Description:

The Homer-V3 is a 'telemetry-transmitter-module'. Its fondly nicknamed 'homer' in daily use, because pilots 'home in' on this module during approach procedures.

Dock homer to a radio-silent vessel (a vehicle without transponder capability) to keep track of that vessel's location and to receive ILS data when approaching it.

Homer was tested and calibrated using channel 248 and 249 (120.40 MHz and 120.45 MHz respectfully), but isn't limited to this channel-set.

The picture shows a low-resolution computer rendered image of the Homer-V3.

Pilots Operating Manual:

Major warnings:

None

 
Advisories:

None

 
Current list of 'proposed handling' for various scenarios:

T/O
As payload on launch vehicle

Landing
Not advised/no current proposed procedures

Docking
#1:Request docking clearance (not needed for module assembly dockings)
#2:Approach head-on and aim the HUD 'victor'-targetsights on center of target dockring by linear-thruster movement.

Broadcast activation in earlier versions of homer was activated manualy, but is now automated (provided homer's onboard flight-computer is programmed before launch)
To program it; indclude this entry to the homer data-set:
XPDR 248
Channel 248 yields a frequency of 120.40 MHz (for another frequency, select another channel).
Homer should now start broadcasting the transponder signal automaticaly when jettisoned from the spaceshuttle.
(See an example of what homer's data-set might look like with the transponder channel programmed in the scenario.scn datafile: scenario-example )
