Skydel SDX Release 17.1 adds a fine level of control on signal multipath to the software-defined GNSS simulator. SDX 17.1 introduces a powerful multipath simulation option, enabling users to create less-than-ideal signal propagation conditions for GNSS testing. Multipath echoes can be added and fined-tuned for each satellite, per signal. Control is possible via four fundamental attributes: pseudorange offset, power loss, Doppler shift and carrier-phase offset. It’s now convenient to create simplified test conditions otherwise impossible to achieve with the live sky. The new options are fully controllable through the SDX application program interface (API), and can be modified on the fly while the simulation is running.Release 17.1 also adds L2C navigation message modification. Besides the usual conditions such as start and stop time and PRN number, users can specify the message type, and the message content to match. Because the CNAV message is 300 bits long and not subdivided in words like the NAV message, managing the modifications as a per-bit fashion would be tedious. The interface solves this by letting you add modifications for portions of the message — and lets users add as many as they need. Software-defined radios (SDR) can take a few seconds to initialize when starting the simulation. To improve software synchronization performance, Skydel has added an armed state. Upon clicking the arm button (or issuing the command through the API), the armed state prepares all hardware. When the start command is later received, the delay to emit the GNSS signals is minimal. Other updates have also been made. See the release notes for the full list. As always, existing licensees benefit from an immediate upgrade. Among the next items on SDX’s development agenda is the release of advanced jamming capabilities through an innovative integration with the GNSS simulator.
