NAVSIGHTHM.1.5
2.3.3. Internal GNSS (Septentrio Asterx-4, HW Revision <= 2.1)
The NAVSIGHT-S embed a very high end, survey grade, dual antenna, Septentrio AsterX-4 GNSS receiver
that is perfectly fitted for the very demanding survey market.
It features L1/L2/L5 and L-Band signals tracking and uses GPS, GLONASS, BEIDOU and GALILEO
constellations to provide very accurate and reliable measurements even in harsh environments.
The internal dual L-Band demodulator supports Fugro Marinestar
™
PPP services to delivery world wide, with
no specific infrastructure, a positioning accuracy better than 10 cm.
This latest generation GNSS receiver also features very accurate RTK positioning with the world's leading
signal availability and minimal re-acquisition time after a GNSS outage. This receiver provides best accuracy
and reliability in harsh GNSS environments thanks to a very advanced auto mitigating algorithm that
detects and eliminates multi-path situations or Inmarsat / Iridium jamming.
