Raw Data Recording

Use this page to control raw data recording in the receiver outside of any programmed sessions.

 

The parameters are the following.

 

Parameter

Designation

$PASHS

Site Name

Enter a 4-character string identifying the site where data recording will take place. The following charac­ters are not allowed in the site name: / * . \ ,

SIT

Storage

Tell the receiver where to store the recorded raw data. On selecting a memory device (Internal Mem­ory or USB Device), you can read, underneath the field, the amount of free memory currently available on the selected device.

Selecting the USB device implies that you know there is one currently connected to the receiver.

MEM

Recording Ele­vation Mask

Enter the elevation mask angle in degrees (0-90°). The data from all the satellites located in the eleva­tion mask, seen from the recording site, will not be recorded.

ELM

Data Type

A read-only field listing the type of raw data mes­sages currently set to be recorded by the receiver.

Data Recording

Set this option to enable raw data recording in the receiver right after you have clicked on the Config­ure button at the bottom of this page. You can also keep this option cleared and later start data record­ing by pressing the Log button on the receiver front panel.

REC

Recording In­terval

Enter the raw data recording rate, in seconds. De­pending on the installed firmware option, this value can range from 0.05 s, 0.1 s or 0.5 s to 999 s.

DRI

Ring File Buffer Mode

This option is used to allow the receiver to deliver only the last x minutes of raw data decoded by the receiver (the “x” minutes are defined in the File Du­ration parameter below). Older raw data will not be kept in receiver memory.

With this option used, raw data are temporarily stored in the so-called “ring file” buffer before they are saved as a file. This will happen every time the end of the x minutes of data buffering is reached.

RFB

File Duration

(This field is visible only after Ring File Buffer Mode has been enabled).

Indicate the time span, in minutes, that the ring file buffer should cover. For example setting this field to “15” means that at all times, the receiver will be able to provide a record file containing the last 15 min­utes of raw data decoded by the receiver.
