Infrastructure GNSS

Not all site locations require dedicated communications or power. Many sites come with existing infrastructure (power and/or communications, especially wired Ethernet) that can be leveraged to simplify designs and reduce station cost. In most cases, remote sites require dedicated power and communications equipment. However, due to the differential processing aspect of high-precision GNSS, there is usually a desire to have one or more stations deployed at sites on stable ground with good sky visibility for use as a Reference Station. In many cases, these locations are ideal for site infrastructure such as communications hubs, which creates a synergy for Infrastructure stations.

Infrastructure GNSS usually comprises a single GNSS receiver and antenna integrated into a NEMA4 enclosure equipped for direct connection to existing DC power and wired Ethernet. The primary purpose of this design is to reduce cost and simplify field implementation.  We have provided several variations of this simple and effective design.  It has been used widely in mine deformation monitoring projects, but could be effective for structural monitoring projects such as concrete arch dams and long span bridges.  

Customized for sites with existing power and communications infrastructure.  

Reduces cost and implementation burden for enabled sites.  

Often applied to GNSS Reference Station locations.  Also suitable for large structures such as bridges, dams and towers.  

GNSS antenna location is typically remote from receiver enclosure, requiring extended cable runs (i.e., from 3 to 150 meters).  

Historically developed as gray-box (NEMA 3x/4/12) enclosed systems.
