|
|
|
#
|
|
|
|
|
# (1) TO CALCULATE THE REQUIRED DELTA V AND OTHER INITIAL CONDITIONS
|
|
|
|
|
# REQUIRED BY THE ACTIVE VEHICLE FOR EXECUTION OF THE TRANSFER
|
|
|
|
|
# PHASE INITITATION (TPI) MANEUVER, GIVEN --

|
|
|
|
|
|
# (A) TIME OF IGNITION TIG (TPI) OR THE ELEVATION ANGLE (E) OF
|

|
|
|
|
|
|
|
|
|
# (B) CENTRAL ANGLE OF TRANSFER (CENTANG) FROM TIG (TPI) TO
|
|
|
|
|
# INTERCEPT TIME (TIG (TPF)).
|
|
|
|
|
|
|
|
|
|
# (2) TO CALCULATE TIG (TPI) GIVEN E OR E GIVEN TIG (TPI).
|
|
|
|
|
|
|
|
|
|
# (3) TO CALCULATE THESE PARAMETERS BASED UPON MANEUVER DATA
|
|
|
|
|
# APPROVED AND KEYED INTO THE DSKY BY THE ASTRONAUT.
|
|
|
|
|
|
|
|
|
|
# (4) TO DISPLAY TO THE ASTRONAUT AND THE GROUND CERTAIN DEPENDENT
|
|
|
|
|
# VARIABLES ASSOCIATED WITH THE MANEUVER FOR APPROVAL BY THE
|
|
|
|
|
# ASTRONAUT/GROUND.
|
|
|
|
|
|
|
|
|
|
# (5) TO STORE THE TPI TARGET PARAMETERS FOR USE BY THE DESIRED
|
|
|
|
|
# THRUSTING PROGRAM.
|
|
|
|
|
#
|
|
|
|
|
# ASSUMPTIONS
|
|
|
|
|
|
|
|
|
|
# (1) LM ONLY -- THIS PROGRAM IS BASED UPON PREVIOUS COMPLETION OF
|
|
|
|
|
# THE CONSTANT DELTA ALTITUDE (CDH) PROGRAM (P33/P73).
|
|
|
|
|
# THEREFORE --
|
|
|
|
|
|
|
|
|
|
# (A) AT A SELECTED TPI TIME (NOW IN STORAGE) THE LINE OF SIGHT
|
|
|
|
|
# BETWEEN THE ACTIVE AND PASSIVE VEHICLES WAS SELECTED TO BE
|
|
|
|
|
# A PRESCRIBED ANGLE (E) (NOW IN STORAGE) FROM THE
|
|
|
|
|
# HORIZONTAL PLANE DEFINED BY THE ACTIVE VEHICLE POSITION.
|
|
|
|
|
|
|
|
|
|
# (B) THE TIME BETWEEN CDH IGNITION AND TPI IGNITION WAS
|
|
|
|
|
# COMPUTED TO BE GREATER THAN 10 MINUTES.
|
|
|
|
|
|
|
|
|
|
# (C) THE VARIATION OF THE ALTITUDE DIFFERENCE BETWEEN THE
|
|
|
|
|
# ORBITS WAS MINIMIZED.
|
|
|
|
|
|
|
|
|
|
# (D) THE PERICENTER ALTITUDES OF ORBITS FOLLOWING CSI AND
|
|
|
|
|
# CDH WERE COMPUTED TO BE GREATER THAN 35,000 FT FOR LUNAR
|
|
|
|
|
# Page 659
|
|
|
|
|
# ORBIT OR 85 NM FOR EARTH ORBIT.
|
|
|
|
|
|
|
|
|
|
# (E) THE CSI AND CDH MANEUVERS WERE ASSUMED TO BE PARALLEL TO
|
|
|
|
|
# THE PLANE OF THE PASSIVE VEHICLE ORBIT. HOWEVER, CREW
|
|
|
|
|
# MODIFICATION OF DELTA V (LV) COMPONENTS MAY HAVE RESULTED
|
|
|
|
|
# IN AN OUT-OF-PLANE MANEUVER.
|
|
|
|
|
|
|
|
|
|
# (2) STATE VECTOR UPDATED BY P27 ARE DISALLOWED DURING AUTOMATIC
|
|
|
|
|
# STATE VECTOR UPDATING INITIATED BY P20 (SEE ASSUMPTION (4)).
|
|
|
|
|
|
|
|
|
|
# (3) THIS PROGRAM MUST BE DONE OVER A TRACKING STATION FOR REAL
|
|
|
|
|
# TIME GROUND PARTICIPATION IN DATA INPUT AND OUTPUT. COMPUTED
|
|
|
|
|
# VARIABLES MAY BE STORED FOR LATER VERIFICATION BY THE GROUND.
|
|
|
|
|
# THESE STORAGE CAPABILITIES ARE LIMITED ONLY TO THE PARAMETERS
|
|
|
|
|
# FOR ONE THRUSTING MANEUVER AT A TIME EXCEPT FOR CONCENTRIC
|
|
|
|
|
# FLIGHT PLAN MANEUVER SEQUENCES.
|
|
|
|
|
|
|
|
|
|
# (4) THE RENDEZVOUS RADAR MAY OR MAY NOT BE USED TO UPDATE THE LM
|
|
|
|
|
# OR CSM STATE VECTORS FOR THIS PROGRAM. IF RADAR USE IS
|
|
|
|
|
# DESIRED THE RADAR WAS TURNED ON AND LOCKED ON THE CSM BY
|
|
|
|
|
# PREVIOUS SELECTION OF P20. RADAR SIGHTING MARKS WILL BE MADE

