Location

In the Location Services menu, you can select the Global Navigation Satellite System ( GNSS ) types used for determining the device's position. Additionally, you can configure the multicasting of position data. The following sections explain how to perform these configurations. How this is configured, is explained in this section.


Summary

The Summary section of this page contains five switches for controlling different services:

  • Positioning Services (GNSS)
    Use this switch to     enable or disable the location services.
  • GLONASS Service
    This option allows you to enable the use of the     GLONASS (Russian) satellite system to calculate the device's location.
  • BeiDou Service
    This option enables the     BeiDou (Chinese) satellite system for calculating the device's position.
  • Galileo Service
    This option allows you to use the     Galileo (European) satellite system to determine the device's location.
  • Multicasting for Location Data
    Use this switch to     enable or disable the transmission of the device's current position on the Ethernet network via multicasting. The procedure for setting the device to multicast mode will be explained in the next module.
⚠ NOTE:
The GNSS receiver in this device can process data from two navigation systems simultaneously. Since the GPS system is always active when GNSS is enabled, it is recommended to enable only one additional system at a time.


Multicasting Preferences

In the Multicasting Preferences section, you can configure multicast settings on which the GNSS data will be casted. If the "Multicasting for Location Data" switch is enabled, additional options will become available under Multicasting Preferences, which lets you navigate to the settings by clicking on the right pointing chevron.


General Preferences

The General Preferences section allows you to configure settings for the multicast IP address and port.

Multicast IP Address

Ensure the IP address is within the range reserved for multicasting ( 224.0.0.0/4 ), as specified in RFC5771

  • default = 239.255.46.9
Multicast Port

There are no strict specifications for the port used for multicasting. You can select any port as per your requirements.

  • default = 31514
Downsampling of NMEA Data Sets

By default, NMEA data sets are calculated and transmitted once per second. You can adjust the Downsampling setting to limit the transmission interval. A value of `0` means "as provided by the GNSS receiver" , which is in this case once per second.

  • Default: 0
  • Unit: seconds
  • Range: 0 - 65.535


After configuring the multicast settings, click the Apply button to save and apply the settings to the device.
