Desite shares an upgrade update with you. Skydel software version 24.9.0 has been officially released,This update not only brings five new features, but also comprehensively upgrades performance optimization, user experience, and remote API, providing users with a more efficient and accurate simulation experience.

1、 Skydel 24.9.0 Key Features

1Multipath propagation in rural, suburban, and urban areasmodelThe environment has been integrated into the GUI

Users can directly choose the corresponding propagation model to simulate different multipath environments and propagation modes. The parameters that users can set are:

• Open Sky Limit:Minimum value: 0 Maximum value: 90, used to define the degree of separation between open sky and multipath areas

• Obstacle Limit:Minimum value: 0 Maximum value: 90, used to define the degree of boundary between obstacles and multipath areas, theoretically should be less than the value of Open Sky Limit

• NLOS Probability:Minimum value: 0 Maximum value: 1 If the satellite transmission path is located in an obstacle area, the probability of losing sight.

• Random Seed:Minimum value: 0 Maximum value: 4.29497e+09, random seed value, affecting the distribution formula within this propagation model

2Number of echoes for each signal on each satelliteIncrease from 4 to 5

3You can use the default low-pass filterconductBasic signal filtering

4Can be found on vehicle pages with fixed and circular trajectoriesDisplayed and improved ECEF position

5Add S band simulation

2、 New features in Skydel 24.9.0 version

• Can generate new Galileo E1 signals with intermodulation terms

• You can use the default low-pass filter for basic signal filtering

• Clock calibration can be configured for custom signals

• Can use configuration mode

• Increase the number of echoes for each signal on each satellite from 4 to 5

• The multipath propagation models for rural, suburban, and urban environments have been integrated into the GUI

• The 'Leave feedback' option is now available in the help menu

• The help menu now provides a link to upgrade Skydel

3、 Skydel feature improvement

• When importing GLONASS RINEX files, the valid simulation start time range will now be displayed

• The default OSNMA Merkle Tree start date is now set to the start of the Galileo subframe

• When adding custom signals, more information about ID format is now provided

• Increase the maximum number of echoes per signal on each satellite from 4 to 5

• Now displaying and improving ECEF position on vehicle pages with fixed and circular trajectories

• The center frequency of the S-band is now calibrated on X300 and N310

• Now you can configure the RSF field of NavIC

4、 Skydel feature changes

• Increase the maximum supported value of Galileo eccentricity to 0.5

• Update M-Code interface to version 10

• Added default power for QZSS custom signals

• GPU benchmark testing now uses the ExecuteGpuBenchmark command

5、 Skydel feature repair

• Corrected QZSS L1CB subcarrier

• Do not close Skydel again when canceling save and exiting

• If the IQ file path stored in the configuration does not exist, the invalid path dialog box will no longer be displayed

• When sending the SetModulationTarget command with DTA output type, if the output type is not DTA, the crash issue has been fixed

• Improved UI performance when selecting XONA XL in idle mode

• The Merkle Tree root field in OSNMA settings can now be copied at runtime

• Runtime commands in Wavefront mode are no longer sent to disabled nodes

• Fixed the crash issue when removing multipath during the simulation process

• Even with the Y-Code library set up, P-Code signals can now be simulated

• Fixed the updated OSNMA COP value of ephemeris

• The simulation will only start after all plugins have been initialized

• Corrected timestamp in IQ XML file

• Basic interference now has the same intermediate frequency limitation as advanced interference

• The intermediate frequency limit for advanced interference has been increased to 6 GHz

• Fixed the parity check vector of Galileo INAV in word types 17 to 20

• Now broadcasting reduced clock and ephemeris data for Galileo INAV based on word type 16 transmission time

6、 Remote API version 46

1Added command

-[Set/Get]CurrentPropagationModel：Set/retrieve the current propagation model

2. Remove command

-[Set/Get]MessageModificationToGpsMNav

-Navigation message family key "GPs_MNAV"

-Encrypt signal type enumeration value 'M-CODE'

3. Added Structure

-SignalWithComponent：A signal with optional components.

-Propagation Model Type enumeration:The types of multipath propagation models can be "Rural," "Suburban," "Urban," or "Manual.

4. Change

- SetModulationTarget：The 'WF' type is no longer supported (deprecated in v20.2).

5. Repair

-GetMultipathForID：Now return the same signal key as other commands.

-GetEnabledSignalsForSV：Now return the same signal key as other commands.

-ChangeModulationTargetSignals：When the minimum and maximum values of the sampling rate do not form a valid combination, an error is now returned.
