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.

Functionality The configurable device produces GNSS/IMU data and outputs it via CAN bus
Included CANmod.gps module, u-blox GPS antenna and USB dust cover (mini USB adapter not included)
Firmware Supports free firmware updates via USB for adding features
Configuration Configuration files based on the popular open source JSON schema concept (similar to the CANedge)
Software Free open source editor tool for easy device configuration (offline/online version available)
Safety CE, FCC, IC and RoHS certified (see the Docs for certificates)
Warranty 1-year warranty
Support Free, fast & high quality support
Origin Denmark
Module Professional-grade u-blox NEO-M8U (72-channel) sensor with built-in gyroscope and accelerometer
GNSS Supports (combinations of) GPS (USA), Galileo (Europe), BeiDou (China), GLONASS (Russia)
Geofences Supports 0-4 configurable circular geofences (status sent via CAN bus)
Sensor Fusion (UDR) Enhanced position precision via sensor fusion (UDR) of GNSS and 3D IMU (automotives only)
Acquisition Cold starts: 26 s | Aided starts: 3 s | Reacquisition: 1 s
Sensitivity Tracking/Navigation: 160 dBm | Cold starts: 148 dBm | Hot starts: 157 dBm
Battery Backup The module has a battery backup to enable 'aided starts' (3 s) between power cycles
Accuracy Position: 2.5 m CEP (Circular Error Probable)
  Heading: 1 degree (50% at 30 m/s)
  Velocity: 0.05 m/s (50% at 30 m/s)
CAN Signals The module communicates several GNSS/IMU signals (for a full list, see the Docs or DBC file)
  GNSS position: Longitude and latitude information [1 Hz]
  GNSS time: Precise GNSS based epoch timestamp [1 Hz]
  GNSS status: Fix type (NO/UDR/2D/3D/GNSS+UDR) and satellite count [1 Hz]
  GNSS speed: Travel speed in meters/second [1 Hz]
  GNSS altitude: Altitude information in meters [1 Hz]
  GNSS attitude/orientation: Roll, pitch, heading [1 Hz]
  GNSS odometer: Distance traveled (since power on and total) [1 Hz]
  3D IMU: Gyroscope-based angular rate (X, Y, Z) and accelerometer-based acceleration (X, Y, Z) [100 Hz]
  Geofences: Status of the configured geofences [1 Hz]
Channels 1 x CAN channel
Modes The device can either broadcast the data onto the CAN bus - or provide it on-request
Standard ISO 11898: Compliant with CAN (up to 1 Mbit/s)
Identifiers Compliant with CAN specifications 2.0A (11-Bit ID) and 2.0B (29-Bit ID)
Termination Termination can be toggled via switch below DB9 connector
Retransmission Retransmission of frames that have lost arbitration or been disturbed by errors
Transceiver Protection Protection: +/- 25kV HBM ESD, +/-12kV IEC ESD, +/-14 V bus fault, short circuit
Common mode input voltage: +/-12V
TXD dominant timeout (prevents network blocking in the event of a failure)
Bit Rate Select between standard bit rates (5K to 1M) or use custom bit-timing
Enable/Disable Individually enable/disable each CAN message
Identifier Customization Individually configure CAN IDs for all messages (11-bit or 29-bit)
Push/Poll Mode Individually configure 'trigger' modes for all messages (push or poll)
Frequency Individually configure prescaling of the default message frequencies to lower rates
IMU Correction Optionally compensate the orientation of the module as part of the IMU configuration
Input Supply +5V to +26V DC via the DB9 connector (power via pin 1 or pin 9)
