OVERVIEW:
The Tersus David is a cost-efficient, palm-sized GNSS receiver designed for surveying, UAVs, AGVs, and agricultural applications. Working with an external GNSS antenna, the free Tersus Survey App and post-processing software, the David GNSS receiver is a low-cost solution for all survey applications, including real-time RTK positioning and data collection for PPK.
A 4GB in-built memory makes it easy to record data for post processing. The compact size, IP67-rated enclosure, and external Bluetooth module alleviates most of the inconveniences encountered in field work.
