When I add a table to a post, using the "Insert Table" button, then instead of the table the post just shows "No code has to be inserted here.". Let me post an example: Test1 Test2 Test3 Test4 When I edit the post it does show the "source code" of the table though: Test1 Test2...

A version of Sundance, the Apollo 9 LM software, is now available to be used in NASSP. It's not 100% the flown version, as we don't have that. Instead it's a sort of Frankenstein's Sundance, a version compiled from several revisions of Sundance. Ron Burkey from the Virtual AGC project has...

Didn't make a dedicated thread for the RTCC MFD yet, so here it is! The first post is a big update to the MFD, a completely updated Mission Plan Table (MPT). The MFD already had this feature, but it has been vastly improved now. To showcase the new features, I will do a walkthrough of a typical...

This thread is for discussing my Shuttle FDO MFD which I created to plan realistic Shuttle rendezvous profiles. It's not strictly limited to SSU, but you would need something to execute PEG-7 targets (TIG and LVLH DV vector), so it will mostly be useful for SSU. I've relased the source code...

I am running into a problem with trying to animate the rendezvous radar (as an example, it happens with other animations) for the NASSP Lunar Module. It works pretty well, except it snaps into a weird position at staging. When the descent stage is dropped a function calls ClearMeshes(true)...

Here a list of all the keyboard commands and controls for NASSP 8.0. There was a post like this on the old forum and there recently have been some additions (keyboard commands for the DEDA in the LM). So until there is a proper manual for NASSP 8.0, here a forum post with all the commands...

I've been working a bit on LM telemetry. Most of the data being sent in low bitrate should soon be available in the PCM. We have an old telemetry client, which currently only resides here: https://github.com/Thymo-/telemetryClient It was quite advanced for the CSM (you can display CMC data...

This thread is the "What needs done?" thread for NASSP 8.0. The V8 release branch is Orbiter2016. All development talk goes here.

Due to many issues with the Meadville Space Center forum (lots of downtime, lack of active admins and maintenance, lengthy user registration process made necessary by spam bots etc.) we have decided to move our active development to the Orbiter Forum. So all news, development and support for...

This question is specifically for NASSP, but might apply to Orbiter in general. I am in the process of analysing the behavior of the Digital Autopilot (DAP) of the Lunar Guidance Computer (LGC) during a docked burn on the Descent Propulsion System (DPS). Since we started being able to perform...

Next to this potential bug in Orbiter 2016 there is another problem with the implementation of accelerometers in NASSP. Part of the acceleration calculation is taking the global velocity each timestep and use the difference to the previous timestep to get the global velocity difference per...

Project Apollo - NASSP 7.0 has been released! This is the first official release since NASSP 6.4.3 on June 09, 2006. Project Apollo - NASSP (also known as NASSP or NCPP) is an add-on for the Orbiter Space Flight Simulator. Project Apollo simulates the Apollo missions to Earth orbit and the...

Orbiter 2016 introduced terrain to Orbiter. However, it seems the me that the basic shape of the Earth is still spherical. It doesn't matter if I put a Deltaglider at Cape Canaveral, the equator or the North Pole. In every case the radius is the radius as defined in the Earth config file, which...

The Apollo Guidance Computer had a routine to numerically integrate the state vector, the Coasting Integration Routine. If the Apollo spacecraft was somewhere between the Earth and the Moon, the routine would not only take the gravitation of the Earth into account, but also the Moon and Sun...

Lambert MFD is a tool that can be used to plan and execute realistic rendezvous maneuvers by solving Lambert's Problem. It is based on the lua scripts I released on Orbithangar a while ago and have been implemented by David413 in his Orbit Targeting MFD for Shuttle Fleet. My goal is to create a...

Or is there any way to get the equatorial radius with the API? The function oapiGetSize() returns the mean radius. The equatorial radius is used in Orbiter to calculate the gravitational potential. The gravity.pdf in the Technotes folder still says it uses the mean radius, but I think that is...

For a lua script I want to calculate a state vector from an initial state vector and elapsed time. I know how to do this without perturbations. If I want to include disturbing acceleration due to the oblateness (J2) I need the equatorial state vector. I think in C++ you can transform the...

Hey everyone, this is something I wanted to do for a long time and finally finished (kind of). I am quite new to the forum but a long time user of Orbiter. I also am from Germany and I hope my english is ok. This is a launch and rendezvous autopilot for Greg Burch's Medium Utility Lander...
