Overview

The DroneCAN H-RTK F9P is the latest differential high-precision GNSS positioning system from Holybro. It has adopted the DroneCAN protocol for communication. It provides multi-band RTK with fast convergence times and reliable performance, concurrent reception of GPS, GLONASS, Galileo and BeiDou, and a fast update rate for highly dynamic and high volume applications with centimeter-accuracy. 

With the adoption of the DroneCAN Protocol, it has up to an 8 Hz navigation update rate, upgradeability, noise immunity, real-time features, and is more robust than UART due to its increased resistance to electromagnetic interference. It does not occupy any serial port of the flight controller, and multiple CAN devices can be connected to the same CAN bus via a hub.

The DroneCAN-F9P uses a u-blox ZED-F9P module, a BMM150 compass, and a tri-colored LED indicator, and is equipped with the STM32G4 processor running at 170 MHz with 512 KByte Flash and 96KByte RAM. It supports DroneCAN firmware upgrade via the DroneCAN GUI Tool. It is compatible with the open source Pixhawk series flight controller.

Features

We have designed two models of DroneCAN H-RTK F9P for you to choose, each with different size and antenna design to meet different customer needs. 

DroneCAN F9P Rover
The Rover model has a flatter profile and stronger water resistance. It uses a dual band patch antenna and comes with an integrated cable to connect to the CAN bus. It excels in spaces where there are few obstructions.
 
DroneCAN F9P Helical
This model uses a helical antenna, which has slightly better performance in space with obstructions than the Rover version. The antenna of this module can either be attached to the module directly or connected via a SMA cable, giving you the ultimate flexibility. It also has a UART2 port exposed, allowing you to do YAW/Heading (aka moving baseline).


This model can be used either on the rover (aircraft) or as a base station. However, when used as Base Station, RTK communicate with the Ground Control Station via USB, so the DroneCAN protocol is not used. You can consider using the standard H-RTK F9P Helical or Base for your Base Station.

Great stand for the price!
Size: Quad, Style: Glass Free Stand, Size: Quad, Style: Glass Free Stand
It is a great stand. I was able to put everything together myself. Just wanted to point out a couple of things here. I have 2, 27" flat montors and 2, 37" curved monitors. Now the description says it will go up to 27", but I was able to get the 37" ones on this stand also. You can put them side by side - they will fit, but make sure you don't go over the weight limit, so for mine, to be sure I didn't exceed the weight limit, I have the bottom of them sitting on the and foot of the frame itself. You will not be able to angle them inwards toward yourself if you have 37" curved monitors. This is what I was hoping to do I just needed an extra inch on each side to move them out, for now I will just leave them side by side. For assembly, because I was doing this by myself, I found it easiest to leave all the moveable parts loose and lay the monitors out on the floor face down in the position I wanted them in (NO CABLES). Then I took the mostly assembled frame and adjusted it to my monitors. I put the plates on the monitors and then slid the appropriate piece of the frame onto each plate, still leaving most parts slightly loose (giving myself just enough play to move things around when I stood it up). I then stood the frame up and firmed down all the fittings once I got everything where I wanted it. I then lifted the entire stand with monitors up onto my desk and then began plugging in all the cables and cords. I really like the stand and it is a great value for the price. It is very sturdy with my setup. I just wish it had about an extra inch on at least the bottom two arms, but overall, definitely a great stand. (sorry for the bad photo but these are my work monitors and I could not show what was on the screens)

Perfect! Level monitors, small footprint!
Size: Dual, Style: Glass Free Stand, Size: Dual, Style: Glass Free Stand
Perfect! This was the 3rd monitor stand I purchased this month. The others either were too bulky of a base and/or I could never get the monitors level! This is perfect! Was easy to assemble and it’s easy to move them & adjust tilt & spacing.

Sturdy with good finish
Size: Dual, Style: Glass Free Stand
Easy to set up. Good finish. Sturdy. Using 2 x 27" monitors . A bit difficult to align them seamlessly. Suggest getting monitor alignment aids together with this.

The best Quad Monitor Mount under $100
Size: Quad, Style: Glass Free Stand
Great monitor stand. I got the Quad. It's base is nice and you can put stuff on it unlike the other popular quad mount that is V shaped. You can get the monitors 98% aligned, then use gaffers tape for the last 1% (99% perfect, slight gaps that I couldn't fill). Strong, sturdy, tempered glass base, metal pole. And cheap price. This is the one to get for a quad setup. I stripped the bolt on the VESA monitor mount bracket and the seller took care of me. No worries.

Excellent stand
Size: Dual, Style: Glass Free Stand
I love the functionality of this stand! It is very durable and stable. It does not require any form of anchoring to hold monitors. I have two 27 inch monitors attached to my stand with no problems. The stand can be moved in various direction with little effort. Excellent stand if you are looking to enhance your office space.
