    Throughout this manual, references are made to the VERIPOS Helpdesk. The Helpdesk is a service provided as first point of contact for all VERIPOS technical enquiries and fault reports. It is manned 24 hours per day, 365 days per year. Full contact details are listed in the Contact information section.

  • Page 4: Activating Veripos Correction Services

    1.5 Activating VERIPOS correction services VERIPOS correction signals are provided as a chargeable service. In order for the LD8 to decode corrections and output a corrected position, it must be activated. The user can send a request for an activation of services to the VERIPOS Helpdesk and the activation will then be sent via L-band satellite to the requested unit.

    Google Chrome is required to configure the LD8 for operation. Both Microsoft Edge and Internet Explorer come pre-loaded onto VERIPOS PCs when issued with the unit. The LD8 is shipped with a factory default IP address of 192.168.2.8. The connecting PC or laptop should be configured to use the same IP subnet.

  • Page 13: Configuration And Operation

    4 Configuration and operation There are two ways in which the LD8 can be configured, by using VERIPOS Quantum software, or by using the LD8 WebUI. Quantum must be used if being used for system monitoring. If Quantum is not available, system configuration must be performed through the WebUI, which features a terminal application that can be used for sending commands.

    FRESET USER_ACCOUNTS 4.3 L-band configuration Tracking of an L-band beam is required to receive VERIPOS service correction and activation data. This section will detail how to establish and confirm successful L-band tracking to make use of VERIPOS services. Auto Beam is the recommended way to manage L-band beam choices. When in this mode, the LD8 will track up to three beams simultaneously with tracking determined based on available L-band satellites and elevation.
  • Page 16 Verichart can be used to assess L-band availability by creating coverage charts specific to a work location. Where possible, different VERIPOS receiver units on the same vessel should be set to different beams to maximise redundancy. Selecting beam via WebUI To select Auto beam (or a single beam if required) navigate to Configuration >...
  • Page 17 A custom L-band beam name and frequency (in Hz) can be manually entered, however this should be used only under the instruction of VERIPOS support. The format for assigning a user L-band beam is as follows: ASSIGNLBANDBEAM MANUAL BEAMNAME FREQUENCY 1200...

    If in doubt as to the LD8 unit ID and/or the activation service code enter the following: LOG VERIPOSINFO The LD8 unit ID is required for VERIPOS to activate services and each activation/deactivation is unique to each unit ID. The activation service code can be used to determine what services the unit is activated to receive.

  • Page 19: Calculation Configuration

    The LD8 is capable of tracking and using correction data from Satellite Based Augmentation Systems (SBAS). If SBAS is enabled a SBAS DGNSS solution will be output in the event of VERIPOS solutions failure. To enable/disable SBAS navigate to Configuration > Positioning and click Receive (Rover), followed by Next.
