Although Hortis works on GPS-enabled devices, some users may find that the typical accuracy of the map markers is less than desired (accuracy can range up to 4.9 m / 16 ft radius under open sky). This accuracy worsens near buildings, bridges, and trees.
Several users instead have purchased an external high precision GPS/GNSS device with a receiver that communicates with the smartphone or tablet over Bluetooth. Although a slightly more complex setup, this is also more versatile in that you can use different devices and upgrade the data collectors depending on your needs. This configuration is also likely to be useful over a longer period of time.
There are many models to choose from, but we have users reporting positive feedback using:
- Trimble® Geospatial: R2 (Other Trimble R# products might also work well)
- Juniper Systems: Geode
Setting up Geode from Juniper Systems
Geode from Juniper Systems is a sub-meter GNSS solution that can integrate with your smartphone via Bluetooth or USB. When your smartphone is properly configured, you should be able to receive the high precision coordinates to use within Hortis.
To setup Geode, please follow the instructions from Juniper Systems here.
