SAASM PRODUCTS OVERVIEW

GPS SAASM Two types of GPS receivers: Coarse Acquisition (C/A commercial) code and P/Y Code Selective Availability Anti- Spoofing Module (SAASM) C/A code = Commercial (70% application) P/Y code SAASM code = Military environment (30%)

GPS SAASM and order process Mission critical applications require protection from jamming and spoofing C/A code or SPS can be denied Established programs - BWC orders the receivers (cost is included in the product price) New programs – Gov-t provides the receivers via GFE or an authorization letter for BWC to order New directive waiver thru 2019

SAASM compliant PTS PTS SAASM – delivered over 500 units Redundant GPS (SAASM and C/A code) Rub oscillator comes standard Can sync from external GPS receiver 10MHZ, IRIG B, 1PPS outputs Ethernet port 10/100 BaseT, RS232 Web Browser control Timing accuracy <40ns RMS to UTC Built hardened for ship board, airborne and lab applications, NSN PN approved Older design
