Bynav Technology has developed the X2, an automotive-grade GNSS/INS positioning unit designed as a mass-production solution for manufacturers and system integrators of autonomous driving platforms.
Measuring just 79 x 63 mm, the X2 is a credit card-sized rugged module equipped with an Automotive Ethernet interface and supporting the GPTP precision time protocol, as well as L-band signal reception and PPP and PPP-RTK. It allows seamless switching to RTK/PPP modes in areas with poor N-RTK service coverage, providing high-precision positioning results through satellite-based enhanced signals even in environments with no mobile signals, with no base station required.
Based on deeply coupled GNSS/INS technology, the X2 can output absolute centimeter-level positioning at rates of greater than 200Hz. It is ideal for operation in urban canyons, tunnels, foliage canopies, severe weather such as heavy fog, rain, snow, and dust, as well as complex environments such as traffic jams, neon lights, worn lane lines and open road sections with no feature points. It can also be integrated with odometers to further improve the accuracy and stability of the GNSS/INS data.
The X2 supports all GNSS constellations, and provides heading accuracy of 0.08 degrees with a 2 metre baseline, and a roll and pitch accuracy of 0.2 degrees.
