|
|
Hello,
UFOOrbit works great, and I understand almost everything except how to enter time using R90 import format. By right clicking on a camera in Single Station mode, I can see the Universal Time that UFOOrbit has computed from the input data.
I use UFOOrbit on a computer that is NOT the computer used to collect data from the video cameras.
Examples:
(1) My part of Florida is GMT-5 (Eastern Standard Time). Using R90 format, I enter data using Eastern Standard Time and enter -5 as the Time Zone (Tz). But this makes the computed Universal Time wrong by one hour. It also puts the computed radiant in the wrong position. When I set Tz = -4, UFOOrbit correctly computes the Universal Time, and the radiant is in the right place.
(2) Another example is when I analyze meteor data from cameras in Arizona. Arizona is GMT-7 (Mountain Standard Time). I enter time using Mountain Standard Time, and set Tz = -7. In this situation, UFOOrbit computes Universal Time that is wrong by 3 hours.
(3) A third example is when I try to enter data using using Universal Time and Tz = 0. In this case, UFOOrbit computes a Universal Time that is wrong by 4 hours.
Please help me understand how to enter time using R90 format. Thank you!

Hi
Thank you for using UFOOrbit.
I have not understood you problem yet, but could you test again with R91 format?
just replace the format id "R90" to "R91".
R90 uses both timezone on the data and the Windows environment.
R91 uses only Tz in the data.

Hello,
Thank you for telling me about R91. I would like to use Universal Time instead of local time.
For a test of R91, I entered date and time using Universal Time (UT) so Tz = 0. This gives the right time, but now the date is D+1.
Attached are the test MCSV file, and a screenshot of the result.

Thank you for the sample. It will be the great help.
But the problem did not appear on my usual PC ((timezone = +9).
So, I changed to TZ=-4 and now I can see the problem.
Nobody noticed this problem for more than 10 years!
just wait for next post..

UFOOrbitV2 V2.53 was released.
There was a bug around process of crossing the date.
The problem could happen when the date is 1-24 on R91.
plese re-compute by V2.53 from below

Using Tz = 0, I can now import time & date as Universal Time. I also did tests using time zones from Tz = -23 to Tz = +23. Each test gave perfect results.
Thank you!
