Máy phát tín hiệu IZT S1000 GNSS.
Máy tạo tín hiệu Signal Generator IZT S1000 GNSS Realtime Simulator là một thiết bị nhỏ gọn, đa kênh và hiệu năng cao cho kiểm thử GNSS. Tín hiệu điều chế GNSS được tạo bởi IZT S1000 GNSS theo thời gian thực với độ trễ cực thấp.
The IZT S1000 GNSS Realtime Simulator multi-channel, multi-standard functionality enables the generation, encoding, and modulation of RF signals for important global digital standards and simulates real-time impairments. It can be used to meet a wide range of challenging test requirements as well as to perform integrated automated
sequences to reduce time to market.
It is complemented by a software-based Satellite Constellation Simulator, which simulates the satellite orbits by using a sophisticated orbit integrator including modeling of environmental parameters such as satellite clocks, transmit power, antenna patterns, ionosphere, and troposphere. In addition, multiple types of signal interference, like jamming and spoofing, can be defined. To detect such disturbances for GNSS systems, the proven GIDAS system of our partner OHB Digital Solutions can be used.
Optional software modules can be used for the sophisticated simulation of interference signals on top of the GNSS signals including realistic simulation of channel power variations. The real-time RF signal generation is enabled by an FPGA implementation and a real-time interface between the IZT S1000 GNSS Realtime Simulator software and firmware. An additional real-time input interface is available in the software to offer HIL (Hardware-in-the-loop) scenarios.
For the most demanding applications, data can be streamed from an external Memory Extension directly into the FPGA via dual Gbit LAN. The 10 Gbit optical LAN interface is reserved for the GNSS. All kinds of signals for radio testing and any I/Q signals of variable sample rates as well as multiple signals can be streamed at the same time to the signal source. Dedicated Ethernet connections via the dual Gbit Ethernet port make it possible to stream up to 225 MB/s.
It is easily possible to synchronize multiple IZT S1000 GNSS units in a phase-coherent way. One of the IZT S1000 GNSS will take the role of the Master and the other IZT S1000 GNSS will be a Slave unit. This enables the possibility to generate multistandard constellations at the same time.
The IZT S1000 GNSS Realtime Simulator addresses a wide range of different customer applications. The customer benefits from its compact 2U form factor chassis. The chassis contains all digital processing hardware, synthesizers, and RF sections. As a versatile and comprehensive testing platform, it is offered a broad choice of available hardware options. For a specific customer application, a single device or extensive setup can be equipped with the exact hardware required.
