- Connect to USB Port: Plug the USB-A connector of the receiver into an available USB port on your computer or compatible Android device.
- Mounting: Utilize the integrated magnetic holder to securely attach the receiver to a metallic surface with a clear view of the sky for optimal signal reception. The 2-meter cable provides flexibility in placement.
4.2. Driver Installation
For Windows, Mac, and Linux operating systems, drivers are required for the device to be recognized. Please visit the official LOCOSYS website or refer to the included software CD (if applicable) to download and install the latest drivers for your specific operating system. For Android devices, a dedicated application is available.
5. Operating Instructions
5.1. GNSS Receiver Software Interface (Windows/Linux)
Upon successful driver installation and connection, you can use compatible GNSS software (e.g., LOCOSYS GNSS Freeware, OpenCPN) to visualize and utilize the data from your receiver. The software typically displays satellite signal strength, GNSS data (latitude, longitude, altitude, fix mode), NMEA sentences, and a skyplot of visible satellites.

5.2. Map View Functionality
Many GNSS software applications integrate map views, allowing you to see your current position overlaid on a map. This feature is particularly useful for navigation and tracking. You can often adjust the map scale and view coordinates directly on the map.

5.3. Adjusting Refresh Rate
The LC23030-V2 supports an adjustable update rate from 1Hz (default) up to 10Hz. This setting can be changed via the software's command table or configuration menu. A higher refresh rate provides more frequent position updates, which is beneficial for fast-moving applications.

5.4. Android Application Usage
For Android devices, the LOCOSYS GPS Mouse application allows you to connect to the receiver and view real-time GNSS data. The app typically displays UTC time, speed, course, latitude, longitude, altitude, fix mode, and raw NMEA sentences. It may also include options for logging data or integrating with Google Maps.
