SuomiNet GPS Antenna Monumentation

Locating the GPS antenna is very important for determining the quality of data you will collect. The stability of the site and attenuation effects known as multi-path can degrade data collected. The time period of the data signals that will be analyzed is one of the primary factors which determines what type of anchoring is needed for the GPS antenna.

Monumentation for estimating atmospheric integrated precipitable water can be accomplished through mounts which provide stability to the antenna either on roof tops, or ground based installations, while monuments used for geodentic quality data generally require that the mount be anchored into bedrock or sufficient footings. Mounumentation on buildings is generally not sufficient for long term geodetic quality data due to building movement and setting over time.
