Description
The MeasurementTwoWayDoppler object is a container for measurement noise, minimum and maximum values, and an Estimable Bias for this measurement. This object is not creatable in script, but is always created as a child object of any measurement object that contains two way Doppler data as seen in the example below:
GroundStation1.Antenna.OD.TDRSObservation.TwoWayDoppler.Noise = 0.001;
Users cannot create instances of this type of object. However, users can access instances of this object type that have been created indirectly, for example as children of other objects. Users can also access any static properties and methods on this object type.
Inheritance Hierarchy: Object->MeasurementTwoWayDoppler

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.
