About
Zenith is a high-performance ceramic patch antenna designed for Global Navigation Satellite System (GNSS) reception in nanosatellite missions. It offers precise positioning capabilities and a compact design, making it suitable for integration into various satellite configurations. The antenna can be seamlessly integrated into a solar or structural panel, or it can be delivered as a standalone unit to provide flexible system design options. It is ITAR free, simplifying its export and use. The product includes the antenna module, an Interface Control Document, one hour of engineering support, and shipping & packaging. Spacemanic offers customization options due to its in-house developed hardware and software. The antenna supports GPS (L1), Galileo (E1), BeiDou (B1), and GLONASS (G1) bands, operating within a frequency range of 1556 – 1618 MHz (VSWR <2). It is available in both active and passive version options, features RHCP polarization, and has a 50 Ohms impedance with an MMCX interface. It has flight heritage.
