Convert your Phantom 4 Pro v.1 /
v.2 / Advance into a PPK system.
Easy integration without the
need to open or modify your
Drone.
Description
The X5 PPK Module for Phantom 4 Pro is a-non intrusive GNSS adapter system to
connect to a DJI Phantom 4 Pro v.1/v.2 or Advance Drone (not included).
Main Advantages:
Contains its own high quality GNSS Receiver module with state-of-the-art components
No need to open or modify your Drone (keep your Drone’s original warranty)
The X5 PPK Module attaches and disattaches in seconds
No Batteries required
Ultra-fast image triggering detector sensor
Lightweight microelectronics: 80 grams
Trigger Sensor:
A sensor installed externally on the P4P drone detects the triggering of each photograph
and records a time stamp in the log file of the MULTIBAND X5 GNSS module. Timestamps
are extracted from the module after flight and combined with the in-flight imagery as
centimeter-accurate position geotags (geotagging) using various specialized software
options available on the market. The new X5 GNSS Module is a centimeter-accurate
multiband GNSS system for UAV mapping.

NEW HIGH PRECISION X5 GNSS RECEIVER:
The X5 GNSS receiver module is a multiband GNSS system, with centimeter precision
for UAV mapping.

METTATEC X5 App
The app is a user-friendly software for configuration and data collection that is available for
Android (iOS version currently being developed). Supports several coordinate systems. With
METTA X5 App, you can control all the features of X5 GNSS receivers. Our Beta Testers will
receive via email a link to download the app that is in beta version.
PPK Flight Operation Requirements:
For integration is required:
1. One GNSS X5 PPK Module for Phantom 4 Pro
2. One Drone: DJI Phantom 4 Pro v1/v2 or Phantom 4 Advance (Not included)
3. One RINEX compatible GPS Base Receiver (Not included)
4. Multiband GNSS UAV Antenna (Not included)*
*Compatible with the Reach M2 Helicoidal Multi-band Antenna.

Installation on the Drone:
1. Attach the Module into the drone’s left side leg
2. Insert a MicroSD memory card into the GNSS X5 Module
3. Plug the Micro-USB cable into the USB slot of the P4P
4. Carefully insert the Trigger Sensor under the motor of the Drone's left front arm
5. Install the GNSS Antenna on top of the antenna mount by screwing it to the short
connector of the cable provided (unscrew the supplied fixing nut and save it, in
case there is one)

6. Firmly attach the Antenna Mount to the top of the Drone using the 3M Velcro
provided. The correct installation position of the antenna mount is just above the
location of the Drone camera. Once placed, validate that the propellers of the Drone
do not touch the support.
7. Connect the antenna cable to the X5 GNSS module. Be careful not to block the
view of the Drone's anti-collision system
Drone Configuration
1. Turn on the Drone Phantom 4 Pro v.1/v.2 or Advance and its remote control.
2. Enter the DJI GO 4 App and activate the front red lights of the Drone
arms: Settings / MC Settings / Advanced Settings / Turn on Aircraft Arm
LEDs.
Topographic Survey Flights
Before Flight:
1. Program your flight mission following the instructions of the flight control application
you use: DJI GSP, Pix4D, DroneDeploy, MapsMadeEasy or others.
2. The provided MicroSD memory card (Max. 64GB capacity) MUST BE INSERTED in
the GNSS X5 PPK Module.
3. Turn ON the previously installed GNSS X5 PPK Module by connecting the Micro-USB
cable to the Drone.

4. Turn on your Phantom 4 Pro v.1/v.2 or Advance Drone.
5. Wait for the red LED of the GNSS X5 PPK Module light to be ON. It takes around
30 seconds to automatically start recording the data log file.
6. Once these verifications and recommendations have been made, you can now
proceed to fly the Drone and capture the flight mission photos.
After Flight:
1. By the end of each flight, the GNSS X5 PPK Module will already have recorded one
UBX file, so it is ready to be powered OFF without the need of stopping the
recording.
2. All data logs (UBX files) are automatically saved in the MicroSD memory card.
3. The data logs can be downloaded by extracting the MicroSD memory card or via WiFi
in the configuration mode.
As a result of the flight session and in order to perform a correct processing in PPK, you
must obtain the following data set:
1. Photos captured by the Phantom 4 Pro v.1/v.2 or Advance
2. RAW LOGS UBX of the X5 GNSS module of each flight performed
3. RAW LOGS (UBX or RINEX) from a ground-based GNSS receiver
4. List of Ground Control Point coordinates
With this information, you will be ready to process the data through different
photogrammetric software options.
Post Process - PPK
The final PPK (Post Processing Kinematic) mapping workflow can be performed using the
following software options. Each of them has its own steps to follow at the user choice.
This is a list of post-processing programs according to their degree of difficulty and
knowledge requirement in topography:
1. Toposetter 2.0 Pro (Trial Version / Paid Version)
2. REDtoolbox (Trial Version / Paid Version)
3. RTKLIB (Free Version)
4. Emlid Studio (Free Version)
Once the information is processed, you can import the image set into any mapping
software, such as Agisoft Metashape, DroneDeploy, Pix4D and others of your choice.
The UAV PPK App for event interpolation
The best online App for UAV PPK Event Interpolation. Corrects the millisecond difference
between the DJI drone's camera trigger, the Drone´s indicator LEDs and the event capture
in the GNSS X5 PPK Module for maximum accuracy, so ground control points are no longer
needed.

Two post processed files need to be input to the App: the RINEX post-processing file (.POS).
and the event file (.POS). And the precalculated delay time in seconds for DJI Drone LEDs:
0.3. The resulting geotagged file can be downloaded in CSV and TXT format, ready to input
into any popular photogrammetry software:
•Exports a photo geotagging file
•Exports a file with the flight path of the drone
Being an online service, you can use the App anywhere without the need for software
installations or license activation. Developed by our technological partner
SolucionesGeográficas (Geographic Solutions).
