Holybro H-rtk M8p Gnss Series High Precision Positioning System Owner's Manual

H-RTK M8P GNSS

Descriptions

H-RTK M8P is the latest differential high-precision GNSS positioning system from Holybro. It uses a UBLOX M8P module, a IST8310 compass, and a tri-colored LED indicator. It also has a integrated safety switch for a simple and convenient operation.

Features

We have designed three models of H-RTK M8P for you to choose, each with different antenna design to meet different customer needs.

1. H-RTK M8P Rover lite (SKU12019) & H-RTK M8P Rover lite- 2nd GPS (SKU12026) – This model is lower cost, light weight, and has high performance, It can meet the needs of general DIY users. Due to the lower cost, this model can also greatly minimize the cost of large swarm drone projects such as swarm light shows. It has a integrated safety switch and a tri-colored LED indicator, and it is compatible with the open source Pixhawk series flight controller.
   
2. H-RTK M8P Helical (SKU12020) – This model uses a helical antenna, which has better performance than the lite version. This model can be used both on rover (aircraft) or as base station. The aluminum alloy shell design also has a integrated safety switch and a tri-colored LED indicator, and it is compatible with the open source Pixhawk series flight controller.
   
3. H-RTK M8P Base (SKU12021) – The board is the same as number 2 above, but it is equipped with a high-gain antenna. This model is best suited to use as base station. The search speed and positioning accuracy are the highest among the three models.
