1.. REMARKS
THE RAMP FOR THIS MISSION IS A MODIFIED SINUSOIDAL CURVE
OF 4800 SECONDS DURATION AND SYMMETRICAL ABOUT THE 2400 SECOND MARK.
IN ORDER TO PLOT THIS CURVE WE MUST EQUATE THE 4808 SECONDS TO ITS
EQUIVALENT IN DEGREES 210. THE CURVE REPRESENTS GROUND ANGULAR
VELOCITY (RADIANS/SECONDS) VS TIME (DEGREES). THE CURVE IS MADE
UP OF THREE SECTIONS EACH HAVING ITS UNIQUE EQUATION. FROM 0
DEGREES TO 60 DEGREES, THE EQUATION OF THE CURVE IS K SIN (THREE
HALFS X - 90 DEGREES). THE SEGMENT FROM 60 DEGREES TO 150 DEGREES
HAS THE EQUATION K SIN (2 X - 120 DEGREES) AND THE LAST SEGMENT
FROM 150 DEGREES TO 210 DEGREES IS DEFINED BY K SIN ( THREE HALFS
X - 45 DEGREES). THE TWO VARIABLES X AND K ARE GIVEN. "X" IS THE
TIME (DEGREES) OR SCALE ON THE ABSCISSA AND K IS GIVEN IN THIS CABLE
AS A GROUND ANGULAR VELOCITY VALUE. THE ORDINATE OF THE GRAPH
RANGES FROM THE "REFERENCE LEVEL" VALUE (GIVEN) IN GROUND ANGULAR
VELOCITY (RADIANS/SECOND) TO PLUS AND MINUS THE K VALUE WHICH
REPRESENTS THE AMPLITUDE OF THE CURVE. WITH THIS CURVE PLOTTED AND

(PASS OR SEGMENTS THEREOF) THE CAMERA RATES FOR THAT PASS CAN BE
FOUND. THE FOLLOWING CONVERSION FACTORS WILL ALLOW ONE TO GO
FROM GROUND ANGULAR VELOCITY TO CYCLE PERIOD TO SCAN VELOCITY TO
IMAGE MOTION COMPENSATION VELOCITY.
1. CYCLE PERIOD (SECONDS) EQUALS THE RECIPROCAL OF THE GROUND
ANGULAR VELOCITY (RADIUS PER SECOND) (11.0574)
2. SCAN VELOCITY (INCHES PER SECOND) EQUALS (24) (6.2834)
