Tallysman Introduces New Line of Surface-Mount Full-band and Triple-band GNSS Antennas

Tallysman® Wireless has announced the addition of four new game-changing surface mount VeroStar™ products to its industry-leading line of antennas. The compact and lightweight surface mount VeroStar™ models offer key features not available on other antennas. The new antennas are VSS6037, VSS6337, VSS6037L and VSS6337L.

The VSS6037 supports the full GNSS spectrum, while the VSS6337 supports the GPS/QZSS-L1/L2/L5, GLONASS-G1/G2/G3, Galileo-E1/E5a/E5b, BeiDou-B1/B2/B2a, and NavIC-L5 signals and frequency bands. The VSS6037L and the VSS6337L also include support for L-band correction services.

The lightweight (340 g) and compact wide-band spherical antenna elements enable VeroStar™ to deliver a ±2 mm phase center variation (PCV), making it ideal for high-precision applications, such as precision agriculture, autonomous vehicle navigation (land, sea, and air), and maritime positioning.

The full and triple-band surface-mount VeroStar™ antennas are designed and crafted for high-accuracy positioning. With an exceptionally low roll-off from zenith to the horizon, VeroStar™ antennas provide the best-in-class tracking of GNSS and L-band correction signals at low elevation angles. Also, the optimized axial ratio at all elevation angles results in excellent multipath rejection, thus enabling accurate and precise code and phase tracking. Additionally, VeroStar™ antennas feature 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.

Key Features of VeroStar Antennas:

  • A unique patent-pending full GNSS bandwidth crossed-dipole antenna element with:
    • o   Excellent radiating pattern with low roll off for exceptional low elevation GNSS and L-Band tracking
    • o   High radiating efficiency for optimized signal-to-noise ratio
    • o   Super stable phase center variation (+/- 2mm)
    • o   Excellent axial ratio for improved multi-path rejection
  • A variety of models are available, including dual, triple, and full GNSS frequency coverage with or without L-band support
  • Ideal design and performance for Real-Time Kinematic (RTK) and Precise Point Positioning (PPP, receiving low elevation L-Band Corrections) applications
  • An innovative low noise amplifier with superior out-of-band filtering
  • Waterproof with IP69K compliance
  • A robust and compact design

These unique features of the VeroStar™ antennas guarantee it can deliver high signal-to-noise ratio (SNR), high accuracy, and high precision in the most challenging environments.
