The antenna supports all major global navigation satellite systems: GPS (L1 and L2 bands), GLONASS (G1 and G2), COMPASS/BeiDou (B1, B2, B3), and Galileo (E1, L1, E2, E5b, E6). This multi-frequency, multi-constellation support ensures high availability and accuracy worldwide.
For modern surveying, real-time kinematic (RTK) correction data is typically delivered via cellular networks (NTRIP). The integrated LTE MIMO antenna provides a stable, high-speed data link for receiving these corrections while simultaneously transmitting collected field data, eliminating the need for a separate cellular modem or antenna.
Yes. The standard configuration uses Fakra connectors, but other connector types can be accommodated. Cable lengths for both the GNSS (RG316) and LTE (dual RG178) cables can also be customized to fit your specific installation requirements. Please specify your needs when requesting a quote.
The phase center is the electrical reference point of the antenna. A low, stable phase center error (±2mm) means this point remains consistent regardless of the satellite's direction. This is critical for high-precision (<1cm) surveying and mapping, as it minimizes positioning errors introduced by the antenna itself.
The integrated Low Noise Amplifier (LNA) operates on a wide DC voltage range of 3 to 12 volts, with a typical current consumption of ≤45 mA. This makes it compatible with most survey equipment, vehicle power systems, and battery-powered devices.
The specified frequency range is 698-960 MHz and 1710-2690 MHz, which covers mainstream 4G LTE bands globally. For specific 5G NR band support, please inquire as custom design options may be available depending on your requirements.
Sample units can typically be provided for evaluation. Standard production lead time varies based on order quantity and customization level. Please contact our sales team for the most accurate lead time information for your specific project.
The antenna is designed for professional outdoor use. For detailed environmental specifications such as ingress protection (IP) rating, operating temperature range, and resistance to vibration, please confirm with our sales team as these may be defined based on your customization choices.
