2 Overview
The SkyHopper PRO offers a bi-directional Data Link specifically designed for commercial and
industrial drones, and provides the best solution for fleet 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 benefit 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
configurable 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 configuration, where 10% of available BW is allocated for
uplink and 90% is allocated for downlink.

6 TDMA
Time Division Multiple Access (TDMA) is a channel access method for shared medium networks. It
allows several units to share the same frequency channel by 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.
User Manual
Page : 18 / 31
7 PTP (Point-to-Point)
A PTP network is a radio link between 2 SkyHopper Pro units. The configuration (frequency and
profile) of both units must be the same with only one difference - one unit is configured as a Remote
Unit while the other unit is configured 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 finding 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 predefined as part of the profile configuration. 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.
Figure 5: Transmit frames of the remote unit and controller unit from Power Up
Note: A viewer unit acts like a Controller unit but with one major change, it does not transmit and
only receives.

9.2 Connecting the Antennas
Antennas for installation vary in size, shape, requirements and mounting methods. The antennas
should be as close to the SkyHopper Pro as possible and can be connected to it directly.
Cables should be chosen according to their attenuation (lower attenuation gives better results)
and flexibility (according to the path they pass through). Each cable should have an MMCX Male
connector on the SkyHopper Pro end, and a connector matching the antenna’s connector on the
other.
9.3 Connecting the Power
SkyHopper Pro has a dual power feed enabling hot-swap battery replacement during operation.
CAUTION – Powering up a SkyHopper Pro without connecting the
antennas can cause irreparable damage to the 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 flight controller.
The Pixhawk flight 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.
1. SkyHopper Setup
The first stage is to setup the SkyHopper link to enable the UART interface on the link. The
configuration should be setup on both units (Remote/Aerial and Controller/Ground).
Figure 10: Web GUI advanced configuration
In the advanced configuration 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
2. Physical connection
After the units are configured, the Pixhawk flight 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 flight controller and the serial cable to the unit.
User Manual
Page : 29 / 31
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.
3. UART to Ethernet
There is an option to configure the system to work with a UART-to-Ethernet configuration, 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.
