GPS receiver module Navilock NL-650ERS — Serial interface, 50 channels, -160 dBmW sensitivity, 5 V, 30×30×7.9 mm

Navilock NL-650ERS is a compact GPS receiver module designed to provide GNSS position data via a serial interface. The module supports up to 50 tracking channels and achieves a sensitivity of −160 dBmW, making it suitable for use in constrained or low-signal environments. The device operates from a 5 V supply and has a small form factor of 30 × 30 × 7.9 mm, enabling integration into embedded navigation systems, telemetry units, trackers and custom electronics that require reliable satellite positioning and timing information.

Advantages

The NL-650ERS combines high sensitivity and multi-channel tracking in a compact package, offering stable satellite acquisition and continuous tracking even in challenging reception conditions. Its serial interface simplifies integration with microcontrollers and industrial controllers, while the low-profile dimensions allow installation in space-limited applications. The module’s electrical characteristics are compatible with standard 5 V logic environments, reducing the need for additional level shifting or power conversion when used with common embedded platforms.

Suitable for

• Embedded navigation systems in vehicles and drones
• Asset tracking and telemetry devices
• Timing and synchronization for industrial controllers
• Custom electronics and prototyping with microcontrollers

Key specifications

• Interface: Serial communication compatible with UART-based systems
• Supply voltage: 5 V operating voltage
• Dimensions: 30 × 30 × 7.9 mm compact module size
• Typical applications: position fixing, navigation data output, timing

How to use

Connect the NL-650ERS to a host controller using the serial interface lines for data and configuration, and provide a stable 5 V supply. Place the module with a clear view of the sky or a suitable antenna connection to ensure optimal satellite reception. Use standard NMEA or manufacturer-specific sentences over the serial link to read position, velocity and time data. Configure update rates and output messages through the module’s command set as needed for the application. Observe recommended decoupling and grounding practices in the host design to minimize electrical noise and ensure reliable communications.

Recommendations

For best performance, mount the module where it has an unobstructed view of the sky and away from large metallic objects or RF noise sources. Use a suitable external antenna if the installation environment limits direct sky visibility. Verify serial voltage levels and grounding before powering the module to prevent interface damage. When integrating into industrial systems, allow time for cold start satellite acquisition and consider assisted-GNSS or periodic warm starts to reduce time-to-first-fix where available.
