Changing the data stream rate

DIYDrones,

I've been tinkering with the ArduPlane code some.  I have written my own mavlink message that sends down specific information from the UAV.  In GCS_MAVLink I have written the function to send the message (just like all the other MAVLink mes

Multiple UAVs with one ground station

It seems that it isn't possible to connect multiple UAVs to Mission Planner.  What would be required to allow one ground station to monitor multiple UAVs in the air?  It seems like there was some intention to  implement this because each UAV can have

Telemetry MAVLink messages

DIYDrones,

I'm wondering if anyone can answer a simple question related to the MAVLink messages sent from the APM.  I am running a program that uses a XBEE via USB to monitor the messages sent from the APM. When I run this program, using an APM1, I se

APM1 vs APM2

Hello,

I have been experimenting with the APM hardware for almost 6 months now.  I have been able to write a custom MAVLink message to send down from the APM to my ground station.  So far, I have been able to successfully transmit this message using t

GUIDED waypoint Question

DIYDrones,

I was wondering if anyone could give me some more information on the exact information that is sent in the mavlink_waypoint_t structure when sending a guided waypoint.  I understand that current is set to 2 to distinguish a guided waypoint

Current Waypoint Index

Hello DIYDrones,

I was wondering where in the ArduPlane code is the current waypoint index is stored.  For instance, when the UAV is flying toward waypoint 1, where is the variable in ArduPlane that stores this value?  Furthermore, if the UAV was flyi

MAVLink NAV commands

DIYDrones,

I have two question related to MAVLink commands.  First, I'm trying to send a MAVLink command to my MAV which will make the plane fly to the desired waypoint and then continue on its mission.  For example, If the MAV's mission was A-B-C-D-H

ROS and APM using MAVlink

This summer I am in a program of students developing collision avoidance algorithms for UAVs.  They are testing/writing these algorithms in the ROS environment.  My goal this summer is to have the ability to communicate between then APM and the ROS e

ROS and APM using MAVlink

Currently, we have a fully operational ROS simulation so that we can test collision avoidance algorithms on it.  Information describing our current system is here.  Anyway, let me get to what I am trying to achieve this summer.  I intend to use the c
