Beidou-3 is the world's first satellite navigation system to provide three frequency signal services. The use of dual frequency signals in satellite navigation systems can weaken the impact of ionospheric delay, while using triple frequency signals can construct more complex models to eliminate high-order errors in ionospheric delay and improve the efficiency of carrier phase ambiguity resolution. In theory, this can improve carrier convergence speed. Therefore, the subsequent GPS will also adopt a three frequency signal system.

The Beidou short message communication service is a unique and important feature. It enables BeiDou users to send and receive short message information through BeiDou satellites even in areas without ground communication network coverage

The single BeiDou module refers to a module for positioning based on China's independently developed BeiDou satellite navigation system. The single BeiDou module only receives BeiDou navigation satellite signals (including BeiDou-2 and BeiDou-3), and does not receive GPS, GLONASS, GALILEO and other satellite signals. RTK high-precision positioning is widely used.

The Beidou Navigation System is a global satellite navigation system independently constructed and operated by China. It consists of three parts: space segment, ground segment, and user segment, and can provide high-precision and reliable positioning, navigation, and timing services for various users worldwide. The Beidou system has a unique short message communication function and plays an important role in many fields such as transportation, agriculture, surveying and mapping, and disaster relief, greatly promoting economic and social development and national defense construction.

SKG092DB is a low-cost and cost-effective single Beidou positioning module that supports receiving satellite signals such as BDSB1I and B1C. This module has a small size, high integration, and is easy to apply, making it very suitable for GNSS scale applications with high cost requirements.
