Introduction
The “Raven
2 PRO
” is one component of RC Electronics model aircraft telemetry system. The
unit is the
“on
-
board” unit intended to be used with the “Snipe
/ Finch
” “
g
round station”. The
unit is designed to
measure many parameters of an R/C model aircraft and transmit them to the ground station via the
telemetry link working on 433 MHz frequency. The unit is capable of measuring sink/climb rate (Vario),
airspeed, altitude, acceleration of the plane in all axes, noise level, servo pulse on servo input, GPS data
with 18Hz refresh rate and supply voltage. For storage it has internal fast solid state storage which is will
record up to 20h of flying.
