Description

This high-precision GPS/GLONASS GNSS antenna is engineered for applications demanding exceptional positioning accuracy, leveraging simultaneous signal acquisition from both GPS and GLONASS satellite systems. Its remarkably compact footprint allows for seamless integration into projects where space is a critical constraint, without compromising performance. The inclusion of a 3-meter cable offers significant flexibility for installation, enabling enhanced GPS signal reception even in indoor settings when connected to platforms like Raspberry Pi HATs or Arduino Shields.

Constructed for durability, the antenna features a robust IP67 waterproof and UV-resistant enclosure, ensuring reliable operation in harsh outdoor conditions. A built-in flat magnetic surface provides convenient temporary attachment to metallic surfaces, while permanent mounting can be achieved with double-sided tape. The internal high-gain wide-band patch antenna, coupled with an integral ground plane, delivers consistent and strong signal acquisition. Furthermore, a sophisticated mid-SAW filter configuration actively mitigates the risk of LNA burnout from out-of-band radiated power, safeguarding the preamplifier from interference by nearby co-located antennas. This antenna is manufactured to stringent automotive-grade quality standards, promising long-term reliability.

Key Features
