This document describes the OpenVario serial port protocol.
Version: 1.1
The OpenVario serial port protocol is built around the $POV
NMEA sentence:
$POV,<type>,<value>,<type>,<value>,...*<checksum>
A $POV
sentence can contain multiple datapoints that are defined by type
and value
. The type
part is a letter or number describing the type of the following value according to the following overview of supported types. The value
part is a floating point number for all currently supported types of datapoints. Future versions of the protocol may support other value types too though.
The list of datapoints should be terminated with the usual asterisk and two character checksum.
The following section describes all datapoints supported by the current version of the OpenVario protocol.
S
: true airspeed inkm/h
Example:$POV,S,123.45*05
-
P
: static pressure inhPa
Example:$POV,P,1018.35*39
-
Q
: dynamic pressure inPa
Example:$POV,Q,23.3*04
-
R
: total pressure inhPa
Example:$POV,R,1025.17*35
T
: temperature in °C
Example:$POV,T,23.52*35
E
: TE vario in m/s
Example:$POV,E,2.15*14
