APOGEEHM.1.5
2.2. Aiding sensors
Many different aiding sensors can be used to aid the Apogee INS.
2.2.1. Apogee-D internal GNSS receiver
The Apogee-D embed a very high end, survey grade GNSS receiver with dual antenna heading capability.
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 algorithms that detects and eliminates multi-path situations or Inmarsat / Iridium jamming.
