    Tallysman, a manufacturer of high-performance GNSS antennas and related components, has introduced a high-accuracy choke ring antenna: the Tallysman VeraChoke.

    Adapting existing innovations on its patented VeraPhase antenna, Tallysman’s VeraChoke offers a choice in form factor for reference and monitoring applications.

    The VC6100, the first model variant of the VeraChoke antenna, shares a common high-efficiency element design with itsVeraPhase counterpart. With the choke-style form-factor, however, the rings have been optimized for all GNSS signals and are slightly pyramidal in shape to improve reception of low-elevation satellites.



    The VC6100 choke ring antenna offers a tight phase center variation of no more than ±1 mm for every frequency. It is capable of receiving all GNSS signals and achieves a very low axial ratio, the company said.

    According to Tallysman, the VC6100 is competitively priced to help increase antenna density for reference deployments, CORS networks and monitoring applications. The antenna also supports large and small SCIGN radomes.

    Tallysman’s GNSS antennas are on display at Booth Number 12.0D.059 at Intergeo, taking place Oct. 16-18 in Frankfurt, Germany.

  • Expert Opinions: What is the GNSS/PNT industry “Issue of the Year”?

    Q: What is the GNSS/PNT industry “Issue of the Year”?

    Jose Angel Avila Rodriguez, signal and security implementation engineer, European Space Agency

    A: The growth of PNT applications has been impressive and will continue. Assurance of PNT will thus gain an ever-increasing role, in both the security and the civil domains.

    For GNSS, the key PNT contributor, there is in addition another challenge: its piece in the PNT cake will be contested by newcomers, such as telecom networks. Whether we will continue talking about A-GNSS or instead talk about Assisted 5G, with GNSS in that case taking on the role of signal of opportunity — that will depend on today’s decisions about future GNSS upgrades, the modernized versions of Galileo second generation, GPS III, and Beidou/Compass III, that will be flying around 2040.

     

    Gyles Panther, president and CTO, Tallysman Wireless, Inc.

    A: The key issues for PNT going forward, and into the indefinite future, are simply stated: availability and accuracy. Re-deployment of the eLoran infrastructure is a no-brainer. A potentially highly negative step would be the introduction of communication services within the mobile satellite L-band downlink frequency band (1525 MHz to 1559 MHz). Multi-constellational receivers track a much larger number of satellites and better disposed SVs (space vehicles) provide a lower horizontal DOP and hence greater accuracy.

    Finally, GNSS needs to be defended against interference both intentional and accidental. Why on earth would we want to damage something that is providing so much utility to mankind?

  • LNA upgrades enable expanded GNSS reception

    LNA upgrades enable expanded GNSS reception

    Tallysman, a manufacturer of high-performance GNSS antennas, has released a family of high-performing economical wideband low noise amplifiers (LNAs) for choke-ring antennas.

    Tallysman offers four models of the LNA with options of 35-dB and 50-dB gain. The capabilities of the models are shown in the table below. The LNAs are designed for upgrading existing choke-ring antennas with Dorne Margolin/EDO elements to receive new and expanding GNSS signals.

    The LNAs provide consistent gain across the full bandwidth and include filters for suppression of out-of-band interfering signals, such as cellular LTE and Iridium signals, while maintaining a low noise figure, high third-order intercept point, small group delay and low power consumption, the company said.

    The enclosure is designed to fit a wide variety of currently deployed choke-ring antennas.

  • Tallysman introduces new high-gain GNSS antennas

    Tallysman introduces new high-gain GNSS antennas

    Tallysman, a manufacturer of high-performance GNSS antennas and related products, has released two high-gain (50dB) GNSS antennas: the TW3152 and TW3752.

    High-gain GNSS antennas are useful in situations where long cable runs are required, such as in timing systems and GNSS re-radiator systems, the company said.

    The TW3152 provides reception of GPS L1. The TW3752 provides reception of GPS L1, GLONASS G1, BeiDou B1 and Galileo E1 signals. Both antennas employ Tallysman’s Accutenna technology, which provides a high degree of multipath signal rejection through the full bandwidth of the antenna.

    According to Tallysman, the antennas are triple filtered to prevent the saturation of the front-end LNA by strong near frequency and harmonic signals, which are a growing concern throughout the world.

    These antennas are available with a choice of radome shape (flat or conical), color of radome (white or grey), as well as a wide variety of connectors.

  • Tallysman antenna selected by Facebook Open Cellular Platform

    Facebook has selected Tallysman’s TW2643POC GPS/Iridium antenna for the Facebook Open Cellular Platform.

    Facebook’s Open Cellular group is developing a cost-effective, software-defined, wireless-access platform to improve connectivity in remote areas of the world, the company said.

    The TW2643POC employs Tallysman’s Accutenna technology in a magnet mount, passive right-hand circularly polarized antenna for the reception of all of the GNSS constellations (GPS L1/GLONASS G1/ Galileo E1/ BeiDou B1) plus Iridum: 1559 to 1626.5 MHz frequency band.

    According to Tallysman, it is certified and specially designed to maximize the performance of Iridium Voice and Data Modems plus the upper GNSS band (1559–1606 MHz).

    The TW2643POC is housed in an IP67 compliant housing and is REACH and RoHS compliant.
