GNSS Timing Dongles

GNSS Timing Dongles for Precise Time Synchronization

Professional GNSS timing dongles provide accurate UTC time and frequency synchronization using signals from global navigation satellite systems. These compact USB timing receivers are designed for applications where reliable timing, low jitter and precise synchronization are critical, including telecommunications, 5G networks, data centers, industrial systems and scientific equipment.

GNSS Store offers USB GNSS timing receivers from u-blox and Septentrio, including solutions based on NEO-M8T, ZED-F9T, mosaic-T and mosaic-G5 technologies. Choose from USB-A, USB-C and rugged IP67 timing dongles for laboratory, network and industrial installations.

GNSS Timing Receivers with PPS Output

A GNSS timing receiver uses satellite signals to provide an accurate reference to UTC. Many professional timing dongles provide a Pulse Per Second (PPS) or time pulse output, which can be used to synchronize external equipment with a highly accurate GNSS-derived time reference.

PPS timing is widely used in systems where ordinary computer clock synchronization is not sufficient. Depending on the receiver and operating conditions, specialized GNSS timing solutions can provide nanosecond-level timing performance.

GNSS timing dongles provide a convenient way to integrate this capability into existing equipment without designing a complete GNSS receiver board into the system.

USB GNSS Timing Dongles for 5G and Telecom Networks

Precise synchronization is essential for modern telecommunications infrastructure. GNSS timing receivers for 5G network synchronization can provide an accurate external time reference for base stations, network equipment and other telecom infrastructure.

Multi-band timing receivers such as the u-blox ZED-F9T series can use multiple GNSS frequencies to improve timing reliability and signal availability.

Depending on the selected model, GNSS Store timing dongles are available with L1, L1/L2, L1/L5 or all-band GNSS reception for different synchronization requirements.

GNSS Timing for NTP and PTP Servers

GNSS receivers are commonly used as an external timing source for NTP servers and IEEE 1588 PTP Grandmaster clocks.

By combining GNSS-derived UTC time with PPS output, a timing server can provide an accurate synchronization reference to other devices across a network.

This makes GNSS timing dongles suitable for data centers, telecom networks, industrial infrastructure, research laboratories and other environments where multiple systems must maintain a common and accurate time reference.

USB-A, USB-C and IP67 GNSS Timing Receivers

Our timing receiver range includes both USB-A and USB-C GNSS timing dongles, allowing easy integration with computers, servers and embedded hardware.

For outdoor and industrial installations, selected models are available in rugged IP67 enclosures that provide additional protection against dust and moisture.

Many receivers also feature an SMA connection for an external GNSS antenna, allowing the antenna to be installed in a location with a clear view of the sky while the timing receiver remains close to the host equipment.

u-blox and Septentrio GNSS Timing Solutions

GNSS Store offers timing dongles based on professional receiver technologies from u-blox and Septentrio.

u-blox timing solutions such as NEO-M8T and ZED-F9T provide dedicated timing functionality for applications ranging from development and testing to advanced network synchronization.

Septentrio timing receivers, including mosaic-T and mosaic-G5 based solutions, provide advanced multi-frequency and multi-constellation GNSS capabilities for professional timing applications.

The best receiver depends on the required timing accuracy, GNSS bands, interface, environmental protection and interference resistance.

Applications for GNSS Timing Dongles

Professional GNSS timing receivers can be used in a wide range of applications, including 5G and telecommunications networks, NTP time servers, PTP Grandmaster clocks, data centers, financial systems, scientific laboratories, metrology, industrial automation, power grids and frequency reference systems.

They are also useful for GNSS development, time and frequency testing, network synchronization and research applications requiring a stable satellite-derived timing reference.

GNSS Timing Receiver vs Standard GNSS Receiver

A standard GNSS receiver is primarily optimized to calculate position, velocity and navigation data. A GNSS timing receiver is designed specifically to provide an accurate and stable time reference.

Dedicated timing receivers can include configurable time pulse outputs, raw GNSS data, low-jitter timing and additional synchronization features that are not normally required in standard navigation receivers.

For applications where precise UTC synchronization is more important than position, a dedicated GNSS timing dongle is therefore the preferred solution.

How to Choose a GNSS Timing Dongle

When choosing a GNSS timing receiver, consider the required timing accuracy and jitter, supported GNSS frequencies and constellations, PPS or time pulse interface, USB connection, antenna requirements and environmental conditions.

For telecom and 5G synchronization, a multi-band timing receiver can provide additional signal robustness. For outdoor installations, consider an IP67 model, while laboratory and development applications may benefit from a compact USB timing dongle.
