|Target Version||Fixed in Version||220.127.116.11|
|Summary||0003152: Add seconds to the hh:mm display above the "Next Pass" time graphs|
|Description||I'm getting feedback from AMSAT operators that HRD Satellite Tracking "is a few seconds behind the actual satellite pass."|
There's no way to know this for certain until we do some more testing. But for sure, we need to add seconds to the Next Pass AOS time that is shown above the time graph.
See attached image.
We would need this for either time format selected by the user - Local TIme or UTC (GMT).

||Pass times, to the second, are already available in the text view.|
If the detailed times in the text view aren't adequate for testing, it's not clear to me where they should be reformatted. The screenshots here indicate the "Next Passes" pane. Should the format be changed only there, or should it be added to the Next Passes view, as well?
||It’s not so much “testing”, but the time above the time graph should match the time on AMSAT’s charts so they’re easy to compare (given the concerns about our product being several seconds behind).|
The text view is available by following these steps. These instructions also highlight the difference between the "next passes" dockable pane and the "Next Passes" view.
1) Start Satellite Tracker
2) Click on the "satellite Definitions" tab
3) Click on the "Enable None" button to unselect all satellites
4) Mark the checkbox for any single satellite definition in the list to select it
5) Click on the "Next passes" button in the main toolbar. This creates a "next passes" view for that satellite. Note that the "Next passes" view is a different window, with a different implementation, than the dockable "Next passes" pane.
6) In the toolbar in the Next Passes view for the selected satellite, click the "Text" button in the toolbar.
7) This (eventually; it's quite slow) produces a text description of the satellite passes. For the satellite I happened to select, at my location, today, these are the first few lines shown:
Satellite AOS LOS Duration Peak AZ Peak EL -------------------------------------------------------------------- ALMASAT-1 2019-02-06 19:25:45 19:34:26 00:08:41 53.8° 24.8° ALMASAT-1 2019-02-07 10:33:21 10:42:54 00:09:33 114.9° 31.3° ALMASAT-1 2019-02-07 20:10:15 20:19:07 00:08:52 245.5° 33.3° ALMASAT-1 2019-02-08 11:17:56 11:27:23 00:09:27 303.4° 32.4° ALMASAT-1 2019-02-08 19:20:00 19:29:03 00:09:03 58.5° 58.6° ALMASAT-1 2019-02-09 10:27:33 10:37:15 00:09:42 122.3° 73.9° ALMASAT-1 2019-02-09 18:29:57 18:38:24 00:08:27 52.7° 18.8° ALMASAT-1 2019-02-10 09:37:42 09:46:49 00:09:07 112.6° 22.2° ALMASAT-1 2019-02-10 19:14:13 19:23:17 00:09:04 244.1° 51.0°
HH:MM times are shown in several places:
1) Next Passes view in elevation mode
2) Next Passes docking pane in elevation mode (as pictured above)
3) Next Passes view in radar mode
4) Next Passes docking pane in radar mode
5) Next Passes view in world map mode
6) Next Passes docking pane in world map mode
It's not hard to switch one (or all) of these to include seconds. Just need to know which we want.
I'm asking because the issue seems to say only the docking view, and only elevation mode should be changed and it doesn't seem like we'd purposefully ignore the other settings.
Further, if the goal is to be able to comapre to-the-second data to another site, it seems like the text view is really the easiest way to do that. The text view already shows seconds.
||I'll give this some consideration. But for consistency's sake, I'm not sure why the we're the only ones not consistently displaying ss in all the references to times for the passes. It leads to questions about being accurate, compared to AMSAT's data.|
There can be lots of rationale for limiting precision. I've no way of knowing why a previous decision was made. It seems best to focus on what we want in the future, and work towards that.
Once we decide what we want, I can implement it. Let me know.
Based on a side-by-side review of the text version in HRD SatTrack... to AMSAT's tracking site... it leads me to conclude that the feedback from the AMSAT operators is accurate. That is - HRD SatTrack seems to be several seconds behind the actual and accurate tracking.
There are some AMSAT guys here at Hamcation. I'mm going to see if they know who it is that understands the math well.
This may be a dumb question, but...
Can you slice or describe the formula used to calculate the path of the satellite's pass times?
This issue is about changing the formatting of the display of AOS and LOS times. If we're concerned about the accuracy of those times, I must insist that's a different issue and should be tracked separately, in its own Mantis issue. When we use a single Mantis issue to track multiple problems, measuring progress, testing, and resolution become more difficult than they should be.
Once that issue is opened, I can add notes about the math to it.
If we'd still like to add seconds to certain displays of AOS and LOS times in the Satellite Tracker, please let me know which places should display in that format and I can make the change. If we no longer want to consider that change, we should resolve this issue as "won't fix".
||I have created Mantis 3169 to track (LOL!) the accuracy concerns.|
The accuracy being a different issue, let's resolve to change our approach in SatTrack to where all times are displayed in hh:mm:ss. I was looking through images of competing software for this today and all of them use hh:mm:ss format.
So let's change 'em all.
All the time displays I could find now inclue seconds with this change set:
