Unicore Communications, Inc., is showcasing two new products at ION GNSS+, being held September 10-12 in Tampa, Florida.

The UM220-INS is a BeiDou/GPS+MEMS dual-system inertial navigation module for in-dash automotive navigation and high-end navigation. Besides dual-system (BeiDou+GPS) GNSS navigation, the UM220-INS features a built in six-axis MEMS and can output a GNSS+MEMS inertial positioning result, making it suitable for applications requiring high accuracy, high reliability, and high continuity positioning.

The second product is the UB280, a BeiDou/GPS dual-system dual-antenna high-precision heading board for precise RTK position and heading. According to Unicore, UB280 is based on Unicore’s mature BeiDou compatible multi-system GNSS system-on-chip (SoC), features low-power design and dual-antenna input, can offer millimeter-level carrier phase observation value and centimeter-level RTK positioning accuracy, and supports multi-path mitigation. Its advanced technology of instant and long-distance RTK is designed for high-precision positioning, navigation, and heading applications in static and dynamic environments.

Features of the UM220-INS include:

• Built-in six-axis MEMS. UM220-INS has a built-in MEMS with a 3-axis gyroscope and a 3-axis accelerometer. The solution fusing GNSS and inertial MEMS enables car-navigation devices to provide a continuous and stable position under complicated environments such as basement parking and tunnels, regardless of satellite visibility.
• High-Sensitivity Design. With Unicore’s Ultra-Sense high-sensitivity design, UM220-INS can provide excellent acquisition and tracking sensitivity under weak signal conditions, maintaining the position continuity and reliability of the receiver.
• High-Integrated Design. Different from traditional GPS navigation products, built-in MEMS devices support the odometer / speed pulse, the reversing signal input, and more integrated, simplified overall unit manufacturers’ design.
• DGNSS and AGNSS Supprt. UM220-INS has extended support for differential GNSS and assisted GNSS positioning functions, and supports RTCM2.3/3.0.
• Backward Compatibility with UM220. The UM220-III N module is backward-compatible with the UM220 in size and interface, which makes upgrades easy.

Features of the UB280 incude:

• Design standard. This board is totally compatible with mainstream OEM boards in dimensions and electrical standards for the convenience of user’s further development. Apart from this, more hardware interfaces are available.
• Rapid RTK Integer Ambiguity Resolution. With super strong RTK algorithms, it ensures more rapid initializing speed and can make a GNSS-RTK solution on multi-constellation, thus ensuring users take the lead in the interoperability era.
• Web Interface. The UB280 supports an Ethernet interface, so users can configure the board through Ethernet, managing, upgrading, and restarting the device remotely.
• Instant Heading Technology. With an innovative RTK algorithm, Unicore has developed the real-time dynamic heading technology on variable baseline length for a moving base station. High-quality carrier observation and perfect RTK algorithm can provide a 0.2° heading accuracy on a 1-meter baseline.
• Graphical Interface. Based on the graphical Control and Display Tool (CDT), the state, SNR and elevating angle of the satellites of all the constellations could be displayed on the screen, which is convenient for application development.

Unicore Communications is located in Booth 118 in the ION GNSS+ exhibit hall.
