18. Location Service Settings in SmartPTT Radioserver Configurator

If you don't have any Subscriber Groups added in Radioserver Configurator, then GPS is available for all radios.

If you have Subscriber Groups added in Radioserver Configurator and Allow Dispatcher to Amend Location Update Time Interval is ticked, then Dispatcher will be able to change subscriber location update time interval. And Dispatcher will be able to get location information even if Groups are unselected.

Group2.png

 

If you have Subscriber Groups added in Radioserver Configuratorand Allow Dispatcher to Amend Location Update Time Interval is not ticked, then to get GPS coordinates from the specific Group of Subscribers, specify time interval to request location information and select ON to be able to get GPS from this group of radios.  If Group is not ticked, then Dispatcher won't be able to get information about location of the subscribers included to this Group

 

19. Show on Map

Make sure that on Dispatcher Console in Properties Window of Subscriber GPS Support  and Show on Map are ticked and Interval is specified (Interval should be bigger than Min. SU Location Update Interval, sec specified in Radioserver Configurator ).

Note! 

SmartPTT are using the following parameters in LRRP request:
RequestId, TimeStamp, Latitude, Longitude, Accuracy, Speed(Velocity)

Real experiments proves that window size should be 7, it does not work with less than 7.
We recommend Window Size = 8 because in case privacy is used in the radio system, you need to increase window size up to 8. So Window Size = 8 will work for any radio sysem. 

 

21. Enhanced GPS Update Interval (Repeater configuration only)

Location Update Intervals can be 30 seconds, 1 minute, 2 minutes, 4 minutes or 8 minute. Specify one of the listed location update intervals in Subscriber Properties Window.

22.  Accuracy Radius (starting from version SmartPTT 8.0)

If GPS information is recieved by Radioserver but Subcriber icon is not displayed on the map, make sure that recieved locations has less inaccuracy than value specified in Accuracy Radius (m) field.

23. Time Zone

Make sure Time Zone in Operating System is selected correctly for both Dispatcher and Radioserver. 

 

Radio sends locations even Show on Map is disabled.

1. ARS ID (in SmartPTT versions 7.4. and lower)

  It is necessary that Start (Selected Show on Map) and Stop (Unselected Show on Map) commands were sent from the same ARS ID.

So if you need to change ID of Slot or Control Station ID in Radioserver Configurator, then first send stop (Unselected Show on Map), then change ARS ID in Configurator and then select Show on Map again.
