/ VN-200

VN-200 is a compact, high-performance GNSS-aided inertial navigation system (GNSS/INS) that combines a 3-axis gyro, accelerometer and magnetometer, a highly sensitive GNSS receiver, and advanced Kalman filtering algorithms to determine position, velocity, , and gives the best estimate of the pose.

Introduced in 2012, the VN-200 is the world's first GNSS-aided inertial navigation system (GNSS/INS) in a single surface mount package. The postage stamp-sized VN-200 SMD requires only a single 3.2-5.5V power supply and can be directly integrated into the user's electronic equipment.

The VN-200 Rugged is a "plug and play" version of the VN-200 SMD. The VN-200 Rugged is housed in a clamshell precision anodized aluminum enclosure that further protects the internal inertial sensors, GNSS receiver and electronics. Interface with the module is through a locking 10-pin connector and an MMCX connector for an external active GNSS antenna.

*1 Requires proper magnetic declination, proper magnetic environment, and valid hard/soft iron calibration.
*2 When there is enough movement for dynamic alignment.
* 3 It is fixed in units of parts. It can be calibrated during system integration using boresighting or other alignment processes.
*4Equipped with SBAS, clear view of GNSS satellites, good multipath environment, compatible GNSS antenna, 24-hour measurement.
*5 Typical rate of increase in position estimate error after loss of GNSS signal if the INS was fully adjusted before the loss of GNSS signal.
