Once again I throw down my pride in the persuit of knowledge. I've plans to cross portions of my county (6mi x 6mi township) and capture coordinates on each section corner using 3 PM2's. Once complete, plan to perform adjustment on entire Township using the Township corners as control.

Heres the rub. This process will take more than a single day of observations. How do I plan my sessions so that I don't fail the Network Connectivity test in Solutions? Is it as simple as occupying at least one of previous day's vectors so that their is a common vector between each day's work?

Humbly submitted,

Welcome to the world of network planning ;)>
You could leave one on a site and leap frog the other two. Or you could leave two stationary and move just one and go back and measure the vectors between the points. Either way it gets to be real fun.
I'd for sure measure a few of the vectors more than once to put some redundency in the network. If you don't have network connectivity from the beginning I think it would still process the vectors but not adjust. Don't know as I've always tried to maintain connectivity from the get go. You really wouldn't have to adjust until you are done with all the observations.
The Ashtech/Thales FTP site has a good document on network planning entitled "Practical GPS Surveying" that ought to give you some ideas.

You can occupy one and have connectivity. It is better to occupy 2 known at any time and jump ahead 1 unit at a time, that is redundancy. It makes for more work, but also a better solution. Considering what you get from GPS, longer occupation, better values for each location. Short vectors require less vector time. If you are going to do all the setup work alone. Jumping 1 unit at a time, your travel time from your third setup of the day, should be enough time for your vector 1 to 3. Pickup 1 move it to 4. End of and beginning of day is your only real extra time.

The days don't matter. Solutions doesn't care if you occupy part of the job today and part tomorrow or next week. Just load all the vectors into the same project, and it'll connect them automatically.

Caveat: Make sure that you use the same Site ID on a point that you occupy multiple times.

You already got some great ideas and I won't contradict any of them. The most redundant measurements are those where a second instrument setup is made in addtion to making an extra measurement. You must decide what will fit in your budget.

Make a dot plot of the points in your survey either with a map recon or by going out and marking each Site as a waypoint. Draw lines that connect the dots. The best lines are the shortest possible lines that connect all the dots. Multiple pathways to each dot are also very good things.

Every line you draw is a GPS vector that has two GPS receivers at each end of the line. How you organize the effort to connect the dots is a matter of resource management. What order you do them in does not matter. What end you start with does not matter.

Ashtech Solutions will combine all of your measurements in a network adjustment and crunch the numbers. All that is required is that you have your lines drawn in the map view like you drew them on your map.
