L1 STK Fundamentals Part 1: Build Scenarios

0:00 hello I'm rich and we are going to be looking at our fundamentals training I've been doing SDK training now since 2008 and that's why I'm here teaching you right now so this first lesson that we're going to do it's we're just going to introduce you into how to make new scenarios in SDK it's very basic what you're going to learn in this scenario is I'm simply going to show you how to set up a scenario we're going to go in and look at all the

0:30 windows in SDK and then we're going to understand some common tools but before I move on in any of this training I want you to understand there's so much in SDK we're not going to cover every single button in there but we're using the SDK free license and I'm going to pretty much cover everything that you get for free system toolkits provides a physics-based simulation environment for digital Mission engineering your system and component models can interact in SDK enabling you to measure

0:59 their performance in the context of the complete mission this approach supports collaboration with distributed multi-disciplinary teams across all of your operational domains and life cycle phases you're going to learn how to set up a new scenario understand the SDK windows and understand common tools one of the things that happens when people first start using SDK is they'll see our instructors when they open up the SDK the new scenario wizard they'll see a

1:30 little section here allows you to pick a central body and they're always like okay I don't know why I don't have the central body well I'm going to show you how to do this so make sure you have SDK open and running right now and once you do we're going to go up to the view menu and open up the view menu and you're going to see where it says planetary options if you don't have this on in the new

1:53 scenario wizard you won't see selections for the new central body all you have to do is open up the view menu click planetary options and now when we start up our scenario and we go into the SDK wizard you're going to see selections for the planetary options now before I get started here I do want to point out that this is a quick overview of the actual lesson that's in our help there's no way this is going to cover each and

2:20 every step it's just a quick review of what you can expect to see otherwise if you want details go to the lesson and follow it step by step we give you all the steps on how to do this stuff so we're going to create a new scenario in SDK so the first thing you do is you go to the welcome to STK window here and you click create a scenario when the new scenario wizard opens up

2:45 it's pretty simple we're going to give the scenario name so I'm just going to give this scenario a name and call SDK news scenario SDK new scenario there are some rules in here case doesn't matter 64 characters but other than that you can put anything in here up to 64 characters but it has to be one long word my description is just a way for you to keep notes you can write a sentence you can write a paragraph you

3:12 can write a book it's just ASCII text it's up to you I'm going to type in this is my first SDK scenario I'm just going to leave the default start time and what you can see in here is a start and stop time that you see here is your analysis time my start time is this is today my analysis my stop time is 24 hours from today I'm doing this on Eastern time my

3:43 computer set at Eastern time and what happens here is this is setting it at 1200 local or 1600 utcg think of that as Zulu time the utcg is just universal time again I'll call Zulu time there's other choices in here like if I open up that pull down menu select start time and then set to today that would start my scenario midnight local time today or the equivalent Zulu time which will be 0400 set to tomorrow which started at

4:13 midnight local time tonight or 0 400 tomorrow select date just opens up a calendar lets me pick a date and then finally the units the utcg is the default unit but these are all the other units that you can use and if you're in the fortnite you can even use those so once I get done here I have everything ready I click OK and my scenario is going to fire up

4:51 now one of the things you need to remember when you're using SDK is you need to make sure you save your scenario in a unique folder and you need to make sure that if you're doing anything heavy duty calculation wise it's usually a good idea to save before you do it all computers are different but there's nothing worse than make doing a lot of work in SDK and not saving and then having something happen to your scenario so it's real easy to

5:20 save in a unique folder if you go up to the toolbar and you click the save icon you'll notice that STK gives you a save as and it's going to create a folder for you called SDK news scenario that has the exact same name as your scenario object all you have to do is click save and now it's saving every time you click save it's saving your scenario in the SDK 12 folder now we're looking at our

5:48 SDK workspace we got a lot of information in our help about this which you can read so I'm just going to go over all this real quick one of the things that we're going to look at is menus and tools if I use the term menu anywhere in the training the menus are up here at the top then we have a bunch of tools in SDK these can be all set up the way you want them you can delete tools that you don't

6:12 use you can add tools that you need so for instance if I go up to the view menu and I go to toolbars you can see the tools that are already turned on because they have check marks and the tools that aren't on don't have check marks and you can add them or delete them from here another way you can do it is come over here to the toolbar area and right click and you can select them here too that's

6:36 a faster way to do it I have a tendency to like to do things where I only have to click once instead of twice this is called the insert SDK objects tool we'll look at this in the second lesson of our training so I'm going to go ahead and just simply close it we'll look at it in more detail later on over on the left is What's called the optic browser when you start adding objects to SDK Like Satellites ships

7:04 aircraft that kind of thing it's going to populate the object browser and it's going to be in a child parent relationship the overall parent of all the objects in SDK are your scenario objects and then you'll have scenario objects that attach to the scenario object and then scenario objects can also have attached objects again you're going to have parent child relationship we have the 2D graphic window and the 3D graphic window note if I grab the 2D window I

