Here4 Multiband RTK GNSS with Coating is a professional-grade, high-precision navigation module manufactured by CubePilot. The coating is likely a reference to the "Blue version" which features Dron-ID support and enhanced durability/temperature resistance. 

The Here4 Blue Multiband RTK GNSS is a professional-grade navigation module by CubePilot designed for precision sUAS (small Unmanned Aircraft Systems) applications.

The Here4 Base (without antenna) isa high-precision GNSS RTK base station module from CubePilot designed for use with drones and autonomous systems. It is a standalone receiver unit that requires an external antenna to function as a reference station for centimeter-level accuracy. 

HerePro (without iStand) is a professional-grade, multi-band RTK GNSS navigation module designed for high-precision UAV and robotics applications. This specific package includes the main GPS unit but excludes the iStand mounting hardware, making it suitable for custom integrations where the standard stand is not required.

The HerePro USB Adapter Board is an accessory for the CubePilot HerePro GNSS module, designed to facilitate a seamless connection between the HerePro and external devices, primarily a computer, via USB. This connection is typically used for configuring the HerePro as an RTK (Real-Time Kinematic) base station or for firmware updates.

The Here+ Base (M8P) is a high-precision GNSS base station module designed by CubePilot for Real-Time Kinematic (RTK) positioning. It utilizes the u-blox M8P chip to provide centimeter-level accuracy for drones and other unmanned vehicles.
