Description
The CHC GNSS antennas provide a high-accuracy and cost-effective solution to demanding positioning applications such as geodetic reference stations, marine surveys, machine control, GIS, and mapping when performance and reliability are required. It offers:
- Multi-constellation GNSS tracking
- Advanced phase centre accuracy
- Advanced multipath rejection
The AT312 supports all current and upcoming GNSS signals, including GPS, GLONASS, BeiDou, Galileo, QZSS, IRNSS, SBAS, and L-Band. The AT312 advanced LNA and optimised ground plane technology significantly reduce multipaths’ impact on measurement accuracy. The IP67 industrial design of the AT312 makes it safe to use in harsh conditions within a wide operating temperature range. The AT312 features 40-dB signal gain and a low elevation GNSS signal tracking capability even in challenging surroundings.
