Time Synchronous Signals with Multiple R&S SMBV100A Vector Signal Generators
This application note explains how to synchronize the signals from multiple R&SSMBV100A vector signal generators in time. The synchronization of the instruments is based on a master-slave principle where one R&SSMBV100A acts as master and supplies all necessary synchronization signals to the other instruments (slaves). The setup is simple and provides highly synchronized test signals.

Spectracom: Leap Second Testing Made Easy
The first leap second since late 2008 will be added to the official time scale on June 30, 2012. This will be the first mid-year leap second event in 16 years. No doubt most GPS receivers in current production have not experienced a leap second event and none would have experienced a midyear leap second. For these reasons, it is strongly recommended to test the upcoming leap second event for all GPS receivers and systems to determine if algorithms and software successfully manages the leap second event and to uncover any detrimental effect of the leap second discontinuity.

NovAtel: Ultra-Precise Positioning for Sport Applications
The University of Calgary Schulich School of Engineering, through its PLAN Group has developed and tested, in collaboration with Own The Podium/À Nous le Podium 2010 and Alpine Canada Alpin, an ultra-precise, ultra-light and autonomous sensor, namely STEALTH, the Sensor for the Training of Elite Athletes, to support the Canadian Alpine Ski Team during training. The GPS-GLONASS based sensor has proven to operate very well under a variety of conditions and is now used routinely by the ski team. Authors: Gérard Lachapelle, Aiden Morrison and Richard Ong

Orientation Performance Test of Xsens MTi-G AHRS for Automotive Applications
Orientation performance of the MTi-G, a lowcost miniature MEMS Attitude and Heading Reference System (AHRS), was tested in a car on a test track. Two tests were performed: a high-speed test on an oval banked track and a high-dynamic maneuvering test on a track with many corners.

PCTEL: The Changing Global Security Environment
Military missions in the new hybrid environment of traditional and irregular warfare often require the mobility that wireless technology can provide. Both electronics and antennas are typically enclosed in small, ruggedized packages where harsh environmental conditions require protection from dust, chemicals, humidity, and extreme, fast changing temperatures. This application note discusses the need for specialized GPS and wireless communications antennas providing connectivity with satellites, aerials, or land-based communications infrastructure.
