CommSync II Modular Time details yet to be finalized by the government. What is P(Y) Code Direct? P(Y) Code is the encrypted military code that is part of the GPS signal structure. In order to receive this signal and receive accurate time and other necessary parameters, earlier GPS receivers were first required to acquire the C/A signal before acquiring the P-Code, as well as being crypto keyed.Today, the P(Y) Direct receiver can receive the military code in the absence of the civil C/A signal.This new functionality is important in todays tactical warfare sce- narios, in which the U.S. government may choose to make the civil (in the clear) GPS C/A signal unavailable through jamming or other means. The government document CJCSI 6140.01, OCT. 22, 1998 mandates the implementation of SAASM receivers to support the new military scenarios.The P(Y) Direct SAASM receiver to be featured in the CommSync II will support these requirements. Benefits INew tamper-resistant security design makes the P-Code receiver less vulnerable to compromise ISignificantly reduced logistics infrastructure for key distribution, handling, storage, and disposal IP(Y) Direct- acquisition with either L1 or L2 carriers provides for a robust terminal, able to come on-line and operate in the absence of the civil C/A signal. P(Y) Direct SAASM GTF Module with Direct P(Y) SAASM Intelligent GTF modules use a unique Zyfer learning algorithm to compensate for temperature changes as well as oscillator aging when not disciplined to a GPS or external input signal. Configurable Each GTF comes standard with a 1,5,10MHz or 1PPS input as standard for external synchronization. A GTF can be configured with the following features: I C/A Code GPS Receiver NP(Y) Code SAASM GPS Receiver 1 I Rubidium Oscillator I Quartz Oscillator N Call for availability 1See back page CommSync II Specifications Physical Height133.5 mm (5.25”) Width (Chassis)425 mm (16.75”) Mounts in 19” EIA rack Depth302 mm (16”) Weight20lb.
