Survey123

Survey123 is a popular app used extensively for GIS applications, offering robust capabilities for data collection and analysis. As an ESRI product, it boasts seamless integration with other ESRI tools and services, providing a comprehensive solution for geographic information system needs. The integration with RoboDot can significantly enhance the accuracy of referencing features and points, ensuring precise and reliable data for critical decision-making processes. This synergy between Survey123 and RoboDot enables users to leverage advanced geospatial technology for a wide range of professional applications.

Survey 123 GNSS setup

Setup

Survey123 for iOS enhances geospatial data accuracy by allowing users to replace the device's internal GPS with a more precise external source via TCP connections. This feature enables connection to systems like RoboDot, ensuring highly accurate location data, which is crucial for precision in professional applications.

The Survey123 device must be on the same networka s the RoboDot for this connection to work.

1. Enable RoboDot TCP in the Web UI settings page

2. In Survey123, configure the provider provider:

   • Select "Network Connection"

   • Use RoboDot IP displayed on the screen

   • Use Port 1000

3. For VRS corrections to RoboDot

   1. Set up the hotspot on RoboDot and connect to it

   2. Seet up the VRS on the RoboDot and connect to it

In this configuration, Survey123 will attempt to establish a connection with RoboDot Touch over TCP to facilitate advanced geospatial operations. When RoboDot has internet access, it can connect to a Virtual Reference Station (VRS) to enable Real-Time Kinematic (RTK) Fixed modes for superior accuracy. As Survey123 does not include an NTRIP client, users must utilize the RoboDot NTRIP client instead. To achieve optimal positioning accuracy, ensure RoboDot is connected to the internet and properly configure a VRS. This setup enhances data precision, supporting critical decision-making tasks with reliable geospatial information.
