Rohde & Schwarz recently demonstrated an ERA-GLONASS test setup consisting of the R&S CMW500 wideband radio communication tester and R&S SMBV100A vector signal generator as a GNSS simulator. This setup allows manufacturers and suppliers of automatic in-vehicle systems (IVS) to perform reliable and reproducible preconformance tests on their ERA GLONASS modules in the lab.
In the Russian Federation, ERAGLONASS works much like the EU’s eCall system. When an accident occurs, the IVS connects with a public safety answering point (PSAP) via the local wireless communications network and transmits a standardized minimum set of data (MSD). In addition to GLONASS or GPS coordinates, the MSD also contains additional data with information about the accident vehicle as specified in ERA GLONASS. Rohde & Schwarz developed its R&S CMW-KA095 application software to meet ERA GLONASS requirements in line with Russia’s GOST specification.
Based on the R&S CMW-KA094 eCall software, the R&S CMW-KA095 simulates a PSAP and controls the R&S CMW500 emulating a wireless communications network in the lab. The software also controls the GNSS simulator that supplies the coordinates required for vehicle localization. www.press.rohde-schwarz.com
Saneamento Basico do Estado de São Paulo (SABESP), a Brazilian water and sewage collection utility owned by São Paulo state and Latin America’s largest water company by market capitalization, has selected Spectra Precision ProMark 120 and 220 GNSS receivers to assist in gathering the geographic location of all SABESP network assets and the location of all customers.
To help improve revenue generation and reduce water loss SABESP developed two projects: LigGeo, to geo-reference the water meter location of approximately 4.8 million SABESP customers; and CadGeo, to geo-reference and register the location of the SABESP water and sewage network infrastructure www.spectraprecision.com

GNSS Software by Credo-Dialogue
The Russian company Credo-Dialogue has released Credo GNSS 1.0, a GNSS processing software. It is designed for processing of satellite geodetic measurements in differential mode. In this mode, the simultaneous operation of two or more receivers forms the baseline. Also in the program, users can view images from web services such as Google Maps, Bing and Express Kosmosnimki.
Fugro has introduced its high accuracy G2+ service, designed to benefit offshore operators around the globe who require positioning and measurement accuracy at centimeter level. It is an enhancement of Fugro’s highly regarded G2 service (based on GPS and GLONASS) and utilizes highly advanced GNSS augmentation algorithms developed in-house. www.oedigital.com
Spirent Communications has announced additional capabilities for its ultrawideband GSS6425, which enable recording up to 150MHz bandwidth of GNSS signals. Users can now record up to three RF frequency bands at any one time with 10, 30 or 50 MHz bandwidth each1. Other enhancements include ability to record up to four video streams, USB 3.0 support and easy remote control using tablet or smartphone.
A single portable test system, the ultrawideband GSS6425 allows customers to record GPS L1 and L2 and GLONASS L1 and L2 signals commonly needed for applications requiring very high accuracy such as surveying, precision agriculture, automotive research, and advanced navigation. www.spirent.com
KCS BV has extended their successful TraceMe product line with an intelligent location based positioning solution for indoor and anti-theft applications. The solution is based on RF with an intelligent algorithm of measuring the propagation time of transmitted (proprietary protocol) signals.
‘Listen before talk’ algorithm makes it practically impossible to locate the module which secures the valuable vehicle or asset. Supporting GPRS/ SMS and optional 3G, Wifi, Bluetooth LE, ANT/ANT+ and iBeacon provides easy integration with existing wireless networks and mobile apps. www.trace.me
The Z+F IMAGER® 5010X – a new 3D laser scanner by Zoller + Fröhlich, comes with a unique navigation system which works outdoors and indoors too! It will estimate the scanner position and orientation without any external targets in order to enable automatic registration. It also tracks the movements while carrying the device on to the next scanning position. Combining the Z+F IMAGER® 5010X with the newly presented software Z+F LaserControl® Scout, results in a totally new laser scanning workflow, called Blue Workflow, which allows you to register and check scans (completeness, etc.) already in the field – without using any targets.
During the preparation of playback scenarios for the upcoming leap second event this year, engineers at Racelogic identified a potential pitfall for GNSS engineers. The difficulty arises from the fact that BeiDou uses a different ‘day number’ for the date to apply the leap second compared with GPS and Galileo. GPS and Galileo use 1-7 as week day numbers, and BeiDou uses 0-6. If this fact has been missed during development, then the result is that the leap second may be implemented a day early on GNSS engines which are tracking the BeiDou constellation.
Indeed, four different Beidou enabled receivers, from four leading GNSS companies have been tested, and none of them appeared to handle the Beidou leap second correctly. This included an engine which originates from China!
Racelogic has since been in contact with two of these companies who have confirmed that their hardware does have a bug in the leap second code due to the numbering of the days. The error presents itself when the receiver is running on the BeiDou constellation alone, and when the date is the 29th of June this year. In some cases, the BeiDou leap second will be adjusted from 2s to 3s from midnight on the 29th June, which should in fact occur on midnight of the 30th. This will result in an error for the reported UTC time of 1s for the period of this day. In other cases, the leap second was not implemented at all when running on Beidou alone.
In order to help companies test for this problem, simulated RF data have been generated for the 29th and 30th of June, starting 15 minutes before midnight. Racelogic has two sets of files, one set contains Bediou only signals and the other contains a combination of BeiDou and GPS signals. Note that on some of the receivers that have been tested, when GPS is being tracked as well, the GPS leap second message overrides the one coming from Beidou and applies the leap second correctly. These scenarios are compatible with the LabSat3 triple constellation simulator, which is available on a free 15 day loan or can be purchased from Racelogic. www.labsat.co.uk
