About this product
The Here 4 is a professional High Precision Dual-band RTK Navigation module. It supports multiple GNSS options such as BeiDou, Galileo, GLONASS, GPS, and QZSS. The Here 4 utilizes advanced algorithms and multi-frequency DGNSS signals to quickly achieve an RTK Fix within seconds. This results in highly reliable positioning at an accuracy within centimeters. The Here 4 goes beyond being a simple GNSS module. It combines flight control and navigation functionalities into a single device. With 8 PWM or BDSHOT outputs, an RCIN, a Hotshoe, and a camera trigger, it offers a self-contained solution for accurate mapping and precise control capabilities.
Features
- LED embedded with ProfiLEDs. Built-in multiple display modes for notification or navigation signals. Display modes can be selected according to specific scenarios via parameters or onboard Lua Scripting.
- Here 4 uses multi-frequency DGNSS signals with advanced algorithms. This allows fast convergence to an RTK Fix, achieving more reliable and stable centimeter-level positioning.
- Powerful processing performance provided by a built-in STM32H7 chip. It offers real-time processing and data optimization, and Unmanned Industry standard AP_Periph Firmware.
- The tailor-made Dual-band antenna from Taoglas supports L1 and L5 frequencies. It features high gain, high sensitivity, and high stability.
- Built-in IMU. Through future firmware updates, Here 4 can achieve tightly coupled DGNSS-INS-fusing solutions.
- Equipped with u-blox F9P, a professional high-precision Dual-band RTK navigation module.
