The TOPGNSS GNSS board module supports multiple satellite navigation systems such as GPS, GLONASS, Galileo, and BeiDou. It can simultaneously track satellite signals from multiple constellations and quickly and accurately determine its position even in complex environments. Compared with single - constellation modules, the reliability and accuracy of its positioning have been significantly improved.
-
High - precision Positioning: By applying advanced signal processing technologies and algorithms, it can achieve centimeter - level positioning accuracy, meeting the application scenarios with extremely high requirements for positioning accuracy, such as surveying and mapping, autonomous driving, and precision agriculture.
-
High Sensitivity: It has excellent weak - signal acquisition and tracking capabilities. Even in urban canyons with severe signal blockage, indoor environments, or areas covered by thick vegetation, it can effectively receive satellite signals and maintain stable positioning performance.
-
Fast Positioning: The cold - start time is as short as 28 seconds, and the hot - start time only takes 1 second. It can quickly obtain positioning information, meeting the application requirements of fields with high real - time requirements, such as vehicle navigation and UAV flight control.
-
Low - power Design: By adopting optimized power management strategies and low - power chips, it can effectively reduce power consumption while ensuring high performance. It is suitable for battery - powered devices and Internet of Things applications with strict power consumption requirements.
-
Interface: It is equipped with a UART TTL interface, which is convenient for connection and communication with various main control chips and external devices, and is easy to integrate into different systems.
-
Industrial - grade Standards: It meets industrial - grade environmental requirements for temperature, humidity, vibration, etc., has high reliability and stability, and can operate normally under extreme temperature conditions ranging from - 40°C to + 85°C. It is suitable for various harsh industrial environments and outdoor applications.
