UR4B0 is a new generation, multi-system and multi-frequency high precision CORS receiver supporting triple-frequency BDS navigation satellite system. It is based on Unicore’ multi-system, multi-frequency and high performance GNSS SoC – Nebulas-II™ and features millimeter level carrier phase observation, large memory, multiple communication interfaces and protocols. It is especially suitable for surveying, meteorology, earthquake and deformation monitoring, scientific research and other high precision measuring and positioning fields.
CORS receiver supporting tri-band signal of Beidou system
high precision CORS receiver, UR4B0 also supports BD B1, B2, B3 signals and
Galileo system, besides the existing reference station applications based on
GPS/GLONASS system. This ensures a seamless upgrade process of existing CORS
system services and reduces the upgrade costs for CORS operators.
standard interface protocols for CORS applications
supports multiple standard application interfaces of CORS receiver, such as a
network interface, RS232, 1PPS and an external clock. It meets the demands for
remote control and data transfer of the receivers, time synchronization of station
devices, stable atomic clock and other peripheral interfaces. UR4B0 supports
TCP/IP, HTTP, NTRIP and FTP Protocols, available to transmit the raw
observation data streaming, real-time differential data streams and observation
file of the receiver through network interface.
is based on Unicore’s
Nebulas-II multi-system, multi-core high precision SoC. It supports 432
channels as well as includes a built-in broadband ADC and an anti-interference unit,
while the two 600MHz ARM processors and a special high-speed, floating-point
operation CPU provide more powerful signal processing capabilities
supports web interface, so users can configure the boards web interface through
Internet Explorer to realize status monitoring, such as satellite tracking,
positioning and data storage. In addition, users can also conduct operations
like remote restart and firmware upgrade. Four LED indication lights and one button
are provided on the front panel, enabling operations of power-on and data
recording as well as indicating the status of the power supply, satellite and positioning.
