The UX5 HP aerial imaging solution
The Delair UX5 HP aerial imaging rover is an unmanned aerial vehicle (UAV). An unmanned aerial vehicle is a
generic term, and refers to an aircraft that is operated remotely. The UX5HP aerial imaging roverfollows a
pre-programmed path where takeoff, flight, and landing require minimal human intervention. If required,
the crew operating the aircraft from the ground can intervene to change the flight path or to land. In some
cases, such as communications failure or loss of GPS signal, a pre-programmed intervention is
automatically activated to re-establish signal loss or to terminate the flight early and complete a safe
landing.
The UX5HP aerial imaging roverholds a camera that takes aerial images over the defined area. During the
flight, all pictures are acquired at a specified height, along parallel lines with specified overlap between the
image exposures. At the same time, precision GNSS-based position information is recorded during a
postprocessing kinematic (PPK) survey to achieve highly accurate position information for the captured
images. When processed in image processing software such as Trimble Business Center software, the PPK
data produces high absolute accuracy deliverables.
About postprocessed kinematic surveys
A postprocessed kinematic survey enhances the accuracy of position data derived from satellite-based
positioning systems by using data from at least two GNSS receivers: a base (reference) receiver and a rover
(moving) receiver.
The base receiver remains stationary at a site with precisely known coordinates. The coordinates of the
rover are unknown. They are determined relative to the reference position using measurements recorded
simultaneously at the two receivers. The positioning accuracy obtained with this technique is usually
centimeter accuracy. This is mainly because the measurements of two (or more) receivers simultaneously
tracking a particular satellite contain more or less the same errors and biases. The shorter the distance
between the two receivers, the more similar the errors. By calculating the difference between the
measurements of the two receivers, common errors are removed and those that are spatially correlated
are reduced, depending on the distance between the reference receiver and the rover.
For a PPK survey, the data collected by the rover is processed and corrected after the measurements have
been made. This provides the following advantages compared to a real-time kinematic (RTK)survey:
lMore accurate results as the data throughput is not limited by the real-time communication link.
lCommunication link-related problems, such as signal obstruction or limitation of coverage, are
avoided.
lNo accuracy degradation due to data latency.
lMore accurate results due to more flexibility in editing and cleaning of the collected GPS data.
Typical applications
Image acquisition can be used for:
lOrthophoto creation
lDigital Elevation Model (DEM) or Digital Surface Model (DSM)
lPhotogrammetry

Projects, blocks, and flights
Aproject consists of all activities needed to acquire aerial imagery of your area of interest. The area of
interest consists of one or more blocks and blocks are added to flights. A flight can cover more than one
block, as long as the total flight time is less than the maximum flight time. If the estimated flight time for a
block exceeds the maximum flight time, the block can be split into smaller parts.
Projects, blocks, and flights can be copied so it is easy to set up similar projects or flights. Copy blocks to
easily repeat flights at different heights or to redo a flight regularly, for example to track changes or
progress over the block area.
Note – Block and flight planning are usually done in the office but must be validated in the field after
checking actual conditions.
For example, a farmer wants to aerially photograph his potato fields. The farmer has two potato fields,
located 500 m apart from each other. In his project, he creates a block for each field. One field can be
mapped in an estimated flight time of 20 minutes. But one field is so large the estimated flight time is 40
minutes. It cannot be mapped in one flight because the maximum flight time is 35 minutes. Therefore, the
farmer splits the block into two blocks. He could split the block into two equal blocks of 20 minutes, but
then that would result in a total of three separate blocks that have to be flown as three separate flights.
Instead, the farmer splits the larger block into one 10 minute block and one 30 minute block. Then the
farmer adds the new 10 minute block to the flight for the existing 20 minute block. The farmer can now map
both fields in two flights, each of 30 minutes duration.
Project phases
The typical phases of a project are:
lBackground map definition: In the office you can prepare the background map, adding details such as
avoidance zones.
lBlock definition: Define one or more blocks to be aerially photographed. You can specify the planned
direction the rover will fly over the block(s) in the office, but you must validate the block properties in
the field to take into account the actual environment.
lFlight definition: Prepare one or more flights to cover the block(s) and suggest the takeoff and landing
locations. If the flight preparation is done in the office, then you must validate the flight properties in
the field, including the selected takeoff and landing locations.
lFlight scheduling: Flight scheduling is completed outside of the Aerial Imaging software. Complete
checks for flight permissions, weather, and site suitability and schedule the flight. Before heading to
the site, check all equipment for any damage from previous flights and fully charge all batteries.
lPPK operation: If you need centimeter-level absolute accuracy the rover should operate with PPK. PPK
requires data from a reference station. This station can be a local base station (with or without a
precisely known position) that you set up before the flight or a network reference station, such as
CORS, that you access after the flight.
lFlight operation: Complete the flight checklist to ensure that the system is ready for the flight. After
launching the rover, monitor the flight using the ground control station. After the rover lands,
complete the post-flight checklist to transfer the flight data to the tablet.
lAnalysis and export: Analyze the flight and captured images to make sure they are synchronized and
then export the data in the appropriate file format for image processing.

