Engine module u-blox NEO-M8U UDR GNSS receiver
NL-82052RS, NL-82052USB und NL-82052TLL
manual (62764, 62763, 62745)

1. Introduction
The engine modules are serial, USB and TTL GNSS receiver with an internal active antenna.
The GNSS receiving is realized using the u-blox NEO-M8U module. In this module, high-sensitivity
sensors such as a 3D accelerometer and a 3D gyroscope are also integrated. These sensors enable the
acquisition of dynamic three-dimensional motion data. These include speed, acceleration, direction and
inclination. From this data, the engine modules acquires position data that complements the current GNSS
position data. They allow reliable position determination even when the GNSS signal is interrupted in the
case of four-wheeled vehicles.
In order to be able to fully utilize the UDR functionality, the receiver must be firmly and unchangeably
connected to the chassis of the vehicle. At the first commissioning after reaching the 3D Satfix, an
approximately 20 minute trip with a speed of more than 30 km/h has to be completed. The journey can be
completed in normal road traffic with curves and acceleration periods. During this travel, the above-
mentioned sensors values are calibrated fully automatic. During this time, the receiver supplies the normal
GNSS position data. From the time of the successful sensor calibration, the UDR position data is added to
the GNSS position data in the NMEA 4.1 protocol. The UDR data is determined and delivered with an
updating rate of 20 Hz.
Due to the additional UDR position data, the receiver reliably delivers its position immediately after
switching on even in the car park or garage.
If your vehicle is moved without its own force after calibration (towing, ferrying, etc.), the receiver
automatically discards its calibration data. At the next trip meeting the above criteria it will be automatically
recalibrated.

5. Application environment
The USB Engine module can be installed on Windows 7/8.1/10, CE and Linux operating a GNSS receiver.
But it is not suitable for WINDOWS 98/98SE/Me or MAC OS. No drivers are available for this purpose. The
serial and TTL version can be used without dependencies to the OS. There's only concerning the
restriction of u-center testing tools, it is available only for Windows 7/8.1/10 and CE.
6. Functional test with u-Center 8.xx
6.1. Install the u-Center software on your unit. Select the version suitable for your system.
U-center is a pure test program and cannot be used for navigation or orientation. It must always
be closed after the test. It blocks the COM port and does not allow any access of the navigation
or route software to the COM port. It also serves for updating the Assist GNSS data and
switching to EGNOS.
If the NMEA protocol is displayed in u-Center, but you cannot find a receiver in the application software,
the connection problem is not with the receiver, but with the selected software setting. In this case, the
software manufacturer support center may be able to help you.
As seen below, you can set up your u-center by yourself. Everything important can be connected and
displayed immediately. The green bars at the bottom of the picture show the reception quality at your
position. If no bars are displayed, please change your position. The engine module cannot receive
anything in a closed building. If the blue bars are displayed, the receiver is still acquiring the data and
verifying the receipt data.

7. EGNOS configuration with u-center 8.24
View\Configuration View
The engine module use EGNOS as default. In the configuration menu you can check these options. For
detailed information please use the documentation from u-blox http://www.u-
blox.com/images/downloads/Product_Docs/u-Center_User_Guide_(UBX-13005250).pdf.
Further information to the u-center can be found in the u-blox documentation under http://www.u-
blox.com/products/u_center.html. If you have any questions, please contact u- blox directly.

8. AssistNow configuration with u-center 8.xx
The engine module supports AssistNow!
AssistNow is a standard A-GNSS service, which increases the performance of the GNSS
receiver, by calculating a position almost immediately, even under difficult reception conditions.
A-GNSS improves all GNSS capable applications, especially those that require a continuous
state of readiness, for example applications for fleet management or GNSS capable hand-held
devices, whose users would like to access local services immediately, independently of the
reception conditions.
Without A-GNSS, a GNSS receiver must localize at least 4 satellites in direct line of vision, and
then download their location data. This process takes 30 seconds under optimal reception
conditions, but under less favourable conditions it may take much longer, e.g. in an urban
environment or in a building, where the GNSS reception is weaker. AssistNow sends the data
directly to the GNSS receiver, thus enabling a quick calculation of the position. AssistNow sends
the data directly to the GNSS receiver, thus enabling a quick calculation of the position.
The offline service provides support data, which are valid up to 35 days. The user can thus profit
for longer periods from the increased satellite acquisition performance, and they need an internet
connection only occasionally, in order to update the support data.
The call-up and data transmission functions can be found in the menu bar of the u-center.
Click on the AGNSS function in the menu bar to update AssistNow and to load the engine
module. Please use the following server token in the configuration menu:
8cLxZxp_10Wya9h1eU_gBA
Further information to the u-center can be found in the u-blox documentation under https://www.u-
blox.com/en/product/u-center-windows. If you have any questions, please contact u-blox
directly.

9. Possible sources of error and their elimination
9.1 The white LED doesn’t light up after the first connection to the port. Make
sure that the PC or notebook is turned on, and test the port, possibly with
another device. If this other device works fine, please contact the
support centre.
9.2 The engine module needs up to 20 minutes for its first satfix on another continent.
To get a satfix the view to the sky must be unobstructed. Move the engine
module as far as possible from the wall. A house wall reflects the signal strongly
and contributes to the satfix time delay.
9.3. The engine module came in touch with jet water (water jet from a shower head or strong
rain (when it was mounted on a car roof). Do not connect the receiver with the notebook
etc. under any circumstances, because it will otherwise be completely and irreparably
destroyed. Return the receiver to our support centre, mentioning “water damage”. The
support centre will disassemble the module, dry it and check its functionality.
The Navilock repair centre tries to be as obliging as possible, so please tell us the real reason for
the defect. During the error analysis, we can generally detect if the cause for the defect was an
external cause, water damage, fall, over-voltage or the wrong handling of the unit.
Failures are often the result of little causes. It is not always necessary to exchange the product
immediately, because this will not solve the cause of the failure if it is not a GNSS hardware
problem.
Before visiting your dealer, please contact the Navilock support centre. They will try to help you
quickly and without further ado, so that the circumstances of an exchange, which might in any
case be unnecessary, are avoided.
In this case, please write down a detailed description of the error, add this information to your
end device and the software used in this device, as well as the operation environment (operating
system, service pack version, CUP size and type, storage size, hard disk drive and interface
etc.), and send an e-mail to support@navilock.de.
A support member will look into your problem and work out a solution.
We hope your Navilock product brings you fun and enjoyment!
