GNSS RTK Module

The DB713D board is a compact high-precision board developed based on the Dolphin III high-performance chip independently developed by Changsha Haiger Beidou Information Technology Co., Ltd. (hereinafter referred to as Changsha Haiger). It adopts the original "dolphin neuron" signal receiving algorithm. , supports full constellation and full frequency point GNSS signal reception. Track BDS B1I/B2I/B3I/B1C/B2a/B2b+ GPS L1CA/L1C/L2C/L2P/L5+ GLONASS L1/L2+ Galileo E1/E5a/E5b and other satellite signals. Adopting a small classic size, it can be widely used in professional markets such as intelligent transportation, drones, surveying and mapping, deformation monitoring, and precision agriculture.
