Best Survey Poles, Range Poles, & More [2024]
Survey poles and range poles are tools used to ensure that the survey team can obtain location data more precisely while out in the field. These poles come in different lengths, are made of different materials, and are usually painted brightly for visibility over a distance.
In this article, we’ll share how survey sticks and poles work, list some of the best survey and range poles on the market, and explain how you can get best-in-class solutions for positioning accuracy in surveys, from NTRIP services to RTK solutions.
What are Range Poles, Survey Poles, & Prism Poles?
Let’s explain each of these pieces of survey equipment in more detail:
Range Poles
Range poles are survey equipment used to mark and align straight lines, establish survey points, and estimate distance. They are also used in excavation projects and to measure property lines.
Typically made of fiberglass, wood, or metal, range poles are designed for ease of use in various sites. They may also have pointed tips for easy insertion into the ground.
Survey Poles
Surveyors primarily use a survey pole to mount survey equipment, such as a GPS device or a prism. They are typically used to mark survey stations, establish sight lines, and provide a precise reference height for measurement.
Some survey poles have adjustable heights, so surveyors can extend the pole's height when necessary. If you’re using your survey pole with a GPS, you should consider integrating RTK corrections services for more accurate positioning information.
Prism Poles
A prism pole is specifically used for mounting prisms in a survey for precision measurement and data collection. These prisms enhance the accuracy of distance measurements by redirecting the path of the measuring beam.
Prism poles keep prisms above the ground, ensuring that the prism remains stable and at a consistent height for measurement accuracy.
GPS Poles
GPS poles are used for mounting global positioning systems (GPS) to elevate the GPS receiver above ground for better line of sight to satellites, improving the accuracy of location data and reducing obstructions that trees and buildings may cause. They are also often adjustable, so surveyors can increase the length to fit various situations.
Range Rods
Range rods, also known as ranging poles, are basically range poles longer than 12 feet. The increased length allows for visibility over longer distances and higher terrains. It also ensures that survey team members can maintain high levels of accuracy, especially in expansive areas. Range rods are best for large-scale mapping and surveying on large construction sites.
Regardless of your survey equipment, you need RTK corrections services for precise location data. Point One Navigation's solution, Polaris RTK, gives you access to over 1400 RTK base stations, <5-second network convergence times, and 99% uptime, giving you centimeter-level accuracy.

What are Survey Sticks?
A survey stick is a portable rod or pole used to mount a GNSS receiver. Surveyors use it to measure geographical positions in real time with precision. However, this precision can still be improved with RTK correction services.
How Do Survey Sticks Work?
Survey sticks support GNSS receivers, ensuring they are positioned correctly to receive satellite signals. The stick is designed to be stable and long enough to ensure an unobstructed path to receive satellite signals, minimizing errors in location measurement.

Access Ultimate Location Precision For Your Survey
Location precision is crucial in surveying, and achieving the highest level of accuracy often depends on the quality of the equipment used. Whether you are surveying over a short or long distance, you’ll want a survey pole that is durable and long enough. For portability, you should also consider poles with adjustable lengths.
These poles don't work alone, however; they are used to mount other survey equipment, such as GNSS receivers for drones, mobile mapping systems, and other systems that use inertial navigation for precise positioning and data collection.
Understanding the differences between absolute navigation systems such as Global Navigation Satellite Systems (GNSS), including GPS (Global Positioning System), GLONASS (Global Navigation Satellite System), Galileo, and BeiDou, and relative navigation systems such as Inertial Navigation Systems (INS), odometry used in robotics, and Dead Reckoning, can significantly impact your surveying accuracy and efficiency. However, you can still enhance your precision with GNSS corrections.
Point One Navigation offers best-in-class RTK corrections services for GNSS receivers. With its Polaris RTK Corrections Network, surveyors can access over 1400 RTK base stations, 99.99% uptime, and less than 5 seconds of network convergence time for centimeter-accurate positioning.
Also, Point One Navigation will soon launch a new product: local datums, which will further enhance the accuracy of positioning data.
