Multipath discriminator module
|467 - Abstract:|
|The European Space Agency has developed a multipath discriminator module for navigation and communication systems, allowing accurate positioning determination and reducing the bit-error rate in data transmissions. The navigation system including this module is a part of the technology. The organization seeks license agreements and industrial partners.|
Description of the offer:
Numerous systems using distributed spectrum modulation have been developed and widely used for navigation, satellite and terrestrial communication systems, currently for third generation mobile phones (UMTS standard). However, these systems are often not precise enough for navigation applications due to the problem of multipath signals. Compensating methods for multipath telemetry have been developed, in particular for GPS receivers. These methods are not effective for being used with CBC signals, as defined in the UMTS standard and also (potentially) in the Galileo system. This module offers a technological solution for compensating multipath for systems using CBC signals. The multipath discriminator module includes:
- An input which receives navigation signals
- A sampler which supplies the sampling signal
- A sub-module which calculates an error signal
This module is combined with a navigation system.
Innovations and advantages of the offer:
In usual navigation systems, the measuring time of arrival is not accurate due to multipath signals. As a result:
- A decrease in localization accuracy regarding telemetry occurs.
- An increase of the error rate regarding data transmission occurs.
Domain of Application:
This invention can be used in several sectors such as the space industry, automotive industry, transportation of merchandise and communication - in particular for applications where accurate localization is required.
- Telephone related
- Data transmission
