Ld6 Solutions - Veripos LD6 Operation Manual

2.9 LD6 Solutions

Depending on the services enabled by the VERIPOS service code (Access code),
the LD6 processor and software will simultaneously compute up to three different
position solutions.
Only ONE of these may be a PPP solution.
Where both Ultra and APEX are enabled by the service code, the user manually
selects which PPP solution to use.
Refer to section 2.10.4 in this manual for details on selecting the NMEA solution
strings under Home/ Solutions/ NMEA.
For most positioning applications users are recommended to select the Best
solution.
The three solutions have designated names:-
•
Std (Standard) – a Differential GPS (DGPS) solution using GPS satellites only
•
Std² (Standard²)– a DGNSS solution using both GPS and GLONASS satellites
(where available from the GNSS receiver card)
•
Best – The best (high accuracy) solution currently available
Best solution output and backups
Where a VERIPOS Precise Point Positioning (PPP) solution is available, this will
normally be output as the "Best" solution.
During PPP settling or should there be a PPP service outage, the position output
will automatically switch to the next, most accurate solution. In this way the
Differential GNSS solutions will be used as backup to the PPP solution.
In addition for comparison purposes a Differential GNSS solution may be output
from another port.
