Symmetricom’s Mark V™ offers ultraprecise timing performance by using the GPS Precise Positioning Service (PPS) that takes full advantage of the accuracy and anti-spoofing capabilities of the P(Y) code. The Mark V corrects for Selective Availability and uses Y-code augmented with Receiver Autonomous Integrity Monitoring (RAIM) to protect against satellite/system anomalies and spoofing. In addition, it incorporates the latest Selective Availability Anti-Spoofing (SAASM) technology. U.S. Department of Defense and Government customers obtain the most reliable GPS-based timing possible with accuracy better than 10 nanoseconds to UTC.
The superior performance levels achieved by the Mark V are the result of a complete strategy based on accurate position determination, dual frequency GPS tracking, system integrity monitoring, multi-satellite ensembling techniques, and a high-stability ovenized oscillator.
Standard timing outputs from the Mark V include a 1 PPS accurate to less than 10 nanoseconds rms to GPS/UTC, analog IRIG B time code, and serial I/O time strings. Using the keypad or RS-232 port, users have control over a variety of time formats, configurations, and output options, including GPS and oscillator status and controls.
The very modular backplane architecture of the Mark V supports multiple time and frequency output options to address specific needs. These plug-in output modules can be incorporated at any time and significantly increase the clock adaptability to changing mission requirements. See the Options section for a list of the currently supported options. The base models support up to four single-height plug-in modules. Using the optional 3.5" high chassis, up to ten single-height modules can be accommodated.
The features of the Mark V make it the instrument of choice for critical mission applications such as:
· C4I
· Range Timing
· Satellite Communication Stations
· T1/E1 Primary Reference Sources · Network Synchronization |
