How to Choose the Right RTK System for Your Needs

Your Guide to buying the best RTK

Overview

Real Time Kinematic (RTK) technology is a powerful positioning tool that enables surveyors, engineers, and other professionals to achieve precise results at a fraction of the time and cost of traditional surveying methods. This buying guide will provide an overview of RTK technology, along with the key features and factors to consider when purchasing an RTK system. Additionally, this guide will provide guidance on the types of applications and uses RTK technology is best suited for, as well as tips for researching, evaluating, and purchasing the right system for your needs.

Key features

  1. Accuracy: Shoppers should consider what accuracy they need from an RTK, as different models offer varying levels of accuracy. Some models offer accuracy of up to 1 cm while others might offer accuracy of up to 5 cm.
  2. Ease of Use: Shoppers should also consider how easy their chosen RTK is to use. Some models require complex setup while others are plug-and-play.
  3. Battery Life: Shoppers should also consider the battery life of their chosen RTK. Some models offer extended battery life while others might require recharging after a certain amount of time.
  4. Connectivity: Shoppers should also consider the level of connectivity their chosen RTK offers. Some models are compatible with certain receivers while others may require a different type of connection.
  5. Price: Finally, shoppers should consider the price of the RTK they are looking to purchase. Prices can vary greatly depending on the features and accuracy of the model.

Important considerations

Pros

  • Accuracy: Real-time kinematic (RTK) is an advanced form of GNSS positioning that uses fixed, ground-based reference stations to help correct for the errors in the satellite's signals, resulting in significantly higher accuracy than standard GNSS positioning.
  • Flexibility: RTK can be used in a variety of positioning scenarios, from surveying and mapping, to precision agriculture, autonomous vehicle guidance, and more.
  • Speed: RTK is also faster than traditional surveying methods, as it can accurately determine location in real-time.
  • Cost: RTK systems are relatively affordable, especially when compared to traditional surveying methods.
  • Durability: RTK systems are designed to be rugged and reliable, and can be used in a variety of weather and environmental conditions.
  • Scalability: RTK can be scaled up or down depending on the application, making it suitable for both large and small projects.

Cons

  • Cost - RTK systems can be expensive, and may require multiple components, like a total station and a reference station, in order to operate, making them a costly investment.
  • Time - RTK setup and alignment can be time consuming, and requires specialized training and experience.
  • Maintenance - RTK systems require regular maintenance and calibration, and require support from technicians if repairs or updates are needed.
  • Signal Strength - RTK systems require a strong signal for accuracy, so locations that lack access to a reliable signal may not be suitable for this type of surveying.

Common questions

  1. What is RTK?
    Real time kinematic (RTK) is a satellite navigation technique used to enhance the accuracy of position data derived from satellite-based positioning systems. It uses measurements of the pseudo-range from a fixed base station to a rover to precisely calculate the rover’s position.
  2. What are the benefits of RTK?
    The benefits of RTK include high accuracy, fast convergence, and the ability to maintain accuracy even under harsh environmental conditions, such as in areas with tall buildings or in areas with poor satellite reception. RTK is especially useful for applications requiring very precise positioning, such as surveying, mapping, precision agriculture, construction, and autonomous vehicle navigation.
  3. What components are necessary for an RTK system?
    The components necessary for an RTK system include a base station receiver, a rover receiver, a GPS antenna, and a radio or satellite modem (if using a networked solution).
  4. What types of RTK systems are available?
    RTK systems are available in two main varieties: stand-alone systems that use a dedicated radio modem to transmit the corrections from the base station to the rover, and networked solutions that leverage existing cellular or satellite networks to transfer the corrections.
  5. What should I consider when purchasing an RTK system?
    When purchasing an RTK system, it is important to consider the accuracy requirements of the application, the environment in which the system will be used, the size and weight of the system components, and the cost. Additionally, if using a networked solution, it is important to consider the availability of the network in the area.
