The LabSat is set up according to the diagram opposite.

1. Connect power to the LabSat.

2. Connect the Active GPS antenna to the RF IN port of the LabSat.

3. Connect the high speed USB cable to the computer on which the

Scenario data file is to be recorded. It is possible to connect an

external USB drive to the computer and stream the recorded file

directly onto this drive.

4. Start the LabSat software.

Before recording Scenario data it is important to observe certain criteria,

failure to follow these precautions may result in satellite data dropouts or

corrupt data contained within the recorded file.

Very Important: Running Background Applications if Logging to Computer

The LabSat has a two second USB buffer, but due to the exceptionally high data rates and processing power utilised by the LabSat USB bus when

recording GPS L1 data, it is important to have no other applications running on the computer and not to start any other applications whilst the

LabSat is recording data. Also make sure you do not start to move windows around, or do anything which takes processing power away from the

LabSat application, as Windows can occasionally stall for more than 2 seconds when launching/running other applications. Even though you may

have multiple USB ports on your computer, in most cases they all share the same bus. Therefore try to limit any activity using additional USB

devices.

Recording Data to an External Drive:

It is recommended that any external drive used to record scenarios is formatted in the NTFS format. The FAT32 format has a file size limit of 4 GB,

which is equivalent to about 34 minutes of recording. The USB drives supplied with the LabSat are pre-formatted using the NTFS file format.

5. Once the LabSat software is running, LabSat is now ready to record data.

6. Click the Browse Button. The user will be prompted to enter the filename and choose the location of the recorded file.
