The Here 3+ GPS product is slowly being phased out of production and displaced by the newer Here 4 version .
Here 3+ is a high-precision GNSS system that supports RTK mode, built on the CAN protocol. It is designed to be resistant to dust and water sprays up to a certain level. Equipped with an STM32H757 processor, the Here 3+ receiver provides faster processing speed and better reliabilit
It has built-in sensors such as a compass, gyroscope, accelerometer and LED. It is based on the Chibios real-time operating system. Its open-sourced structure is ideal for developers with specialized requirements for their navigation systems
The new improved version of the Here 3+ receiver differs from its Here 3 predecessor in its processor and IMU senor, among other things. The new version has a dual-core processor clocked at 400 MHz with 2 MB of Flash memory and 1 MB of RAM. The IMU sensor has been changed to ICM42688 and RM3100. In addition, the receiver uses a new DroneCAM protocol that allows for 8Mbit/s speed. Learn about the types and distinctive features of the GPS GNSS Here 3+ in our article.
Key Features of GNSS Here 3+ with iStand
- Economical high-precision GNSS chip with support for RTK mode (a base station is required for RTK mode). Positioning with centimeter accuracy under ideal conditions,
- All-new design with improved visibility of indicator LEDs. Improved dust and water resistance (Water resistance is not guaranteed in all situations due to the complexity of the operating environment),
- Faster data transfer, expandability, immunity to interference by using CAN protocol,
- Equipped with a powerful STM32F302 processor in a real-time operating system. A framework developed by Hex provides additional system stability. It also supports future system updates.
- Supported by software for ground base stations. Future updates will be available through Mission Planner,
- Built-in complete set of Inertial Measurement Unit (compass, gyroscope and accelerometer) that meets advanced needs in navigation.