Note – Some maintenance procedures are only available in the Aerial Imaging Tablet software.
Updating the eBox firmware
The Aerial Imaging software automatically checks that the eBox firmware is up to date when the connection
between the GCS and the rover is established during the flight checklist procedure. If firmware updates are
available you are prompted to perform an update. It takes about 30 minutes to update the eBox firmware.
To manually initiate a firmware update, tap Updating the firmware in the Maintenance screen (see
Performing maintenance, page 17). To check the firmware version, tap Checking the firmware version in the
Maintenance screen.
1. When you are prompted to perform an update, do one of the following:
lTo dismiss the update checklist, tap . The flight checklist is aborted because the software does
not allow you to fly when the firmware version is not in sync with the Aerial Imaging software.
lTo start the firmware update, tap . The update checklist appears.
2. When prompted, attach the modem to the GCS. Tap to update the modem firmware.
3. When prompted, connect the download cable to the eBox and the modem. Tap to update the eBox
firmware.
4. The eBox firmware update consists of several automatic steps. When the firmware has finished
updating, disconnect the download cable from the eBox and the modem.
Depending on whether the Update firmware checklist was started automatically or manually, either
the start of the flight checklist or the Maintenance screen appears.

Designing a flight plan to meet the project requirements
There are many factors that can influence the success of a project. Good project planning is one of them.
A carefully planned project will ensure that flights are executed safely and that the captured data can be
processed successfully.
The quality of a project’s deliverable is often linked to its accuracy, referring to the positional accuracy of
the final output result. A project is processed based on geospatial coordinates, which are automatically
acquired during the flight. The output result has a relative accuracy of several times the GSD.
The GSD (ground sample distance) specifies the distance on the ground represented by the pixel of a
captured image. It depends on the camera sensor’s pixel size and lens focal length. The smaller the GSD
value, the more detailed the images. The GSD and the height at which the rover flies are linked. The higher
the rover flies, the larger the distance on the ground represented by each pixel in the images acquired
during the flight.
Other factors that impact the final output result include PPK, ground control points (GCPs), image overlap,
and camera settings.
If you need centimeter-level absolute accuracy, the rover should operate with PPK. PPK requires data from
a reference station. This station can be a local base station (with or without a precisely known position) that
you set up before the flight or a network reference station, such as CORS, that you access after the flight.
The absolute accuracy can be much improved by using ground control points (GCPs) if PPK is not available.
A ground control point is an accurately surveyed coordinate location for a physical feature that can be
identified on the ground. Use at least 5 GCPs, which are evenly spread over the area of interest.
The percentage of image overlap allows processing software to correct for errors in the position and
orientation of the aerial images (a rover is a dynamic platform with position and orientation sensors that
are not that precise). Delair recommends having a forward and sideward overlap of 80% which gives the
most accurate results while minimizing flight and processing time. There are some cases where increasing
the overlap may be beneficial. Examples are when flying over dense tree canopy, bodies of water, or large
areas of sand or snow. These often have a shortage of identifiable features in the images that can be used
as tie points for the image adjustment.
Image overlap also varies with changing terrain elevation and features. Use blocks at different heights to
ensure the same level of overlap for all areas of interest (see the images below). The image on the left does
not take into account the terrain elevation, which results in a varying amount of overlap. The image on the
right does take into account the terrain elevation, ensuring the same level of overlap for all areas of
interest.
