V6.07 key release information

Important notice: Windows 7 is no longer supported. What this means for your system:

Further to the announcements made in 2018 (NWS10171) and 2019 (NWS10196), support for Windows 7 by Spirent's positioning and navigation products has now ended. Consult NWS10242 for the latest information and details on what to do if you are affected.

Version v6.07 is the final PosApp release Spirent built for use with Windows 7. Subsequent releases will not be tested or qualified for use with the retired operating system. All new simulator purchases are shipped with Windows 10.

Visit FAQ19022 for a list of the first Windows 10 compatible software versions, and the last release tested with Windows 7 for the following positioning products:

PosAppTM (SimGENTM, SimREPLAYplusTM, SimTESTTM and SimSCUTM), SimCLASSTM, SimSAASTM, SimMCODETM, SimREMOTETM, SimSAFETM, Sim3DTM, SimAUTOTM, SimCHANTM, SimINERTIALTM and SimSENSORTM

New ICD documents supported in V6.07 software release:

IS-QZSS-L6 Nov. 2018 version
BDS-SIS-ICD-B3I V3.0 Feb. 2019 (for the change notes, please refer to article NWS10240 on Spirent Customer Service Center)
BDGIM Ionospheric Model for BeiDou Phase 3 signals
ISRO-IRNSS-ICD-MSG-INCOIS-1.0 Mar. 2019 version

New features:

GALILEO E5 RINEX observation data can be output separately as E5a and E5b

Added in V6.07 release, GALILEO E5 observation data can now be output separately as E5a/E5b in a RINEX output file, rather than as 1 signal. This feature will help customers in, for example, RTK simulation tests where GALILEO E1 and E5a signals are used together.

Log zero values in sat_data_v1a1.csv Bulk Logging file for out-of-sight satellites

V6.07 release introduces the capability to exclude or include logged data for all satellites, even when they are not simulated. The number of channels displayed is only limited by the simulator’s specification and the number of channels purchased. This figure is represented by the value in cell “D2” of the sat_data file.

With satellite data logging enabled in the Bulk Logging options, select “log all satellite channels” to populate the sat_data_*.csv file with the full number of channels the system is configured to produce. "0" values are displayed for satellites that are out of view of the receiving antenna.

States:

  • Disabled (Default) – exclude zero values in satellite data logging file



  • Enabled – include zero values in satellite data logging file. Zero values highlighted in yellow

New dedicated location for SimTEST scenarios.

As of V6.07 release, SimTEST has its own dedicated scenario folder - in alignment with SimGEN and SimREPLAYplus. The new default location of the example SimTEST scenario (simtest_default.scn_replay) and shared sources files is shown below:

  • GSS7000
    • D:\posapp\Scenarios for SimTEST
  • GSS6300M and GSS6300M-I
    • Windows, 64-bit operating system
      • C:\Program Files (x86)\Spirent Communications\Positioning Application\Scenarios for SimTEST
    • Windows, 32-bit operating system
      • C:\Program Files\Spirent Communications\Positioning Application\Scenarios for SimTEST

This change is in response to customer feedback and is intended to make locating the example SimTEST scenarios easier.

If you have an idea that could improvement our software, please bring it to our attention by contacting Spirent Global Services via support@spirent.com, or by raising a Service Request from the “Cases” tab on the Customer Service Centre (CSC) website: https://support.spirent.com.  

Simulate NavIC (IRNSS) AutoNav feature with Spirent Software

AutoNav is a feature of IRNSS / NavIC constellation that allows satellites to transmit differential correction (DC) data within message type 14 to other satellites in the constellation. This DC data provides corrections that can be applied to both clock and ephemeris data before the satellite broadcasts its own NavData.

PosApp simulates this by allowing the user to set a satellite to AutoNav mode at a custom time during the scenario run in the “Status control” menu. When this point is reached in the scenario, the satellite will enter AutoNav mode and will begin to transmit the DC parameters set in the “Diff. correction table” menu.

SimROUTE now supports China and Korea region

Spirent PT’s SimROUTE is an online tool that generates route-matched trajectory data from online map services. It can rapidly create road-matched trajectory data - for any route definable on the map - to be used as vehicle trajectory when testing GNSS performance with a Spirent RF simulator.

With the integration of Open Street Maps, SimROUTE is now available to customers in China and Korea who have limited access to the Google Maps server.

SimROUTE is available free of charge to Spirent customers with a valid Spirent Support Service contract. It is accessible whenever you need, simply by signing into the Spirent Customer Service Center and clicking on the left-side toolbar Applications link.

  1. Click on the SimROUTE image link:



  2. SimROUTE V3.02 will be displayed - with a revised menu bar
  3. Click on ‘Switch to SimROUTE with Open Street Maps’ (highlighted in yellow)

 



The SimROUTE with Open Streetmaps - labelled as SimROUTE ORS - application is displayed. Simply define a start and end location, and a .umt file containing route information will be generated. This file can then be used as trajectory file with a Spirent simulator.
