iGate Download Options

Use these options to select reference stations from which to download. They are available in the Select Reference Stations to Download dialog when you download reference station data using the iGate protocol.

iGate is a rare protocol that can retrieve a network of multiple reference stations. Using the iGate protocol, you can download different types of data, such as observation and ephemeris, concurrently.


Options
Select	Leave this checked to download the reference station. Uncheck stations you do not want to download.
Station name	This identifies the reference station, which may or may not indicate its geographic location.
Interval (sec)	This displays the sample rate in seconds. Click the drop-down arrow to select a different interval. Note: If you select a higher rate than the rate at which the data was collected, you may not receive data. Experiment with lower rates if you think this is the case.
Ephemeris	Click the drop-down arrow to select an ephemeris type. Low accuracy - Select when none of the IGS orbit types are available. IGS Precise orbit - Select for the highest quality orbit data. This data is used for the IGS reference frame. IGS Rapid orbit - Select when IGS Precise orbit is unavailable. For many applications, IGS rapid orbit data is almost as good as IGS precise orbit data. IGS Ultra rapid orbit - Select when neither precise or rapid orbit data is available. For more information, see the International GNSS Service's web site. Note: If the server does not have the ephemeris type you select, no file is downloaded.
Distance	This displays the distance from the station to the center of your current project data.
