Monument Pins Overview
Design and Construction
There are a variety of marker designs. In general, markers consist of a post with a 1 mm dimple or intersecting crosshairs on top. The marker most commonly used by UNAVCO is the dimpled monument pin, or "Bevis pin." The Bevis pin is a 6-inch long, 1/2-inch diameter stainless steel pin machined with notches on the sides to prohibit rotation and a 1 mm dimple on the top. Machine and installation instructions are given below.
$15-50; varies depending on marker design.
Mount Commonly Used
Many mounts can be used with a monument pin, including the Tech 2000 mast, UNAVCO fixed-height spike mount, standard, short, or fixed-height tripod, or bipod. See the UNAVCO Resources: GNSS Antenna Mounts page.
