The principle of iBeacon passive positioning technology and material positioning

The principle of iBeacon passive positioning technology and material positioning

In response to the need for high-precision positioning in positioning scenarios, and to overcome the adverse effects of indoor environment on positioning accuracy, this project proposes a weighted correction positioning algorithm combining trilateral measurement positioning. The positioning system first uses the trilateral measurement positioning algorithm to estimate the initial position of the user, and then combines the position estimation obtained from the initial positioning with the user's position

PDOP value of BeiDou satellite navigation system, BeiDou positioning module

PDOP value of BeiDou satellite navigation system, BeiDou positioning module

The actual constellation PDOP value of the Beidou satellite navigation system has reached the international leading level. The indicator parameters of a navigation constellation mainly include the number of available satellites in orbit and the Position Dilution of Precision (PDOP). The number of available satellites determines the coverage of the constellation's navigation signal, while PDOP is an important indicator used to measure the positioning accuracy of satellite navigation systems and the geometric strength of observation values, usually determined by the standard single point positioning observation equation.

SKG12 series pure BeiDou module serving BeiDou-3 satellite

SKG12 series pure BeiDou module serving BeiDou-3 satellite

Beidou-3 is the world's first satellite navigation system to provide three frequency signal services. The use of dual frequency signals in satellite navigation systems can weaken the impact of ionospheric delay, while using triple frequency signals can construct more complex models to eliminate high-order errors in ionospheric delay and improve the efficiency of carrier phase ambiguity resolution. In theory, this can improve carrier convergence speed. Therefore, the subsequent GPS will also adopt a three frequency signal system.

How long does the UWB tag stand by and what is the VDU1511 UWB tag

How long does the UWB tag stand by and what is the VDU1511 UWB tag

VDU1511 is a positioning card based on UWB (ultra wide band) technology. The main control chip usesNRF52832 to control the receiving and transmission of UWB signals. DW1000 positioning chip canrealize high precision positioning based on UWB TDOA (arrival time difference) by burning differentfirmware and cooperating with different UWB positioning base stations.

What fields can the single Beidou module be applied to

What fields can the single Beidou module be applied to

The single BeiDou module refers to a module for positioning based on China's independently developed BeiDou satellite navigation system. The single BeiDou module only receives BeiDou navigation satellite signals (including BeiDou-2 and BeiDou-3), and does not receive GPS, GLONASS, GALILEO and other satellite signals. RTK high-precision positioning is widely used.
