    Racelogic Ltd. has released the latest update to its SatGen GNSS simulation software for PC, which 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 below for details).

    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. Because the content of the C/NAV navigation message is encrypted, SatGen transmits a dummy navigation message, which should be accepted by all receivers.

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

    Other changes to the software include various user interface tweaks, performance optimization and fixes.

    Racelogic updates Labsat’s SatGen software to simulate L2C and L5

    Racelogic has announced a major update to its SatGen simulation software for use with the LabSat 3 Wideband simulator.

    The software now includes simulation of the L2C and L5 GPS signals, meaning that SatGen V3 can be used to create one scenario containing all 13 signals from GPS, GLONASS and BeiDou constellations, the company said.

    The simulation accuracy has also been improved — for example, most of the GPS pseudorange residuals are now sub-meter.

    Signals that can be simulated simultaneously with SatGen V3 Wideband include:

    • GPS:​ L1, L1P, L2C, L2P, L5I, L5Q, L1M, L2M (noise only)
    • GLONASS: L1 OF, L2 OF
    • BeiDou: B1I, B1-2I, B2I

    SatGen software allows users to create a GNSS RF I&Q or IF data file that can be replayed on a LabSat, which is based on a user-generated trajectory file. This allows simulators of almost any kind of test, at a set time and date, anywhere in the world.

    SatGen complements the LabSat range of GNSS simulators, and is available in single, dual, triple and multi-frequency/multi-constellation versions.

    LabSat showcased the upgrade at the ION GNSS+ conference, which took place Sept. 24-28 in Miami.

  • LabSat’s SatGen v3 Adds BeiDou to Simulator Scenarios

    Photo: LabstatSatGen v3 software is now available for the LabSat GNSS simulator by Racelogic. Version 3 includes BeiDou (BDS) in addition to GPS and GLONASS.

    SatGen is billed as a powerful and intuitive software package that gives users the ability to create scenarios for replay through any LabSat simulator. The software creates either user-generated or imported trajectory files for use with a LabSat simulator.

    The addition of the BeiDou B1 signals means that users can now test a 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 v3, users can create scenarios that include signals from satellites yet to be launched, so new products can be developed 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. The software now matches the record and replay abilities of the LabSat 3 simulator.

    A trial of SatGen is available here. To purchase a full copy contact a LabSat distributor.
