Users in the surveying community, among others, are benefiting from Galileo accuracy in the latest GNSS receivers from Javad, which are able to track all available Galileo signals. Thanks to the increased resistance to multipath and advanced signal design, Galileo capability makes the receivers particularly suitable for work in challenging environments.
Javad receivers have been Galileo-enabled since 2008, when the company’s receivers first tracked the Galileo E1/E5A signals. Since then, the receivers’ capabilities have expanded to add the Galileo E1/E5A, E5B/AltBoc and finally the E6 signals. The company’s 874-channel TRIUMPH 3 receiver, with new application-specific integrated circuit (ASIC), benefits from the full range of Galileo signals, as does its TRIUMPH-LS Plus receiver.?
Leveraging Galileo to benefit users
The receivers use all Galileo signals in a multi-system, multi-frequency RTK solution with four “super engines”. Each engine uses all signals from all satellites but with different parameters for different conditions. Galileo E5 AltBOC signals show the greatest multipath reduction compared to other signals and, when combined with Javad's multipath reduction (MPR) technique, this makes for an optimal solution.
“Ensuring that end users have the optimal service is our ultimate goal. This is why it is gratifying to see companies leveraging Galileo differentiators, such as reduced resistance to multipath, and combining these with their own techniques to deliver optimal service to their customers,” said Eduard Escalona, GSA Geomatics Market Development Innovation Officer.
Javad receivers also efficiently process Galileo signals for a fast and reliable Real Time Postprocessed Kinematics (RTPK) solution. RTPK is a recent innovation at Javad GNSS and combines the strengths of RTK and PPK into a system that can post-process RTK data and verify its results in parallel and in real time.
In addition, Javad GNSS receivers benefit from the low level of orbit and clock errors of Galileo signals. As a result, there are minimal jumps in computed autonomous position, even under conditions with poor position dilution of precision (PDOP). The JAVAD GNSS receivers are also designed to work with the Galileo High Accuracy Service (HAS) and support will be announced after the final specifications of the HAS have been published.
