Net::GPSD3::Return::TPV(3pm) User Contributed Perl Documentation Net::GPSD3::Return::TPV(3pm) NAME
Net::GPSD3::Return::TPV - Net::GPSD3 Return TPV Object SYNOPSIS
printf "Time: %s, Lat: %s, Lon: %s ", $object->time, $object->lat, $object->lon; DESCRIPTION
Provides a Perl object interface to the Time-Velocity-Position (TVP) object returned by the GPSD daemon. Example JSON objects: Protocol 3.1 Versions { "class":"TPV", "tag":"MID2", "device":"/dev/ttyUSB0", "time":1253593085.470, "ept":0.005, "lat":38.88945123, "lon":-77.03522143, "track":171.7249, "speed":0.467, "mode":2 } { "class":"TPV", "tag":"MID2", "device":"/dev/ttyUSB0", "time":1253593667.430, "ept":0.005, "lat":38.88945123, "lon":-77.03522143, "alt":146.911, "track":180.0000, "speed":0.194, "climb":-0.157, "mode":3 } Protocol 3.4 Version { "class":"TPV", "tag":"0x0106", "device":"/dev/cuaU0", "time":"2011-03-20T06:51:59.12Z", "ept":0.005, "lat":37.371427205, "lon":-122.015179890, "alt":25.789, "epx":1.926, "epy":1.808, "epv":6.497, "track":0.0000, "speed":0.000, "climb":0.000, "eps":3.85, "mode":3 } METHODS PROPERTIES
class Returns the object class string Returns the JSON string parent Return the parent Net::GPSD object device Name of originating device. tag Type tag associated with this GPS sentence; from an NMEA device this is just the NMEA sentence type. mode NMEA mode: %d, 0=no mode value yet seen, 1=no fix, 2=2D, 3=3D. time Seconds since the Unix epoch, UTC. The value may have a fractional part of up to .01sec precision. Note: In 2.96 (protocol 3.4) the TPV->time format changed from unix epoch to W3C, but this method hides that from the user. timestamp W3C formated timestamp value either directly from the protocol >= 3.4 or calculated < 3.4. The value may have a fractional part of up to .01sec precision. Note: I expect that in protocol 3.5 the value will be passed directly as TPV->timestamp datetime Returns a DateTime object lat Latitude in degrees: +/- signifies West/East lon Longitude in degrees: +/- signifies North/South. alt Altitude in meters. speed Speed over ground, meters per second. track Course over ground, degrees from true north. climb Climb (postive) or sink (negative) rate, meters per second. ept Estimated timestamp error (%f, seconds, 95% confidence). epx epy Latitude error estimate in meters, 95% confidence. epv Estimated vertical error in meters, 95% confidence. eps Speed error estimate in meters/sec, 95% confifdence. epd Direction error estinmate in degrees, 95% confifdence. epc Climb/sink error estinmate in meters/sec, 95% confifdence.

point Returns a GPS::Point Object BUGS