# THRUSTING MANEUVER.
|

|
|
|
|
|
|
# (5) THE ISS NEED NOT BE ON TO COMPLETE THIS PROGRAM.
|
|
|
|
|
|
|
|
|
|
# (6) THE OPERATION OF THE PROGRAM UTILIZES THE FOLLOWING FLAGS --
|
|
|
|
|
#
|

|
|
# ACTIVE VEHICLE FLAG -- DESIGNATES THE VEHICLE WHICH IS
|
|

|
# PURPOSE
|
|
|
|
|
#
|
|
|
|
|
# (1) TO CALCULATE THE REQUIRED DELTA V AND OTHER INITIAL CONDITIONS
|
|
|
|
|
# REQUIRED BY THE ACTIVE VEHICLE FOR EXECUTION OF THE NEXT
|
|
|
|
|
# MID-COURSE CORRECTION OF THE TRANSFER PHASE OF AN ACTIVE
|
|
|
|
|
# VEHICLE RENDEZVOUS.
|
|
|
|
|
#
|
|
|
|
|
# (2) TO DISPLAY TO THE ASTRONAUT AND THE GROUND CERTAIN DEPENDENT
|
|
|
|
|
# VARIABLES ASSOCIATED WITH THE MANEUVER FOR APPROVAL BY THE
|
|
|
|
|
# ASTRONAUT/GROUND.
|
|
|
|
|
#
|
|
|
|
|
# (3) TO STORE THE TPM TARGET PARAMETERS FOR USE BY THE DESIRED
|
|
|
|
|
# THRUSTING PROGRAM.
|
|
|
|
|
#
|
|
|
|
|
# ASSUMPTIONS
|
|
|
|
|
#
|
|
|
|
|
# (1) THE ISS NEED NOT BE ON TO COMPLETE THIS PROGRAM.
|
|
|
|
|
#
|
|
|
|
|
# (2) STATE VECTOR UPDATES BY P27 ARE DISALLOWED DURING AUTOMATIC
|
|
|
|
|
# STATE VECTOR UPDATING INITIATED BY P20 (SEE ASSUMPTION (3)).
|
|
|
|
|
#
|
|
|
|
|
# (3) THE RENDEZVOUS RADAR IS ON AND IS LOCKED ON THE CSM. THIS WAS
|
|
|
|
|
# DONE DURING PREVIOUS SELECTION OF P20. RADAR SIGHTING MARKS
|
|
|
|
|
# WILL BE MADE AUTOMATICALLY APPROXIMATELY ONCE A MINUTE WHEN
|
|
|
|
|
# ENABLED BY THE TRACK AND UPDATE FLAGS (SEE P20). THE
|
|
|
|
|
# RENDEZVOUS TRACKING MARK COUNTER IS ZEROED BY THE SELECTION OF
|
|
|
|
|
# P20 AND AFTER EACH THRUSTING MANEUVER.
|
|
|
|
|
#
|
|
|
|
|
# (4) THE OPERATION OF THE PROGRAM UTILIZES THE FOLLOWING FLAGS --
|
|
|
|
|
#
|
|
|
|
|
# THE ACTIVE VEHICLE FLAG -- DESIGNATES THE VEHICLE WHICH IS
|
|
|
|
|
# DOING RENDEZVOUS THRUSTING MANEUVERS TO THE PROGRAM WHICH
|
|
|
|
|
# CALCULATES THE MANEUVER PARAMETERS. SET AT THE START OF
|
|
|
|
|
# EACH RENDEZVOUS PRE-THRUSTING PROGRAM.
|
|
|
|
|
#
|
|
|
|
|
# FINAL FLAG -- SELECTS FINAL PROGRAM DISPLAYS AFTER CREW HAS
|
|
|
|
|
# SELECTED THE FINAL MANEUVER COMPUTATION CYCLE.
|
|
|
|
|
#
|
|
|
|
|
# EXTERNAL DELTA V FLAG -- DESIGNATES THE TYPE OF STEERING
|
|
|
|
|
# REQUIRED FOR EXECUTION OF THIS MANEUVER BY THE THRUSTING
|
|
|
|
|
# PROGRAM SELECTED AFTER COMPLETION OF THIS PROGRAM.
|
|
|
|
|
#
|
|
|
|
|
# (5) THE TIME OF INTERCEPT (T(INT)) WAS DEFINED BY PREVIOUS
|
|
|
|
|
# COMPLETION OF THE TRANSFER PHASE INITIATION (TPI) PROGRAM
|
|
|
|
|
# (P34/P74) AND IS PRESENTLY AVAILABLE IN STORAGE.
|
|

