CelesTrak

CelesTrak, founded in 1985 and based in Wailuku, United States, is a provider of space data services focused on space-traffic-management. The company operates as a free service, currently maintained by Dr. T.S. Kelso, and specializes in collecting, processing, and disseminating orbital data for a wide range of space objects. This data is critical for tracking satellites, debris, and other objects in Earth orbit.

While detailed information regarding specific technologies is limited in publicly available sources, CelesTrak’s core capability lies in its ability to compile and maintain a frequently updated catalog of Two-Line Element (TLE) sets. These TLEs are a standard format used globally for predicting the positions of objects in orbit, essential for collision avoidance and satellite operations. The longevity of the service, spanning nearly four decades, suggests a robust and reliable data processing and dissemination infrastructure.

Currently, information regarding specific missions or customers is not publicly available. However, the widespread use of TLE data within the space industry indicates CelesTrak’s data is likely utilized by a broad spectrum of organizations, including satellite operators, government agencies, and researchers.

CelesTrak’s unique value proposition lies in its provision of freely available, frequently updated orbital data. In a growing space environment with increasing congestion, access to accurate tracking information is paramount. By offering this service without cost, CelesTrak contributes significantly to space situational awareness and the safe operation of satellites.
