Purpose-Built GPS Tripod for RTK Base Stations and Static Surveying
The SitePro 09-100S-FY is a professional-grade GPS antenna tripod engineered specifically for the demands of modern surveying and machine control workflows. Unlike general-purpose instrument tripods adapted for GPS use, this tripod is built from the ground up with reinforced aluminum legs, a wide-stance footprint, and a 3-position adjustable center staff that accommodates a range of antenna mounting heights. When your base station has to stay planted through wind, uneven terrain, and long observation windows, the 09-100S-FY delivers the rigidity and stability your data depends on.
Overview and Jobsite Applications
Whether you're setting a base over a benchmark for an all-day static session, deploying an RTK base for a machine control spread, or establishing control for a boundary survey, the SitePro 09-100S-FY handles it. The bright yellow finish makes it easy to spot across an active jobsite, reducing the risk of equipment contact from heavy machinery. The wide-stance aluminum legs drive firmly into soft ground and lock without flex, keeping your antenna phase center consistent from setup to breakdown. This tripod is a reliable choice for land surveyors, construction layout crews, and GIS field teams who need a dependable antenna platform day in and day out.

Job Applications
RTK Base Station Setup: Set the 09-100S-FY over a known control point and lock in your base antenna height using the 3-position center staff. The wide-stance legs hold firm while rovers work across the site, keeping your correction stream clean and consistent throughout the day.
Static GPS Observations: For control densification, boundary surveys, or geodetic work requiring extended observation windows, this tripod's positive-lock leg clamps and stable footprint keep antenna phase center displacement to a minimum over hours-long sessions.
Machine Control Base Deployment: When you're running grading or paving operations and need a base station that won't get bumped out of position, the reinforced legs and wide footprint of the 09-100S-FY hold their ground on active construction sites with heavy equipment nearby.
GIS Data Collection: Field GIS crews benefit from the easy height adjustability and high-visibility finish, making this tripod a practical platform for sub-meter and survey-grade antenna setups in both urban and remote environments.

Frequently Asked Questions
- What thread size is the center staff on the SitePro 09-100S-FY?
- The center staff uses a standard 5/8-11 thread, which is compatible with the vast majority of GPS and GNSS antennas, tribrachs, and survey mounting accessories currently on the market.
- Can I use this tripod for optical instruments like a total station or level?
- The 09-100S-FY is designed and optimized as a GPS antenna tripod. While the 5/8-11 thread is common across survey equipment, the flat-top head and center staff configuration are intended for antenna use. For optical instruments, a dedicated instrument tripod is recommended.
- How does the 3-position center staff work?
- The center staff can be set at three distinct height positions without adjusting the tripod legs, giving you a quick and repeatable way to vary your antenna height for different setups or to clear obstructions. Each position locks securely to prevent movement during observation.
- Is the fluorescent yellow finish just cosmetic, or does it serve a purpose on the jobsite?
- The high-visibility yellow finish is a practical safety feature. On active construction sites with heavy equipment operating nearby, a brightly colored tripod is significantly easier for operators and crew to spot, reducing the risk of accidental contact with your base station setup.
