Differential

operation
The V200n delivers positioning accuracies of 2.5 m 95% and provides
positioning quality to better than 0.6 m 95% using differential corrections
received through the internal SBAS demodulator or through Atlas L-band.
SBAS Tracking
SBAS tracking
The V200n features two-channel tracking that provides an enhanced
ability to maintain a lock on an SBAS satellite when more than one
satellite is in view. This redundant tracking approach results in more
consistent tracking of an SBAS signal in areas where signal blockage of a
satellite is possible.
Atlas L-band
Atlas L-band
Atlas L-band corrections are available worldwide. With Atlas, the
positioning accuracy does not degrade as a function of distance to a base
station, as the data content is not composed of a single base station’s
information, but an entire network’s information.
The V200n can calculate a position with 30 cm RMS (horizontal) accuracy.
To configure the receiver to use Atlas L-band, a subscription must be
purchased.
