APPLICATION OF TRACK MODE GPS

Raw data collect. For base, the method of data collecting is the same as control survey mode. For rover: you should choose track mode on the initial interface. Set collecting condition. If you set collecting interval to be 5 seconds and set the times of collection to be 3 times, it will take you 15 seconds to survey a points (interval 3 seconds and times 2, the time will be 6 seconds for every point, for example). When the condition is satisfied, mainframe will enter collecting status atuomatically. The interface is shown as figure. Note that the collection condition is satisfied means: NAV mode is 3d, pdop is less than 6.0 and locked satellites are more than 4.

Rover initialization.

Fix the rover on a point. Press F1 to initialize. The time needed in initializing course is 5 minutes, so i’ts critical to remian the rover immobile during initializing course. You’d better have a set of prism tripod to fasten the receiver. In the course, the corresponding screen menu will change into survey. When initialization is completed, the long beep wil tip you. After initialization, press F1 survey, mainframe will enter surveying status. when you reach the point which you want to survey, press F2 to save (the time needed depend on your setting) after hearing the beep, move to next target to collect. After complete data collecting, press F1 to initialize again (to get higher accuracy we suggest you initialize the receiver every hour). At last, press key and hold for a moment to exit the collecting program and all data will be stored automatically. Download raw data. The method of downloading is the same as control survey mode.
