Rohde & Schwarz Offers Fast Production Testing for GNSS Receivers

August 11, 2015By
The R&S SMBV100A vector signal generator equipped with the SMBV-P101 package.

Rohde & Schwarz now offers a new, speed-optimized production tester — the R&S SMBV100A vector signal generator equipped with the R&S SMBV-P101 package. During production testing of modules and receivers for satellite-based communications, the basic GNSS signal reception and the connection between the antenna and GNSS chipset need to be checked. The GNSS production tester simulates separate satellites for the GPS, GLONASS,... read more

Successful Testing — and Why It Is More Important Than Ever

March 2, 2015By

By John Pottle and Neal Fedora Precision matters. While “accuracy” is somewhat one-dimensional, “precision” is multi-faceted. We submit to you that whatever area of GNSS-based location you are interested in, precision matters today and will matter more in the future. In this column, we’ll explain why this is. Traditional test approaches involve taking measurements to evaluate fundamental performance, for example,... read more

Spectracom Begins Program for Application-Specific Testing

March 6, 2014By
Spectracom’s GSG-6 Simulator with monitor.

Spectracom has begun a program to develop robust application-specific testing solutions. The program fills what the company calls a technology and expertise gap in providing customers in a variety of industries the tools to perform more comprehensive qualification of their mission-critical systems. Examples of these industries include: multi-constellation (GPS, GLONASS, Galileo, BeiDou) simulation; integrated MEMs/INS testing; interference detection and mitigation... read more

GNSS Receiver Evaluation

January 1, 2009By
FIGURE 1. Traditional in-vehicle receiver testing.

This article addresses how best to quantify “which navigation system performs best” in a realistic testing scenario. The methodology focuses on land vehicles navigating in urban environments, but applies equally well to pedestrian navigation and can be adapted for testing assisted-GNSS implementations. During a drive test, the truth-reference system and RF recording system log samples to disk, with no need for the receivers under test to be included during the actual drive. read more
