File Naming Convention - ashtech GG Surveyor Reference Manual

File Naming Convention

The files are automatically named according to a convention that includes the site
name, session, and day of the year. Figure 4.5 outlines the file naming convention.
The one exception are almanac files that are named ALMyy.ddd where yy are the last
two digits of the year and ddd is the day of the year.

Data Modes
There are two different modes that the receiver can record in. These modes are
referred as data modes or data types. Each mode records different types of data and
can only be changed using the serial port command $PASHS,RNG. Table 4.3
describes these modes. The default is 0.

Figure 4.5: GG Surveyor File Naming Convention
The first letter of each file name is the file type B, S, C, E, M, or D.
The next 4 characters of each file name is the site ID. If the user has not
entered a site ID during the course of the recording session then these 4
characters are replaced by underscores ("____"). In kinematic surveying it is
common to change the site ID many times during the recording session. The
site ID used for naming the session files is the LAST site ID entered during
the session.
The next character indicates the session identifier. This field automatically
increments from A to Z when a new recording session is started. This fields
begins at A for the files associated with the first recording session within a
particular work day directory, and increments to Z as more sessions are
created in the same directory. After 26 files are created the session identifier
resets back to A, and the first character of the year will change to A.
The next two characters are the last two digits of the year (e.g. 97).
The file extension is the day of the year (e.g. Jan. 1 is day 001; Dec. 31 is day
365).
