Overview

The TOXU TX-98-HF2 is an integrated GNSS receiver designed for vehicle navigation, industrial positioning and embedded GNSS integration projects.

Based on the Cynosure III GNSS engine, the receiver supports GPS, BeiDou, Galileo and GLONASS satellite navigation systems on the L1 frequency band.

The TX-98-HF2 provides a specified standalone positioning accuracy of 2.5 m CEP. When valid differential GNSS correction data and suitable operating conditions are available, it supports D-GNSS positioning accuracy of less than 1.0 m CEP.

The receiver combines a GNSS engine, built-in antenna, protective housing and connection cable in one compact unit. This structure reduces the number of separate components required during installation.

NMEA 0183 data is transmitted through a standard UART interface, allowing the receiver to connect to compatible vehicle controllers, embedded computers and industrial navigation equipment.

With a navigation update rate of up to 10 Hz, a 3.3–5.5 V DC input and an operating temperature range of −40°C to +85°C, the TX-98-HF2 is suitable for a variety of navigation and positioning environments.

Key Features

Cynosure III GNSS Engine

The integrated Cynosure III engine provides L1 multi-constellation GNSS positioning for navigation and industrial positioning applications.

Four-Constellation GNSS Support

Supports GPS, BeiDou, Galileo and GLONASS satellite navigation systems for broader satellite availability.

Standalone and D-GNSS Positioning

Provides a specified standalone accuracy of 2.5 m CEP and supports D-GNSS accuracy of less than 1.0 m CEP when valid differential correction data and suitable operating conditions are available.

Built-in GNSS Antenna

The GNSS antenna is integrated into the receiver housing, simplifying installation and reducing the need for a separate external antenna and RF cable.

NMEA 0183 Data Output

Outputs standard NMEA 0183 navigation messages for integration with compatible host controllers and navigation software.

UART Communication Interface

Uses a UART interface for communication with compatible embedded controllers, vehicle systems and industrial equipment.

Up to 10 Hz Navigation Update

Supports a navigation update rate of up to 10 Hz for applications requiring more frequent positioning data.

Fast Startup Performance

Provides a typical cold-start time of less than 30 seconds and a typical hot-start time of less than 2 seconds.

Wide Supply Voltage Range

Supports a 3.3–5.5 V DC power supply for integration with different host systems.

Compact Integrated Housing

The receiver measures approximately 59.7 × 56.7 × 13.6 mm and integrates the GNSS antenna and receiver electronics in one housing.

Wide Operating Temperature Range

Designed to operate from −40°C to +85°C for vehicle and industrial positioning environments.

Applications

Vehicle Navigation

Provides GNSS position data for compatible vehicle navigation units, tracking systems and onboard controllers.

Fleet and Asset Tracking

Can be integrated into compatible telematics and tracking equipment requiring UART GNSS data.

Industrial Positioning

Suitable for industrial controllers and positioning terminals requiring an integrated L1 GNSS receiver.

Embedded Navigation Systems

Supports integration with embedded computers and host controllers through UART and NMEA 0183 communication.

GNSS System Integration

Can be used as an installation-ready positioning component in customized navigation and location-based hardware.

System Integration

The TX-98-HF2 integrates the GNSS antenna and receiver electronics into one compact housing. It receives satellite signals, calculates position data and outputs NMEA 0183 messages through the UART interface.

A typical system connection is:

GNSS Satellites → Built-in GNSS Antenna → Cynosure III Receiver → UART Output → Vehicle Controller or Embedded Host → Navigation Application

The receiver requires a 3.3–5.5 V DC power supply. Before connection, customers should confirm the power input, UART voltage level, baud-rate configuration, output-message requirements and connector definition of the host equipment.

The standard cable and connector configuration should be confirmed when placing an order. TOXU can evaluate cable-length and connector customization according to the customer’s equipment interface.
