Unified Mission analysis Automation Tool
UMA is equipped with five different modules for different purposes.
The Unified Mission analysis Automation Tool (UMA) is an extension module created to increase the efficiency of operators and analysts by automating the workflow of space mission operations and operational analysis.
To improve the quality, reliability, and interoperability of the analysis, we have integrated and developed the Systems Tool Kit (STK) and Orbit Determination Tool Kit (ODTK), civilian products that are universally used in the aerospace field. A web browser-based visualization engine using the open source Cesium is included for easy sharing of UMA analysis results.
With UMA, routine operations can be performed regardless of the level of understanding of the analysis tool. Skilled operators can achieve significant efficiency and labor savings in their work by operating UMA and analysis tools in tandem.
Estimates the position and velocity of satellites and space objects based on observation data from ground stations and space stations (orbit estimation).
Space object initial conditions for orbit estimation can be defined from TLEs, orbital calendar files, CDM (Conjunction Data Message), etc.
The available observation data and observation data file formats are all available in the analysis engine, ODTK, which supports over 150 different observation data and 16 different formats. Please contact support for support of proprietary formats.
The Visibility Analysis function (Visibility Analysis) evaluates the performance of sensor assets using the overlay analysis function and calculates visibility opportunities for the TLE database.
The ground station analysis function (Ground Stations) allows new ground stations to be added via GUI or imported from STK ground station files. Multiple ground stations can be defined at once from a CSV file. To customize the field of view of ground stations, a separate menu GUI is provided to define onboard sensors and their characteristics.
The Relative Motion analysis function (Relative Motion) calculates event times for space objects. In addition, the operational analysis function calculates the solar phase angle history between a specific ground station and the target space object.

The automation function (Automation) enables automation of workflows other than those automated by UMA by executing STK’s proprietary “Connect Commend” command. For operational convenience, STK provides a function to retrieve the desired object from a TLE database file and a function to convert files of a specific format.
・TLE database ⇒ TLE databases that meet the conditions
・STK orbital calendar file ⇔ CCSDS OEM file
・TLE ⇔ OMM format file
・CDM ⇒ STK object
The Close Collision Analysis tool (CA: Conjunction Analysis) performs 1 vs. N and N vs.
The results calculated by the simple operation console are displayed in a table in a separate window, and the results can be saved to a CSV file or exported as a CDM file.1
1CDM export requires the covariance matrix to be analyzed
The Re-Entry analysis tool (RE: Re-Entry analysis) predicts re-entry from a specific TLE file or orbital calendar file.
Parametric analysis of the shortest and longest reentry times and positions is performed by performing a parametric analysis that affects the reentry time and position.2
The results are displayed in a table in a separate window, and a heat-map display can be used to guide the user to areas of high fall risk through the use of a cover-area analysis function.
2Re-entry analysis can vary widely depending on input parameters and environment files
The Situational Visualization Tool provides orbit and ground station visualization on the Cesium platform, an open source WebGL solution.
Visualize orbital calendar and TLE files output by UMA FD and UMA OT to compare the latest conditions analyzed with the catalog database. Added assets can be easily changed from the asset list to show or hide, display color, or select a display coordinate system.
