*** BEGIN TUTORIAL # 3-3 ***
133505
Tutorial # 3-3 covers orbit circularization and transition to stationkeeping
133515
The LV is 3.0km below, 5.4km west, and 0.8km north of the OL
133525
The OL transponder is turned on to get a better fix on the LV position
133545
The LV is rolled into position, with the face axis pointing up
133555
Roll start
133655
Roll complete
133665
The LV is pitched back to the proper orientation for the circularization burn
133675
Pitch start
133695
Pitch complete
133715
The LV is about to pass by the OL, west-to-east
133760
The LV has passed the OL
133770
The circularization burn takes place when the LV is 1km east of the OL
133805
*** MAIN ENGINE ON ***
133810
*** MAIN ENGINE OFF ***
133840
The INS (in absolute position mode) reveals that the LV is falling rapidly
133850
The 6.2m/s drop can be stopped using the RCS face thruster
133855
..in order to circularize the orbit
133865
Circularization burn start
133885
Circularization burn complete
133895
The LV is put into the proper orientation for transition to stationkeeping
133900
..with the up axis pointed north and the face axis pointed up
133905
Yaw start
133955
Yaw complete
133975
Roll start .. to point the face axis 10° west of vertical
134000
Roll complete
134010
OL relative position is displayed during transition to stationkeeping
134030
The rendezvous autopilot is engaged
134035
..to move the LV to a point 300m south of the OL in about 30min
134045
The rendezvous autopilot uses the RCS thrusters
134055
At first they fire almost continuously
134105
After about 1min, they settle down and only fire occasionally
134160
The DSN transponder is turned off as the LV approaches the OL
134220
The LV is 3100m below, 790m east, and 820m north of the OL
134280
The LV is 3000m below, 610m east, and 780m north of the OL
134340
The LV is 2900m below, 450m east, and 720m north of the OL
134390
The LV must be rolled 21° west every 7min to maintain the proper attitude
134400
Roll start
134420
Roll complete
134500
The LV passes the OL, east-to-west
134520
The LV is 2550m below and 560m north of the OL
134620
The LV is 2350m below, 190m west, and 480m north of the OL
134640
Ten minutes under rendezvous autopilot control .. about 20min to go
134720
The LV is 2100m below, 330m west, and 380m north of the OL
134820
Another roll is required to maintain the proper orientation of the face axis
134830
Roll start
134850
Roll complete
134940
Fifteen minutes under autopilot control .. halfway there
134970
The LV is 1500m below, 510m west, and 120m north of the OL
135080
The LV passes the OL, north-to-south
135240
Twenty minutes under autopilot control .. 10min to go
135250
Yet another roll is required to properly orient the face axis
135260
Roll start
135280
Roll complete
135300
The LV is within 1km of the OL
135310
The DOCK display velocity and attitude indicators are active
135380
The LV has arrived at the proper north-south position, 300m south of the OL
135485
The LV is 450m below, 210m west, and 295m south of the OL
135580
The autopilot has developed an oscillation in the vertical channel (F/B)
135590
The RCS throttle is set to MEDIUM to try to stop the oscillation
135690
And yet another roll
135720
The autopilot is having trouble
135730
*** WATCH the erratic behavior of the RCS thrusters in the status display
135765
The autopilot will be shut down early
135775
The remainder of rendezvous and docking will be performed manually
135785
The LV is under manual control
135965
The LV has arrived at the proper east-west position
136030
The OL is visible in the DOCK display window
136110
The LV is nearly on station, due south of the OL at a distance of 300m
136130
The LV is rolled into position for docking
136140
This concludes TUTORIAL # 3-3 .. the mission concludes with TUTORIAL # 3-4
