1. Product Overview

The TOXU TX-R025 is a GNSS RTK active antenna engineered for high-precision positioning and satellite communication.

It integrates two core functions—high-accuracy navigation positioning and Iridium satellite communication—making it ideal for in-vehicle use, remote operations, and other demanding scenarios.

Originating from TOXU (Guangdong, China), this antenna comes with a 3m low-loss RG174 cable and an SMA plug for plug-and-play installation. 

With a wide operating temperature range of -40~+85℃ and high-gain signal reception, it delivers reliable performance even in complex environments.

2. Core Performance & Advantages

2.1 Dual-Band Coverage: Positioning + Communication in One

Positioning Band: Supports 1575.42MHz GPS L1 frequency. Combined with GNSS RTK real-time kinematic technology, it achieves sub-1-meter positioning accuracy—meeting the precision requirements of in-vehicle high-accuracy navigation, equipment tracking, 

and industrial operations.Communication Band: Compatible with 1616-1626MHz Iridium satellite frequency. In remote areas without 4G/5G terrestrial signals (e.g., mountains, deserts, grasslands), it still transmits positioning data via satellites to avoid signal loss.

Key Benefit: Eliminates the need for separate "positioning antenna + communication antenna". A single antenna fulfills dual functions, reducing installation space and overall costs.

2.2 High Gain + Optimized Polarization: Stable Signal Even in Weak Areas

Strong Signal Capture: Boasts a typical gain of 3.0 dBic in the Iridium satellite band (1616-1626MHz). It efficiently captures weak signals, solving issues like signal instability or interruptions in urban canyons (high-rise blockages) and remote mountainous regions.

Low-Loss Polarization: Adopts R.H.C.P. (Right-Hand Circular Polarization) design, which precisely matches the polarization direction of satellite signals. This minimizes signal transmission loss and enhances the stability of positioning and communication.

2.3 Easy Installation: Compatible with Multiple Devices

Universal Interface & Long Cable: Equipped with an industry-standard SMA plug, it directly connects to in-vehicle hosts, RTK receivers, IoT devices, and more—no custom adapters required. 

The included 3m RG174 cable fits most in-vehicle wiring scenarios (easily reaching from the roof to the host).

Compact Design & Flexible Mounting: Features a mouse-like compact shape that saves installation space. 

It supports two mounting methods—screw fixation or double-sided tape—allowing flexible installation on vehicle roofs or equipment surfaces without compromising aesthetics.

3. Application Scenarios

3.1 In-Vehicle High-Precision Positioning

Compatible Devices: Commercial vehicles, engineering vehicles (excavators, rollers), ambulances, RVs.

Core Value: Provides sub-1-meter high-accuracy navigation to avoid "tunnel signal loss" and "turning deviation" common with ordinary antennas. It also enables real-time vehicle tracking to improve driving safety and operational efficiency.

3.2 Remote/Outdoor Operations

Compatible Scenarios: Geological exploration, polar expeditions, grassland ranch asset tracking, outdoor environmental monitoring.

Core Value: Transmits positioning data via the Iridium satellite band in areas without terrestrial signals, ensuring traceability of equipment, personnel, or assets and preventing "loss due to signal outage".

3.3 Enterprise Fleet Management

Target Users: Logistics companies, hazardous material transportation fleets, car rental firms.

Core Value: Enables real-time fleet location monitoring. Even on cross-provincial remote routes (e.g., mountain highways, border roads), it accurately tracks vehicle trajectories to optimize scheduling efficiency and reduce transportation delays.
