{{Note|Following the last update concerning GPC and DPS, it is now possible to choose in Space Shuttle In Game Options between Simplified and Advanced GPC behavior.
Here you will have the full explanation concerning the GPC reconfiguration to transition from OPS 1 (Ascent) to Orbital OPS2 using Advanced Setting.
 
If you want to skip this part and directly tansition from OPS 1 to OPS 2 GPC wise, you can go directly to the next part Post Insertion with Simplified GPC Reconfiguration

'''A good introduction book for those who want to appreciate and understand the work made on DPS'''

We are in Orbit, OMS burn completed, Cockpit reconfigurated, next step Post Insertion Items
 
It begins with GPC re configuration and OPS 2 transition
Here are a resume of what we want to achieve
 
 
GPC 1 and 2 will contain OPS 2 Guidance, Navigation and Control software (GNC)
GPC 3 will be put in Halt mode ( sleep). He will be freeze dried, which means that before going to sleep, a copy of the OPS 2 software will be loaded into the GPC in case of major failure of the others. Very deep level of redundancy here.
GPC 4 will receive the System Management ( SM) OPS 2 software and will be switch in Terminate mode ( it will not communicate on Flight Critical buses anymore unlike GPC 1 and 2).
GPC 5 that contains BFS software will be put in Halt mode, as no orbit software is contained in Back Up Software and Computer.
 
 
We want first to Freeze dried the GPC 3.To do so, we need to be in OPS 0 ( System Application only)
Problem is: It is still in the common set, and if we switch to OPS 0 in GPC3, the GPC 1,2 and 4 will be moved to OPS 0 also
So we need to switch off the communications between GPC 3 and the differents buses linked to him ( Flight criticals -FF-, and the one from central IDP/CRT )
 
 
For that, '''SPEC 0 PRO''' to acceed to the GPC Memory re configuration screen
 
[[File:Spec 0.jpg|1000px]]
 
 
 
Then, we reconfigure the  OPS 1 Memory configuration (MC G1) to have the GPC 3 out of the loop
 
[[File:MC 1 reconfig.jpg|1000px]]
 
 
 
 
We switch of the Back Up Flight Computer (BFC) which was displayed on CRT 3
 
[[File:BFC off.jpg|1000px]]
 
 
 
 
Now, time to see the changes  made to the MC1.<br />
 
''Every time we change something in the Nominal Bus Assignement Table (NBAT) through Spec 0, we need to do an OPS Transition or an OPS recall to see the changes applied'' (Which can be seen in'''SPEC 6 PRO''')<br />
 
We are in OPS 106, let's do an OPS recall which consist in calling back the same OPS than where we are<br />
So '''OPS 106 PRO'''<br />
We can see the changes, GPC 3 is not emitting on any buses, good job
 
[[File:GPC 3 out of FF and CRT.jpg|1000px]]
 
 
 
 
So we can now proceed to the freeze dried.
In the checks, the GPC to be freeze dried is written like that  '''G2FD'''<br />
By convention, it was always the number 3. But it can be an other one in case of failure.
 
To put it in OPS 0, we switch  to Halt (stby in the checks) then back to Run
 
[[File:GPC 3 OPS0.jpg|1000px]]
 
 
 
 
We want to display the GPC 3 somewhere (no CRT is polling it anymore), let's say on CRT 1<br />
For that, magic button is GPC/CRT key.<br />
'''GPC/CRT 31 EXEC''' will display the GPC 3 on CRT 1  with OPS 0 program
[[File:GPCCRT 31 EXE.jpg|1000px]]
 
 
 
 
We will load OPS 2 program (MC2) into it now<br />
'''ITEM 45+2 EXEC'''<br />
'''ITEM46+3 EXEC'''
 
[[File:MC02 load.jpg|1000px]]
 
 
 
And to store it, '''ITEM 47 EXEC'''  MC=G2 will appear once stored
 
[[File:GPC 3 FD completed.jpg|1000px]]
 
 
 
 
 
GPC3 is now freeze dried, let's put it in Halt for good
 
[[File:GPC 3 Halt.jpg|1000px]]
 
 
 
 
And the results of the Freeze Dried via Spec 6<br />
GPC 3 is in Halt mode, with OPS 2 software loaded, and it is not emitting on nay buses. Job done.
[[File:GPC 3 FD spec 6.jpg|1000px]]
 
 
 
 
 
Now, we will transition GPC 1 and 2 towards the Guidance and Navigation (GNC) OPS 2 Software<br />
Same as before, '''SPEC 0 EXEC''' on CRT 1 and we check that the NBAT is correct
 
[[File:MC 2.jpg|1000px]]
<br />
 
 
[[File:MC 2 configured.jpg|1000px]]
 
 
 
 
Then we can transition towards OPS 2 with [b]OPS 201 PRO[/b]<br />
We can verify that we are well in OPS 2 and UNIV PTG soft.
 
