Abstract: A signal generation system for signal simulation includes at least one data input, a pulse description word generator, a multi-frequency signal generator, and at least one radio frequency output. The multi-frequency signal generator is configured to simulate a multi-frequency global navigation satellite system signal. The pulse description word generator and the multi-frequency signal generator are assigned to the data input in order to process data received via the data input. The pulse description word generator and the multi-frequency signal generator are configured to generate an output signal based on at least one instruction for a certain generator behavior of the pulse description word generator and/or the multi-frequency signal generator. The at least one instruction is encompassed in the data received. Further, a method of signal generation is described.

Abstract: A system for measuring inter channel latencies between more than one transmission channel, comprises a signal source module configured to provide at least one signal. The system also comprises at least two transmission channels assigned to the signal source module, wherein signals propagate through the at least two transmission channels. The signals have a modulated global navigation satellite system (GNSS) waveform. Moreover, the system has at least one switch module assigned to the at least two transmission channels. Further, the system comprises at least one GNSS receiver module assigned to the at least one switch module. The at least one switch module is configured to connect an input of the at least one GNSS receiver module to each single transmission channel. The GNSS receiver module is configured to determine at least one of a time delay and a phase difference between the at least two transmission channels.
