SIRIUS PRO Surveying UAS
MAVinci SIRIUS pro is a fully integrated orthofoto UAS, which delivers orthofotos and three-dimensional elevation models with a high absolute accuracy of 5 cm (depending on the GSD down to 2 cm) without using ground control points. The GSD of the single images ranges from 1.5 to 20 cm. Combining MAVinci‘s precision timing technology with TOPCON‘s subcentimeter grade L1/L2 GPS/GLONASS RTK receivers this robust system stands up with a clever solution that helps realizing projects in a better and faster way.
Features:
- Save time and work more efficiently
- Get 5 cm absolute accuracy (depending on the GSD down to 2 cm) without GCPs in areas that cannot be accessed
- GSD from 1.5 to 20 cm
- MAVinci connector acts as a RTK base station, no additional base station required
- 100 Hz TOPCON sub-centimeter grade receiver
- L1/L2 dual frequency
- GPS/GLONASS
- Fully integrated RTK
Available workflows:
- Place your base station antenna on a point with known coordinates
- Post processing of the antenna reference point on site or after the flight
Placing GCPs and measuring them adds a significant amount of extra time and costs to your project. The time dealing with GCPs can be more than 50 % of the whole project time. We have also seen jobs where the area could not be easily accessed, or not at all. Without enough GCPs it was hard to match the accuracy requirements set by your customer – rendering projects uneconomical. It felt natural for us to remove the need for GCPs from your workflow.
Imagine you add 1000 GCPs to a project – uniformly distributed over the complete area. You determine their position and elevation 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. Combining MAVinci‘s precision timing technology with TOPCON‘s sub-centimeter grade receivers allows us to measure the camera position of each image so precisely that they can serve a similar function as GCPs. The MAVinci Connector acts as a RTK base station and transmits corrections to the UAV in real time. It‘s that easy!

Reproducability:
We have compared the ortho images from different flights and except different shadows and colors they fit to each other very well. Please review this reproducability by yourself here:
Comparison of different flights
The area that can be covered during one flight with SIRIUS depends on the Ground Sampling Distance (GSD: size of area represented by each pixel in a digital photo): Due to the low flight altitude high resolutions of 1,5 to 10 cm GSD are typically achieved. In one 40 min flight one can cover:
In case of computation of pseudo orthophotos (65 % overlap in flight and 20 % in side direction):
| GSD | AGL | Area per flight (pseudo Orthophoto) |
|---|---|---|
| 20 cm | 743 m/2438 ft | 18.2 km2 |
| 10 cm | 371 m/1217 ft | 9.97 km2 |
| 5 cm | 186 m/610 ft | 5.12 km2 |
| 3.2 cm | 119 m/390 ft | 3.20 km2 |
| 2.6 cm | 96.5 m/317 ft | 2.65 km2 |
| 1.6 cm | 59.4 m/195 ft | 1.62 km2 |
In case of computation of digital elevation model/true orthophoto (85 % overlap in flight and 65 % in side direction):
| GSD | AGL | Area per flight (true Orthophoto) |
|---|---|---|
| 20 cm | 743 m/2438 ft | 8.67 km2 |
| 10 cm | 371 m/1217 ft | 4.54 km2 |
| 5 cm | 186 m/610 ft | 2.25 km2 |
| 3.2 cm | 119 m/390 ft | 1.42 km2 |
| 2.6 cm | 96.5 m/317 ft | 1.13 km2 |
| 1.6 cm | 59.4 m/195 ft | 0.7 km2 |
Please note:
1. The actual imaged area is larger. The values given refer to the area that can be processed at full 3-D accuracy, rather than the area that was imaged. The border of the imaged area where 3-D quality decreases, is excluded from the given value. Values given are for optimal 3-D quality. Larger areas can be covered with compromises in 3-D quality. Reserve for low wind is included in the calculation.
2. Values are given for single flights. If the area exceeds the range of one flight, it will be split automatically, which increases the capacity to up to 30 %, due to reduction of the overlap on the border between flights.
For testing purposes we offer two demo datasets for download under the following address: ftp://mavinci.de
| 1. Work in mountain areas: Flight plan can automatically adapt to an elevation model. |
||
| 2. Cover areas that require more than one flight: Save up to 30 % flight time for large UAS missions: Flight plan splits up automatically and rejoins for post processing. |
||
| 3. Simple hand launch: The UAV is directly launched by hand, no catapult etc. is necessary. |
||
| 4. Land in areas where automatic landing is impossible: If obstacles or the small size of the area prevent automatic landing the operator can easily land autopilot assisted. The UAV is stabilized by the autopilot and manually controlled by simple up/down, left/right commands. |
||
| 5. Fly with a strong wind: The UAS is fully operational with wind of up to 50 km/h (approx. 7Bft) with gusts up to 65 km/h (approx. 8Bft). |
||
| 6. Temperatures: Operate the system at hot or cold outside temperatures from -20° C to +45°C. |
||
| 7. Rain: Use the UAS even under rain. |
||
| 8. Camera: Our high quality camera performs exceptionally well under low light conditions. |
||
| 9. Safety: Due to our high safety standards our UASs get flight permission e. g. in Germany, Spain and many other countries. |
