GPS network simulations: How do I generate the text records required for GPS vectors?
Using GeoLab you can generate a coordinate difference observation group using the Edit/Insert/Coordinate Obs command when you have a text window open (ensure that you place your text cursor (the blinking one) at the point in your text window where you want the group inserted). You can select a number of options in the dialog box presented to generate the type of group you require. Once the group of records is inserted into your text file, you can edit it using the GeoLab Record Editor (Edit/Edit GeoLab Text Record menu command).
