How to perform and upload a GNSS observation on an NAVD88 Bench Mark

By Frank Lenik, PLS

 

There are many ways of making GNSS observations these days, but not all of them will satisfy the needs of the National Geodetic Survey if you wish to have your data included in their Integrated Database or IDB. This process is like blue booking, but much easier.


To participate you will need a GNSS receiver capable of logging raw observations for a period of four hours or more. NGS suggests that you utilize a fixed height tripod but I use a conventional tripod and tribrach with adapter. You will also need a camera as part of the submission process includes photographs.
