GPS receiver module Navilock 61840 USB 50 channels

The Navilock 61840 USB GPS receiver module uses the u‑blox 6 SuperSense® chipset and a built‑in antenna to provide high‑sensitivity satellite reception. It connects via USB 2.0 to a notebook or PC and works with standard routing or navigation software. The compact housing (65 × 45 × 22 mm) and a 1.5 m cable make it suitable for desktop and mobile setups. The unit supports assisted GPS and satellite‑based augmentation systems for improved positioning accuracy.

Advantages

The receiver accepts signals from up to 50 satellites simultaneously and offers high sensitivity (up to –162 dBm) and an update rate of up to 5 Hz. It supports AGPS, WAAS, EGNOS and MSAS, and outputs standard NMEA 0183 sentences (GGA, GSA, GSV, RMC, VTG). USB 2.0 connectivity with auto baud up to 115200 simplifies installation on compatible Windows systems. Additional features include IPX6 protection, a magnetic non‑slip base and an LED indicator for GPS status.

Suitable for

• Navigation and route planning on notebooks and PCs
• Location tracking and positioning tasks requiring up to 50 channels
• Integration into desktop or mobile workstations where a compact external GPS is needed

How to use

Connect the Navilock 61840 to a USB port on your notebook or PC. Install any required drivers or allow the operating system to load compatible drivers (supported on common Windows versions). Launch your routing or navigation application and select the USB GPS as the data source. Place the receiver so the built‑in antenna has a clear view of the sky for best satellite reception; the magnetic non‑slip base can be used to secure the unit to a metal surface.

Usage recommendations

For fastest satellite acquisition, enable AGPS when available, position the receiver with an unobstructed sky view, and ensure your navigation software is configured to read NMEA 0183 sentences from the USB port. Avoid prolonged exposure to water despite IPX6 protection; mount the unit in a sheltered location when possible.
