  2. Bernese格式文件(在BSWUSER52目录下的文件内容)
  3. CODE产品文件
  4. CODE在处理后的文件
  5. CODE-MGEX产品文件(多卫星)

1.通用说明

  • 所有文件名都是大写。
  • 大部分文件都是UNIX压缩(后缀是.Z)。
  • 文件名中时间的缩写采用格式如下(自Bernese5.0开始也采用):
    使用的时间        菜单 时间
    缩写             变量               说明

  1. Bernese格式文件(在BSWUSER52目录下的文件内容)

Bernese用户区域的主目录树可以区分伯尔尼不同GNSS软件版本。 目前我们有仅BSWUSER52。
随着未来发展,如果新格式的引入,可能会出现新的顶级目录,如BSWUSER53。 如果有子不同版本的目录包含完整的目录文件,将采用各自的格式。 如果两个版本中的有相同各的文件,将出现在两个子目录中。
目录 简短的文件内容说明
------------------ ------------------------------------------
BSWUSER52 5.2版本BSW格式文件
ATM Bernese对流层和电离层文件
GEN 通用 BSW 文件
ORB Bernese clock, ERP, 和 DCB 文件
STA Bernese 站坐标文件
有些产品文件存储在年目录下,例如
http://www.aiub.unibe.ch/download/BSWUSER52/ATM/yyyy/

提醒:
不在提供5.0版本的特定文件。
