Delta-FW70 Fixed-Wing UAV
& Intelligent Imaging Processing
Designed to Impress
Designed to provide professional aerial remote sensing and
mapping capabilities in one platform.
It features 4 separate
payload bays, capable of holding more than 375 square inches and
6 pounds of payload.
The Delta-FW70 Fixed-Wing UAV is an excellent aerial
platform for agriculture UAV operations. The
large airframe can accommodate a variety of sensors. HSE can integrate sensors
and autopilots to meet a variety of needs. The Delta-FW70 Fixed-Wing UAV is
intended for low cost, reliable, repeatable, day to day commercial operation in
harsh environments, poor weather, at night, and maritime use. It has the
capability of flight times in excess of two hours and range up to 20 miles in
poor weather, day or night.
The Delta-FW70 Fixed-Wing UAV has many camera and GPS
options for a downward facing camera for surveying, mapping, and agriculture.
Aerial imaging is all about the camera, and the Delta-FW70 Fixed-Wing UAV can carry
a large full frame mirrored DSLR NIR camera which offers the best in imagery and
field of view (FOV). The Delta-FW70 Fixed-Wing UAV is intended for low cost,
reliable, repeatable, day to day commercial operation. The key to covering the
maximum amount of area in the shortest amount of time is sensor size, not
megapixels (MP). Dont be fooled by high MP cameras with small sensors or you
will spend up to 5 times longer gathering imagery. You need to gather the images
as quickly as possible to maximize profits. No unmanned product at this time
gathers imagery faster or better for precision than the Delta-FW70 Fixed-Wing UAV
with the recommended camera.
This platform is large in size so that it can carry
larger sensors such as mirrored DSLR EO and NIR cameras, LIDAR, SAR, IR and
multiple sensors simultaneously. The larger platform is more stable in gusting
winds and high crosswinds and thus the imagery is much better without the need
for a stabilized gimbal. There is less rocking of the aircraft, fewer blurred
photos, and it can fly faster, higher and longer than smaller aircraft. The
bottom line is that for a given ground resolution the Delta-FW70 Fixed-Wing UAV is
outstanding for obtaining the most usable shots in the shortest amount of time.
It is set up to accommodate a variety of autopilots such as the 3DRobtotics
Pixhawk autopilot system which is capable of operating
the most sophisticated UAVs available, so learning to program the autopilot on
the Delta-FW70 Fixed-Wing UAV will carry over 100% into other commercial uses
because a variety of land, sea and air vehicles use the identical Pixhawk
autopilot. The foam core is 2+ lb density EPP which is far superior in impact
resistance than lightweight 1 lb. EPS. It survives very harsh environments and
most crashes. If damage should occur during a rough landing, repairs are
performed very quickly and easily with Superglue and adhesive tape. Repairs are
much, much easier than repairs to fiberglass aircraft.
Flight times of up to one hour can be achieved in
certain conditions. Flight times vary with wind speeds, direction of flight path
chosen by the pilot, spacing of the flight paths, temperature, the condition of
the airplane and its components, etc.
In conclusion, the Delta-FW70 Fixed-Wing UAV is a rugged,
easy to repair, inexpensive to operate, commercial/everyday aircraft with full
autopilot operation at a very reasonable cost.

HSE-CAM-AG1 is a Canon EOS SL1 DSLR Camera which is converted to NIR
type imagery. The conversion is to HSE specifications for
the best conversion to NDVI imagery by the leader in the industry LDP
LLC commonly known as maxmax.com. Feel free to peruse the Maxmax.com
website. Included with the camera is the Maxmax software to convert to a
simple NDVI. We recommend the use of aftermarket data processors because
there is a lot more to converting the imagery into usable data, but this
is good software to get started with to learn the process of NDVI
Included with the HSE-CAM-AG1 is:
- Canon EOS SL1 DSLR Camera body modified for NIR to NDVI imagery
- Canon EF-S 24mm Pancake Lens
- External Canon GP-E2 GPS Receiver
- Canon Hot Shoe / GPS Extension Cable made by Vello
- Remote Sensing Explorer Software
It is vital that the proper camera and lens be used for quality NDVI
conversion. There are several companies which specialize in cameras for
NDVI. We have tested many of them at great expense. Some cameras are
over $20,000. There are many different attributes which are critical to
obtaining proper imagery which can then be converted for use by many
types of softwares for NDVI. The camera is the most important part of
the selection process BY FAR. If you purchase a camera which is too slow
or with inadequate imagery you will probably purchase the wrong airframe
to carry it as well and you will have a total loss on your hands. The
camera and lens is proprietary.
- Distortion: It is very important that the lens has very little edge
distortion, and the filters are high quality glass which offer low
distortion throughout the image.
- GPS: The GPS must be fairly accurate for precision agriculture work,
but not sub centimeter accuracy. For volumetrics, then a higher
precision GPS is required.
- Camera resolution: The ground resolution changes with altitude, the
higher the flight, the lower the resolution. Starting with a very high
resolution camera allows higher and faster flights which reduce flight
times and thus operating costs. Resolution is all about the sensor size,
not the mega pixels. The chart below shows sensor sizes. Spending a
little more on a camera is a no-brainer! It will pay itself back in
shorter mission times after a few jobs.
