RTKCAN - CAN RTK Receiver
RTKCAN
RTKCAN can provide centimeter level accuracy and is very easy to use. All you need to do is turn on the Android application. CSV Logging is available as well with other features.
Applications for RTKCAN
- Precision agriculture, self driving tractors. Integration to other systems is easy due to native CAN Bus support up to 1Mbit/s.
- Survey and mapping
- Race cars, accurate driving line. Available now.
- In testing: Race motorcycle applications
RTKCAN system Accuracy

RTK system
Plug & play RTK system for MoTeC M1 ECU's. Or can be easily added to any CAN system with the supplied DBC file. Plug & Play Serial output is available if you want to use it with serial display's and loggers.
System supports 2 types of RTK:
- RTKCAN Post Process - Data is stored to the USB disc and post processed in the pits.
- RTKCAN Real Time - RTK is processed in Real time, saved and sent to CAN in 5cm accuracy
RTCM3 data is required for Post Processing and is saved to the USB disc.
System requires 2 antennas, one for the RTK receiver and one for the timing module. This setup will give a very accurate heading information which can be used to calculate slip angle or Lean angle for motorcycles.
Data below is logged using MoTeC C125 and shows the accuracy of the system. Red = MoTeC L10, Green = L20 SA, Blue = RTKCAN.

Construction
Lightweight but still strong, made to anodized aluminum casing. Weatherproof since potted with lifetime warranty (Antenna excluded).
Other advantage is that the cheap antenna is separate and the receiver itself can be installed into a safe location.
Compatibility
Compatible with any CAN system, we have DBC file available to make install simple and fast.
MoTeC Compatibility
Plug & Play with all MoTeC devices, M1 ECU, displays, loggers etc...
Replacement for RaceGrade GPS devices, now included with STC support and MoTeC GPS Async template.
Optional - GPS Pulse
GPS Pulse is a feature where the GPS will send pulses and can be connected to any digital input. So, now GPS speed can be used by any ECU, even without serial or CAN bus. Device is used in many Haltech applications where GPS speed is sent to ECU using digital input.
Optional Android App
Android app shows RTK Status on the screen. Application can be used as a motorcycle or car display showing lap times, engine status, temperature sensor input etc... It can also deliver RTCM messages from a local RTK base station thru the built in NTRIP client.

Optional - RalliTimer
RalliTimer is a new feature that can be used to time rally stages. Timer measures stage times, both directions automatically. GPSCAN/RTKCAN is powered from the phone so no connections to the car are needed.
Report is available after the test is complete and results can be shared immediately to the paddock via any application installed into the device. Average, min, max speeds are available in the report for both directions.