7:33 can't get it out of here it's stuck okay this is called the integrated area now you have choices I can go to either one of these windows I can right click on it and I can make them dockable I can make them floating if you make them floating you can move them over to another monitor you can go up to the windows menu and you can select tile vertically for instance and that'll put them side by side you can

7:56 add multiple 2D and 3D windows by simply going up to the view menu and adding new windows or you can duplicate windows that you already have and you might want to do that because you have property settings that you don't want to lose let's go ahead and look at the 2D window so I'm going to go ahead and maximize the window by clicking on this middle icon in the 2D graphic window and we can take a look-see here and see

8:21 what we got so if you look inside the window itself you can modify things in the properties but right now what I'm looking at here is the whole earth if you look real close you can see that I have a separation between direct sun and Umbra if you go up to the toolbar area here the first icon is your properties if you click the properties and we go down to the lighting page this is what's allowing you to see the

8:48 daylight and the night time the shading frame so you can always turn that off if you don't want it on it's just good situational awareness I'm going to cancel this I don't want to make any changes the grab Globe is this hand right here that's shaded it's already turned on all that means is that when that's on you can put your cursor on the 2D graphic window hold down your left Mouse button and you can pan

9:18 the next icon looks like a magnifying glass with a plus sign that's your zoom in icon if I click this I can go down to my map and draw a box now if you look real close you can see a little plus sign in that box that's going to recenter my map to that plus sign and wherever I put that box it's going to zoom into the extents of the box so I'll let it go let my left

9:41 Mouse button go and it zooms in I can pan I can further zoom using my scroll wheel so again you can zoom in using the zoom in icon drawing a box zooming in you can use your scroll wheel and you can pan to zoom out you can either scroll out or you can go up here to the magnifying glass with the minus sign and you'll have to click out as many times as you clicked in to get

10:12 out and see the whole earth again snap frame is this camera looking thing here and what this allows you to do is it allows you to create a view of your 2D graphic window and you can pick the image type that you want to save that picture as and these come in handy if you want to do things like create PowerPoint presentations Word documents and that kind of thing you can set up a nice little view in your 2D graphic

10:41 window and you can use it outside of SDK the next icon that's called Snap properties what this allows you to do is it allows you to say hey every time I take a picture inside my 2D window this is the format that I want to use next we have the measuring tool looks like a yardstick with an A and A B on it if I click the measure tool here I can I'll just like use the center of

11:08 Australia to the center of the United States if I hold down my left Mouse button and drag a line up to the center of the continental US and Let It Go if I go down here to the bottom of SDK if you look way down here in the bottom you're going to see it says distance from and then it's going to tell me the lat long that I put my cursor on and it's going to say 2 and it's going to

11:28 give me another latitude and longitude and then it'll tell me what the distance is the default distance is an SDK are kilometers and then it's also going to give me a bearing and that all comes down to which way that I draw my line so message viewer can give you some good information now understand when you measure like that it's only giving you an estimation of the distance because it's not going to be as precise as if

11:54 you put two points in the SDK using objects for instance and then measuring the distance between those objects this is just a way for you to get a quick idea how far apart places are on your map the central body icon sort of looks like a blue Globe here if I open this up I can change my central body into something else so for instance like maybe I want to look at the Moon maybe I want to be Mars

12:23 and this comes in handy we have some Advanced tutorials in SDK such as astrogator where we do an orbital transfer between the Earth and Mars so I have like one 3D graphic window up that shows Earth as a central body and I have another 3D graphic window up that shows Mars as a central body so you like I said one window can have Earth one window can have Mars make sure if you play with this that you

12:50 put it back to the central body you're actually using for your analysis so I'm going to switch it back to the Earth now I'm going to zoom back into the map here and when I do I'm going to start scrolling down you're going to see something here eventually as I get closer to the ground Bing Maps are going to kick in we have multiple maps and you can see

13:22 that now it's starting to kick in we have multiple Maps inside of SDK using Bing Maps if you go up here to this icon here this is your Microsoft Bing maps icon if you open this up you can see the Aerials the default if I select hybrid it looks like Ariel but now I have names of my roads and towns I can click Road and this looks like an old-fashioned map but I use it sometimes it comes in handy

13:52 Road dark I guess some people liked us it's not my thing I can't I can't really see it too well Road gray I can use that that's pretty cool and then finally the basic bitmap it really isn't cool at all in fact this is what you'll see if you work in a secure environment so those of you that have those really cool jobs in a skiff enjoy this View next let's look at the 3D graphic window

14:23 the best way to jump between your 2D map and your 3D map is to Simply go down here to these tabs and I'm going to click on the 3D graphic tab now the 3D window is a lot more fun than the 2D window doesn't mean you can see more on it because sometimes if I want to look at the whole earth I actually can use a 2d window better in the 3D window but if you go to the globe here and you

