    Message Download and Download COM/PRV/DIAG vs Export data: What is the difference?

    Message download and Download COM/PRV/DIAG are useful for large amounts of data; unlimited messages from the past 10 days can be downloaded (but not displayed) using these functions. The export function allows you to export a limited number of messages from the data table or the map page. For example, up to 1 500 messages can be exported from the data table and up to 10 000 messages can be exported from the map page.

    Choose the format (date, location, decimal separator…) your data should appear in by clicking on Preferences in the left menubar. Then select the Display tab.

How to display additional parameters to qualify the ellipse of error for location classes 0, 1, 2, 3

To display Diagnostic Data, click in the checkbox next to when you download your data, then click on Download.

For the values corresponding to the ellipse of error, please refer to this table:

Column title Error radius Semi-major axis Semi-minor axis Ellipse orientation GDOP*
Units Meters Meters Meters Degrees (from North when heading East) m/Hz

*Geometric Dilution of Precision (GDOP) is a measure of the effect of the geometry of the satellite-beacon configuration on location accuracy. The actual Argos location accuracy depends on both the GDOP value and the quality of the transmitter (frequency stability). As a general rule, a smaller GDOP value yields a more accurate position.
