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.

APPLICATION OF S82 RTK GPS

Brief introduction about S82.

RTK SURVEY MODE - CONNECT ALL COMPONENTS OF S82

For base:

1 tripod is accurately centered and leveled over the point (the point could be known point or unknown point)

2 position the base mainframe on the tripod.
