High Performance Timing System (HPTS) Land/Naval HPTS (rear panel connections) Brandywine’s High Performance Timing System (HPTS) is an industry-leading dual redundant modular system designed to provide time and frequency references for various military platforms. This modular system comprises a single rack mounted chassis, into which a number of modules are inserted to provide the required functionality. The HPTS receives a basic input reference from a GPS receiver, or external source and, in turn supplies a variety of time and frequency signals in a wide variety of available formats. The HPTS is a ruggedized system specified to provide full performance over a wide range of environmental conditions. A unique design feature of the HPTS enables it to distribute time reference signals over a wide area, while providing automatic compensation for propagation delays. The HPTS has been designed from the outset as a “network centric” product. All features and functions can be monitored and controlled by means of an Ethernet interface. Two Master Clock Modules (MCM), each utilizing a rubidium or ovenized quartz oscillator, are used to provide redundant time base information for synchronization and system operation. The subsystem components are connected to a backplane bus built into the systems chassis. Output signals are a variety of low voltage analog and digital type signals such as 10MHz, 1PPS, Have Quick and IRIG Time Code.
