Overview

The patent-pending VSP6237L antenna employs Tallysman’s unique VeroStar™ technology, providing high gain over the full GNSS spectrum: GPS/QZSS-L1/L2, GLONASS-G1/G2, Galileo-E1, and BeiDou-B1, including the satellite-based augmentation system (SBAS) available in the region of operation [WAAS (North America), EGNOS (Europe), MSAS (Japan), or GAGAN (India)], as well as L-band correction services.

Features

  • Tight phase centre variation (≤ 2.0 mm)
  • Low axial ratios from zenith to horizon
  • Low roll-off from zenith to horizon
  • High G/T at low elevation angles
  • Invariant performance from 3.0 to 16 VDC
  • Low current (50 mA)
  • Low noise figure (1.8 dB)
  • Light, compact, and robust design
  • IP69K, REACH and RoHS compliant

Benefits

  • Consistent performance across all frequency bands
  • Excellent GNSS tracking from low elevations
  • Extreme accuracy and precision
  • Excellent multipath rejection


Details

The light and compact embedded VeroStar™ VSP6237L is designed and crafted for high-accuracy positioning while being robust and reliable:

With an exceptionally low roll-off from zenith to the horizon, the VeroStar™ antenna provides the best-in-class tracking of GNSS and L-band correction signals from low elevation angles. In addition, the optimized axial ratio at all elevation angles results in excellent multipath rejection, thus enabling accurate and precise code and phase tracking of GNSS and L-band correction signals.

A wide-band spherical antenna element enables the VeroStar™ to deliver a ±2 mm phase centre variation (PCV), making it ideal for high-precision applications, such as autonomous vehicle navigation (land, sea, and air), smart survey devices, and maritime positioning.

The VeroStar™ antenna features a robust pre-filter and high-IP3 LNA architecture, minimizing de-sensing from high-level out-of-band signals, including 700 MHz LTE, while still providing a noise figure of only 1.8 dB.

The housed antenna, featuring an integrated rubber bumper to absorb routine impacts, has passed a battery of tests (water pressure, altitude, salt fog, shock, drop, and vibration) to ensure it can survive the rigours of day-to-day field use.
