This command enables seeding of the PPP engine regardless of the receiver motion state. Accurate 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 TerraStar corrections, the datum is ITRF2014. 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.