[[File:OPS 2 GNC.jpg|1000px]]
 
 
 
 
Next Step in the checks is to activate some Payload Bus on the electrical panel
[[File:PL bus activation.jpg|1000px]]
 
 
 
Then again, some Aft Station reconfiguration concerning different heaters ( RCS and OMS related)
It's a critical step here. If OMS pods and RCS freeze, we can loose burn and manoeuvring capabilities.
 
[[File:AFT-3.jpg|1000px|thumbnail|none]
 
 
 
 
 
Almost there, we need now to configure the GPC 4 to run the System Management (SM) software in OPS 2<br />
If not, we will not have access to various monitoring pages concerning all the Orbiter parameters
For that, choose a CRT where to display the GPC 4<br />
I choosed the CRT1<br />
Like before with the GPC 3, we do  '''GPC/CRT 41 EXEC'''
[[File:GPC 4 Prep.jpg|1000px]]
 
 
 
 
Then we reconfigure the NBAT<br />
GPC 4 will not emit on Flight Criticals Buses ( FF), it will not have a role in Guidance and Navigation, not part of the Redundant set composed of GPC 1 and 2<br />
It will emit only on Payload buses ( monitoring parameters like fuel cells, OMS, etc), CRT ( to display what it wants to show us), Launch Data buses ( to control the RMS) and Mass Memory ( to download the SM OPS 2 software)
 
[[File:MC4 GPC4.jpg|1000px]]
 
 
 
 
 
Finally, verify you are in SM major function on the CRT you are working on ( 1 here) and transition to SM OPS 2 via '''OPS 201 PRO'''<br />
 
Verify Antenna program
[[File:OPS 201 SM.jpg|1000px]]
 
 
 
 
 
 
Almost there, BFS needs to be secure now<br />
Display it via the switch we saw before on the pedestal (C3), you should see the BFS on CRT 3<br />
Then load it with '''OPS 0 PRO'''<br />
Unlike the GPC 3 , is not part of  Redundant set and Common set, so no risk of switching the others GPC in OPS 0 also
 
[[File:BFS OPS 0.jpg|1000px]]
 
 
 
 
 
And  switch off again the BFS CRT switch.<br />
 
You might have a poll error when you switch it off<br />
In that case, no worries, just do an OPS 2 recall on CRT 1  '''OPS 201 PRO''' to reload the correct NBAT, and GPC 2 should be polling again the CRT 3
 
[[File:TEST 4 BFS.jpg|1000px]]
 
 
 
 
 
Now, we gonna secure and switch off the CRT 3 not used in Obit<br />
'''GPC/CRT 03 EXEC''' to deasign any GPC of CRT 3 and turned it off
 
[[File:CRT 3 OPS 0.jpg|1000px]]
 
 
 
 
Let's check that the CRT 4 is turned on, with the Major Funtion in SM<br />
By convention also, this CRT is the prefered one in Orbit to access to the SM
 
[[File:CRT 4 sm.jpg|1000px]]
 
 
 
 
 
And final step now, GPC 5 ( BFS) will be put in Halt mode and GPC 4 ( SM) will be put in Terminate Output<br />
Terminate means it can't emit on Flight Critical Buses ( just a precaution  because in the NBAT, it wasn't assign on any FF)
[[File:GPC reconfig.jpg|1000px]]
 
 
 
 
Here are, fully configured ( DPS wise) for Orbit OPS<br />
 
 
GPC 1 and 2 for Guidance and Navigation<br />
GPC 3 FD<br />
GPC 4 for System Management<br />
GPC 5 Halt<br />
 
And CRT 3 turned Off
 
All of that is sum up on Spec 6 page ( PL 1/2 and L1 should have a Star in GPC 4 column like we had before, but it dissepears some times)
 
[[File:Final GPC.jpg|1000px]]
 
 
You can then resume the rest of Post Insertion

So, lets press '''OPS 2 PRO''' to load the software, we can see on the right CRT Spec 6 displaying the new configuration of the GPC.

{{Note|GPC transition from OPS 1 and 2 is completed, either in Advanced or Simplified option.
From there, tutorial is common to both options.}}<br />
