Excellent results and high accuracy
+ Automatic take-off 

 by hand launch

After quick setup of the SIRIUS UAS, the operator chooses 

his area of interest and the desired Ground Sampling Distance (GSD). The fl ight planning software MAVinci Desktop 

automatically creates an individual fl ight plan. The fl ight 

plan can be calculated quickly in the fi eld or even in the offi ce before the mission starts. In addition, MAVinci Desktop 

has the ability to change the fl ight plan even when the UAV 

is currently fl ying.

One click in MAVinci Desktop transfers the fl ight plan wirelessly to the SIRIUS. For automatic take-off , the operator 

launches the SIRIUS by throwing it into the air without any 

additional catapult or bungee cord. The hand launch is safe, 

easy and comfortable. 

During the completely automatic fl ight the SIRIUS follows 

the predefi ned fl ight plan. Aerial images are automatically 

stored on board.

NIR camera payload

The NIR camera provides relative NDVI indices from minimum 

to maximum values in the image. It is a modifi ed version of 

the MAVinci visible range GX1 camera system achieveing the 

same high resolution images and high accuracy results. 

Single images can be processed into high accuracy orthophotos and 3D models.

The Normalized Diff erence Vegetation Index (NDVI) is a graphical indicator for analysis of vegetation conditions and 

photosynthetic capacity.

This camera can also capture images with green, red and near 

infrared (CIR) channels.

Air traffi c monitoring system 

ADS-B and FLARM are industry standards for portable collision avoidance systems for manned airplanes. They alert pilots if they get too close to another airplane or skydiver etc. 

also using ADS-B or FLARM. The MAVinci air traffi c monitoring 

system supports ADS-B, FLARM, MODE-S and MODE-C. It visualizes the positions of other nearby airplanes that are using 

ADS-B, FLARM, MODE-S or MODE-C in MAVinci Desktop and 

alerts the UAS Operator in case other air traffi c participants 

enter the UAS operation area.

SIRIUS pro: internal base station

As an alternative to an external RTK base station the SIRIUS 

pro UAS can be upgraded to an internal base station via internet upgrade. This allows the MAVinci connector to be used 

as an RTK base station in conjunction with the SIRIUS pro. The 

connector then has the ability to transfer RTCM messages to 

other rovers.

Hand launch

Simply hold the SIRIUS UAS above your head, release the 

engine and let the UAS start its mission. Using this way of 

hand launching the system you are far away from the turning engine and you do not need any additional equipment such as a catapult or bungee cord. 

Automatic operation from take off to landing

The SIRIUS UAS can be operated completely automatically 

without any interaction by the pilot from take off to landing. In addition the operator has the ability to land in areas 

where automatic landing is impossible via autopilot-assisted landing. SIRIUS is stabilized by the autopilot and manually controlled by simple up/down, left/right commands.

Completely flexible in severe weather conditions

Operate the system with hot or cold outdoor temperatures 

from -20° C to 45°C and fly in rain and strong wind: The UAS 

is fully operational in wind of up to 50 km/h (approx. 7Bft) 

and gusts up to 65 km/h (approx. 8Bft).

Cost efficient

The SIRIUS UAS has a long life cycle, performing more than 

200 landings with one body. The maximum flight time of 45 

min enables the operator to cover large areas in one flight 

and minimize down time between flights. Individual parts 

of the system can be replaced on demand instead of replacing the whole plane. Low operation costs of only 18 € per 

flight and the possibility of useing the system with only one 

operator further increases cost efficiency.

Interchangeable sensors

Switch between the visible range GX1 camera payload and 

the Near-Infra-Red GX1 payload between flights.

Upgrade SIRIUS basic to pro via internet

SIRIUS basic is upgradable to SIRIUS pro via internet upgrade; 

no additional hardware changes are necessary. This gives 

our customers full flexibility to start the business with a professional reliable tool and upgrade later to SIRIUS pro, for 

example for mapping inaccessible sites with high accuracy 

without the need for GCPs.

