(1) RMS, incremental error growth from steady state accuracy. Post-processing results using third party software;
(2) Under ideal conditions that include proper static alignment and in-field dynamic motions during loss of GNSS signal;
(3) 2 meters base line between two GNSS antennas;
(4) tracks up to 60 L1/L2 satellites;
(5) 50 Hz while tracking up to 20 satellites. 20 Hz position update rate for Basic model of INS;
(6) dynamic accuracy may depend on type of motion;
(7) time accuracy does not include biases due to RF or antenna delay;
(8) If tracking GPS only;
(9) Weight and size are PN dependent. Customers should obtain the most recent 2D/3D files before designing any interface hardware;
