    Select Velocity Profile ON to use a velocity profile. After selecting Velocity Profile ON you must also select a Profile Data File, see section 5.2.2.2. This option is only available when the GSS6100 is running. The velocity profile superimposes a cyclic sequence of changes to the selected Pseudo Range Velocity.
  • Page 33 During the jerk period (which is a period of linearly increasing/decreasing acceleration) the velocity changes non- linearly. The GSS6100 fully models these effects. Reference f) documents the profile. It comprises the following sequence: Constant Initial Velocity Period (D)

  • Page 39 Note: The data message is buffered in hardware. Changing the parity status while the GSS6100is running results in a delay before the change is reflected in the RF output. Spirent recommend you set-up this feature while SimCHAN is idle and the GSS6100 is not operating. GSS6100 and SimCHAN user manual 5-13 ©...
  • Page 40 For either GPS or SBAS, a Message File Template number in the range 0 to 3 identifies the appropriate Template. The Message File Template number shown will be the active selection for the GSS6100, it is used to generate the Navigation/Correction message component of the RF signal.

  • Page 41: Table 5-5 Prn Assignments

    [Remote Command: COSW see section 6.2.5] Disable PRN code generation by de-selecting PRN Code On. The GSS6100 is capable of generating any one of the 1023 possible random sequences associated with the GPS C/A encoder. Each sequence or code is determined by the start conditions of the G1 and G2 encoders.
  • Page 42 5.2.8 Pseudo Range [Remote Command: IPRG see section 6.2.11] Note: Pseudo Range may only be set while the GSS6100 is idle. Pseudo Range simulates the distance between the receiver and the satellite at the start of the run. This ranging effect is produced by delaying the start of the PRN and data message signals to simulate the desired pseudo range.
  • Page 43 You can clear all messages by clicking Clear. Note: SimCHAN automatically removes old messages and it is not normally necessary to clear old messages. GSS6100 and SimCHAN user manual 5-17 © Spirent Communications Plc 2005 - 2007 GSS6100 operating details...
  • Page 44 The GPS Navigation Message carries date and time information that increments at the 6 second GPS Epoch rate. This is automatically inserted by the GSS6100 to match the operation time. The parity field is computed dynamically by the GSS6100, but data other than Epoch time remains fixed.
  • Page 45 Select the template type, either GPS or SBAS. Select a template from the Template File Available drop-down list. Use Template Slot ID to select the ID number of the GSS6100 flash memory location that will hold the template. There are four locations numbered 0 to 3.

  • Page 47 External Trigger cannot be utilised. If an external reference frequency signal is applied, there will be a period (after the GSS6100 starts running) when the RF signal is disturbed and out of specification. This state will continue until the GSS6100 locks to the reference signal.
  • Page 48 Figure 5-18 Hardware Options and Settings The Hardware Options and Settings dialog box, see Figure 5-18, displays the Serial Number of the connected GSS6100 unit and the Versions/Release numbers of the various Firmware elements loaded into the unit.
