Processing strategy: Here you may select the strategy used for selecting the baselines to create the single-difference observation files for your network solution. In the automatic modes baselines will be formed in a way that all stations will be connected by a non-redundant set of baselines.
处理策略:在这里，您可以选择用于选择基线的策略，以便为您的网络解决方案创建单差异观察文件。在自动模式下，基线将通过一组非冗余基线连接所有站点的方式形成。
In general the option OBS-MAX guarantees the best performance for the processing of a network using correct correlations. In special cases a different option may be selected in order to optimize the number of observations for a station of special interest.
通常，OBS-MAX选件可使用正确的相关性来保证网络处理的最佳性能。 在特殊情况下，可以选择其他选项，以优化对特殊关注站点的观测数量。
OBS-MAX: The baselines are created taking into account the number of common observations for the associated stations. From all possible combinations, a set of baselines with maximum common observations is chosen.
OBS-MAX:基线的创建考虑到了相关站点的共同观测数量。从所有可能的组合中，选择一组具有最大共同观察值的基线
The number of observations are scaled to a sampling rate of one minute and to one frequency when the set of baselines is selected. In this way zero-difference files with different sampling rates are handled in a similar way.
选择一组基线时，观察次数将缩放为一分钟的采样率和一个频率。 这样，以不同的方式处理具有不同采样率的零差文件。
Remark: This strategy guarantees that a maximum number of observations from the network can be used in the double-difference processing. The procedure is, however, time consuming because the zero-difference observation files have to be analyzed several times.
备注：此策略保证在双差处理中可以使用来自网络的最大观察数。 但是，此过程很耗时，因为必须对零差观测文件进行多次分析。
SHORTEST：The non-redundant set of shortest baselines is created irrespective of the observation scenario of the stations. The strategy can only be used if the observations from all stations cover the same time interval.
最短的，无论站点的观测情况如何，都会创建最短基线的非冗余集。 仅当所有站点的观测值覆盖相同的时间间隔时，才可以使用该策略。
STAR: The baselines are built by connecting one reference station with all remaining stations. You may select the reference station manually. Otherwise the reference station will be selected automatically in a way that the sum of the length of all baselines is minimized.
STAR：通过将一个参考站与所有其余站连接来建立基线。 您可以手动选择参考站。 否则，将以最小化所有基线长度之和的方式自动选择参考站。
DEFINED: Only the "Predefined baselines" from a baseline definition file (see section "INPUT FILES") are created.
定义：仅创建基线定义文件中的“预定义基线”（请参见“输入文件”部分）。
MANUAL: Only one baseline is created. You have to select two zero-difference observation files and you may specify a name for the resulted single-difference observation file.
手动:只创建一个基线。您必须选择两个零差异的观察文件，并且可以为得到的单差异观察文件指定一个名称。by zzh_my@163.com
Remark: For the strategies OBS-MAX and SHORTEST you have the possibility to specify "Predefined baselines" from a baseline definition file in the section "INPUT FILES". The predefined baselines are created in any case. Additional baselines are built using the selected strategy to complete the set of baselines.
备注：对于OBS-MAX和SHORTEST策略，您可以在“输入文件”部分的基准定义文件中指定“预定义基准”。 在任何情况下都将创建预定义的基准。 使用所选策略构建其他基线以完成基线集。
Default value: OBS-MAX
