Reports

Name Description
AER

Reports azimuth, elevation, and range values for the relative position vector between the base object and the target object, during access intervals. The relative position includes the effects of light time delay and aberration as set by the computational settings of the access. Az-El values are computed with respect to the default AER frame of the selected object of the Access Tool, as described below.

Reference Frames in AER Reports

AER reports for accesses are based on a default local coordinate system for every type of STK object.

For facilities, places, and targets the local coordinate system is LH.

  • Azimuth is referenced to X, positive towards Y (clockwise from above).
  • Elevation is referenced to X-Y plane, positive along negative Z.

For aircraft, ships, and ground vehicles the local coordinate system is VVLH CBF (Central Body Fixed).

  • Azimuth is referenced to X, positive towards Y (clockwise from above).
  • Elevation is referenced to X-Y plane, positive along negative Z.

For satellites and missiles the local coordinate system is VVLH CBI (Central Body Inertial).

  • Azimuth is referenced to X, positive towards Y.
  • Elevation is referenced to X-Y plane, positive along negative Z.

For other objects, the local coordinate system is found using the object's parent (or grandparent) as applicable.

LH (Local Horizontal)

X axis = constrained toward local north
Y axis = local east
Z axis = aligned with local geodetic nadir

VVLH (Vehicle Velocity, Local Horizontal)

X axis = constrained toward velocity vector
Y axis = perpendicular to X and Z.
Z axis = aligned with geocentric nadir
AERSummary A report of the summary of azimuth, elevation, and range values (i.e., min/max/mean elevation and min/max/mean range) for each access interval, for the relative position vector between the base object and the target object. See the AER style for a description of the azimuth, elevation and range values being computed.
AOS Reports the start time of each access interval (i.e., the acquisition of signal (AOS).
Access Reports a list of the access intervals.
Access Configuration Reports access computational settings.
Access Detailed Creates a detailed report on the access and its intervals. In the first section of the report, the active constraints that were used in the access computation are listed. In the next section, each access interval is listed along with

  • the constraint (if any) that determined the start/stop time of the access,
  • the LLA positional elements of the base object at the start/end of each interval,
  • and the LLA positional elements of the target object at the start/end of each interval.

Access Intervals by Constraint Reports the satisfaction intervals of each access constraint used in the access computation.

The report is organized into subsections, where each subsection is an active constraint. Each subsection lists the intervals that the constraint's criteria is satisfied for that constraint (e.g., for a Minimum constraint, the intervals where the constraint value was greater than (or equal to) the specified minimum allowed value).

The subsections are reported in the order that the constraints were considered in the computation, with the intervals from the previous subsection being the input time intervals over which the current subsection's constraint was assessed for satisfaction. The first subsection's input interval was the requested analysis interval for the access; the last subsection's satisfaction intervals, being times that satisfied all the constraints, are the access intervals themselves.

Because of the cascade that uses the output satisfaction intervals from one constraint as the input intervals over which the next constraint is assessed, the satisfaction intervals for a reported constraint are not necessarily the entire intervals where the constraint's criteria might be satisfied had the requested access analysis interval been used as the input interval.
Access Intervals by Time Reports the satisfaction intervals of each access constraint used in the access computation.

The report is organized into subsections, where each subsection shows the cascade of satisfaction intervals for the active constraints used in the access computation, resulting ultimately in an access interval or with no visibility remaining. The cascade of intervals follows the order of the constraints as they were considered in the computation.

Each line in a subsection shows the constraint that was considered and its satisfaction interval during the interval from the previous line's satisfaction interval. The first line shows an interval of the first constraint's satisfaction intervals during the requested analysis interval; the last line shows either an access interval or that no visibility remains(if the constraint did not meet its satisfaction criteria during the cascade). A constraint is satisfied when it meets its specified criteria (e.g., for a Minimum constraint, the interval where the constraint value was greater than (or equal to) the specified minimum allowed value).

Because of the cascade that uses the output satisfaction intervals from one constraint as the input intervals over which the next constraint is assessed, the satisfaction intervals for a reported constraint are not necessarily the entire intervals where the constraint's criteria might be satisfied had the requested access analysis interval been used as the input interval.
Access Violated Constraints Reports the access intervals and for each interval, the constraint (if any) that determined the start/stop time of the access.
Access-IFT Reports a list of the access intervals, where the start and stop times of the intervals are expressed in Epoch Seconds.
AccessSummary A report of the min/max/mean summary of the durations of the access intervals.
Angular Rates A report of azimuth rate, elevation rate, angular rate, and range rate over time, during each access interval, from the perspective of the selected object in the Access Tool. The azimuth rate, elevation rate, and angular rate are available only if the selected object supports that metric as an access constraint: the value being reported is that as computed by that access constraint.

Link Budget - Detailed This Access report provides the detailed information for a communications link budget. Each line of the report conforms to a single time step (user specified) of the dynamic link. The link budget information flow in each line of the report follows the signal path. The link starts from a transmitter RF source and goes through the modulator, transmitter antenna, propagation through the RF environment, such as atmosphere, rain, fog, atmospheric scintillation, etc. The signal arrives at the receive antenna, passing through cables, low noise amplifies (LNA), and is finally demodulated at the receiver. The report provides the link information such as signal powers, RF propagation losses, environmental noise, and link performance at each stage of the signal propagation. The link performance parameters, C/N, Eb/No, and Bit Error Rate (BER), show the signal status without the presence of any interfering signals as well as under the presence of the interfering (jamming) signals.
Link Budget - Interference This Access report is a subset of the link budget report, showing key link budget parameters as in the Link Budget report style: EIRP, Frequency, RIP, Flux Density, g/T, C/No, Bandwidth, C/N, Eb/No, and BER. It also reports key link performance parameters under the presence of interfering signals, such as C/(No+Io), C/(N+I), C/I, Eb/(No+Io), and BER+I. Please refer to the link budget detailed report style for details.
