Latest Patent Applications

One of Oertel's notable patent applications is titled "Method for Tracking GNSS Signals with a Control Loop Used Only for Phase Control and a Control Loop Used Only for Doppler Frequency Control." This method involves tracking GNSS signals using a GNSS receiver, a phase-based filter, and a frequency-based filter. The generator is controllable in epochs by the two control loops. The method includes several steps: creating a local replica with a channel generator, generating a first control variable in the form of a phase exclusively with a phase-based filter of a first control loop, generating a second control variable in the form of a Doppler frequency using only a frequency-based filter of a second control loop, updating the replica under the control of the generator, and repeating the process to update the replica.

Another significant application is for a "Method and Device for Creating a Digital Map." This method includes receiving first training data sets and generating second training data sets through a generative neural network. The process involves determining a second, perturbed image of the same surrounding area for each first image. The digital map is created by merging surrounding area images based on position descriptions using a scan matching method that includes a further neural network.
