The ultimate GPS+GLONASS+SBAS Dual-Frequency OEM Board

With the new MB 500 multi-constellation board, Ashtech brings to the OEM market a unique blend of technologies which increases RTK availability and data integrity. Embedded BLADEâ„¢ technology ensures powerful performance and a patented way to use multiple GNSS constellations for high-accuracy positioning, and surveying solutions:

• Fast initialization and accuracy at long-range


• Patented multi-constellation signal processing


• Advanced multi-path mitigation and robust signal tracking


• RTK solution maintained if data link is briefly dropped


• Interoperability with any vendor's reference station transmitting GPS+GLONASS L1/L2

Unique and Powerful BLADE Technology

A growing number of available satellites are providing significantly improved GNSS receiver performance in difficult satellite tracking conditions. However, GLONASS signal quality is not always stable. GNSS receivers must be able to overcome this instability to ensure high-quality RTK results. The MB 500 board with BLADE has the ability to provide the best possible measurements from three constellations – one of the key differentiators offered by the BLADE technology. The board itself makes all the checks and preparations needed to mitigate any negative effects of GLONASS signal instabilities. The result is more reliable measurement processing and usage than with competing board offerings.
Additionally, the MB 500 board can work with any other manufacturer's base or reference stations by automatically measuring and removing the biases that are inherent with the Frequency Dependent Multiple Access (FDMA) technique used in GLONASS. The MB 500 gets the full benefit of any available GLONASS corrections.


Seamless Integration and Flexibility

The MB 500 features low power consumption in a compact board design, and a variety of output messages and data formats for extensive OEM solution interoperability.
The MB 500 multi-constellation board works as either a base or a rover and is available from L1 GPS+GLONASS up to L1/L2 GPS+GLONASS+SBAS to adapt various customer needs. The MB 500 supports standard and advanced RTK operations such as:

• RTK base up to 20Hz update rate


• Time-tagged RTK and fast RTK


• Standard RTK against a single static base


• Advanced RTK against a moving base for relative positioning


• Advanced RTK solutions using SBAS and GLONASS satellites


• Network RTK using third party network corrections: VRS, FKP, MAC


• Heading and pitch or roll determination with baseline auto-calibration between two receivers
