Rohde and Schwarz International's R&S SMBV100A multipurpose vector signal generator has integrated a global navigation satellite system (GNSS) technology solution.

GNSS receivers are characterized by running a number of tests such as tests that measure how quickly a receiver can fix its position after it is switched on, how much power it needs to do so and how accurately the calculated position matches its actual position. In order to be able to make statistically sound statements about the characteristics of a receiver, users normally perform a complete series of tests under various scenarios.

The GNSS solution for the R&S SMBV100A will enable the satellite simulator to simulate a wide variety of scenarios. With only a few commands, the R&S SMBV100A will be able to use up to 12 satellites and generate complex scenarios with unlimited time. It is also possible to simulate stationary positions and scenarios that simulate the movement of a receiver along a chosen route. Users can also simulate restricted reception conditions on the satellites, such as driving through a tunnel.

The R&S SMBV100A GNSS solution offers customization options that allow users to change the configuration of the signal generator to keep pace with new test requirements. New features can be added on an as-needed basis. Additional functions, such as 12 instead of 6 satellites, can be activated with a license key and eliminates the downtime associated with hardware installations.

The R&S SMBV100A can support several satellite, mobile radio and wireless and radio standards simultaneously. With the new technology, manufacturers of mobile phone or car radio that have GNSS receivers need just one signal generator to check multiple functions all at once.

The GNSS software options for the R&S SMBV100A vector signal generator are now available from Rohde & Schwarz. These include the R&S SMBV-K44 option (six satellites for GPS), R&S SMBV-K66 (six satellites for Galileo), R&S SMBV-K65 (A-GPS), R&S SMBV-K91 (extension to 12 satellites) and R&S SMBV-K92 (additional functions such as moving scenarios or multipath propagation).
