4.3 Working with CORS/RTK Correction Service

To use the CORS/RTK Correction Service, follow these steps:

1. Purchase a CORS/RTK Correction Service account in your local area.
2. Ensure your PDA device (phone/tablet/data collector) can access the network and supports Bluetooth connection.
3. Place your L1 GNSS receiver in an open view wa angani.
4. Open SingularPad software.
5. Click "Communication" and connect to your L1 receiver's SN via Bluetooth.
6. Click "Rover" and then "Set Data Link" as Phone Internet. Go to "Connect Mode" and fill in your CORS/RTK Correction Service account details.
7. Click "Get" to obtain the Mount-Point list and select the appropriate one. Click Start and Apply.

Kumbuka: Find the appropriate mount point via the website of your local CORS/RTK Correction Service provider. Ensure the baseline is within 50km.

4.4 Working with L1 Rover + Base

For a Rover + Base setup, you will need two L1 GNSS receivers. Designate one as the base and the other as the rover.

1. Connect the L1 base to your PDA. Go to Device > Base.
2. For Base Startup Mode, you can input known point coordinates to set up, or select Single Point mode for automatic setup.
3. Set Datalink as Internal Radio and customize radio channels, frequency, and protocol according to your needs.
4. Save settings and Start Base. The status bar will become Base.
5. Disconnect L1 base and connect to the rover in the software.
6. Go to Device > Rover, set Data Link as Internal Radio.
7. Match and set the same protocol and frequency as the base setting.
8. Click Collection to save settings and click Apply.

5. Maagizo ya Uendeshaji

5.1 RTK Precision and IMU Tilt Compensation

The L1-Laser provides robust RTK positioning. Its integrated IMU allows for tilt compensation up to ±60°, enabling accurate measurements without needing to perfectly level the pole. This significantly increases survey efficiency, especially in challenging terrains or when measuring inaccessible points.

Figure 5.1: Illustration of 60° tilt compensation for pole surveying and visual stakeout.

5.2 Laser Measurement

The integrated laser rangefinder allows for non-contact measurements up to 10 meters. This feature is particularly useful for surveying points that are difficult or hazardous to access, such as power lines, bridge abutments, or points across obstacles. Simply aim the laser at the target point, and the system will combine the laser measurement with RTK positioning for precise coordinates.

5.3 Data Collection and Management

The SC60 Data Collector, running SingularPad software, provides a robust interface for data collection. It features a full physical keyboard and a 5.5" 1080P display for efficient data input and viewing. Data can be stored on the L1-Laser's 8GB internal storage and easily downloaded via its Web UI by connecting to the device's Wi-Fi.

5.4 Viewing RTK Positioning Status

After completing your L1 RTK setup, check the current RTK solution status in the top left corner of the SingularPad software:

• IMEFANIKIWA: L1 is receiving RTK corrections stably and obtaining a Fixed RTK solution with centimeter-level accuracy.
• FLOAT: L1 receives corrections from the base/CORS, but due to obstructions or magnetic field interference, the signal reception is not very stable, and the accuracy is sub-meter level.
• HURU: Single-point satellite positioning without receiving RTK correction data. The accuracy is around meter-level.

Kidokezo: Before surveying, make sure L1 has a clear sky view, free from obstacles like buildings, trees, cars, and more.

7. Utatuzi wa shida

If you encounter issues with your L1-Laser equipment, consider the following common troubleshooting steps:

• Hakuna Nguvu: Ensure batteries are fully charged. Check all cable connections. Try a different charger or USB-C cable.
• No GNSS Signal: Hakikisha kuwa kifaa kina uwazi view of the sky, free from obstructions like tall buildings or dense foliage. Check antenna connection.
• RTK Not Fixing (FLOAT/AUTONOMOUS): Verify base station or CORS connection. Ensure correction data is being received. Check radio/Ntrip settings for correct frequency/mount point. Ensure the baseline distance is within recommended limits.
• Bluetooth/Wi-Fi Connectivity Issues: Restart both the L1 receiver and the data collector. Ensure Bluetooth/Wi-Fi is enabled on both devices. Forget and re-pair Bluetooth connections if necessary.
• Utendaji Mbaya wa Programu: Restart the SingularPad software. If the issue persists, restart the SC60 Data Collector. Ensure the software is updated to the latest version.
• Inaccurate Laser Measurement: Ensure the laser aperture is clean. Verify the target surface is suitable for laser reflection.
