Re: [Paparazzi-devel] Ground Station Communication Stuff

[Pascal Brisset]

Something similar to the Man Over Board (basic.xml:50) procedure, with 
no throttle

   <block name="spiral">
     <call fun="NavSetWaypointHere(WP_MOB)"/>
     <set value="DEFAULT_CIRCLE_RADIUS" var="nav_radius"/>
     <circle vmode="throttle" throttle="0.0" radius="nav_radius" wp="MOB"/>
   </block>

--Pascal
