Introduction
The UWB/RTK precise positioning module SIO02 is a member of the KYT Sensor family by Ci4Rail and can work as a standalone device as well as in combination with ModuCop MEC0x.
For highly precise positioning in public transport and rail car depots, stations, tunnels etc. or even indoor, a single sensor source is not sufficient. To provide precise localization, SIO02 combines the technologies UWB (ultra wide band), GNSS/RTK (Real-Time-Kinematik) and additional speed pulse input signal. Whereas UWB works indoors using a cost sensitive satlet infrastructure, the GNSS/RTK technology provides high precision positioning information without additional infrastructure outdoors. The speed pulse input signal supports identification of distance traveled and movement direction. Specific movement models within an IMU (Inertial Measurement Unit) allow smooth seamless real-time positioning.
The positioning information is transferred to the landside using WLAN interface. SIO02 requires only one cable connection for power input, ignition function and tacho input. The SIO02 product describes the vehicle component and does not cover stationary equipment like UWB satlets.

Mechanical Outline
The Tracelet has the following dimensions
| Dimension | Value |
|---|---|
| Length | 110 mm |
| Depth | 98 mm |
| Height | 48 mm |
Mounting & Installation
The tracelet has to be mounted with clear view to GNSS satellites as well as UWB satlet infrastructure. We recommend mounting on roof of vehicle.
Mounting depends on the given conditions per vehicle. Depending on the mounting conditions, specific mounting brackets might be available. Contact Ci4Rail for specific designs of mounting brackets
In some cases, a snow cover might be useful.
The tracelets have to be mounted in specific orientation to give the best results in positioning. Mounting is done by M5 mounting bolts, lock washers and nuts as shown in the following picture:
Installation Requirements
Due to integrated inertial measurement unit (IMU), the mounting orientation is essential. The Tracelet has to be mounted with an angle of 0° to ground The Tracelet has to be oriented with the M12 connector towards vehicle back (Cab B).
