Here3+ GPS Receiver

A sophisticated, high-precision GNSS module, the Here3+ GPS Receiver is intended for use in a variety of applications that demand precise location and navigation. By providing greater precision, quicker fix times, and support for several satellite systems, including as GPS, GLONASS, Galileo, and BeiDou, it improves on the capabilities of its predecessors. This makes it extremely flexible for use in robotics, agricultural machinery, autonomous systems that require accurate geolocation data, and drones and UAVs, among other fields.

An inertial measurement unit (IMU) and compass are integrated into the Here3+ for improved location estimation and stability control. Its sturdy exterior shields it from the weather, and its modest weight has little effect on the system’s overall performance. All of these features were included during its robust design process.

Multi-GNSS Support: The Here3+ GPS Receiver is designed to work with a multitude of satellite systems, including GPS, GLONASS, Galileo, and BeiDou. This wide-ranging compatibility ensures more reliable and accurate positioning by leveraging multiple satellites from different constellations.

High Precision & RTK Support: With Real-Time Kinematic (RTK) support, the Here3+ offers centimeter-level accuracy, making it suitable for applications where precision is critical, such as surveying, precision agriculture, and autonomous vehicle navigation.

Integrated IMU and Compass: An onboard Inertial Measurement Unit (IMU) and compass enhance the GPS receiver’s accuracy and reliability. These sensors provide additional data points for orientation, movement, and heading, which, when combined with GNSS data, result in improved position estimation and stability.

Fast Fix Time & Reacquisition: The Here3+ is engineered for quick satellite fix times and fast reacquisition, reducing wait times and improving efficiency in operations that require frequent stops and starts or operate in challenging environments.

Multiple Frequency Bands: It operates on multiple frequency bands, allowing it to mitigate the effects of ionospheric interference, leading to better accuracy and reliability in various conditions and locations.

Robust Design & Weatherproof: Built to withstand harsh environments, the Here3+ features a durable and weatherproof casing that protects the sensitive electronics from water, dust, and impact, making it suitable for outdoor and rugged applications.

Dual Antenna Inputs: Some models of the Here3+ may feature dual antenna inputs, enhancing orientation and positioning accuracy, particularly beneficial in applications requiring precise heading information.

Easy Integration: With its standard interfaces, the Here3+ is designed for easy integration into a wide range of systems. It typically includes connectors and communication protocols compatible with most autopilots, drones, and robotic systems.

Advanced Filtering & Algorithms: The receiver utilizes sophisticated filtering and algorithms to improve signal noise reduction, multipath mitigation, and overall GNSS data quality, leading to more reliable and stable positioning.

Wireless Connectivity Options: Some versions of the Here3+ may offer wireless connectivity options, such as Bluetooth or Wi-Fi, for easy configuration, data transmission, and firmware updates, enhancing usability and flexibility in deployment.

Update Rate: High update rates are supported, allowing for smooth and accurate tracking of fast-moving objects. This feature is crucial for dynamic applications such as drone racing, high-speed robotics, and vehicle navigation.

Low Power Consumption: Despite its advanced features, the Here3+ is designed to be energy efficient, ensuring minimal impact on the power resources of the host system, which is particularly important for battery-operated vehicles and devices.

Wide Application Range: Thanks to its versatile features and robust design, the Here3+ is suitable for a broad array of applications, including drones, UAVs, agricultural machinery, survey equipment, autonomous vehicles, and any system that requires precise and reliable positioning and navigation.

Each feature of the Here3+ GPS Receiver contributes to its performance and versatility, making it a top choice for professionals and enthusiasts alike who require high precision and reliability in their positioning and navigation solutions.

Under ideal circumstances, the relatively affordable CubePilot Here3+ GPS Module w/ iStand provides location accuracy down to the centimeter level and supports RTK mode. Compared to the original Here+, this variant has better resistance to dust and water, although it isn’t 100% certified waterproof.

The high data rate, upgradeability, noise immunity, and real-time functionality of the Here3+ GPS module are all made possible via the DroneCAN protocol. The system is now compatible with upcoming firmware updates and has switched to the DroneCAN 8 Mbit bus speed.

The Here3+ GPS module is driven by a dual-core STM32H757 CPU, clocked at 400 MHz, featuring 1 MB of RAM and 2 MB of Flash. Compared to the Here 3 model, which is powered by the STM32F302 CPU, this is a major upgrade.

To meet the needs of advanced navigation, the system also has an integrated motion unit (IMU) with a gyroscope, accelerometer, and compass. Mission Planner will provide access to future system changes.
