4.4 Calculation Configuration
There are several calculation configuration options which can be changed by the use of commands. These
conf iguration options can update the way in which VERIPOS service types are utilised.
4.4.1 PPP Mode Selection via Terminal
The two PPP solutions that VERIPOS offer, Ultra and Apex, allow for decimetre accuracy positioning. Each of
these services have no range limitations and can be used in any location.
Some VERIPOS service codes include both the Apex and Ultra solutions. The LD8 can only compute one
solution at a time, which can be specified by using the
PPPSOURCE
command. Where only one of the PPP
services is enabled it is still required to match the selection to the activated service.
Users should ensure that the solution selected matches the service requested f rom the Helpdesk. When
changing the receiver PPP selection this will restart the PPP calculation. Allow time for this to settle before the
PPP solution becomes available.

4.4.2 SBAS Configuration via WebUI
