Hybrid Tracking System for GPS Denied Environments (HYTS) Overview

Hybrid Tracking System for GPS Denied Environments (HYTS) is a Central Test and Evaluation Investment Program (CTEIP) project to develop a Global Navigation Satellite System (GNSS) based Time-Space-Position-Information (TSPI) capability that could be used in a Global Positioning System (GPS) denied Test and Evaluation (T&E) environment. It is to replace the obsolete Joint Advanced Missile Instrumentation (JAMI) TSPI system and support legacy JAMI sensors during transition. HYTS uses a Multi-Constellation Multi-Frequency (MCMF) GNSS sensor along with Ground Processing software to create and output TSPI messages to Government Test Range displays in real-time. Archived data can be post-mission processed to create accurate TSPI data products. HYTS takes advantage of GPS L1, L2 and L5 as well as Galileo E1, E2 and E5 frequencies. This paper provides a brief overview of the HYTS project and will investigate in more detail the efforts needed to transition from JAMI to HYTS in addition to addressing the solution of the JAMI parts obsolescence issue.
