Normally, I run my static traverse beginning at two known NGS reference stations and proceed forward through my newly set control points. Today, I have a NGS station that is located in a not so friendly environment. I do not want to leave a receiver unattended at this location. All other points in the traverse are safe and I feel comfortable leaving a unit collecting data while I travel back to move a unit up. My question is..... and it may seem silly to those with more experience at this than me ....... does it matter which direction I run my static traverse? In other words, can I start my traverse on the unknown points and end on the NGS points? If this works I could end on the last NGS point in the seedy part of town and sit there with it.
I can't think of any reason why it matters what order you observe the points in a network in.
You should (I know my software does) be able to hold that last point as control and the software will adjust forward.
I have had/been a GPS bay sitter on certain projects, just like sometimes you need a robot sitter.
I take it that this is not an "OPUS Projects" question.

I couldn't think of any reason either. But I am a creature of habit and I like doing things the same way every time if possible. I always start on the known points like I am running a conventional traverse ..... old school roots I guess... partly just anal. I put my phone, wallet, keys, in the same pockets in the same order everyday..... Thanks Lee

I don't have a baby sitter today. So I was trying to work on my own and not lose any equipment in the process.

The reason it doesn't matter is that you're not really traversing -- you don't have any direct measurements between ground stations. It's all range measurements to satellites, so you can observe the ground stations in any order you want, though it's always a good idea to observe adjacent stations at the same time to minimize the errors in their relative positions.
The order worked out great. Watching the last setup while having lunch.
