Holybro H-RTK F9P High-Precision GPS Compass Module

H-RTK F9P is Holybro’s top of the range high-precision GNSS positioning system. It uses a UBLOX F9P module, a IST8310 compass and a tri-coloured LED indicator. It also has an integrated safety switch for a simple and convenient operation. This system provides multi-band RTK with fast convergence times and reliable performance, concurrent reception of GPS, GLONASS, Galileo and BeiDou, and fast update rate for highly dynamic and high volume applications with centimeter-accuracy.

There are three models of the H-RTK F9P to choose from, each with different antenna design to suit different applications:

H-RTK F9P Rover lite

This model is lower cost, lightweight, and has high performance. It can meet the needs of general DIY users. Due to the lower cost, this model can also greatly minimise the cost of large swarm drone projects such as swarm light shows. It has a integrated safety switch and a tri-coloured LED indicator, and it is compatible with the open source Pixhawk series flight controller.

H-RTK F9P Helical

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-coloured LED indicator. It is compatible with the open source Pixhawk series flight controller.

H-RTK F9P Base

In this unit, the control board is the same as the Heical version 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.

Standalone GPS VS RTK GPS:

Standalone is the standard GNSS practice, also known as Single Point Positioning. While using this method, there are no error corrections made. The GNSS satellites just provide you with the best signals available with an accuracy of around 1-3 meters. Real Time Kinematic (RTK) increases the accuracy of GNSS/GPS systems to centimeter-level, by using a base-station receiver setup at a known location and a rover that gets the corrections from the base-station or a network of base stations. RTK has historically been used primarily by surveyors and others who required precise positioning, and were able to afford expensive RTK systems. Now Holybro makes this same functionality affordable to hobbyists and makers.
