Real-time construction staking, like real-time surveying, can be a much better process than using other methods if done by a professional land surveyor. Having to process data after a survey with older technology takes valuable time and resources that don’t need to be utilized anymore. Using RTK (Real Time Kinematic) for construction staking is effective, and allows for real-time information and positioning so that the surveys and stake placement can be as accurate as conventional land surveying and done in less time. RTK stands for real-time kinematic, which basically focuses on utilizing actual information at the time of survey based on GPS information, rather than analyzing and processing data after a survey.

Using RTK for construction staking is becoming increasingly popular among surveyors because it allows for improved accuracy, faster survey times and quicker return to the builder for continuation of the building project in question. Construction staking is a critical part of the building process, because it helps to identify everything from land grades and utilities to positioning for corners, structure walls, and other parts of the building as per the site survey. Having a building constructed in the exact right place on a parcel of land is critical, which is where construction staking comes in handy.

There are many professional surveyors already using RTK for construction staking, and it is likely only a matter of time before all survey professionals rely on this type of information for their surveying needs. The more technology advances, the more advanced tools are created. With advanced tools and methods, surveying can be much more efficient, accurate, and take less time than ever before. This allows for fewer professionals to do more work and ensure the same or better results because of the innovations of technology like RTK surveying tools and processes.

Currently RTK systems can be integrated with convention or robotic total stations to allow the surveyor even more options during construction staking.

In practice, RTK systems use a single base station receiver and a number of mobile units. The base station re-broadcasts the phase of the carrier that it measured, and the mobile units compare their own phase measurements with the ones received from the base station. There are several ways to transmit a correction signal from base station to mobile station. The most popular way to achieve real-time, low-cost signal transmission is to use a radio modem, typically in the UHF band. In most countries, certain frequencies are allocated specifically for RTK purposes. Most land survey equipment have a built-in UHF band radio modem as a standard option.
This allows the units to calculate their relative position to millimeters, although their absolute position is accurate only to the same accuracy as the position of the base station. The typical nominal accuracy for these dual-frequency systems is 1 centimeter
