6. Setup and Operating Instructions

This section outlines the general steps to set up and operate your Sfaira ONE Plus for surveying tasks. For detailed instructions, refer to the SingularPad software manual.

6.1. Work Mode: RTK Rover + CORS Account

The Sfaira ONE Plus typically operates as an RTK Rover, receiving corrections from a CORS (Continuously Operating Reference Station) account. A CORS account is not included with the product and must be purchased from your local CORS provider.

6.2. Quick Start Guide

Follow these steps to begin surveying with your Sfaira ONE Plus:

1. Step 1: Device Connection via Bluetooth

   Connect the Sfaira ONE Plus receiver to your Android phone, tablet, or data collector via Bluetooth. Ensure Bluetooth is enabled on both devices and pair them through the SingularPad software.

3. Step 3: Log in to RTK Correction Service Account (CORS Account)

   Access the Rover settings in SingularPad. Configure the data link to use your phone's internet connection or connect to your RTK base station in GSM mode. Enter your CORS account details (server IP, port, username, password) to receive RTK corrections. Select the appropriate MountPoint from your account.

4. Step 4: Initialize Tilt IMU Function & Start Surveying

   Once connected and receiving corrections, initialize the tilt IMU function by gently shaking the survey pole for approximately 5 seconds. This calibrates the IMU for accurate tilt compensation. Verify that the RTK status changes to "FIXED" in the software, indicating a stable and accurate solution. You can also view the number of satellites being tracked. With a FIXED solution, you can begin your surveying tasks with centimeter-level accuracy.
