Description
The options for how the a priori covariance is handled through the iteration process.
Timing Precision Mode
This page describes functionality in millisecond timing precision mode. Millisecond timing precision mode is deprecated and will be removed in a future release. We recommend that you migrate your Mission Plans to nanosecond timing precision mode.

Attributes
Type:

integer
|
Access:
|
read/write
|
Default Value:
|
0 ( Use the user-specified covariance for all properties in the state vector. )

Valid Values:
|
Value
|
Label
|
0
|
Use the user-specified covariance for all properties in the state vector.
|
1
|
Don't seed the a priori state covariance at the start of each iteration. This effectively sets the inverse of the covariance to zero.
|
2
|
Ignore the a priori covariance for the initial iteration of the batch, and use the post-update computed covariance for subsequent iterations.
|
3
|
Compute the optimal a priori covariance for each iteration of the batch.
