Here4 Multiband RTK GNSS

Here4 is a professional High Precision Dual-band RTK Navigation module.

It supports multiple GNSS options such as BeiDou, Galileo, GLONASS, GPS, QZSS.

The Here4 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 Here4 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.

WHAT'S NEW?

• Equipped with u-blox F9P, a professional precision dual-band RTK navigation module.
• 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 L1and L5 frequencies. It features high gain, high sensitivity, and high stability.
• *Blue version supports Drone-ID.
• 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.
• The Here 4 module is 16 x 68mm and 60g.
• 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.
• CAN FD, real-time, and high transmission rate.
• Built-in IMU. Through future firmware updates, Here 4 can achieve tightly coupled DGNSS-INS-fusing solutions.

CENTIMETER LEVEL HIGH-PRECISION POSITIONING:

Built-in STM32H757 dual-core processor. The combination of the RM3100 magnetic compass and ICM42688 sensor has better performance in more applications.

MORE ONBOARD COMPUTE AND MEMS:

Built-in STM32H757 dual-core processor. The combination of the RM3100 magnetic compass and ICM42688 sensor has better performance in more applications.

INTEGRATED MODULE WITH MULTIPLE FEATURES:

Here4 is more than a GNSS module. It has both flight control and navigation capabilities. Fitted with 8 PWM or BDSHOT outputs, an RCIN, a Hotshoe, and a camera trigger, accurate mapping has never been more self-contained.

SUPPORTS FURTHER EXPANSION/CUSTOMIZATION:

The reliable DRONECAN FD communication protocol ensures fast (8Mbps) and stable transmission. Based on the AP-Periph open-source platform, users can better carry out further development and customization.
