1Overview
Thank you for purchasing and using UB4B0 GPS/BDS/GLONASS/Galileo
ALL-Constellation Multi-Frequency High Precision OEM Board. The UB4B0 can provide
reliable centimeter-level accuracy and high accuracy heading output at high update
rate .UB4B0 employ the new generation all-constellation multi-core high precision SoC chip,
Nebulas-II (432 channel tracking), based on mature base line chip (XINGYUN)，55nm low
power consumption，built in broadband ADC and anti-interference unit，integrated two
600MHz ARM processor and special High speed floating point processor，provides more
powerful satellite navigation signal process ability. UB4B0 provide millimeter-lever
carrier-phase observation data and centimeter-lever 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）etc. advanced instantaneous RTK and
long-distance RTK.

2Installation
This section contains the list of the product package and the details of product installation.
2.1
Package Inspection
Please check the contents of the package carefully after receiving the package of UB4B0：
UB4B0 board and EVK suite (or evaluation board) (or enclosure)
User manual (CD attached)
Command manual (CD attached)
UPrecise software (CD attached)
5
MMCX antenna cable
Cross serial Port cable
2.2
ESD Protection
A lot of components onUB4B0 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 under anti-static
work bench, a conductive foam pad, and at the same time, wearing an anti-static wrist
strap. If ESD workstation is not available, wear an anti-static wrist strap and attaching 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 put the boards
Please carefully check for obviously loose or damaged components after removing the
package from the boards. Any questions, please contact your local dealer.
Please save package boxes and plastic containers，for storage and
transport.

1. RF part
The receiver gets filtered and enhanced GNSS signal from the antenna via a coaxial
cable. The RF part convert the RF input signals into the IF signal, and convert IF analog
signal into digital signals required for Nebulas die (UC4C0).
2. Nebulas SoC（UC4C0）
Nebulas-II (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. MEMS*
This is an optional function. If selecting GNSS+INS，UB4B0 is integrated on-board
7
MEMS chip, which can maintain excellent application experience even in the most
challenging environments such as urban canyons，and can effectively solve the
interruption of the positioning data caused by the satellite signal covered. It can
provide continuous, high quality and high output rate positioning results. In addition,
UB4B0 also supports odometer Input and external high-precision IMU interface,
providing better integrated navigation and positioning performance.
4. 1PPS
UB4B0 provides1 PPS with adjustable pulse width and polarity and 1 output pulse
width.
5. Event
UB4B0 provides 1 Event Mark Input.
6. I/O
Power input, data communication port, pulse trigger, LED etc.