On-the-field quality check 

Some of the jobs you will do with the UAV may be in remote areas. A long journey used to be necessary to reach 

your area of interest. With our quality check function you 

can verify within minutes the quality of the data set you 

have acquired directly on the field. This function checks the 

overlap of the individual images and indicates sufficient 

overlap with green color. Even tiny details are visible in the 

preview. In addition, you can process a quick preview image 

and DEM if you want to analyze the data more thoroughly 

before heading back to your office.

Transport

The SIRIUS UAS is a light-weight system with a small pack 

size. All equipment fits into one single box with a total 

weight of about 20 kg. The transport box is made of robust 

aluminum and especially designed for permanent commercial use. It protects the UAS perfectly during transport and is 

resistant to corrosion, weather and temperature influences.

Simple and flexible use

Air traffic monitoring system 

ADS-B and FLARM are industry standards for portable collision avoidance systems for manned airplanes. They alert pilots if they get too close to another airplane or skydiver etc. 

also using ADS-B or FLARM. The MAVinci air traffic monitoring system supports ADS-B, FLARM, MODE-S and MODE-C. 

It visualizes the positions of other nearby airplanes that are 

using ADS-B, FLARM, MODE-S or MODE-C in MAVinci Desktop and alerts the UAS Operator in case other air traffic participants enter the UAS operation area.

Airspaces Maps

As a supplement to traditional ICAO airspace maps printed 

on paper, MAVinci Desktop visualizes digital airspace maps. 

They indicate by color wheter it is legal to fly in this airspace. 

MAVinci Desktop alerts the UAS operator that the SIRIUS 

UAS in nearing a restricted airspace.

SIRIUS has a wireless data link for up to 4 km line-of-sight 

range (actual frequency and range depends on your 

local regulations) and an additional RC transmitter with a 

2.4 GHz ISM link for manual backup control with a range of 

up to 3 km. The manual backup control link is independent 

of the autopilot to minimize the risk of radio link failure.

The flight planning software MAVinci Desktop shows status data of the UAV during the flight for example RC link 

state, GPS state, position of the UAV and battery levels. In 

addition the altitude of automatic operation can be limited (e.g. to 150 m).

To minimize possible damage to the UAS and to increase 

the safety of the system, the UAS performs special 

emergency actions if necessary:

• In case of engine failure (e.g. due to low battery level), 

 the autopilot continues to stabilizes the UAV attitude 

 and descents to prevent a crash.

• The operator can send a “return home“ command. 

 The UAV will then come back to the ground station.

• Actions to be performed in case of emergency (e.g. 

 GPS loss or link loss) can be configured via MAVinci 

 Desktop: The SIRIUS UAS will e.g. return to takeoff 

 position on RC-link loss or circle down to leave the 

 airspace on GPS loss. 

Electric engine safety button

Before the UAS is launched, the electric engine is locked 

and unable to start accidentally. A special release button on 

the side of the UAV body enables the operator only - and no 

other person - to release the electric engine and activate it 

shortly before launching. After landing a push on the safety 

button again locks the engine and secures the system.

Security features 

and emergency actions

Ensuring the safety of the system is one of our main objectives. 

Therefore we have implemented several features to protect you and the people around you:

18

Safety first
Watch SIRIUS live 

during the fl ight!

Autopilot assisted manual control 

Automatic take-off , fl ight and landing are innovative and 

very useful features. When using the UAS in the fi eld, unpredictable things such as rescue helicopters passing your 

fl ight area, can occur. It is therefore very important that the 

operator is able to interrupt the automatic fl ight of the UAV 

at any time to steer the UAV manually.

Our autopilot assisted manual control mode enables the 

operator to control the UAV assisted by the autopilot. In this 

mode the UAV is stabilized by the autopilot. The controller 

steers the UAV with simple up/down, left/right commands. 

The autopilot assisted control is very easy to use and can be 

learned within minutes. In addition the UAV always stays in 

the range of sight when in this control mode. Some countries do not permit the operation of UAS without the option of manual control. The assisted manual control mode 

enables you to operate your UAS legally in these countries 

without learning full manual UAV control.

