1 Overview
Thanks for purchasing and using UB4B0 GPS/BDS/GLONASS/Galileo All-Constellation
All-Frequency High Precision OEM Board. The board employs the new generation
all-constellation multi-core high precision SoC—NebulasII (432 channel tracking), which is
based on the mature baseband technology, with 55nm low power consumption, in which
built the broadband ADC and anti-interference unit, integrating two 600MHz ARM
processors and a special high-speed floating-point processor, and providing more
powerful satellite navigation signal process ability.
UB4B0 provides millimeter-level carrier-phase observation data and centimeter-level RTK
position output, supports advanced multi-path mitigation and low angle tracking; UB4B0 is
suitable for high precision surveying and mapping application, especially for geodetic
surveying, engineering survey, deformation monitoring, mechanical control,
meteorological monitoring, precision agriculture, continuous operation reference station
(CORS), advanced instantaneous RTK and long-distance RTK, etc.

Hardware Design in Considerations
To
keep UB4B0 functioning
normally, the following signals need to be connected correctly:
The module's VCC
should
be
monotonic when
powered on, the initial level
should
be
lower than 0.4V, and the undershoot and ringing should be guaranteed within 5%
VCC
It is recommended to use a power chip with current output capacity greater than
2A to power the board

3.2 ESD Protection
A lot of components on UB4B0 are susceptible to electrostatic damage, which affects IC
circuits and other components. Please follow the instructions below for ESD protection
before open the plastic package:
Electrostatic discharge (ESD) can damage components. Please use an anti-static
work bench, a conductive foam pad, and at the same time, wearing an anti-static wrist
strap. If ESD workstation is notavailable, wear an anti-static wrist strap and attach it to
metal parts of your industrial PC in order to obtain protection against static electricity.
Please use the edge of the board, avoiding to touch the components on the board
while fetching or putting the boards
Please carefully check for obviously loose or damaged components after removing
the package from the boards. If you have any questions, please contact your local
dealer.
Please save the package boxes and plastic containers for storage and transport.

1. RF Part
The receiver gets filtered and enhanced GNSS signals from the antenna via a coaxial
cable. The RF part converts the RF input signals into the IF signals, and converts IF
analog signals into digital signals required for NebulasII chip (UC4C0).
2. NebulasII SoC (UC4C0)
NebulasII (UC4C0) is Unicore’s new generation high precision GNSS SoC with 55nm low
power design, supports up to 12 digital intermediate frequency or 8 analog intermediate
frequency signals, which can track 12 navigation signals with 432 channels.
3. 1PPS
UB4B0 provides 1 PPS with adjustable pulse width and polarity and 1 output pulse width.
4. Event
1
UB4B0 provides 1 Event Mark Input.
5. I/O
Power input, data communication port, pulse trigger, LED etc.
3.4 Installation Guide
UB4B0 is delivered as a board, users can flexibly assemble according to the scenario and
the market need. Figure below shows the typical installation of UB4B0 with evaluation kit
(EVK), users can also use other enclosures to install receiver, using the same method.

Figure 3-2 UB4B0 Installation
For efficient installation, please prepare the following items before installation:
UB4B0 EVK suite (or evaluation board) (or enclosure)
User manual
Command manual
UPrecise software (CD attached)
Qualified antenna
MMCX antenna cable
PC or Laptop with serial ports (Win7 and above), with UPrecise installed
After the above preparation is made, please follow the steps below to install:
Following the steps below to install the device:
1. Align UB4B0 positioning holes and pins with EVK, and fix UB4B0 on the EVK. EVK
provides power supply and standard communication interface for the board, to

, and so on).
Figure 3-3 Installation Step 1
2. Select a GNSS antenna with appropriate gain, and mount it in an open sky area.
Connect the antenna to J1 MMCX port of UB4B0 via coaxial RF cable.
Figure 3-4 Installation Step 2
NOTE: The RF connector on the board is MMCX, please select the appropriate cable. The
signal gain to the RF connector should be within 25 to 35dB. The Antenna connector
provides 5V DC antenna feed.
3. Connect the PC with EVK through serial ports, or through Ethernet ports.
