2.2.24 PPPDYNAMICSEED

Seed the PPP filter in any platform motion state
Platform: OEM729, OEM719, OEM7700
This command enables seeding of the PPP engine regardless of the receiver motion state. Accur-
ate seeds can be used to improve initial PPP convergence and re-convergence following signal
outages.
The seed position given by the PPPDYNAMICSEED command must be in a datum consistent
with the PPP corrections that are in use. For NovAtel CORRECT with PPP, the datum is ITRF2008.
The dynamic seed's time must refer to receiver time and cannot be more than 15 seconds in the
past. A valid PPP solution (the PPPPOS log solution status is SOL_COMPUTED) must have been
computed for the same epoch as the seed in order for the seed to be used.
See the PPPSEED command for stationary-only seeding and for other control over seeding.
