HORUS TRACKING is a tool dedicated to satellite operators, space artifacts, and launch centers. The main goal of the product is to provide predictive analysis of conjunctions between space objects, offering a collision risk analysis during close approaches and proposing maneuvers that can be executed by operators to mitigate the risk. The proposed tool is intended for organizations involved in satellite and spacecraft operations, assisting in necessary maneuvers to avoid collisions between these operated spacecraft and other objects in orbit. The tool can surveil the satellites or space artifacts operated by the user and providing notifications about approaching objects. It features a dashboard that displays all the close approaches of each satellite and spacecraft over time. It includes a screen for analyzing passages of the same object near the satellite or space artifact, tracking how these passages are evolving over time, thereby enabling the analysis of potential suspicious behaviors of satellites or artifacts from other operators. It allows the user to request object tracking.

Earth from Space

Target Market

Satellite and space artifact operators, including companies operating satellite constellations.


The HORUS TRACKING system can be hosted in the cloud or physically within SAIPHER and receives data from various systems that can populate its database. It can be supplied with data from SAIPHER's own sensors or from partner entities and companies

The system user can access information about upcoming conjunctions involving their satellites and space artifacts up to 2 weeks in advance through a dashboard. The conjunctions are categorized based on the risk they present, which is measured by two variables: the Probability of Collision and the Miss Distance.


Miss Distance: This is the minimum distance of approach between the satellite/artifact and the other object.

• Probability of Collision: This represents the maximum probability of collision between the satellite/artifact and the object.


The system accepts object observation requests from the user. For this purpose, there is a main screen with a grid displaying all tracking requests made by the user, along with a world map showing the sensor network of the HORUS system.After the observations are completed, the user can click on the specific observation in the main tracking screen to be redirected to a screen displaying the observation data. On this screen, the user has the option to download the tracking files. The screen includes telescope images of each observation (raw data), as well as graphs of Right Ascension (RA), Declination (dec), and magnitude over time for each observation. Additionally, the screen provides the ephemerides generated from each observation.

Main Functions

The system provides a dashboard for upcoming conjunctions involving all satellites/artifacts of the user, providing the following information:

• Minimum distance between the satellite/artifact and the other object, also known as miss distance;

• PCollision Probability; Time of Closest Approach (TCA), indicating the exact time when the maximum proximity will occur;

• Analysis of multiple conjunctions of a single object in relation to the user's satellites/artifacts;

• Ability to receive tracking requests for space objects and update the information regarding the conjunctions involving them.
