Sitrec 2.1 New Features

Sitrec 2.1 contains numerous bug fixes, optimizations, and some significant new features. These are all driven by actual usage and user feedback. If you see something you want adding or fixing, then let me know

Optimization
  • Improved multiple tracks - so you can now drop in 100+ ADSB tracks and it should still perform well.
  • Satellite and Stars - should now perform reasonably (30 fps) when displaying all satellites and stars
  • Saving sitch with video is now much faster after the initial save.

New Features
  • Can now use a still image instead of a video
  • Added an MQ-9 Overlay to the look view.
  • Filtering Satellites by name
  • Lookup location (by name) for camera and target loctions
  • Speed graph for the camera
  • 110,000 stars
  • Stars can be filtered by magnitude
  • Allow roll when camera locked on a target
  • Celestial vectors move with moving targets
  • Links in the help menu for an ADSB replay or Google Maps for the current location (and time)
  • "Global Scale" on object menu lets you scale up all objects at the same time (to see where they are)
  • Show/Hide has new "Show all tracking in Look View"

Visual Improvements
  • Stars and satellites are more consistent in size on different systems
  • Satellites scale with distance, so you don't see too many invisible satellites
 
Is there a way in there to display the names of the satellites in the view as labels?

Like this?
 
I know you're removing the 'Night Sky' starlink viewer and incorporating it into the full sitrec, but I like the view it offers without the video. Is there a shortcut key to make the view in the new sitrec the same? ie left half-globe view, right-half look view?

Also, you've always said that sitrec wont work on mobile or tablet, but recently Iooked on an iPad Pro in Safari and it seemed to work ok. Have you done any optimisation for small screen or mobile browsers?
 
I still think there needs to be a 'quick start' process eventually for common scenarios

Paste in a set of in long/lat and it sets the camera there, at just above ground level and moves the terrain there etc, adjusting those things with sliders or pasting into small text boxes is fiddly, I am sure you are still at make sure it all works stage but it would be handy for quick setup

(Or View/View Preset/sideBySide)

No. But I guess the recent optimizations will have helped quite a bit. It kind of works on my iPhone, too. Quite reasonable for just viewing a sitch. I need to try to fix the zooming, as that seems like the obvious thing that goes wrong first.

I've disabled the default browser touch zooming and scrolling, which makes things a bit more stable. But I need to figure out some equivalents of mouse navigation. I guess I'll see what GE mobile does...

I've somewhat just done this with the Sitrec Chatbot
https://www.chatbase.co/chatbot-iframe/jm08ypN4zneL5S7wU2QOD

You can type in a location and local date/time and it will give links for ADSBx, FR24, Google Maps, and now Sitrec



The Sitrec link will open a new custom sitch with the look camera at the given location (needs fixing for terrain height).
 
New Feature: "Above Ground Level".

With the ball lightning case, I noticed the ball was going underground, so I added an AGL (Above Ground Level) mode that fixed the altitude relative to the ground over variable terrain, so you can make the target object follow a (straight) road. Here's a more extreme example:

 
I'm using the new version to do a search from back in March. I used the "load TLE" option but I'm not sure... it used to take several seconds and there was an indication it was happening, but now it seems to happen instantly and there's no message.

Is this working as expected? Broken?

Perhaps we could put the date of the TLE beside the menu item?

The first time satellites are fetched, it takes about 10 seconds. Subsequent fetches of the same thing will be much quicker, a second or less if in the local cache, or a couple of seconds if on the Metabunk cache

Then in the top right of the main view it will display the range of dates/times for the loaded satellites. (This is the actual min/max dates in the TLE, not the range requested)

I'll see about adding a "Loading" message.
 
Then in the top right of the main view

Ahhh, I don't use the main view so I never noticed this.

Ok, so now here is what started all of this. There is a video on Reddit that is obviously two sats passing between Alkaid and Mitzar on the morning of March 2 at 4:45 as seen from NJ (not any more specific than NJ, but it shouldn't make two much a a difference here.. Try as I might I cannot find anything that happens like that.

Given historical data like this, how close should the tracking be. Are we talking about a degree or less? Or 5 or more? My feeling is that with older data we should be able to get very close, we're not extrapolating forward.
