Introduction
The Gravity GNSS Positioning & Timing Module integrates satellite positioning functionality and a real-time clock (RTC). The module automatically obtains satellite time based on a preset calibration period and accurately calibrates the onboard RTC chip. This calibration effectively eliminates time errors caused by the RTC chip during extended operation or accidental situations.
The system automatically cuts off power to the GNSS chip after calibration, significantly reducing overall system power consumption compared to GNSS-only solutions. Additionally, the user has the option to use the module as a positioning module by setting GNSS active all the time， providing accurate longitude, latitude, time, altitude, and other data.
The module offers two data output types: I2C and UART. It is compatible with Arduino, ESP32, Raspberry Pi and other mainstream control devices. Ideal for scenarios requiring extended working hours and high-precision time, such as astronomical observation timers, NTP servers, and outdoor wireless sensor time synchronization.
The differences between Gravity: GNSS Module with RTC Function and Gravity: GNSS Receiver Module:
Unlike the traditional Gravity: GNSS GPS BeiDou Receiver Module - I2C&UART, which is a single GNSS module with high power consumption and is only suitable for outdoor scenarios, this Gravity: GNSS Module with RTC Function offers a significant improvement.
The Gravity: GNSS GPS BeiDou Positioning Module with RTC Function has the ability to turn off the GNSS when not in use, leaving only the RTC module to maintain time, resulting in lower power consumption.
