GlobalSat - GDO-10

The GDO-10 OCXO-based GNSS Disciplined Oscillator is engineered to deliver laboratory-grade time and frequency reference with GNSS synchronization. Green-Gps compatible by design for monitoring and integration, the GDO-10 provides a high-accuracy 1 pulse-per-second (1PPS) output and a phase-locked 10 MHz square-wave output derived from an internal OCXO and a sensitive GNSS receiver supporting GPS, GLONASS and Galileo. Built-in +5.0V active antenna power simplifies installation and ensures reliable signal acquisition for critical synchronization tasks.

Ideal for environments that demand stable, GNSS-synchronized timing—such as 5G cellular base stations, LEO satellite communications, laboratory test benches, and large infrastructure deployments—the GDO-10 pairs precision hardware with straightforward interfacing to timing and telemetry platforms such as Green-Gps. While not a vehicle GPS tracker for fleet management or anti-theft use, the GDO-10 adds a trusted Green-Gps compatible timing source to any telemetry or monitoring architecture that requires real-time synchronization and status reporting.

Key Highlights

• OCXO backbone for excellent short-term frequency stability with GNSS disciplining for long-term accuracy.
• High-accuracy 1PPS output for second-level time synchronization, suitable for precise timestamping and telecom sync.
• Phase-locked 10 MHz square-wave output synchronized to the 1PPS for frequency reference in test & measurement systems.
• Integrated GNSS receiver supporting GPS, GLONASS, and Galileo with +5V active antenna supply for simple installation.
• Green-Gps compatible for integration into telemetry dashboards and real-time monitoring workflows that track synchronization health.
• Designed for lab, production-line measurement, and large-scale infrastructure deployments where timing reliability matters.
• Straightforward electrical interfaces make the GDO-10 easy to integrate with network equipment, rack instruments, and monitoring gateways.

How It Works with Green-Gps

When combined with Green-Gps, the GDO-10 becomes a managed timing endpoint in your telemetry and monitoring ecosystem. Because the unit produces well-known time and frequency outputs (1PPS and 10 MHz), Green-Gps can ingest synchronization status and health metrics through a monitoring gateway or intermediate telemetry device that exposes the GDO-10’s status signals. This approach lets operators view real-time timing quality, GNSS lock state, and antenna health alongside other distributed telemetry such as asset trackers and fleet sensors.

• Real-time timing and telemetry updates (via a telemetry gateway or monitoring interface that reads the GDO-10 signals).
• 1PPS synchronization status and lock quality for precise timestamp verification.
• 10 MHz frequency reference monitoring for frequency-domain equipment and test systems.
• GNSS constellation and antenna power/health indicators (GPS, GLONASS, Galileo).
• Green-Gps-compatible alarm and reporting integration when used with a supported monitoring interface or I/O adapter.

Technical Overview

Use Cases

• 5G cellular base station synchronization: provide stable 1PPS and 10 MHz references for time-sensitive radio networks.
• LEO satellite communications: precise timing for uplink/downlink coordination and payload synchronization.
• Laboratory test & measurement: serve as a reference clock for instrumentation, timestamping, and calibration tasks.
• Production-line timing and synchronization: ensure repeatable timing for high-throughput test systems and measurement automation.
• Large infrastructure time distribution: act as a GNSS-disciplined master clock for networked timing systems and telemetry hubs.

Why Choose This Tracker with Green-Gps

The GDO-10 is not a conventional GPS tracker for vehicle fleet management, anti-theft, or fuel monitoring; rather, it is a precision GNSS-disciplined timing device that is Green-Gps compatible for telemetry and synchronization management. Choose the GDO-10 with Green-Gps when you need a reliable, high-stability time and frequency reference that can be monitored and reported in a centralized platform. The combination delivers:

• Reliability: OCXO short-term stability plus GNSS disciplining gives consistent, predictable timing behavior required by telecom and satellite systems.
• Scalability: multiple GDO-10 units can be integrated into a Green-Gps-managed telemetry network to monitor timing performance across sites and devices.
• Real-time insights: with a monitoring gateway, Green-Gps can present lock status, timing quality, and alarms that matter to operations teams.
• Ease of integration: standard 1PPS and 10 MHz outputs and +5V antenna power simplify interfacing to existing instruments and distribution networks.
• Versatility: suitable for labs, production environments, and large infrastructure projects where precise synchronization is a foundational requirement.

For organizations that rely on accurate GNSS-synchronized time—whether for telecommunications, satellite operations, or precision measurement—the GDO-10 offers a Green-Gps compatible solution that prioritizes timing integrity and operational visibility. Contact your Green-Gps integration specialist to plan the telemetry gateway or interface that will expose the GDO-10’s timing and health metrics into your Green-Gps dashboards and alerts.