Terrain awareness

During fl ight planning MAVinci Desktop checks your fl ight 

plans for potential collisions with the underlying terrain 

model. If possible, it optimizes the fl ight plan in order to 

stay a constant and safe distance from the ground.

All these security measures enable our customers to 

obtain fl ight permissions in many countries.

Fly safely with

air traffi c monitoring!

Advanced Panasonic GX1 camera

Any UAV payload should be as small and light as possible 

but deliver high quality data at the same time. For this reason we integrated the Panasonic GX1 camera into our UAS. 

It is small and lightweight and has a 16 MP Live MOS sensor. 

The sensor‘s area is about 9 times larger than the 1/2.5“ sensors typically used in compact digital cameras. We mounted 

a Panasonic 14mm f/2.5 lens on the Panasonic GX1 camera. 

The focal length of the lens is fi xed to increase the quality 

of the post-processing results. The calibration of the camera 

with the lens is optional.

Inherently stable UAV design

The SIRIUS UAS is shaped like a real airplane. This means it 

has three rudders for stabilization on 3 axes: elevator, side 

rudder, aileron. In this way the whole plane acts as a camera gimbal to stabilize the camera in fl ight and increase the 

quality of the images. 

In addition, the MAVinci autopilot navigates the SIRIUS UAS 

precisely along the predefi ned fl ight lines. This ensures the 

correct overlap between the individual images, and a photogrammetric fl ight pattern. 

High Quality Results

* Values are given for single fl ights. If the area exceeds the 

range of one fl ight, it will be split, which increases the capacity up to 30 %, due to reduction of the overlap on the border

High resolution geo-information products

The area that can be covered during one fl ight with SIRIUS 

depends on the GSD. Due to the plane‘s low fl ight altitude 

high resolutions of 1.6 - 20 cm GSD are typically achieved. 

Flight planning with MAVinci Desktop and the precise navigation of the MAVinci Autopilot ensure correct image overlap and a photogrammetric fl ight pattern. 

Number of pictures per fl ight

The SIRIUS UAS delivers more than 2000 images in one 

fl ight, so that each point on the ground is covered by an 

average of 15 individual images. A large quantity of pictures 

contains a large amount of information, which further improves processing quality and accuracy.

Ground Sample Distance (GSD)

The GSD is the distance between the centers of two neighboring pixels in an aerial image measured on the ground 

(e.g. 10 cm GSD means the centers of two neighboring pixels are 10 cm apart from each other, when measured on 

the ground).

Optical image resolution 

Optical resolution describes the ability of an imaging system to resolve details in the object being imaged. Each 

component of the system (lens etc.) contributes to the optical resolution of the system, as does the environment in 

which the imaging is done.

The MAVinci SIRIUS UAS has an optical resolution of up to 

1.8 cm at a GSD of 1.6 cm. This diff erence corresponds to 

the natural limits set by the laws of physics.

Relative vs. absolute accuracy

Relative accuracy expresses the error of measurements (e.g. 

length, volume) within an elevation model independently 

of the absolute orientation of the 3D model in the global 

coordinate system.

Absolute accuracy expresses the position error of a reference Ground Control Point (GCP) and its corresponding coordinate in the 3D model. This error can be expressed in three 

ways:

Calibration error 

Calibration error expresses the diff erence between a reference Ground Control Point (GCP) used during processing 

and its corresponding coordinate in the 3D model. Calibration errors underestimate true errors because GCPs are not 

independent validation points, since they are used during 

processing of the UAV data and estimation of accuracy.

Cross-validation error

In cross-validation, a 3D model is calculated by leaving out 

one GCP. This procedure is iterated many times, each time 

leaving out another GCP. During each iteration the discarded GCP is used as an independent validation point to calculate the accuracy of the 3D model. The resulting cross-validation error is a reliable measure of accuracy. 

True error 

True error expresses the diff erence between a reference 

Ground Control Point (GCP) that has not been used during 

processing and its corresponding coordinate in the 3D model. To determine true error, a set of reference GCPs are needed that are used only to measure errors, and that have not 

been used as supplementary information during post-processing at all. 

How do we defi ne accuracy in our data sets?

