Here GPS
1

Good Morning,
What are the differences between the various GPS packages here?

2

Here and Here2 are the basic ones running Ublox M8N chip. The latest Here2 has CAN interface.
Here+ and Here+ V2 are the RTK setups. They have Ublox M8P chip.
All the GPS come with well designed 6cm ground plane.

thanks

RTK receivers come with ROVER and BASE. The first one is the whole kit(ROVER+BASE), second is only ROVER which goes on copter, third is the BASE which stays on ground to give RTK correction. Last one is the standard M8N GPS with CAN interface.
