TrueTime's Mark V Delivers GPS SAASM P(Y) Code Time and Frequency

TrueTime Inc. (Nasdaq:TRUE), the leading provider of precision time and frequency products to the U.S. Government, today announced that TrueTime's Mark V time and frequency receiver has been introduced with GPS SAASM receiver.

The Mark V receiver incorporates Selective Availability Anti Spoofing Module (SAASM) P(Y) Code Precise Positioning Service (PPS) technology and provides it to the Department of Defense (DoD) and authorized U.S. allies. TrueTime has supplied the DoD with ultra precise Mark V GPS P(Y) code receivers since 1997.

The next generation Mark V takes full advantage of the precision, accuracy and anti-spoofing capabilities of the SAASM P(Y) Code. The 12-channel, all in-view receiver corrects for Selective Availability and provides direct Y-code acquisition. The Mark V is augmented with Receiver Autonomous Integrity Monitoring (RAIM) Fault Detection and Exclusion per RTCA DO-229 to protect against satellite/system anomalies and spoofing. Using TrueTime's Mark V, the DoD and authorized Government customers can obtain the most reliable GPS-based timing possible with accuracy better than 10 nanoseconds to Universal Time Coordinated (UTC).

"The addition of SAASM approval enhances our capabilities to serve the vital needs for national security. We are very proud to once again be chosen as a preeminent supplier to the U.S. Government for our robust time and frequency products. Our next generation Mark V SAASM-based receiver provides the security, reliability and serviceability that our customers demand," said Scott Davis, TrueTime's director of instrumentation sales.

The superior performance levels achieved by the 1U (1.75-inch) rackmount Mark V are the result of a 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 Pulse Per Second 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 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. The base models support up to four single-height plug-in modules. Using the optional 3.5-inch high chassis, up to 10 single-height modules can be accommodated. Remote control over a local network is easy using TrueTime's Telnet network interface plug-in option. Using Telnet, users can remotely check the status and/or configure the Mark V. Most operations possible via the RS-232 port are also possible via Telnet. The network interface option supports Dynamic Host Configuration Protocol (DHCP) so that no user intervention is required for the Mark V to be network ready. Password protection is provided to maintain secure access to the unit.

The Mark V is also available in an airborne configuration.