14:49 double click on this globe it's going to give you a latitude and longitude wherever you click again it's only as good as where you click but situational awareness is the key the next thing if I hold my left Mouse button down I can move the globe around and look at it from different perspectives later on when we're looking at objects you'll see that you can do that to objects and it looks neat especially if you're going to

15:13 take a picture of it now the reason why this is happening this way when I turn it's turning the whole earth is because I'm automatically locked on to the Center of the Earth if I want to zoom in and out there's a couple ways to do that I can use my right Mouse button hold down my right Mouse button and push my mouse away from me it goes out pull my mouse towards me it pulls it in I can

15:37 also use my scroll wheel that works too another thing you can do is you can hold down your shift key and you can hold down your left Mouse button and you can move things now sometimes this comes in handy because I might be zoomed into the Earth but I want to show a satellite out here on this side of the Earth so I just move it out of the way so I can see the view of

16:00 both objects and place it in the middle of both objects this is just something you're going to have to play with to understand how it works some people pick it up a lot faster than others I'm going to go ahead and go up here and you can see a bunch of tools that look like eyeballs I'm going to click What's called the home view the eyeball at the house and that just re-centers my view I've got an animation toolbar right here

16:26 if I click this button called start the Earth is going to start to spin underneath me if I click the double up arrows right here this is going to increase my time step if you go all the way down to the lower right hand corner of SDK you'll see that time step it defaults to 60 seconds actually defaults to 10 seconds I put it up to 60 seconds So the faster I go the faster the year turns

16:52 now if I don't want to watch the Earth turn underneath me if I want to stay locked onto a specific spot on the surface I'm going to go up here and click on the zoom in icon I'm going to draw a box around the area that I want to look at and now if I zoom out and I go up and I click the start button I will turn with the Earth as if I'm a geostationary

17:15 satellite I'm going to reset by clicking this red reset button in the animation toolbar and I'm going to start zooming way down close to the ground and when I do this as I get closer to the ground you're going to see a tiling effect what's happening is Bing Maps are kicking in but also so is terrain server we stream terrain but you

17:45 have to have an internet connection it's visual terrain if I hold down my left Mouse button and I move my globe I can see all the pretty mountains out in the distance it's just warm fuzzies for your eyeballs if you want to pan in the 3D graphic window you have to do like in the 2D window you have to come up here to the toolbar but this time you have to turn on grab globe go back to your map

18:16 hold down your shift key hold down your left Mouse button and you can pan if you don't hold down the shift key you just turn in circles and you get sick to your stomach other things we have here in the toolbar we have the view from two we're not going to go over this but what that allows you to do is View from one object to another the snap frame and snap frame properties work exactly the way in the

18:42 2D graphic Windows allows you to take pictures and set it up how you want to see those pictures the eyeball at the end gives you an Orient North so if you were turning this around and getting sick if you want to orient your map to the north just click the eyeball at the end and now the top of my map is north if my map is flat and I want to look straight down I can click Orient from

19:06 top and it reorients my map so I'm looking straight down to the ground again the home view the eyeball at the house takes me back out to this View I also have a flashlight so if I go over to the dark side of the earth which is not the Dark Side of the Moon like Pink Floyd did I can go ahead and turn on the flashlight and it gives me this make-believe light on the other side but

19:31 it's not analytical light it's actually still dark I'm going to turn that off if I turn the Earth around I can also use the measure tool it's different than it was in the 2D window because it also gives me a radius so I'll turn that on I can draw a line between two points but there's that radius gives me a bearing range right there in front of me when I let it go it still gives me that

19:55 information down the lower left hand corner of SDK and message viewer the windows central body works exactly the same I can go ahead and click well that was boring let me let me pick Europa europa's a little bit better let me go back to the Earth we'll talk about Globe manager in another lesson and my big Maps work exactly the same in the 3D graphic window as they did in the 2D graphic window finally I have the animation toolbar

20:28 that I was talking about up here again this allows me to start my scenario to play my scenario forward I can pause I can reverse my scenario and go backwards I can do step and reverse that'll work your scenario in one time step at a time step four goes One Step It Forward at a time and the double up and double down arrows allow you to increase and decrease your time step this window here the current scenario

20:54 time tells you what time you're looking at in your scenario finally the timeline view at the bottom of the screen this is a way for you to manually move through your scenario if you look down here I have this thing called the gray pointer if I put my cursor on it hold down my left Mouse button I can quickly move to an event in my scenario and we'll look at the timeline view in more detail in

21:17 later tutorials so this was a real quick introduction to SDK how to set up a quick scenario and some of the basic tools that you're going to use a lot when you're using SDK again make sure that if you want to see the detail you go back to the tutorial in SDK and you follow the step-by-step instructions so our training today I introduce you to the new scenario wizard on how to create a scenario then we went

21:49 into SDK I showed you how to save a scenario we looked at all the windows in SDK such as the 2D Graphics window the 3D Graphics window what was important about those two windows is each window had its own set of tools we looked at some of the other tools in the toolbar in SDK and we also introduced you to the timeline view so with that I hope you have a nice day and I'll see you in lesson two
