Description

GPS L1 & L2 Antenna – Filtered – SMA Connector – HXGL01052-SA01

Part of the HXGL series of Dielectrix antennas from Helix Geospace which are extremely resilient, ruggedised designs and built for hand-held and other applications where size and performance are crucial.

The HXGL01052-SA01 dual band antenna delivers high performance that belies it’s small size, due to the patent-protected use of specialised dielectric core material. The antenna is available with an over-moulded protective radome, or as a bare antenna that customers can integrate directly into products.

Helix Geospace HXGL series antennas are ideally suited for PNT (Position, Navigation and Timing) applications in which resilience, position accuracy and compact form factor are essential:

• Precision location and navigation
• Precision Timing for network sync and crypto
• Defence/security/CNI/first responder
• Autonomous vehicles and drones
• Asset tracking and fleet vehicle tracking
• Internet of Things
• Personal safety devices
• Hand-held and wearable location devices
• Industrial/Oil & gas/Mining.

GPS L1/L2 Antenna

The Helix Geospace L1/L2 Antenna is a dielectric loaded decafilar helix, which uses patented Dielectrix antenna technology to provide the highest available efficiency per unit of size/volume.

These antennas have excellent co-to-cross polarisation and therefore provide useful discrimination of multi-path (reflected polarisation-reversed) signals. They are balanced and isolated from platform ground, ensuring high immunity to common-mode noise and very low proximity de-tuning caused by nearby objects.

HXGL01 Series Dielectrix Antennas deliver predictable installed performance that belies the small size, due to operation of the dielectric-core material (patent-protected).

• Intrinsic band-pass filter response, tightly tuned to L1 and L2 frequency bands – provides protection from to out of band interference.
• Focused phase centering that is highly accurate and reproducible – a key requirement for autonomous positioning
• Immune to static discharge and lightening splashes
• Low de-tuning due to objects in the near-field – Ideal for hand-held and vehicle-mounted applications
• Cardioid radiation pattern – optimal reception of signals from low elevation satellites, and when antenna is in a dynamic application (e.g. maritime, airborne and vehicle applications)
• Balanced antenna – resilient to common-mode noise (e.g. vehicle chassis ground fluctuations due to in-car compute and electric drive-train noise)
