This webinar covers the technological background of the different positioning methods supported in LTE in addition to Assisted GPS (A-GPS). This includes observed time difference of arrival (OTDOA) based methods such as PRS as well as enhanced cell ID based positioning.
A GPS L1-frequency signal is recorded using a receiver such as an R&S®TSMW or an R&S®FSV. Then the I/Q data is stored via the digital I/Q interface on an R&S®IQR device. Playback is realized using an R&S®SMBV signal generator that is also connected to an R&S®IQR via a digital I/Q interface.
The R&S®SMBV100A supports receiver testing under realistic conditions by offering features such as obscuration simulation and automatic multipath generation. Out of a multitude of possible test scenarios – with predefined or user-specific settings – this application note presents some examples to give an impression of the instrument’s capabilities.
Testing global navigation satellite system (GNSS) receivers can be done easily, reliably and cost-efficiently by using the R&S®SMBV100A vector signal generator. This GNSS simulator can generate GPS, Glonass and Galileo signals for up to 24 satellites in real time. This application note explains how to perform automated receiver tests using the R&S®SMBV100A.
Location Based Services (LBS) involves the process of determining where a device is located. Global Navigation Satellite System (GNSS) based solutions are highly accurate and the technology of choice for absolute position accuracy, providing the device has a good line-of-sight, but this is not always the case. A device can be in a highly dense… Read more »
