Drone State Estimation by Single Base Station - A simplified explanation of the abstract

This abstract first appeared for US patent application 17915941 titled 'Drone State Estimation by Single Base Station

Simplified Explanation

The patent application describes a method for estimating the movement of a wireless device in a network node using range and direction information. The method utilizes an interactive multiple modeling (IMM) filter, which includes three different models to estimate the device's movement: a constant velocity model, a constant acceleration model, and a constant position model.

  • The method obtains range information for a wireless device in communication with the network node.
  • The method also obtains direction information for the wireless device.
  • The method estimates the movement of the wireless device using the range information, direction information, and the interactive multiple modeling (IMM) filter.
  • The IMM filter consists of three models: a three-dimensional (3D) constant velocity model, a 3D constant acceleration model, and a 3D constant position model.

Potential applications of this technology:

  • Tracking and monitoring the movement of wireless devices in a network.
  • Enhancing location-based services by accurately estimating the movement of wireless devices.
  • Improving network management and resource allocation based on the estimated movement of wireless devices.

Problems solved by this technology:

  • Accurately estimating the movement of wireless devices can be challenging due to factors like signal strength variations and environmental conditions. This method addresses these challenges by utilizing range and direction information along with an interactive multiple modeling (IMM) filter.
  • Traditional methods for estimating movement may rely on single models, which may not accurately capture the dynamics of the wireless device. The use of multiple models in the IMM filter improves the accuracy of the movement estimation.

Benefits of this technology:

  • Improved accuracy in estimating the movement of wireless devices.
  • Enhanced tracking and monitoring capabilities in network nodes.
  • Better resource allocation and network management based on accurate movement estimation.


Original Abstract Submitted
