3 Getting started

3.1 Software installation

The latest version of u-center (currently version 8.24) is needed for the examples and instructions described in
this document. Internet access is also required during the software installation to ensure that the most up-to-
date components are installed on your system. After installation, the u-center application can be found in the
"u-blox" folder in the Start->Program menu.

3.2 Hardware installation

To test and evaluate the benefits of u-blox's Real Time Kinematic (RTK) technology, two C94-M8P application
boards – the "Base" and the "Rover" – need to be set up as described below.

Connect the UHF antenna to the SMA connector marked with "UHF"

Connect the GNSS antenna to the SMA connector marked with "GNSS"

Connect the micro USB cable to the micro USB port on the board (for power and configuration)

Depending on the evaluation purposes, the test connectors may be used differently

GNSS antenna considerations

In order to optimize the benefit of u-blox's Real Time Kinematic (RTK) technology and achieve high accuracy
performance, the placements of the antennas are extremely important. The recommendations for the GNSS
antenna used with the system are:
The antenna needs to be placed in an open sky environment with unobstrucked visibility to the sky.
Care should be taken to minimize multipath. This can be achieved by using a ground plane, which is
supplied with the application board package for the GNSS antenna, and placing it above nearby buildings or
other obstructions.

If the installation does not provide a natural ground plane, such as a car roof, using a ground plane is
strongly recommended. The ground plane should have a minimum diameter of 10 cm. If better
performance is required due to multipath, then a larger ground plane will improve the performance.
Moving to a lower multipath environment might be required.

For more information, refer to Achieving Centimeter Level Performance with Low Cost Antennas [6].
Correct operation requires a static Base Station.
UBX-15031066 - R06
The two boards are identical. Select one of the boards to
act as a "Base" and one as a "Rover".
