Access



Name Description
AER Data Provides azimuth, elevation, and range related information for the relative position vector between the base object and the target object. The information is available in a variety of coordinate axes.
Access Data Reports information concerning the start and stop time of each access interval.
Access Gaps Reports intervals where access does not exist between the objects.
Access Intervals by Constraint Reports the intervals satisfying each constraint in the constraint set computed for the access, in the order in which the constraints were applied.
Access Intervals by Time Reports the intervals satisfying each constraint in the constraint set computed for the access, in the order of the satisfaction intervals of each constraint.
Access Schedule Reports access intervals in a format that can be import by Microsoft Scheduler+. All fields are declared unitless and are returned as strings.
Active Constraints Lists the constraints that are applied in computing the access.
All Boundary Access Reports the access time intervals when all of the AreaTarget/LineTarget's boundary points have access simultaneously. One object used in the access must be an AreaTarget or LineTarget.
Allowed Times Reports the time intervals over which access between the two objects may be computed (i.e., the availability intervals for these objects).
Area Collection Angle Reports the access time intervals and the collection angle at the point of closest approach to the AreaTarget centroid during each interval. One of the objects must be an AreaTarget.
Boundary Minimum Range Reports the time of minimum range from each boundary point of an AreaTarget/LineTarget to the other access object. One object used in the access must be an AreaTarget or LineTarget.
Boundary Point Access Reports access intervals for each boundary point of an AreaTarget/LineTarget. One object used in the access must be an AreaTarget or LineTarget.
Configuration Reports access computational settings.
Considered Times The time intervals over which access was computed.
Constraint Sample Stats Reports statistics of the sampling applied for each constraint of the access.
Constraint Samples Reports constraint sampling.
Event Times Reports events during each access interval.
From Position Velocity Report position and velocity information of the base object.
Link Information Link information provides the link budget for a single access between a transmitter and a receiver.
LLA Grazing Point Reports the grazing point along the line of the sight between the objects involved in the access (i.e., the closest point to the central body ellipsoid along the line segment between the objects). The location is expressed in detic coordinates.
LLR Grazing Point Reports the grazing point along the line of the sight between the objects involved in the access (i.e., the closest point to the central body ellipsoid along the line segment between the objects). The location is expressed in centric coordinates.
Refraction Reports information of the effects of refraction on elevation angle, range, and propagation delay.
Rel Position Velocity The relative position and velocity, as viewed from the base object.
Sat Angles Data Reports angles to the target object from the base object of an access, with respect to the base object's local CBI VVLH frame (i.e., VVLH axes based on the CBI velocity of the base object).
Sensor Based Angles Reports the apparent angles to the target object from the base object, using the BodyFixed frame.
To Position Velocity Reports position and velocity information of the target object.
