BT-940N is a receiver with built-in high-precision module and four-star multi-frequency antenna.The receiver has the characteristics of high-precision centimeter-level RTK positioning, high antenna gain, miniaturization, high sensitivity, multi-system compatibility and high reliability. It comes with a wireless data transmission module that can transmit GPS data wirelessly. It can effectively meet the user's needs.
Built-in wireless data transmission module (or called radio), with its own data transmission module antenna, can transmit GPS data through wireless transmission, and wirelessly receive GPS data on the other end through wireless data transmission module.
Adopt multi-feed point design and completely symmetrical antenna structure, with a very stable phase center, reducing the measurement error of the antenna pair;
High gain, low standing wave ratio, obvious effect on low elevation signal reception, and can receive stars normally in the occasions with severe occlusion;
Equipped with anti-multipath choke plate, with anti-surge design, can effectively suppress the strong out-of-band interference signal to ensure the reliability of the antenna;
It is designed with UV-resistant PC material, which is both beautiful and at the same time ensures that the antenna casing does not change color for long-term outdoor use. It has an IP67 waterproof rating, high temperature resistance, sun protection and UV protection.
This receiver can receive GPS L1 / L2 GLONASS L1 / L2 BDS B1 / B2 Galileo E1 / e5b frequency and support RTK differential positioning, reaching centimeter level. To meet the needs of the current GNSS measurement equipment for multi system compatibility and high-precision users, it is widely used in the fields of geodesy, channel mapping, precision agriculture and marine survey, and can also be selected and applied in the military field according to the application conditions.

The receiver supports GPS L1C / A L2C, GLONASS L1OF L2OF, GALILEO E1B / C E5b, BDS B1I / B2I.
RX can be used to input commands, change the baud rate, frequency, output sentence and other parameters for GPS.
The receiver supports centimeter-level high-precision RTK differential positioning.
The receiver can be used as a base station or a mobile station.
If it is used as a base station, it only needs to be configured into the base station mode through instructions. The purpose of the base station is to be responsible for sending RTCM data to the mobile station in a wireless transmission mode through a wireless data transmission station.
If it is used as a mobile station, it can be directly used as a mobile station without any configuration. The mobile station first receives the RTCM data of the host station through the receiving end of the wireless data transmission radio station, and then calculates, it can enter the RTK differential positioning mode, and the accuracy can reach centimeter-level positioning.
The default baud rate of the module is 38400bps. If the frequency is increased, the baud rate will be increased accordingly, otherwise the data volume will be too large to transmit. In addition, the frequency is recommended not to exceed 5HZ.
The RTK light of the mobile station does not enter the RTK mode, and the light is off; enter the RTK Float mode, the blue light flashes; enter the RTK Fixed mode, the blue light is always on. The RTK light of the host station will be off at any time.
