Engineered for precise, resilient GNSS reception

Full-Band GNSS

Tracks GPS/QZSS, GLONASS, Galileo, BeiDou, NavIC, SBAS, and L-Band correction services.

Stable Phase Center

Centimeter phase-center repeatability supports precision positioning and heading stability.

Multipath Rejection

Improved filtering suppresses reflected signals and helps preserve clean GNSS measurements.

Low-Elevation Gain

Strong RHCP reception maintains signal quality when satellites are closer to the horizon.

Rugged IP67 Design

Sealed construction, wide operating temperature range, and 1.5m drop resistance suit field use.

Low-SWaP Integration

Compact size, low weight, and 25mA typical current minimize platform integration impact.
