Technical Features
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.
