The   main function

1   BD-2 with a single positioning system, GPS positioning system alone, BD-2 +   GPS positioning function combination;

2 BD-2 with a single directional system, GPS system of   single directional, BD-2 + GPS positioning and orientation combination.

Positioning   Indicator

Positioning   mode

The default mode is a combination of BD-2   + GPS positioning. BD-2 can be switched by a single command system, GPS   system or a single BD-2 + GPS positioning combinations.

positioning   accuracy

Horizontal accuracy: 7.5m (1σ)

Vertical accuracy: 10m (1σ)

Directional   Indicators

Directional   mode

The   default mode is a combination of BD-2 + GPS orientation, if a satellite to   the satellite tracking system does not, then automatically BD-2 alone or GPS   orientation. BD-2 can be switched by a single command system, GPS system or a   single BD-2 + GPS combination orientation
