Small Size High Precision Direction Finding Board
ER-GNSS-B06 Small Size High Precision Direction Finding Board is based on the second generation baseband chip of “Tianqin”. It can receive GNSS signals from full-frequency points of the whole constellation and fully support the reception of BDS-3 satellite signals. The new swan anti-interference technology is adopted to improve the performance under complex environment. The board card adopts the small size design of 28pin and is compatible with the mainstream direction finding board and can be used in precision agriculture, mechanical control, navigation and other high-precision applications.
Features
Full support for Beidou-3 satellite signal reception, full-frequency point direction finding of the whole constellation;
Support L-Band, can receive the “China precision” to realize single machine centimeter-level positioning;
New “Swan” anti-interference technology, complex environment performance is better;
Direction finding accuracy is better than 0.08°(@1.0m antenna distance);
Onboard IMU, provide tilt, roll and other attitude information;
28pin small size design, good compatibility.
