The brand new antennas from Tallysman supply positioning, navigation and timing impartial of GPS and GNSS

Tallysman Wireless announced the introduction of two lightweight and compact Iridium active helix antennas This can enable global position, navigation and timing without having to rely on GPS / GNSS.

The HC610 and HC610E Antennas are Developed to receive Iridium GPS / GNSS-independent STL signals (Satellite Time and Location) via an encrypted satellite broadcast signal that is strong, secure and can be received indoors.

Because GNSS signals can be jammed (intentionally or accidentally) and tampered with, STL signals are a reliable alternative for incrementing and authenticating time for applications such as power grids, wireless communications networks and financial systems, as well as location for private and public infrastructures.

The Antennas only work in receive mode and allow the installation of Iridium terminals at a distance of several tens of meters from the antenna. Both antennas are light and compact and have a precisely matched screw element that offers an excellent axial relationship and works without a ground plane. They also have a low-power, low-noise amplifier (LNA) and pre-filter to prevent harmonic interference from high-amplitude signals such as 700 MHz band LTE and other nearby in-band cellular signals.

That housed HC610 (24g) is 33mm wide and 54.2mm high and has a rugged, military grade IP67 plastic housing with a base-mounted SMA connector and two screw holes for surface mounting. The embedded HC610E (10g) is only 27.5mm wide and 38.7mm and can be installed in a custom enclosure. It offers an MCX socket mounted on the base. An embedded spiral mounting ring is available as an option, with which the antenna can be attached to a flat surface.

In addition, Tallysman will support the installation and integration of embedded helical antennas to enable a successful implementation and achieve optimal antenna performance.
