SDI-COMPASS is GPS heading and positioning product which uses a dual antenna for heading measurement and GPS positioning .It assembles gyroscope and angular sensor which can measure heading and pitch angle under dynamic state and static state.According to antenna baseline,accuracy of heading measurement can reach 0.25°~0.1°.
FEATURES
·Low power consumption
·High speed of positioning, heading, recapture
·Accuracy of heading measurement can not be affected by magnetic field
