Multiband GPS/GNSS Antennas Deliver Centimeter-Level Accuracy
Developed to provide simultaneous multiband reception for fast, precision positioning, a family of active, multiband GNSS antennas from Taoglas are optimized for GPS, Galileo, GLONASS, and BeiDou satellite constellations. The Levity Series’ AHP24510 (L1/L2/L-Band) and AHP54510 (L1/L5/L-Band) directional patch antennas enable triangulation across several satellites for faster and more accurate acquisition and lock onto signals.
The L-Band capability of Levity Series antennas leverage high-precision GNSS correction services to typically achieve better than 200-cm positioning accuracy, comparing signals to correct for ionospheric delays and other errors.
Multiband acquisition allows for integral redundancy, which can minimize satellite security blind spots, and reduces energy consumption, as faster acquisition demands less system uptime. Primary applications include wearables, navigation, transportation, robotics, precision agriculture, and autonomous vehicles.
Levity Series active antennas have a 45- × 45- × 10-mm wideband, dual-stacked patch design. A dual-feed, low-noise amplifier provides a 28- to 29 dB gain, and a filter is in the mix, too. The maximum antenna VSWR is 1:1 from 1,207 to 1,603 MHz, and the passive antenna efficiency (excluding the LNA) spans from 39.93% to a peak of 68.51% in the L1 band.
Right-hand circular polarization (RHCP) mitigates multipath interference, and the cables and connectors are fully customizable. Development kits are available for the active antennas.
