Telit GNSS Module Enables High-Performance Position Reporting

April 15, 2015By

Telit Wireless Solutions has released a new GNSS module, the SE868-V3. The positioning module combines GPS, GLONASS, Beidou, Galileo and SBAS, which enables the creation of high-performance position reporting and navigation solutions. The SE868-V3 can navigate to -162 dBm and track to -166 dBm, providing improved performance in harsh environments. It is pin-to-pin compatible with the former SE868-V2 as well as the... read more

Honeywell’s Global Tracking solution has passed the final acceptance test for use on the European Space Agency’s (ESA) Galileo search and rescue program by demonstrating dramatically reduced emergency response times, Honeywell said. Honeywell Global Tracking, part of Honeywell’s Scanning and Mobility business, is working in partnership with the Aerospace & Defense division of Capgemini, the prime contractor for the Galileo... read more

Cobham Offers Aeroflex Tester for ADS-B

April 13, 2015By

Cobham AvComm, formerly the Aeroflex AvComm business unit, has introduced the ATC-5000NG NextGen ATC/DME Test Set. Designed for engineering development, design validation, manufacturing and return-to-service test applications, the ATC-5000NG is the replacement product for the legacy SDX-2000 and the ATC-1400A/S-1403DL. The software defined radio architecture supports more transponder RTCA DO-181E test capability than the legacy products did and has new capability... read more

Rohde & Schwarz Used to Test ERA-GLONASS Systems

April 13, 2015By

The Certification Center Svyaz-Certificate in Russia is now using the R&S CMW500 to certify ERA-GLONASS systems in line with the TR CU 018/2011 technical guideline. The independent Russian test lab is currently the only test lab in Russia accredited to certify these systems. The R&S CMW500 is a wideband radio communication tester. Equipped with the R&S CMW-KA095 application software, the... read more

Handling the Biases for Improved Triple-Frequency PPP Convergence
Precise point positioning (PPP) can be considered a viable tool in the kitbag of GPS positioning techniques. One precision aspect of PPP is its use of carrier-phase measurements rather than just pseudoranges. But there is a catch. Often many epochs of measurements are needed for a position solution to converge to a sufficiently high accuracy. In this month’s column, we look at how using measurements from three satellite frequencies rather than just two can help. read more

Xsens Adds Active Heading Stabilization to IMU

April 2, 2015By

In the latest update of its Motion Tracker product portfolio, Xsens has added active heading stabilization (AHS) to its core sensor fusion algorithms on the MTi 10-series and MTi 100-series. Both series are MEMS-based inertial measurement units (IMU), attitude and heading reference systems (AHRS), and vertical reference units (VRUs). The AHS algorithm delivers fundamentally improved heading tracking accuracy, Xsens said. The improved robustness in... read more
