USB GPS receiver module Navilock NL-651EUSB — 50 channels, USB interface, sensitivity -160 dBmW, 30×30×7.9 mm

Navilock NL-651EUSB is a compact USB GPS receiver module featuring a 50-channel GNSS engine and a standard USB interface for straightforward connection to PCs and embedded systems. With high sensitivity down to -160 dBmW and a 5 V supply requirement, the module provides reliable satellite signal acquisition and positioning in a very small form factor of 30 × 30 × 7.9 mm. The module is designed as an external positioning unit for integration where a small, externally connected GPS receiver is needed.

Advantages

The module combines a multi-channel GNSS receiver with a plug-and-play USB interface, allowing quick setup without additional power management complexity. High sensitivity improves signal reception in challenging environments such as urban canyons or light canopy, while the compact dimensions make the device easy to install on small housings or development boards. Low power operation from a 5 V USB supply simplifies deployment in desktop and embedded applications.

Suitable for

• Positioning and navigation for laptops, industrial PCs and embedded controllers
• Time synchronization and timestamping in data-logging systems
• Location-aware software development and testing
• Portable or field devices that require external GPS reception

Key specifications

• GNSS channels: 50-channel receiver for simultaneous satellite tracking
• Interface: USB (power and data over USB connection)
• Sensitivity: up to -160 dBmW for weak-signal reception
• Power supply: operates from a 5 V USB source
• Dimensions: 30 × 30 × 7.9 mm compact module size

How to use

Connect the NL-651EUSB to an available USB port on the host device; the module uses the USB interface for both power and data transfer. After physical connection, install any required drivers or allow the host operating system to enumerate the device automatically. Use standard NMEA output or vendor-provided tools to read position, velocity and time data from the receiver. Place the module with a clear view of the sky for best satellite reception; signal quality may degrade indoors or under heavy obstructions.

Recommendations

For optimal performance, mount the module where it has an unobstructed view of the sky, avoid proximity to large metal surfaces or sources of RF interference, and ensure the host system provides stable 5 V USB power. When used in development or integration projects, verify driver compatibility and NMEA message settings to match the target application.
