Autonomous Navigation GNSS MEMS

Advanced Navigation’s Next-Gen Satellite Compass

Advanced Navigation, a leader in AI-based navigation solu- tions, has released the second generation of its satellite compass.

GNSS Compass is a plug and play solution that provides accu- rate position, heading and time in a self-contained unit. The new system provides signi? cantly higher heading performance, com- bined with a reduction in price to under $2,000, opening up the advanced technology to cost sensitive applications previously dependent on magnetic heading.

The new system signi? cantly improves the availability and accuracy of heading under dif? cult conditions, such as under bridges, when there is limited visibility of the sky and in the pres- ence of RF interference. This is achieved through a new multi- frequency GNSS receiver, cutting edge antenna design and algo- rithm improvements.

The updated GNSS Compass supports L1/L2 RTK position-

GLONASS, Galileo and BeiDou. Two interface variants are for marine applications requiring accurate heading and position- available to cater to all applications. The serial variant supports ing in the most demanding conditions. The second generation plug and play operation with existing NMEA 0183 and NMEA delivers the same ultra high reliability, with higher performance, 2000 applications. The Power over Ethernet variant allows sim- at a more affordable price point. GNSS Compass v2 is shipping pli? ed power and network cabling for all new applications. Used now.
