SatGen now with Galileo

Posted in News

SatGen screenshot 400The latest update to our SatGen GNSS simulation software for PC now incorporates Galileo RF simulation.

Designed to create a GNSS RF I&Q or IF data file based on a user-generated trajectory file, the updated software can now accurately simulate the European Galileo GNSS satellite constellation alongside existing GPS, GLONASS and BeiDou RF signal generation.

The full range of Galileo frequencies that SatGen can simulate are Galileo E1 B/C, E5a, E5b and E6 B/C (see table below for further information).

Mark Sampson, LabSat Product Manager - “Given the vast improvements in navigation and timing that Galileo has brought to its global users, we are extremely excited to be releasing a version of SatGen that allows engineers to generate Galileo-specific scenarios for their test procedures.”

Other changes to the software include various UI tweaks, performance optimisation and fixes. SatGen users can download the software update here.

SatGen 3.11.39 Galileo simulated RF frequencies

 GALILEO E1 B/C Transmitted by all Galileo satellites on the E1 (1575.42 MHz) frequency, same as GPS L1. Standard precision Open Service signal consisting of Data component B and Pilot component C.
 GALILEO E5a Transmitted by all Galileo satellites on the E5a (1176.45 MHz) frequency, same as GPS L5. Open Service signal consisting of Data component I with the F/NAV navigation message and Pilot component Q. Intended to be used together with E1 B/C to improve accuracy.
 GALILEO E5b Transmitted by all Galileo satellites on the E5b (1207.14 MHz) frequency, same as BeiDou B2. Open Service signal consisting of Data component I with the I/NAV navigation message and Pilot component Q. Intended to be used together with E1 B/C to improve accuracy.
 GALILEO E6 B/C Transmitted by all Galileo satellites on the E6 (1278.75 MHz) frequency. High accuracy Commercial Service signal consisting of Data component B and Pilot component C. Since the content of the C/NAV navigation message is encrypted, SatGen transmits a dummy navigation message, which should be accepted by all receivers.

LabSat recorded event files from Galileo Outage

Posted in News

Following the recent week-long outage of Europe's GNSS constellation, Galileo, LabSat are able to offer three one hour long files recorded during the period for test purposes.

The event on July 11 at 01.00 hrs UTC, a result of a 'technical incident' within the ground-based infrastructure caused a temporary interruption to the globally available Galileo navigation and timing service with the exception of Galileo's SAR (Search & Rescue) offering. Normal services were largely restored on Tuesday 16th July at 19.00 hrs UTC.

The files are freely available for download via the links below and are suitable for replay through a LabSat 3 (.ls3 format). LabSat 3 Wideband users will need to convert the files accordingly.

The full data set is available from on Wednesday 10th July at 14.20 hrs UTC to Tuesday 16th July at 19.07 hrs (UTC). This data set of 143 files in one-hour recorded files is about 4.2 TB of data and can only be transferred on a SSD. This will be a chargeable item for the media used. Please contact for further details.

New version of SatGen v3

Posted in News

An updated version of SatGen v3 is now available to download. Along with a number of optimisations and fixes, this is a major update to the capabilities of the software as it now allows for the simulation of new satellite signals such as L2, L2C, and L5 – making the use of SatGen with the LabSat 3 Wideband significantly more powerful.

This latest version also allows for the creation of complex (multi-frequency, multi-constellation) scenarios, enabling development and test of dual frequency GNSS receivers in a highly dependable and repeatable manner.

With L2C likely to be fully operational within the next two to three years once twenty-four satellites are transmitting the signal (currently at nineteen), the emergence of dual frequency devices is set to rapidly accelerate. Taking advantage of the robust simulation capacity of LabSat 3 Wideband hardware in conjunction with SatGen V3 software will give a competitive edge to those manufacturers leading the way in dual frequency design.

SatGen can now be used to create a single scenario containing all the upper and lower L Band signals for GPS, GLONASS, and BeiDou, and will take advantage of the LabSat 3 Wideband’s ability to read RF data at up to 80 MB/s.

The new software can be found here, and release notes here.

Next leap second adjustment coming soon

Posted in News

Another leap second is about to be added to official timekeeping on December 31, 2016. This occurs approximately every eighteen months, to compensate for the very gradual slowing of the Earth’s rotation - and whilst it makes everyone's day and year officially one second longer, it is a change that is hardly significant unless you are an engineer or product designer dealing with GNSS devices.

Do you know how your GPS device's firmware and algorithms will behave during the upcoming leap second correction? Are you prepared for the 2016 leap second adjustment? Many have been caught out before, but it is easy to avoid...

With LabSat you can simulate leap second corrections, including the one on 31st December 2016 at your desk. RACELOGIC have provided the relevant scenarios to download for free.

Download the LabSat 3 leap second scenarios that simulate the last and upcoming leap second event now.

If you have purchased SatGen software, you can also simulate previous leap second events to test the robustness of your device. The latest SatGen v3 software release offers leap second events between 30th July 1981 and 31st December 2016.

For the first time ever we are exhibiting at the 7th China Satellite Navigation Conference (CSNC) in Changsha, China on 18-20 May. Daniel Unander, LabSat Product Manager for our Asia Pacific Office is teaming up with Guangzhou Zeer Testing Technology, our appointed LabSat distributor for China for the event.

CSNC is the largest GNSS fair of its type in China attracting over 2000 experts in the field and is supported by 11 national authorities.

Come and visit us at Booth T-1 where you can see a preview of our upcoming LabSat Wideband product along with our LabSat Real-Time demonstration.

LabSat 3 Turntable System: A full navigation testing solution

Posted in News

To cover for losses in satellite visibility most OEM navigation systems have a dead reckoning capability. This utilises vehicle wheel speed data and rate of turn information to provide the system with a guide to the vehicle's current location when GPS signals are not available.  

When it comes to testing these systems on the bench however, if the dead reckoning signals are not present the navigation unit will not function correctly. 

To overcome these obstructions we have developed a full navigation testing solution. Watch the video below to see how it works. 

SatGen Version 3 now includes BeiDou signals

Posted in News

SatGen v3From LabSat, the most cost effective GNSS simulator available, comes SatGen V3.

SatGen is a powerful and intuitive software package that gives you the ability to create GNSS scenarios for replay through any LabSat simulator – and now it includes BeiDou!

The software creates either user generated or imported trajectory files for use with a LabSat. The addition of the BeiDou B1 signals means that you can now test your device’s effectiveness as if it were being used within the operating area of the Chinese constellation – which at present only provides full coverage in Asia.

The BeiDou constellation is set to become globally operational by 2020. With the new SatGen you can create scenarios that include signals from satellites yet to be launched, so that you can develop new products in readiness for the full constellation.

SatGen V3 can produce scenarios with one, two, or three sets of signals being simultaneously output: GPS, GLONASS, and now BeiDou. If you have a triple constellation LabSat 3 the software now matches the record and replay abilities of your hardware.

If you’ve never used SatGen before, why not try it out? Our free to use demo version is available from here.

To purchase a full copy please contact your LabSat distributor.
