SDX Release 16.11: Say Hello to BeiDou + New User Manual

It’s official: with the addition of the BeiDou navigation satellite system, SDX has now become a 4-constellation GNSS simulator. In this new release, the BeiDou B1 and B2 signals have been added to the array of satellite signals that SDX users can use in their simulation scenarios.

GNSS simulation with 4 simultaneous constellations

Galileo Signal Update

That’s not all: we’re also adding to this release the Galileo signals E5a and E5b, complementing our support of the Galileo navigation system started in version 16.7.

Skydel now offers an impressive list of signals that covers the four global navigation satellite systems:

  • GPS: L1 C/A, L1P, L2P, L2C
  • GPS encrypted codes: Y & M (through Talen-X BroadSim)
  • GLONASS: G1, G2
  • Galileo: E1, E5
  • BeiDou: B1, B2

Picture this: with this update, it is now possible to create a GNSS simulation with a complete 4-constellation dual-frequency scenario, all on a single SDR using only COTS hardware. We expect this SDX setup will appeal to GNSS product engineers and designers, as well as research institutes that:

  • want a simulator using repurposable hardware for their lab;
  • already have a compatible SDR at their disposal;
  • are looking to develop a new GNSS-enabled product that requires a future-proof, scalable test solution.

On the other side of the spectrum, SDX can be set up (or upgraded!) with a powerful PC and dual SDR to simulate an even wider range of satellite signals. This powerful configuration can meet the toughest GNSS simulation requirements, for example, those needed for a RTK test environment.

Signal Selection Redux

To be rolled out with this release is an updated settings panel for the Output (formerly called “Modulation”). An important feature introduced with the new Output is the ability to add multiple radios, a powerful addition in release 16.11.

The new Output User Interface

Signal selection for each RF output of the radio is now a lot more intuitive! Moreover, since many users have a preferred SDR setup, there’s a “set as template” feature to get you up and running every time you start a new simulation configuration.

User’s Manual

SDX has a new user manual. Available from within the application, it covers recommended hardware configurations; provides guidance for software installation, network cards and GPU drivers; and goes over the use of the software in detail with clear explanations and screenshots.

As always, we’re really proud of this update. A lot of work went into it, and we sincerely hope these improvements help our users in their daily GNSS projects.


So, what’s next? In pure RERO fashion, we will continue to expand capabilities, add features, and improve the overall experience of SDX. Stay connected, as we’re already working on the next release, to which we plan to add both multipaths and advanced jamming capabilities with an unrivaled jamming to signal ratio.
