone GPS-to-CAN module produces GNSS position and 3D inertial data (via a gyroscope & accelerometer) and outputs it via configurable CAN bus frames.
The module supports 'Untethered Dead Reckoning' - meaning that even if the GNSS signal is lost entirely, the module can deliver continuous positioning through IMU-based estimates (no external inputs required).
You can integrate the module with any CAN bus, e.g. vehicle
networks or CAN hardware. As an example, you can use it as a plug & play
add-on module for the CANedge.
FEATURES
PRODUCT
Easily add GNSS/IMU data to any CAN bus system
The CANmod.gps makes it easy to add position and 3D inertial data to your CAN bus - e.g. for use by ECUs or CAN hardware.
l Compatible with any high speed CAN bus (2.0A, 2.0B)
l Fully configure CAN IDs, bit rate and message frequency
l Power at 5-26 V DC via standard DB9 adapter cables
l Optionally record the data via any CAN interface/logger/...
l Example: Use as add-on for the CANedge (power via 2nd port)
l DBC file included for easy decoding to human-readable form
l Optionally stream sensor data via USB in real-time
l White label e.g. for inclusion in your production
Example: Add GNSS/IMU data to your CANedge log files
