It optimizes tracking to observe all visible GNSS satellite signals, allowing for real-time reliable data accuracy and measurement results that deliver exceptional performance.


KRONOS T66 Equipped with a new calibration-free IMU module that leverages 4th generation pole-tilt compensation technology, KRONOS T66 enables surveyors to measure or stake out points even if they tilt the pole while walking. This allows surveyors to focus more on their tasks, resulting in faster completion of work.

Multiprotocol Internal Radio 

KRONOS T66 features a wide-band, low-power 410~470MHZ internal radio that supports various data transmission protocols within a 5km range, providing reliable and efficient communication even in challenging environments, with high performance.

Smart and High-tech Main Board

T66 GNSS equipped to Horizon 8580 mainboard built upon the Linux+I.MX6UL Cortex-A7 intelligent system platform this main board include Advanced processor with Qualcomm 28nm technology offering greater functionality and lower power consumption Perfect receiver size for long extended operation time, heat dissipation and high specification support.

Maximizes Survey Flexibility

The T66 GNSS receiver is equipped with an integrated NTRIP client, as well as internal Rx/Tx UHF and external radio modes. This versatile combination of features allows for maximum flexibility when it comes to conducting surveys. Additionally, the T66 GNSS receiver has preset survey modes that are easy to select or switch directly on the device. This is particularly useful in cases where project conditions change, allowing you to quickly adapt to new requirements. You can also save your favorite RTK survey modes, which will automatically start when the receiver is turned on, saving you unnecessary set up time.

Boosts survey with IMU

The T66 GNSS receiver is equipped with a built-in IMU that provides interference-free and automatic pole-tilt compensation in real-time. This innovative technology allows for high accuracy and a pole-tilt range of up to 60 degrees, without any magnetic interference. The T66 GNSS receiver's IMU is also easy to calibrate, providing a seamless and efficient solution for survey work that requires a high level of accuracy. By incorporating IMU technology, the T66 GNSS receiver can significantly boost the accuracy and efficiency of your survey work.

Internal multiprotocol radio

The T66 GNSS receiver is equipped with an internal multiprotocol radio that supports a 2W power output and allows you to join Tx/Rx with other brands. With the ability to easily change the frequency in software, you can connect to external or internal radios for maximum flexibility. The high-capacity battery of the T66 GNSS receiver has a minimal impact on working with the internal radio, making it an excellent choice for a wide range of projects. In fact, you can work with the internal radio of this receiver at distances of up to 6 to 8 km, providing you with the range you need for most survey applications.

Surpro Software

If you're looking for user-friendly and simple software for your survey projects, Surpro is an excellent choice. It has all the necessary features without complicated menus that could confuse surveyors or take up valuable time. All you need to do is turn it on and start working - the software automatically saves your last settings and starts searching for a fix as soon as you turn it on.

Surpro software also supports Google Maps and CAD maps for collecting points and CAD stakeout menus, making it a complete and easy-to-use solution for all your survey needs. Its simplicity and ease-of-use are particularly advantageous for those who are new to survey work or who require a quick and efficient solution
