Antenna-integrated GNSS receiver 【Trimble R4s】

basic information

This is a receiver equipped with the necessary and sufficient functions for positioning, compatible with the currently operational GNSS (GPS, GLONASS, Galileo, BeiDou) and the Quasi-Zenith Satellite System (QZSS) dual-frequency. It supports 240 channels, allowing for adequate capture of incoming satellites. It is equipped with 256MB of internal memory, which is sufficient for static observations as well as for RTK mobile stations represented by VRS. The Trimble R4s GNSS receiver, which has almost the same thickness as the Zephyr antenna used in a separated configuration, weighs only 930g, making it ultra-lightweight. It achieves a long life of 10 hours with a single lithium-ion battery, making it suitable for a full day's work. The sides of the antenna are rubber-coated, designed to minimize shock in the event of a drop. Additionally, it is equipped with Class 1 Bluetooth, ensuring a reliable connection with the controller even in noisy environments such as urban areas or construction sites, freeing you from the stress of connectivity issues.

Detailed information

• 

  Both VRS and RTK can be observed, and RTK enables an environment without external radio equipment through Long Range Bluetooth. *Long Range Bluetooth achieves 100m (varies depending on the surrounding environment).

• 

  General GNSS receivers cannot perform positioning unless they can capture a certain number of GPS satellites among the many positioning satellites. However, the Trimble R4s can supplement with other satellite systems even with a low number of GPS satellites. It allows for observations to be made in accordance with the work pace on site, without worrying about the changing satellite configurations depending on the time of day, thereby improving performance.

• 

  With the use of the dedicated controller "LANDRiV Pro," hybrid surveying that switches between GNSS and total stations is possible. You can select the optimal sensor according to the work content and required accuracy, achieving improved work efficiency. Furthermore, we offer the "LANDRiV Pro + Report Option," which allows anyone to easily output GNSS reports. *Compatible with observation notebooks, records, accuracy management tables, and coordinate transformation calculation documents.
