[Isocops] IBEX Orbit# 208 ATS (31 May 13 - 09 June 13) - v002 approval

Sun May 19 16:12:42 EDT 2013

All, 

I have looked at the orbit 208 ATS, 

IBEX_2013_151_o0208a_v002.scr, 

and I approve. 

There are no constraint violations in 

IBEX_2013_151_o0208a_v001.ccvr. 

The PL commands in the v002 ATS match those in the v002 STF, 

IBEX_2013_151_o0208a_v002.stf. 

Ascending and descending command sequences are consistent with each other and 15 Re ascending, the apogee maneuver time and 15 Re descending as determined from the OEF file, 

IBEX_2013_151_o0208a_v001.oef, 

and as verified with ibex_orbit. 

There is one star tracker outage. It starts about 2 hours before 15 Re descending and ends about 6 hours after the maneuver window opens (thus delaying the perigee maneuver). 

There are no moon in Lo FOV sessions. 

The ground station command sequences are correct and the timing and bit rates match those in the contacts file, 

IBEX_Orbit208Contacts.txt, 

for all contacts (3). 

We are doing battery cell balancing this orbit and the balancing commands are correct and offset by enough time from other commands. 

The inertial maneuver at perigee of orbit 207 left us pointing in safe directions for orbit 208 arc A ascending and descending sequences: 

ibex_rotate -o -u 0.378243,0.853272,0.358971 -w ibex-sun -t 2013/05:31:23:13:32

The inertial maneuver at apogee leaves us pointing in safe directions at the time of the maneuver and for arc B ascending and descending sequences:

The inertial maneuver at perigee leaves us pointing in safe directions at the time of the maneuver and at orbit 209 apogee:

No Lo O-mode. 

There is no overlap with orbit 207 commands by manual inspection or by checking at
