Abstract: A method for determining a position of an object having a Global Navigation Satellite System (GNSS) receiver comprises receiving signals that are transmitted by GNSS transmitters positioned on board satellites positioned in view of the object; updating service data in the object, the service data including satellite clock data, satellite orbit data, satellite delay code bias data relating to delay code biases of the GNSS transmitters, and ionospheric model data indicating a state of an ionosphere; determining, based on the ionospheric model data, ionospheric delay data indicating corrections relating to delays of the signals, the delays of the signals resulting from passage of the signals through the ionosphere, and reception of the signals by the GNSS receiver; and determining a position of the object based on the signals, the satellite clock data, the satellite orbit data, the satellite delay code bias data, and the determined ionospheric delay data.

Abstract: In a method for controlling three single-phase motors and moving a platform in a direction of the normal, the motors are controlled by one three-phase converter, so that a first motor is operated between a first phase and a second phase of the converter, and a series connection or parallel connection of a second and third motor is operated between a second phase and a third phase of the converter. A platform is adapted to perform this method.

Abstract: In a method for optimizing control parameters, a transfer function of a transformer that includes a controller and a system to be controlled is ascertained experimentally. Quality criteria are derived from the transfer function of the transformer, the quality criteria being used for optimizing control parameters. Following a variation of the control parameters, a modified transfer function is calculated from the transfer function of the unmodified transformer without a new experimental identification.

Abstract: A method is for analyzing a drive system, according to which a transfer function of a target system in the drive system is determined by applying noise signals to the drive system. Several noise signals, which cover different frequency ranges, are successively applied as an input signal. In this context, the intensity of the noise signals may be optimized in steps, as a function of the covered frequency range, in order to improve the result of the identification of a target system in the drive system.
