u-blox EVK-X20D GNSS Evaluation Kit

Introduction

The u-blox EVK-X20D is a GNSS evaluation kit designed for assessing the capabilities of the ZED-X20D dual-antenna GNSS heading module. It gives developers a practical platform for testing high-accuracy positioning, navigation, timing, and heading functionality before integrating the module into a finished design.

Part Description

The EVK-X20D supports evaluation of dual-antenna GNSS operation, enabling both precise position determination and reliable heading measurements. Unlike systems that derive heading only from movement, a dual-antenna configuration can determine orientation while stationary, making it well suited to machinery, vehicles, and platforms that need dependable directional awareness.

The evaluation kit supports high-precision GNSS technologies including RTK, PPP, and PPP-RTK. These correction-enabled positioning methods can improve location accuracy beyond standard standalone GNSS performance when suitable correction services or reference data are available.

Multiple interfaces are provided to simplify connection to host computers, embedded controllers, test equipment, and application hardware. The kit is intended for engineering evaluation, prototyping, performance characterization, and GNSS integration development.

Applications

Potential applications for the EVK-X20D include:

• Dual-antenna GNSS heading evaluation
• High-precision RTK positioning systems
• PPP and PPP-RTK navigation testing
• Autonomous vehicle navigation prototypes
• Precision agriculture guidance systems
• UAV navigation and orientation systems
• Robotic equipment localization
• Surveying and mapping equipment
• Marine navigation and heading systems
• Industrial vehicle tracking
• Machine control platforms
