2 Overview
The SkyHopper PRO offers a bi-directional Data Link speci cally designed for commercial and industrial drones, and provides the
best solution for eet management and autonomous UAV systems. By employing leading wireless technologies, SkyHopper PRO
delivers long range and Non-Line of Sight (N-LOS) communication that supports broadcast, multicast and unicast transmission
modes.
SkyHopper PRO supports Point-to-Point and Point-to-Multipoint communication, thereby enabling various modes of operation
such as communication for multi-drone operations and drone communication to multiple ground units and viewers (receivers).
An additional bene t of your SkyHopper PRO is that it offers Control, Telemetry and Payload all in one RF channel. No need for
separate solutions for each, no need for excess items to weigh down your drone.
Figure 1: SkyHopper PRO
2.1. Network Topologies and Applications
2.1.1. Point-to-Point (PTP)
A Point-to-Point system includes 2 units, with the bandwidth ratio between the two units con gurable according to the application. It can be symmetric when a full duplex communication is required (50% to each unit) or asymmetric up to 10% to
one unit (Controller or Remote Unit) and 90% to the other unit (i.e. drone/robot that transmits video to the ground/controller
unit and that controls the camera).
Example for an asymmetric link: 6Mbps con guration, where 10% of available BW is allocated for uplink and 90% is allocated for downlink.
Downlink 10% = 0.6 Mbps
Downlink 90% = 5.4 Mbps
Uplink 10% = 0.6 Mbps
Uplink 90% = 5.4 Mbps

6 TDMA
Time Division Multiple Access(TDMA) is achannel access methodfor shared medium networks. It allows several units to share
the samefrequency channelby dividing the signal into different time slots. The units transmit and receive on the same frequency
in a synchronized manner. Every unit transmits in its own dedicated time slots. On the other time slots said unit receives the transmission sent by the other units that are members of the same network (which are also transmitting on their own dedicated slots).
TDMA requires a synchronization system. The system is synchronized internally, externally or via GPS (synchronization varies
between topologies and method used).
The SkyHopper PRO unit uses TDMA regardless of the application type, PTP or PTMP.
7 PTP (Point-to-Point)
A PTP network is a radio link between 2 SkyHopper PRO units. The conguration (frequency and prole) of both units must be
the same with only one difference - one unit is congured as a Remote Unit while the other unit is congured as a Controller Unit.
The Remote Unit works with its internal clock and synchronizes the Controller Unit. After power-up, the Remote Unit starts transmitting regardless of link status. The Controller Unit however, does not transmit and stays in Rx mode, trying to acquire synchronization by nding a preamble (synchronization pattern). As soon as the Controller Unit recognizes the pattern, it starts to transmit
according to its allocated time slot.
The transmission bandwidth ratio is predened as part of the prole conguration. It can be symmetric when full duplex communications are required (50% to each unit) or asymmetric up to 10% to one unit (remote or controller) and 90% to the other unit.

Appendix D – Setting up a Pixhawk based system
In this section we will describe how to setup a network for a drone using a Pixhawk ight controller.
The Pixhawk ight controller uses a UART interface and runs the MAVlink protocol over it. SkyHopper PRO has an RS232 interface which is similar in its word structure to RS232 but there is a difference in the voltage levels.
D. 1. SkyHopper Setup
The rst stage is to setup the SkyHopper link to enable the UART interface on the link. The con guration should be setup on
both units (Remote/Aerial and Controller/Ground).
Figure 10: WebGUI advanced con guration
In the advanced con guration screen:
1. Go to the UART section
2. Enable the UART and choose UART-to-UART
3. Setup the Baud rate to 57600
4. Choose protocol C
5. Reboot the unit
6. Repeat on both Remote and Controller units
D.2. Physical Connection
After the units are con gured, the Pixhawk ight controller should be connected to the unit.
On the remote (Aerial) unit Use the Pixhawk adapter accessory which can be purchased on our website and connect it to
the serial cable provided with the SkyHopper PRO unit. Connect the adapter to the Pixhawk ight controller and the serial
cable to the unit.
On the controller (Ground) unit, connect the D-Type/9-pin accessory adapter to the serial cable supplied and connect the
cable to the unit. If the Tablet/PC has a serial port, connect it directly, if not, a USB-RS232 adapter should be used.
D.3. UART to Ethernet
There is an option to con gure the system to work with a UART-to-Ethernet con guration, which eliminates the use of the
serial cable on the Ground Unit.
Please refer to the UART-to-Ethernet Connection Guide online at www.skyhopper.biz/prosupport.
