I may need to sharpen my pencil here... The answer I get from the people that do this all the time is that I need a tenth of a second accuracy, if the arc rate vs error in meters is linear that ...

I have talked to my colleagues about this and since I have only tracked "near Earth" objects (perigee, apogee 400 - 800 km) if I can get a tenth of a second that would be enough. That would allow ...

Leo, Roger - Thanks! If I could get accurate time to a tenth of a second I would be ok, as long as the observations can be definitely attributed to a particular satellite. I am always going to ...

Alen - Thanks, I am planning to do some testing such as taking photos of my phone (which runs an app named Time which gives very accurate time) and comparing with Exiftool. As long as I get time to ...

Roger - I do acknowledge this one and that one both. Feel free to not respond to any of my other questions.

By the way I did check the specs on some Nikons, Canons, etc and they don't mention this.

Ladies and Gentlemen - First, this has been an amazing site - I have learned a lot. Thanks to those folks that answered my niche questions. I need to take photos of the night sky and get the most ...

As others here have pointed out, this is an area of concern. These Starlink satellites should remind us of when we first snickered at a junk mail note, when we first got a robocall. I have been ...

The Kessler Syndrome mostly affects the "sun synchronous" satellites so far - such as Cosmic Background Explorer (COBE) which evidently had several collisions. We saw a collision for a WorldView ...

Exiftool was exactly what (I didn't even know) I was looking for, it gives a time of: Date/Time Original : 2019:04:30 23:09:55.78 which is better than I can probably set the camera to. I set it on ...

GGButcher - Thank you! I had hoped that the cameras recorded time to that accuracy, Exiftool is the answer that I had been looking for. Charles

a7sastro - Wow! That is amazing and would have taken me years to find. It looks like Exiftool might be a good utility. Thanks! Charles PS please think about taking up C++ programming.

All - Thanks for the replies so far! This seems like a very helpful group (I spend some time on C and C++ programming groups and they are much less helpful). I see that a7sastro and W5JCK have Sony ...

A group of amateur and professional astronomers around the world get "observations" from a group of satellites to maintain orbital parameters on them. BTW I have been in this biz since 1978 and I ...

Ladies and Gentlemen - The background: This is a niche question. I normally stick to analysis but have started taking some photos of satellites - as you might imagine I take them only at dusk ...
