Guardian Stabilization
When coupled with our Guardian Stabilization Expander, the OSD Pro provides full featured stabilization and an Artificial Horizon display. Please see the
“Guardian Stabilization Expander” manual for more information.
“RADAR” Feature
The RADAR feature is an intuitive feature which makes it easier to keep track of your model’s location relative to home, and the direction of your model’s
travel relative to the direction the pilot is facing. See the Main Screen figure. The circular indicator in the center of the screen marks the takeoff point, in a
"bird's eye" view map. The RADAR location and direction of travel indicator (the chevron) indicates where you are in relation to home. The up direction is
configurable in the on-screen menus described below.
As your model moves relative to home, the chevron moves relative to the center of the screen. Also, the direction the chevron is pointing indicates the
direction the model is traveling, relative to home. So, if your model is flying toward home, the chevron will point toward home, regardless of where it is on
the display screen. The RADAR feature is the ultimate way to keep tabs on where you are relative to home, as an aid to piloting.
The RADAR feature is turned on and off via the PC software, as described in the Configuring Graphics Display section below, and can also be configured
via the OSD on-screen menus.
Return To Home
The Return To Home (RTH) feature will attempt to bring your plane to a “holding pattern” above the takeoff point if radio signal is lost, by manipulating
your model’s rudder/ailerons, elevator (or elevons), and throttle, based on your settings. GPS and other sensor information is used to attempt to return the
plane to home. The OSD Pro’s RTH has a unique feature that allows you to set two altitudes for returning to home, depending on how far away the model
is from home. See the “Safety Mode/Return to Home Information” section of the manual for more information on configuring Return To Home.
The Return to Home feature should work with any type of radio receiver – no special adapter is required.
Flight Timer
The OSD Pro provides a flight timer, which appears in the upper left-hand corner of the screen, when enabled. The Flight Timer feature is turned on and
off via the PC software, as described in the Configuring Graphics Display section below, and can also be configured via the “Flight Timer/Elapsed Time”
on-screen menu item.
The Flight Timer display is in MM:SS until greater than 59 minutes is reached, then it switches to HH:MM:SS. The flight timer starts counting up when the
GPS Home position is finalized. It can be reset to zero by clicking on the “Reset Home Position” menu item on the main on-screen menu.
Flight Summary (Display Max Values)
Maximum values for most of the text parameters chosen for display (and minimum voltage) can be displayed after your flight, automatically. For more
information, see the “Display Live or Max Values” on-screen menu item description in the “Main Menu” table, under the “Description of On-screen Menus”
section of the manual, below. Flight Summary mode is enabled by selecting the “Toggle” option.
Waypoints
The OSD Pro includes an innovative graphical display of up to 3 waypoints, on the main screen, as shown in the Main Screen figure. These are displayed
relative to the “Home” position, similar to the RADAR feature described above. When the OSD Pro is initialized, the first waypoint you entered is the
active waypoint (circled), and the “Distance to Waypoint” parameter (if you chose to display it) indicates the distance to the first waypoint. As each
waypoint is reached, the next defined waypoint becomes the active waypoint (it becomes circled), and the Waypoint Distance indicates the distance to the
next waypoint. After all the defined waypoints have been reached, the waypoint order reverses, and the next to last waypoint becomes the active waypoint.
NOTE: the OSD Pro will not autonomously fly to waypoints, and the waypoints must be within Visual Line of Sight (VLS) of “Home”. VLS is defined as
3 miles (4.8KM) So, care must be taken to ensure that you don’t configure waypoints farther than the VLS distance from the location you turn your model
on. Waypoints farther away than VLS will not appear on the main screen and an error message will appear.
Note: The format of waypoints entered into the software must be DDD MM SS.SS format. This is the format most commonly used by mapping software,
such as Google Earth and Google Maps. Note also that the GPS position displayed by the OSD Pro on the video is in a different format, called “GPS
Format.” This format is DDD.MM MM format. This format was chosen as it’s the standard format returned by GPS receivers.
Waypoints display is turned on and off via the PC software, as described in the Configuring Graphics Display section below, and can also be switched on
and off via the OSD on-screen menus.
Flight Simulator
The OSD Pro’s built in flight simulator simplifies testing the Return to Home feature, as well as testing alarms, voice prompts, and other features. Note that
you must have the OSD Pro’s servo channels connected to your receiver, and the “Servo Analysis Wizard” must be run, before using the simulator. See the
RTH Testing/Adjustment Procedures section for information on using the simulator. The simulator supports both traditional, fixed wing aircraft, and v-tail
or elevon controlled aircraft. NOTE: the simulator’s implementation is simplistic. It is not a full simulator based on the laws of physics. So, your model’s
operation in the air will be quite different than the characteristics observed in the simulator!
Displaying Flight Data in Google Earth and Charting Flight Data
Your eLogger or Data Recorder can log dat from all sensors during your flight. The data can be downloaded later, and either displayed with our powerful
charting software, or visulalized in Google Earth. Please see your eLogger or Data Recorder instruction manual for more information on how to do this.
