Tallysman Wireless is offering two new VeroStar marine antennas for its GNSS line of products. The VSP6037L-MAR supports the entire GNSS spectrum and the VSP6337L-MAR supports GPS / QZSS-L1 / L2 / L5, GLONASS-G1 / G2 / G3, Galileo-E1 / E5a / E5b, BeiDou-B1 / B2 / B2a and NavIC L5 signals. Both antennas support L-band correction signals.

Ocean-going vessels often host both Iridium (1616–1626.5 MHz) and Inmarsat (uplink: 1626.5–1660.5 MHz) satellite communication antennas that transmit and receive signals. The VeroStar ship antennas VSP6037L-MAR and VSP6337L-MAR strongly attenuate interference from both signal sources and offer an attenuation of 75 dB to 85 dB via Iridium and 85 dB to 95 dB via Inmarsat uplink, which means clean GNSS signal reception and precise positioning enables.

Each VeroStar antenna has a robust pre-filter and high-IP3 LNA architecture that minimizes de-sensing of high-level out-of-band signals, including 700 MHz LTE, while still having a noise figure of only Delivers 1.8 dB.

VeroStar antennas provide the industry’s best tracking of the full GNSS spectrum and low elevation L-band correction signals. The spherical broadband antenna element enables VeroStar antennas to provide phase center variation (PCV) of ± 2mm, making them suitable for high-precision marine, positioning and engine control applications.

The VeroStar marine antennas are housed in a rugged and compact housing that supports 1-inch pipe thread or 5/8 inch 11 TPI mounting and offers a TNC antenna connector. The antennas have also received rigorous marine certifications IEC 60945 and IEC 61108, making them suitable for demanding marine environments.
