The invention discloses a low-power-consumption high-precision positioning method based on an
intranet RTK technology. The method comprises the steps that S1, a
base station network and a service platform are deployed, and a terminal collects, formats, compresses and uploads Beidou original
observation data; s2, the platform collects data of the terminal and the
base station, constructs a differential
processing model, generates high-precision
differential correction information in real time, and issues the high-precision
differential correction information to the terminal through an internal network; s3, differential data are received and analyzed, data preprocessing, Kalman filtering,
ambiguity fixing and fixed solution
verification algorithm processes are sequentially executed in combination with self observation values, and
centimeter-level accurate position coordinates are finally solved; s4, low-power-consumption operation is realized through a
dynamic power management strategy and a time-triggered
sleep wake-up mechanism, and the stability, precision and update frequency of positioning are maintained in a high-speed and high-interference dynamic scene by using adaptive Kalman filtering and a fast convergence
algorithm; the method has the advantages of high positioning precision, low use
power consumption, wide application range and safe and reliable data.