# (6) ONCE THE PARAMETERS REQUIRED FOR COMPUTATION OF THE MANEUVER
|
|
|
|
|
# HAVE BEEN COMPLETELY SPECIFIED, THE VALUE OF THE ACTIVE
|
|
|
|
|
# VEHICLE CENTRAL ANGLE OF TRANSFER IS COMPUTED AND STORED.
|
|
|
|
|
# THIS NUMBER WILL BE AVAILABLE FOR DISPLAY TO THE ASTRONAUT
|
|
|
|
|
# THROUGH THE USE OF V06N52
|
|
|
|
|
#
|
|
|
|
|
# THE ASTRONAUT WILL CALL THIS DISPLAY TO VERIFY THAT THE
|
|
|
|
|
# CENTRAL ANGLE OF TRANSFER OF THE ACTIVE VEHICLE IS NOT WITHIN
|
|
|
|
|
# 170 TO 190 DEGREES. IF THE ANGLE IS WITHIN THIS ZONE THE
|
|
|
|
|
# ASTRONAUT SHOULD REASSESS THE INPUT TARGETING PARAMETERS BASED
|
|
|
|
|
# UPON DELTA V AND EXPECTED MANEUVER TIME.
|
|
|
|
|
#
|
|
|
|
|
# (7) THIS PROGRAM IS SELECTED BY THE ASTRONAUT BY DSKY ENTRY --
|
|
|
|
|
#
|
|
|
|
|
# P35 IF THIS VEHICLE IS ACTIVE VEHICLE.
|
|
|

# THIS SUBROUTINE COMPUTES THE REQUIRED INITIAL VELOCITY VECTOR FOR
|
|
|
|
|
# A TRAJECTORY OF SPECIFIC TRANSFER TIME BETWEEN SPECIFIED INITIAL
|

|
|
# AND TARGET POSITIONS. THE TRAJECTORY MAY BE EITHER CONIC OR
|
|
|
|
|
# PRECISION DEPENDING ON AN INPUT PARAMETER (NAMELY, NUMBER OF
|
|
|
|
|
# OFFSETS). IN ADDITION, IN THE PRECISION TRAJECTORY CASE, THE
|
|
|
|
|
# SUBROUTINE ALSO COMPUTES AN OFFSET TARGET VECTOR, TO BE USED
|
|
|
|
|
# DURING PURE-CONIC CROSS-PRODUCT STEERING. THE OFFSET TARGET
|
|

# VECTOR IS THE TERMINAL POSITION VECTOR OF A CONIC TRAJECTORY WHICH

# HAS THE SAME INITIAL STATE AS A PRECISION TRAJECTORY WHOSE

# TERMINAL POSITION VECTOR IS THE SPECIFIED TARGET VECTOR.
