SureTrak Probability of Impact Display
- Created: Sunday, 01 January 2012
The SureTrak Probability of Impact Display software was developed for use during rocket launch operations. The software displays probability of impact information for each ship near the hazardous area during the time immediately preceding the launch of an unguided vehicle.
Wallops range safety officers need to be
sure that the risk to humans is below a certain
threshold during each use of the
Wallops Flight Facility Launch Range.
Under the variable conditions that can
exist at launch time, the decision to
launch must be made in a timely manner
to ensure a successful mission while not
exceeding those risk criteria. Range safety
officers need a tool that can give them the
needed probability of impact information
quickly, and in a format that is clearly
understandable. This application is meant
to fill that need.
The software is a reuse of part of software developed for an earlier project: Ship Surveillance Software System (S4). The S4 project was written in C++ using Microsoft Visual Studio 6. The data structures and dialog templates from it were copied into a new application that calls the implementation of the algorithms from S4 and displays the results as needed. In the S4 software, the list of ships in the area was received from one local radar interface and from operators who entered the ship information manually. The SureTrak Probability of Impact Display application receives ship data from two local radars as well as the SureTrak system, eliminating the need for manual data entry.