For SIRIUS classic or basic data sets in which no RTK was 

used, we specify the cross-validation error. When we analyze 

SIRIUS pro RTK data sets we specify the true error because 

no GCPs have been used during processing.

Resolution is not Accuracy!

The diameter is 100 cm in the original size.

24
Example with 1.6 cm GSD.

25
During photogrammetric orthophoto and DEM computation, the location of the GPS receiver of the UAV is used for 

geolocating the fi nal model if no ground control points are 

available. Depending on the region of operation, the error 

of the GPS ranges between 2.5m (with SBAS available, e.g. 

Europe, USA) and 15m (no SBAS, e.g. South America, Africa) 

in X and Y and about 50% more in Z. This error will also be 

present in the fi nal model. This means the fi nal DEM can be 

shifted, stretched, rotated, and twisted by this number of 

meters.

All of these errors can be reduced to the range of centimeters by using ground control points. This is how you work 

with SIRIUS classic and basic. The rule of thumb for accuracy 

in this case is: Accuracy is in the order of twice the Ground 

Sampling Distance (GSD) in x and y directions and three 

times GSD in the altitude of the 3D model.

However, sometimes it is too much eff ort to use GCPs, or 

it may be impossible for some missions, whether because 

entry to the mission site is restricted, or placing GCPs would 

interfere with the activity on that site or it is simply too dangerous to enter the site.

For these situations MAVinci has developed SIRIUS pro. Its 

absolute accuracy is down to 1.6 cm in x,y/ 2.7 cm in z depending on the GSD. Combining MAVinci‘s precision timing 

technology with Topcon‘s sub-centimeter grade L1/L2 GPS/

GLONASS RTK receivers allows us to measure the camera 

position of each image so precisely that they can serve a 

fuction similar to GCPs. 

Imagine that you add 1000 GCPs to a project – uniformly 

distributed over the entire area. You determine their positions and elevations to within a few centimeters and add 

them to post-processing. Averaging over one thousand 

centimeter-accurate points will give you amazing results. 

We are placing those one thousand points in the air - so you 

do not have to place them on the ground. 

MAVinci‘s precision timing technology

Besides GNSS accuracy the main factor infl uencing the accuracy of the fi nal DEM and orthophoto is knowledge of the 

exact point in time when an image was taken. Since SIRIUS 

fl ies (without wind) at a speed of about 18 m/s, even a small 

timing inaccuracy of about 100ms would cause an additional error of 1.8 m. For this reason the SIRIUS pro UAS benefi ts from the combination of the MAVinci precision timing 

technology and the new Topcon GNSS receiver which results in a sub-millisecond timing accuracy. 

Diff erent data sets match due to high accuracy

Another benefi t of the high accuracy of SIRIUS pro is that 

diff erent data sets from two diff erent fl ights and even two 

diff erent sensor payloads will match perfectly.

bringing them together in a virtual environment:

• Fast visualization

• Draw break lines and reference points in a 

 3D environment

• Perform volume analysis

• Real time calculation of elevation contour lines, 

 slopes and slope directions

• Direct export to CAD

Virtual measurement

Surveyors scan the terrain they want to measure and search 

for lines and specifi c points that allow them to describe the 

topography. These lines and points are carefully chosen, and 

the process is very diffi cult to automate. With Virtual Surveyor you can execute this process in a virtual environment. 

Thus you can use your surveyor's expertise and choose 

the points and lines that describe topography best.

Volume analysis

Virtual Surveyor allow you to use all points in a UAV elevation 

model and to perform volume calculations. Start by delineating the area of which the volume is to be reckoned, then 

let the software perform a fast and accurate calculation.

Fast visualization

Instead of reverting to standard communication strategies 

such as sketches, stills and pre-rendered animations, you can 

communicate your projects using an interactive 3D visualization. Orthophotos and elevation models can be combined 

into a 3D environment using Virtual Surveyor software. The 

pictures below show models of planned noise barriers as 

well as road furniture (guard rails, lights) that were imported and correctly positioned along the highways. In the resulting 3D environment, users can choose to navigate freely 

to any viewing point or fly or drive along predefined routes.
