Three antennas are available for geodetic applications:
Each option is proven to deliver the performance network operators demand to ensure long-term success. In addition, three unique antenna designs provide the flexibility to reach a wide range of operational goals. The choice of what kind of antenna you ultimately choose is driven by your operational needs. Depending upon your priorities, it may become clear that one antenna style is a better fit for your particular application. Here are some questions to consider when choosing the antenna for your project:
Are you running a network or performing a geodetic campaign? Does an external organization dictate the antenna style that you must use? Are size and weight important considerations for installation or long-term deployment?
Although there are many different factors to consider and evaluate before making this important decision, Trimble has a solution that will meet your precise needs.
This is the first time I have post-processed logs. Prior to this job I was using horizontal only, RTK, corrections over radio type surveys.
Giving you some info on my job may help you help me.

This job is as follows.
I need the true elevation of the top of a hill to start an elevation survey with optical levels. I have loacted a Nat. Geodetic Survey (NGS) monument apx 6 km away.
Station monument info is here:
https://www.ngs.noaa.gov/cgi-bin/ds_mark.prl?PidBox=HB
I sat my base overy the monument, achieved green light status and connected to reachview. I entered the monument data into the fields where the lat, long, hieght and antenna height go, but then had second thoughts and turned off base corrections. The data I entered was NAD83 (as shown in the NGS data link) with an antenna height in meters.
I left the base logging data and drove to the job site 6 km north. Set the rover up in the same manner (except without entering any of that base data into reachview). I measured and wrote down the antenna height. I let the rover log data for exactly 1 hour. Then I took down the rover, drove to the base and took it down as well.
I do not care what the output from rtklib or rtkpost is, as long as I know what reference datum it is in. As long as I know that, I can find the geoid height to determine the true ortho elevation of the job site.
I&#;m just not familiar enough with the rtklib or rtkpost to know what it requires for input, what it sends out as output or what the reach logs record in. It may also be worthy for you to know that I also do not know exactly what a UBX or RINEX file are or what they contain.
