1.E-RTK, BeiDou B3 signal used in RTK calculate engine;
concern the current situation, this mode can be used in
APAC; 2.ComNav Technology will remove UHF
modern according to
different country’s regulation
;
3 .410-470 MHz, 3 frequency range, 410-430, 430-450,
450-470 4.Radio work distance is related with many
environment factors, the maximum distance is 5 km in
very optimised situation; 5.Power consumption will
increase if using internal UHF as transmitter.
