Space Shuttle Ultra 1.25 Revision B development

No, I would say not. I could even test things outside SSU, just with a MFD to talk to the DLL.

It would just need to be done first. Do you have a checklist or so about the initial HST?

No, only the Press Kit and Media Resource Kit:

I just checked in an improved HUD version which simulates the shuttle HUD (and ignores Orbiter's default HUD). I also changed the Atlantis class to use the VESSEL3 base class, so it won't be compatible with Orbiter 2006 anymore.

I can't see this new HUD. All I get is the default HUD modes, with ALT and VEL printed at very edges of the screen.

You need to be in the VC mode. For some reason, in glass cockpit mode the default HUD is still drawn on top of the SSU HUD.

Also, make sure you're in MM304; other wise the default HUD will be displayed. Both the default landing scenarios should work.

OK, that worked. But you should file a bug report so that it can be fixed in the upcoming patch. Is there any way to incorporate landing guidance in the new HUD? Or will it just clutter up the very tiny space we have on that tiny HUD glass?

SiameseCat · Jun 29, 2010

HUD issue is a known bug (http://www.orbiter-forum.com/project.php?issueid=417).
It's possible to display landing guidance (I have some code which already does that for final approach). The main issues here are computing the guidance and designating the landing site. Designating the landing site would require a new CRT MFD display and new GPC code; I'm not sure if this is worth the effort until we have a more stable GPC simulation.

HST is coming along nicely. So, who wants to code it once the mesh/textures are done and checked in?

Does SiameseCat need more time for the Crawler? I could do it, I just need to do it along side the Mercury stuff. Currently learn to do some fun stuff with Lua scripts in Vessels, like defining subsystems by a special Lua script.

Found this little section on the HST/STS interface:

2.6.3 STS Interface Description

The orbiter provides the capability to relay commands to and TLM from the HST.
During both the deploy and maintenance missions, STOCC command messages are
transmitted to the JSC Mission Control Center (MCC), which interleaves the message
into the orbiter S-band or Ku-band operational forward link. Once received by the
orbiter system, the command message is processed through the systems management
GPC and the orbiter payload communications system and is retransmitted to the HST
via its LGAs in a manner resembling the GSTDN uplink mode of the HST MA
transponders. The command message is then processed further, as described in
Section 2.5.4.

2.6.3.1 Orbiter Processing of HST Commanding

The orbiter systems management GPC issues each serial digital command message
through the PSP/PI. A PSP transaction may contain up to sixty-four 16-bit command
words per message, and the GPC supersedes each message with a PSP configuration
message of five 16-bit words in length. This configuration message programs the PSP
to output the subsequent HST command data words in the transaction in a specified
manner via a specified route. For HST, the PSP output is RF only and has the following
characteristics per the PSP configuration message:
PSP command rate 1 kbps
PSP command data type NRZ-L
PSP subcarrier idle pattern Yes
Once the HST MA receiver has acquired the forward link carrier from the PI, the PSP
subcarrier idle pattern will be enabled to allow the HST to remain locked onto the PI
forward link. The PI will be configured to transmit at a nominal carrier frequency of
2106.4 MHz (channel 701).

2.6.3.2 Orbiter Relay of HST Telemetry

The HST return link is acquired by the orbiter PI, which receives the HST return link on
a nominal carrier frequency of 2287.5 Mhz (channel 701). From the PI, HST telemetry
is transmitted to the STOCC via orbiter S-band or Ku-band communication systems.
Data relayed via the S-band system are routed around the PSP (PSP-bypass
configuration) to the HST PGSC, then to the PDI for supporting 0.5, 4, and 32k
telemetry. See Figure 2.6-13 for PSP-bypass configuration. The PDI synchronizes
data to the data stream and buffer to allow the orbiter system to interleave the HST TLM
into the orbiter operational downlink. Once received at the MCC, the HST stream is stripped from the orbiter data and redistributed to the STOCC over the NASCOM network.

When available, the Ku-band wideband data system may be configured to relay the
HST return link to the TDRSS through the orbiter. The Ku-band system is used
primarily for downlinking 1024k HST telemetry and as a backup to the S-band
communication system for 0.5, 4, and 32k telemetry.
The nominal HST forward and return link carrier frequencies coincide with those of the
orbiter high-frequency mode. For this reason, the orbiter communications system must
be configured to low frequency during servicing missions.

Could someone post how to attach a payload to the bay so that you have to operate the A6 PL Retention Latch switches before you unberth a payload with the RMS?

SiameseCat · Jul 4, 2010

Here's a sample scenario showing the MPLM attached to the shuttle. The MPLM is attached to the LATCH1 subsystem (Payload 2 on the A6 panel).

Thanks. Any way we could incorporate the visual elements of the PRLAs? Also, do the PAYLOAD lines do anything anymore or are they superseded by the PayloadZPos in the mission definition files? In that case, I guess to clean up the scenario files a bit and reduce confusion, they should be removed.

SiameseCat · Jul 4, 2010

It should be fairly easy to add a mesh at each position in the payload bay where latches exist. The mesh file can be hardcoded or defined in the mission file.

I think this way is the one go. The HST is a bit of an oddball when it comes to shuttle payloads as it was only equipped with 3 trunnion pins instead of the usual 2 or 4!

So Discovery was equipped with 5 PRLAs, 3 on the port side and and 2 on the starboard side.

SiameseCat · Jul 5, 2010

What we'd need then is a mesh with all 5 PRLAs; the latch group handling the HST would be responsible for displaying the mesh. We could add a line (LatchMeshName0, etc.) to the mission file defining the mesh (if any) associated with each set of latches. Any comments?

Sounds good to me.

Three preview screenshots of the new HST, in the original launch configuration. Not yet done however, still have add the Magnetic Torque Bars, the EVA handrails, the FWD and aft Low Gain Antennas and the Aperture Door hinges, the third port side trunnion pin and need to close-out work areas on the Aft Shroud.

Urwumpe · Jul 10, 2010

Do you want the HST vessel to have the sensor modules as attachments so they can be replaced during EVA?

Do you want the HST vessel to have the sensor modules as attachments so they can be replaced during EVA?

That's the plan. I plan to borrow Donamy's WFC3 and use it as WF/PC-1 with the appropriate modifications.

Also have to check to whom I sent my SA3 and NCS meshes to.

How's work coming on making the mission files the only source for the ascent AP parameters?

Also, Ku band antenna deploy/stow speed should be changed. Although documentation states that the nominal deploy/stow time of the antenna is approx. 23 seconds, based on timings made of actual deploy/stow time I have made on videos that show the Ku antenna being stowed consistently shows the real timing to be approx. 18 seconds.

For the next official public release I think it should be aimed to be more supportive of a complete mission, IE it should have realistic pre-launch/launch ops, on-orbit ops and be capable of stand-alone entry and landing.

This should allow us to identify and eliminate a ton of bugs that surely resides in the code but just haven't been caught yet due to the vehicle not being mission ready.

The initial batch of missions could include the maiden flights of each vehicle(STS-1 for Columbia, STS-6 for Challenger, STS-41D for Discovery, STS-51J for Atlantis and STS-49 for Endeavour).

So we need the DFI pallet and IUS+ASE at least as active vessels.

Once we have this, I think we're ready for another release.
