Abstract

A Launch Acceptability Region [LAR] display system and method for a payload-releasing platform, the system being configured to be communicably coupled to a LAR computing module (104) configured to compute LAR data representative of a Launch Acceptability Region in respect of said platform based on a set of input parameters and predefined payload performance parameters, the system comprising: —an input module (100) configured to obtain or receive a first input parameter value in respect of a first of said input parameters, generate a set of second input parameter values in respect of said first of said input parameters, said second input parameter values being different to and at respective intervals from, said first input parameter value, and input said first input parameter value and said second input parameter values to said LAR computing module so as to cause said LAR computing module to compute, based on each of said first and second input parameter values, a respective LAR and output a set of LAR data, each data item of said set of LAR data being representative of a respective LAR and the input parameter value on which it is based; —an image data generation module (106) configured to receive said set of LAR data and generate therefrom a set of LAR image data, each data item of said set of LAR image data being representative of a respective data item of said set of LAR data; and—a display module (108) configured to receive said set of LAR image data and display, simultaneously, a visual representation of each LAR, wherein the relative positions in said display of said visual representations is based on their respective associated input parameter value.

First claim

The invention claimed is:

1. A Launch Acceptability Region [LAR] display system for a payload-releasing platform, the system comprising:
an input module configured to obtain or receive information relating to a target, a first value of at least one input parameter, and predefined payload performance parameters, wherein the at least one input parameter comprises one of altitude, velocity, or heading of the payload-releasing platform;

a LAR computing module configured to:
compute LAR data representative of a first LAR using the payload performance parameters, the target information and the first input parameter value; and
compute LAR data representative of a second LAR using the payload performance parameters, the target information and a second value of the input parameter, wherein the first LAR and the second LAR are regions in which a payload released from the payload-releasing platform could impact the target; and

an extrapolation module configured to receive said LAR data and extrapolate LAR data computed at input parameter values adjacent to the first and/or second input parameter values to generate intermediate LAR data;
said image data generation module configured to receive said LAR data for each LAR and generate therefrom a set of LAR image data; and
a display module configured to receive said set of LAR image data and display, simultaneously, a visual representation of each LAR, wherein the relative positions of said visual representations are based on their respective associated first or second input parameter values.

2. The system according to claim 1 , wherein said visual representation of each LAR includes an indication of its respective associated first or second input parameter value.

3. The system according to claim 2 , wherein said input module is configured, in response to receiving or obtaining said first input parameter value, to compute the second input parameter values based on a selected or predefined interval value.

4. The system according to claim 3 , further comprising an extrapolation module configured to receive said LAR data and extrapolate LAR data computed at input parameter values adjacent to the first and/or second input parameter values to generate intermediate LAR data, and include in said set of LAR data said intermediate LAR data for input to said image generation module.
