Hi, friends

How to import the position (latitude and longitude) from Mission Planner in python?

Thank you

Just create a listener for the GLOBAL_POSITION_INT mavlink message:

Can you show me how (and where) do I have to write this in my code?

import sys
import clr
import time
import math
import MissionPlanner #import *
clr.AddReference(“MissionPlanner.Utilities”) # includes the Utilities class
print 'Starting Mission’
Script.ChangeMode(“Guided”) # changes mode to "Guided"
print 'Guided Mode’
item = MissionPlanner.Utilities.Locationwp() # creating waypoint
lat1=-3.780854
lon1=-38.541491
lat2=-3.779830
lon2=-38.541590 # Longitude value
alt = 100 # altitude value
dla=(lat1-lat2)601852
dlo=(lon1-lon2)601852
dist=math.sqrt(dla2+dlo2)
MissionPlanner.Utilities.Locationwp.lat.SetValue(item,lat2) # sets latitude
MissionPlanner.Utilities.Locationwp.lng.SetValue(item,lon2) # sets longitude
MissionPlanner.Utilities.Locationwp.alt.SetValue(item,alt) # sets altitude
MAV.setGuidedModeWP(item) # tells UAV “go to” the set lat/long @ alt
print ‘Going to Point 1’

Take a look at http://ardupilot.org/planner/docs/using-python-scripts-in-mission-planner.html

Longitude and latitude are stored at Class Name: CurrentState.cs Python Variable: cs. You can access them via cs.lng and cs.lat.

Example:

print 'Start Script'
import clr
clr.AddReference("System.Windows.Forms")
clr.AddReference("System.Drawing")

from System.Windows.Forms import Application, Form
from System.Windows.Forms import ComboBox, Label, Button
from System.Drawing import Size, Point
from MissionPlanner import MAVLinkInterface


class IForm(Form):

def __init__(self):

    self.Text = "Script Check"
    self.Size = Size(240, 240)
    
    self.button1 = Button()
    self.button1.Text = 'Press Me'
    self.button1.Location = Point(25, 125)
    self.button1.Click += self.update
    
    self.Controls.Add(self.button1)
         
def update(self, sender, event):
    print "button clicked\ncurrent position lat, lng: %.2f , %.2f" % (cs.lat, cs.lng)


Application.Run(IForm())
