Ku - band equip & interface:
antenna - tbd side of fwd bulkhead
electronics - AV bay 3A, B
GPC interface = PF 1 (PL bus) (also sends T/M to GNC through FF 3)
D/L use "FM" mode - except space lab high rate
U/L: 2 voice channels, 1 CMD ([[?]]Inco's can add 1 text + graphic)
power: ~800 w (250 w from htrs) [~ twice as much as s-band high pwr] in comm mode; ~700 w in radar mode
constraints: single string; ops 2 req'd (no BFS cntl); doors must be open to deploy; can't xmit unless fully deployed
"safety" features: (1) U/L fail => comm swithches to s-band automatically (if that bit is set by cmd) (2) will automatically cut off if points toward orbiter
radar: range ([[?]] ~ 27 miles)(slow manually or GPC cmd)
rang rate (+/= .1 ft/sec)
az elev (from orbiter [[?]])
(displayed on A1 [[D&D]] disp, [[+/-]] on rel man display
use w/ univ ptg to denote tgt (an display
Item 4 - Ku band ENA - transfers GNC data to SM for antenna pointing)
(John Griffin owns radar)
