SPLITBOXUM.1.2
1.3. SplitBox Septentrio specifications (models -S)
The SPLITBOX-STD-S and SPLITBOX-SUB-S embed a very high end, survey grade, dual antenna, Septentrio
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 Terrastar and Veripos Precise Point Positioning (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 GPS outage. With a refresh rate of 20Hz, 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.
