The year 2017 will soon be coming to an end and looking back at the many improvements we’ve built into our GNSS simulator, we can safely say, “mission accomplished”. Yet there are still a few days remaining to roll out one final “17” release of SDX… so here it is!
So what’s in store for users of SDX 17.12?
Engineers working with GNSS-enabled technology are often obligated to implement a broad range of antenna patterns, from simple to complex ones. Examples that come to mind are when designing optimal antenna form factors, testing anti-jamming capabilities, or creating equipment for specific environmental applications.
With release 17.12, all SDX users benefit from a 3D upgrade to gain antenna patterns, as well as—new feature!—custom 3D phase offset antenna patterns. These new options replace the previous ones found in the vehicle’s antenna settings.
A 3D gain or offset antenna pattern is expressed with a graph displaying either the gain or the phase offset, through the 360 degrees azimuth and -90 to 90 degrees elevation, thus creating a full 3D sphere mapping around the antenna.
The CSV import-export options bring customization control over the 3D antenna patterns as well. CSV files are composed of a two-dimensional matrix of values; SDX interpolates between specified azimuth/elevation points thus covering the whole 3D space. The matrix can be of any size; SDX automatically detects the number of rows and columns while importing your data, thus offering convenient flexibility.
This enables quick and easy setups, while providing fine-grained control to users requiring large mappings that depict complex patterns.
One of the most powerful features of SDX is its synchronization capabilities. Along with the timing improvements that were part of the last release, we continue to further refine this feature set in this latest version of SDX. As a result, it is now possible to push a SDX scenario configuration from the master instance to all slave instances. This unique feature brings obvious workflow improvements to any simulation setup.
