RTK Operation

INS401 requires RTCM 3.x format RTK correction

data. These corrections can be provided by

ACEINNA's OpenARC network, or by 3rd party

services supporting NTRIP protocol.

Multi-Band, Multi-Constellation

INS401’s

GNSS

chipset

is

based

on

ST

Microelectronics Teseo APP chipset. The Teseo APP

chipset baseband processor tracks various subsets

of constellations and bands. Teseo APP is connected

to the powerful on-board application processor,

which runs the firmware and algorithms.
