The 15th edition of the European Satellite Navigation Competition (ESNC) entered its decision phase! With 266 complete submissions from 40 countries the competition attracted new business ideas worldwide. The DLR Special Prize has been awarded as part of the European Satellite Navigation Competition (ESNC) for many years now.
The Top 3 finalists of the DLR Special Topic Prize 2018 with the title “GALILEO for Safe & Secure Systems” amongst more than 50 entries are
Finalist: GNSS Spoofing Detection and Signal Quality Checks
Spoofer – Safe by Design
In the near future autonomous vehicles like UAVs and autonomous ships and cars will become commonplace. They will use GNSS for navigation in addition to “sense-and-avoid” capabilities. However, GNSS is vulnerable to both environmental effects (including multipath reflections and local interference) and malicious attacks. Deliberate jamming from so called PPDs (Personal privacy devices) is a real menace, and spoofing – where GNSS signals are transmitted deliberately to deceive receivers – is now being reported in the real World. This will increase with the availability of low-cost Software-defined (SDR) GNSS signal generators.
The innovative solution presented uses algorithms that can easily detect spoofing and other impairments. Its approach processes GNSS signals in the frequency domain with an innovation that significantly reduces the processing load. While most receivers provide three correlation points per satellite, this product provides the equivalent of 250,000 correlation points for every visible satellite in real time. This means the signal quality received can be established before the signals are used, and spoofers are spotted based on the presence of multiple correlation peaks.
Finalist: Automatic Mowers Capable of Drawing on Lawns
The idea is to use an automatic robot-mower equipped with a GNSS receiver and actuators for the blades to easily reproduce designs of any type or form (commercial logos, football team logos, etc) on lawns.
It will be possible to create two or more shades of colour using variations in the height of the cut grass, changes in the fold of the grass, or different fertilizers that can change the colour of grass.
This will make it easy for operators to upload an image in a specific front-end application, at which point the mowers can start operating autonomously on the field.
The mowers are geo localized and know what to do at each point of a field. Each point can thus be compared to a pixel of a photo. Any kind of logo or trademark can be reproduced on grass. The job can be done by only one mower or divided among multiple units working and communicating together. The idea allows operators of sports events and advertisers to access new ways of communicating in a "green" way! Thanks to this solution, it will be easy for many operators of sports events to leave a temporary message on the pitch (football, golf, etc). This will open up new perspectives and opportunities in advertising while making the playing field an important place for communication.
Finalist: Galileo Receiver for Small Satellites Application
Small satellites and cubesats in particular are transforming from educational projects into professional tools for delivering commercial services or performing scientific observations and measurements. For these small satellite missions there is a need for sensors which can provide exact timing and positioning information in orbit at any given moment. In Low Earth Orbit (LEO) there are several sensors in use, including sun sensors, star trackers, magnetometers, gyroscopes, and Galileo L1 and L5 receivers. The ideasholder has developed an advanced processing algorithm for sensors like these to achieve higher precision, safety, and spoofing resistance. In connection with other attitude determination sensors there will be one compact unit which can provide high-precision attitude data, timestamps, and exact positions for small satellites in orbit. This unit can also be used in UAVs or pseudo-satellites (stratospheric platforms). To contribute to the rapidly expanding smallsat market with high-precision units, the ideasholder is using GNSS receivers for orbit positioning and timing together with other sensors for attitude determination.
