physics - Optimizing Fly Overs in STK 10 -


i'm trying math find the orbit fly on greatest amount observatories anywhere in world. in stk 10, i'm plotting many observatories can , seeing ones hit - tedious process. i'm not sure stk able find orbit me once plot each observatory, new software. if able tell me if there function within stk can determine such orbit me, appreciate it. otherwise, giving me rundown on of math i'd need use determine orbit equally appreciated.

i can here (full disclosure, i'm vp of engineering @ agi, creators of stk). there's no magical function in stk (or other similar tool i'm aware of) this. can tell whether have "coverage", after it's optimization problem. here bunch of questions you'll need able answer frame out problem:

  1. fly on during period of time? 1 day, 1 week, 1 month?
  2. what definition of fly over? using constraint properties on each of objects. example, if trying model when satellite might in view of observatory can viewed through telescope might choose following constraints - directly sun light constraint on satellite (so it's lit , visible) , max ground sun elevation angle constraint of -18 degrees on facility using model observatory (this definition of astronomical twilight - e.g. it's dark enough out).
  3. what parameter trying maximize? number of observatories seen @ least once, total number of "accesses" (even if it's limited set of observatories seen often, total coverage time observatory?

a simple approach define "constellation" object holds facilities (e.g. observatories). build "chain" object containing constellation , satellite. there various "chain" reports give total access times or individual strand times.

you can vary satellite orbital parameters via connect model change orbit, request chain report , evaluate impact on coverage time. matlab, perl, python, (language of choice) script. or fancy , use our optimizer module takes out drudge work of mechanics of hooking up.

after you've framed out bit try giving our tech support team call. happy out.

angular - Ionic slides - dynamically add slides before and after -

hi i'm using ngfor create set of 3 slides while starting in middle i'm guaranteed able slide left or right on start. when slide right can simple listen reachedend , push slide array i'm looping. but have problem adding slide beginning. if same above , use e.g. array.unshift() or spread add item beginning, view think it's on position 0 , snaps view new slide. the code below work animates slide change index 1. slide = [0,1,2] //example loop slidechanged(event) { if(this.slides.isbeginning()){ this.slide = [this.slide[0]-1, ...this.slide]; this.slides.update(); this.slides.slideto(1) } } <ion-slides [initialslide]="1" (ionslidedidchange)="slidechanged($event)"> <ion-slide *ngfor="let item of slide"> <h1>slide {{item}}</h1> </ion-slide> </ion-slides> any appreciated! you can using ionslidenextend , ionslideprevend events slides . please

minify - Minimizing css files -

i want know how css files can minimized. currently, using external sites css minifier compress css files. however, after removing whitespaces, comments, etc, file sizes reduced 10-15%. how frameworks bootstrap manage make minimized versions kilobytes. as example, css is: body { background-color: #ff0; } the reduction goes 28 bytes 22 bytes other css files have lot more characters still smaller this. actually minifying code means it's remove thing code white space characters new line characters comments block delimiters it reduces amount of code has transferred on web , speed site load fastly.but unreadable format.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