- Weight: The weight of the camera is important because this determines
the size of the airframe necessary to lift it. Full frame cameras are
very large and heavy, and they can be supported with the Delta-FW70. The
advantage of the Delta-FW70 is that it is large enough to carry larger
cameras, but can also carry smaller cameras as well. It is a very
flexible airframe which allows a variety of equipment to be used.
- Lens: The lens of the camera is critical in terms of focal length and
to a lesser degree aperture. The focal length determines the altitude
that the UAV must fly to obtain a given resolution. After exhaustive
study we have determined the best price/performance lens. It has the
best blend of performance specifications to allow the fastest airspeeds.
It has very low distortion, especially edge distortion which allows for
fewer photos to be taken and fewer bad photos which must be discarded.
Size Comparison: The HSE APS-C (Canon) vs. typical point & shoot camera
1/2.3. Sensor size, not MP is the determining factor for imagery in NDVI
applications. APS-C (Canon) sensor is nearly 8 times larger than the
1/2.3 sensor. Dont be fooled by MP! This means that far fewer photos
need to be taken using the APS-C (Canon) format than the 1/2.3 sensor.
This translates to much shorter flight times and much faster data
processing times. Dont spend any more time in the field than is
absolutely necessary. Cloud cover and other weather conditions can spoil
data, and time is money!

A simple overview of how drones are used in the
farming industry to provide aerial imagery to create NDVI maps to
improve crop yields, reduce farming costs, protect the environment and
quantify crop damage insurance claims
The FAA recognizes that drones are essential to
increasing the productivity of farmlands. Small drones pose a limited
risk of injuring people, other aircraft, and property. Thus FAA approval
to use drones for farming is coming soon.
Probable FAA policies will revolve around safety, primarily collision
- Daylight operation
- LOS (Line of Sight) Operation
- 400' Ceiling
- Various safety devices, pilot and aircraft certifications, training,
safety protocols, etc.
Agronomists using drones to assist their
recommendations for fertilizer and pesticide application can improve the
bottom line to farmers by as much as 15%, and help the environment as
The world's farmers must increase yields to
feed the world's rapidly growing population. Drones are the latest
technological advancement to assist in increasing crop yields while
lowering pollution and costs.
Large fields and tall crops are extremely
difficult to assess from the ground. Drones provide aerial access at a
relatively low cost.
Agronomists operate the drones themselves or
hire local drone service providers to fly the fields.
Normalized Difference Vegetation Index (NDVI) is an extremely important
tool to determine if crops are stressed. NDVI compares bands of light to
accurately determine plant stress. This is state of the art technology.
Wikipedia explains NDVI in detail.
Photos directly from the onboard NDVI
compatible camera are unusable as is. The photos must undergo special
First, individual photos are stitched together
to make one large photo. Online processors are used for this operation
due to the high cost and complexity of the hardware and software.
The high quality single image is converted to a
NDVI image. NDVI processing software is inexpensive and easy to use
though the same online processors who stitched the photos offer this
The agronomist uses both the normal and the
NDVI images with more traditional methods to assess plant stress.
Plant stress can be detected well before it can be seen with the naked
eye as well as after obvious damage is apparent.
The agronomist then performs "ground truthing"
combined with other traditional methods to verify the NDVI data and
determine the cause of the stress. Often the agronomist physically walks
into the field and looks at the plants where the NDVI has identified
The agronomist then makes recommendations to
the farmer. If variable rate applicators are used by the farmer, then
varying rates of fertilizer and pesticides are recommended which reduce
treatment costs, protect the environment by reducing unnecessary
over-applications, and increase yields.
The three photos below are all derived from only one camera. Special
processing converts the image from the NIR (red) image that is taken by
the onboard camera to the "EO" (normal) image as well as the "NDVI"
image. Only the EO (Electro-Optical or "normal") and the NDVI images are
used by the agronomist. In the NDVI image the green areas are healthy,
the red are not. The area we are concerned with is marked with a blue
border. The area is a sod farm. In the NDVI photo the dark green areas
around the sod is trees. The large patches of red are areas which were
harvested. The red line down the middle is a dirt road. The small red
patches of red mixed into the healthy green area are problem areas. The
problem is confirmed by looking at the EO photo and by physically
walking into the field. There is no grass in the red spots. While you
see a low resolution image here, the resolution of the actual photo is
high enough to see individual blades of grass! The agronomist saves time
because if bare earth, standing water or another obvious problem is
identified using the EO image there is no need to walk the field. The
sod farmer in this case uses this data to identify excessively large
bare spots early on in the growing cycle to replant problem areas and
improve yield per acre.
Species Detection: Canadian Thistle
An NDVI map helped confirm the presence
of a Canadian Thistle infestation on this 122 acre corn field. A
flat rate herbicide prescription was applied to the entire
As shown in the aerial imagery,
inspections confirmed that only 0.6 acres required treatment. An
herbicide reduction of over 99% would have been possible with a
variable rate prescription, decreasing the overall environmental
impact and yield loss.
What is the Normalized Difference
Vegetation Index (NDVI)?
NDVI maps are useful for detecting
plant stress that may be invisible to the human eye. By
measuring the spectral characteristics of plants with remote
sensors, vigor can be assessed based on the amount of visible
light being absorbed in relation to the amount of near-infrared
light being reflected by the plant. The healthier the plant, the
greater the difference between the two spectral values.
