_____________________________________

(1) BDS B2b, GALILEO E6, QZSS L6, IRNSS L5 can be provided by firmware upgrade. BDS B2b is optional for 1408 channels.
(2) The measurement accuracy, precision, reliability and initialization time depend on various factors, including tilt angle, number of satellites, geometric distribution, observation time, atmospheric conditions and multi-path validation, etc. The data are derived under normal conditions.
(3) Irregular operations such as rapid rotation and high-intensity vibration may affect the inertial navigation accuracy.
(4) The battery operating time is related to the operating environment, operating temperature and battery life
(5) Accuracies are dependent on GNSS satellite availability. Hi-Fix Positioning ends after 5 minutes without differential data. Hi-Fix is not available in all regions, check with your local sales representative for more information.
